Another swipe takes the user back to the Zero Layer. It is also possible to go directly to the Zero Layer at any time via the home button.

The MBUX Virtual Assistant: intelligent, easy to talk to and empathetic, like a friend
With generative artificial intelligence (AI), the new MBUX Virtual Assistant revolutionizes the relationship between vehicle and driver. It is the next evolutionary step of the MBUX voice assistant and goes far beyond responding to commands. The MBUX Virtual Assistant enables complex, multi-turn dialogues – much like with a friend – and has short-term memory. It is activated by saying "Hey Mercedes." Based on ChatGPT4o and Microsoft Bing search, it unites the collective knowledge of the internet. For example, "Hey Mercedes, when does the cherry blossom season start in Japan?" – "And when does it start in Germany?" Users can speak naturally. For instance, the virtual assistant can answer questions like "Hey Mercedes, what is a black hole? Explain it so that children can understand."

Thanks to Google Gemini, the MBUX Virtual Assistant is also well-versed in navigation-related questions. The Automotive AI Agent from Google Cloud, developed with Gemini via Vertex AI, is specifically tailored to the automotive industry. It can access information from the Google Maps platform to provide users with detailed and personalized answers to questions about navigation, points of interest and more. For example, it can respond with suggestions to the question: "Hey Mercedes, I have a date today. Do you have any ideas for something special to do around here?"

The MBUX Virtual Assistant can retain context and switch between the Automotive AI Agent from Google and ChatGPT, depending on the topic being discussed. This means users can continue conversations and retrieve information throughout their journey. The virtual assistant is always present on the Zero Layer as a "living" avatar in the form of the Mercedes-Benz star.

During an active dialogue, it recognizes emotions and can respond accordingly. The star avatar provides visual feedback through color-coded animations to express moods and show empathy. In the default setting, it is blue (red on vehicles with AMG Line). If it detects the customer is in a positive mood, it turns green. If the MBUX Virtual Assistant notices pronounced happiness or excitement, for example, about a planned date, the avatar becomes more vivid and colorful. For anger or sadness, it changes to orange/red. With different animations, the Virtual Assistant also signals whether it is speaking, listening or processing. Movement, brightness, intensity and color interact seamlessly to communicate intuitively with the driver.

Individual entertainment for the front passenger
With the optional Superscreen, the all-new CLA offers the front passenger a 14-inch screen for individual entertainment. The continuously growing app portfolio⁸ includes video streaming platforms like Disney+, which offers a wide range of films and series from Disney, Pixar, Marvel, Star Wars and National Geographic. Since its launch, Disney+ has gained millions of subscribers worldwide and focuses on exclusive content to constantly expand its user base. With a user-friendly interface and a continuously growing library, Disney+ is a permanent fixture in the streaming market and is now available in the all-new CLA – and soon in other Mercedes-Benz models⁷.

The central display can only be used for this purpose when the vehicle is parked.

The passenger display screensaver can also be customized with personal images. Numerous safety precautions, such as eye-tracking technology, ensure that the driver is not distracted.

MBUX Surround Navigation: seamless integration of assistance and route guidance
Integrated visual communication also reaches a new dimension with MBUX Surround Navigation. Thanks to the deeply integrated architecture of MB.OS, the advanced navigation system shows a real-time view of the vehicle and its surroundings. The system seamlessly combines the driver assistance view with a 3D representation of the vehicle's surroundings and route guidance on the driver display. It shows other road users such as cars, bicycles, motorcycles and pedestrians. The integration of information into the driver display using 3D game engine graphics provides an extremely intuitive overview.

Drivers benefit from improved awareness of the vehicle's surroundings and operation of driver assistance systems. The display of route guidance in an environmental representation is particularly helpful in busy city traffic. Customers can see early on what lies ahead, such as behind the next turn. Buildings and other infrastructure are easily and quickly recognizable. The system also provides an integrated overview of vehicle status through real-time virtual-reality visualization, including the illumination of direction indicators, high and low beams. Acceleration and deceleration are visualized by the adjusted speed of the wheels.

Intelligent navigation with tailormade route guidance from Google Maps
In the new CLA, the navigation experience is based on Google Maps⁸. The unique navigation system offers Mercedes-Benz customers the best of both worlds: core services from Google Maps as a recognized benchmark and the trusted user interface from Mercedes-Benz. This offers the familiar Mercedes-Benz services for charging and parking. The navigation solution in the CLA, developed in partnership by Google and Mercedes-Benz, is one of the first systems to integrate Google Cloud's new Automotive AI Agent for in-vehicle use with Google Maps.

Mercedes-Benz Navigation with Electric Intelligence plans the fastest and most convenient route based on numerous factors, including charging stops. It dynamically responds to traffic jams or changes in driving style. Mercedes-Benz is continuously developing the energy forecast for Navigation with Electric Intelligence. In the future, predicted wind conditions along the route will be considered even more accurately based on the vehicle's height.

The system calculates energy demand to determine the route and takes into account the topography, route profile, ambient temperature, speed, heating and cooling needs. Other factors include the traffic situation as well as the availability, charging capacity and payment functions for charging stations on the planned route. The calculation takes place in the cloud and is combined with onboard data.

The intelligent navigation recognizes when a charging stop is necessary and automatically plans it to optimize overall travel time. In some instances, two short charging stops with higher charging capacity may be more beneficial than one longer stop. Additionally, the vehicle's charging settings are automatically adjusted by Navigation with Electric Intelligence and optimized for fast charging along the route. This includes preconditioning the high-voltage battery to ensure it is at the optimum temperature for DC fast charging at the proper time. The system also provides customers energy-saving tips.

Mercedes-Benz is the first automaker to introduce an integrated reservation function⁹ for charging stations at Mercedes-Benz charging hubs. In the U.S., Mercedes-Benz customers can use the integrated charging service MB.CHARGE Public¹⁰ to reserve a charging station in advance at Mercedes-Benz charging hubs. When route guidance using Navigation with Electric Intelligence is active, the vehicle automatically makes the reservation 15 minutes before reaching the charging station. For drivers, the reservation function saves time spent waiting and provides them the assurance of an available charging spot.

• Prepared for bidirectional charging (V2G and V2H)
• Center airbag available for the first time in this vehicle class
• High level of active and passive safety and a multi-stage high-voltage protection system

The all-new CLA with EQ technology is the compact sedan for the electric age. With remarkably low consumption and impressive range in this segment, it elevates the real-life practicality of electric mobility to a new level. Initially, the CLA 250+ with EQ Technology and the CLA 350 4MATIC with EQ Technology will be launched. By the end of the year, the model range will be expanded to include additional battery-electric variants and the CLA with a high-tech hybrid engine (see separate chapter).

With a range of up to 792 kilometers according to the WLTP cycle¹², the CLA 250+ with EQ Technology can travel a significant distance without charging stops. The 349-hp CLA 350 4MATIC with EQ Technology is positioned as the performance version at the top end of the model range. It combines efficiency with and outstanding performance, accelerating from 0 to 60 mph in just 4.8 seconds.

800-volt technology for fast charging
Technical highlights of the all-electric CLA include the 800-volt electrical architecture and advanced electric drive units with a two-speed transmission on the main drive at the rear axle. The 800-volt system maximizes efficiency and performance and can significantly reduce charging time in conjunction with the new generation battery. With EQ technology, the CLA can recharge with up to 300 kilometers¹² of range in just ten minutes. DC fast charging up to 320 kW is also possible.

The first two all-electric CLA models at a glance:

Newly developed electric drive system with 93 percent efficiency
With the main drive unit on the rear axle for optimal traction and driving characteristics, Mercedes-Benz brings a drive layout from higher model classes to the compact segment. The 268 hp electric drive unit with a permanently excited synchronous motor (PSM) on the rear axle was developed entirely in-house and is directly derived from the VISION EQXX unit. Battery-to-wheel efficiency over long distances is 93 percent.

The magnets in the rotor are arranged in a double-V shape. Another feature is the winding of the stator with hairpin windings. These measures contribute to an especially quiet drive. The PSM also has a significantly lower proportion – almost zero percent – of heavy rare earth elements compared to previous generation motors. The high performance power electronics are equipped with a silicon carbide (SiC) inverter to maximize efficiency. The transmission control and inverter are highly integrated into a single component.

Sprinter and marathon runner in one: two-speed transmission combines dynamics with high efficiency
The drive architecture includes a two-speed transmission on the rear axle, combining performance with efficiency. The first gear has a short ratio of 11:1, enabling excellent acceleration from a standstill and efficiency in city driving. The second gear (5:1 ratio) is designed for power delivery at higher speeds and efficiency in highway driving on the motorway for outstanding long distance range and comfort. The 130-mph electronically limited top speed is also achieved with two-speed transmission's second gear.

Shift points are based on the driving situation and the selected drive program. Additionally, the onboard optimization program continuously adjusts to current parameters such as battery charge level, power and driver requirements. Power is transmitted via claws (1st gear) or discs (2nd gear). The transmission also has special thermal insulation.

Additional power on demand: 4MATIC models with Disconnect Unit
The CLA 350 4MATIC with EQ Technology also features an 107 hp electric drive unit on the front axle. This unit is also a permanently excited synchronous motor (PSM) design and equipped with a silicon carbide (SiC) inverter. The front electric motor functions as a "boost" drive, activated only when the corresponding power or traction is required, depending on the driving situation or selected drive program. This is facilitated by the Disconnect Unit (DCU), which Mercedes-Benz is using for the first time on a vehicle in this segment.

For greater efficiency, the DCU can quickly decouple the front electric motor under low load so that the electric motor and components of the transmission are no longer engaged. This reduces parasitic losses at the front axle by up to 90 percent and increases electric range.

"Free" heat for efficient pre-conditioning: multi-source heat pump as standard
The all-electric CLA is the first Mercedes-Benz equipped standard with an air-side heat pump. It can utilize three energy sources in parallel as a multi-source heat pump: waste heat from the electric drive, the battery and ambient air. The air-to-air heat pump contributes to the high efficiency of the CLA by utilizing this "free" heat. It uses about one-third of the energy of a comparable auxiliary heater for the same output.

The multi-source heat pump also enables the CLA's exceptional charging performance by bringing the high-voltage battery to the ideal temperature range before DC fast charging begins. The battery is integrated into the intelligent thermal management system. When Navigation with Electric Intelligence is activated, the battery is preheated during the drive if necessary, reaching the optimal temperature for fast DC charging at the charging station. Mercedes-Benz ensures that efficiency does not come at the expense of cabin warmth in cold weather, keeping the interior at a comfortable temperature during fast charging.

Intelligent recuperation for maximum range
The all-electric CLA features a new one-box brake system. Previously separate components such as the brake booster with master brake cylinder and ESP control are combined into a compact module. The system optimizes recuperation of braking energy to help maximize electric range. The by-wire concept ensures consistent, confident brake pedal feel regardless of whether deceleration is achieved via regenerative braking or wheel brakes. Additionally, the new brake system meets the brand's high safety standards. In the event of a fault, the system switches to hydraulic operation, ensuring safe braking at all times.

To maximize efficiency, the majority of braking processes are carried out entirely through recuperation. The recuperation power up to 200 kW is possible. In principle, the models can even brake electrically to a standstill, thus recovering kinetic energy. The strong deceleration (up to 3 m/s² per axle) means more energy is recovered and, ultimately, contributing to a longer range. Recuperation is even possible during ABS braking such as on icy road surfaces.

The driver can use the selector behind the steering wheel to adjust recuperation power in additional to the drive program. Pulling the lever towards the steering wheel increases the level of recuperation to deceleration of up to 3 m/s². Pushing the lever towards the driver display reduces energy recovery accordingly. Further pressing the selector controls between "D+" and "D Auto" recuperation levels. The selected level of recuperation is shown at the bottom of the driver display. The driver can choose between four levels are recuperation:

• D Auto: Intelligent recuperation
• D+: No recuperation (coasting)
• D: Standard recuperation up to 1 m/s²
• D-: Enhanced recuperation up to 3 m/s²
  
  

All four recuperation levels are available as "Last Mode." In "D Auto", the ECO Assistant is automatically active. The ECO Assistant can use data stored in the navigation map as well as information from sensors and cameras to determine the anticipated route of the vehicle, depending on the vehicle's equipment. This system helps the driver to optimize their driving behavior to maximize efficiency and recuperation. It can take into account a variety of factors on a given route including roundabouts, tight bends, junctions, three-way intersections, inclines and speed limits. The ECO Assistant can also respond to other types of intersections or junctions based on when the driver actives the direction indicator.

When the system detects an upcoming route event or another vehicle is ahead, the ECO Assistant calculates the optimized speed profile based on distance, current driving speed and available route information. The "foot off the accelerator pedal" symbol appears on the driver display – centrally located in the driver's field of view. Following this prompt activates intelligent recuperation in coasting mode. If the ECO Assistant detects a stationary vehicle ahead, for instance, when approaching heavy traffic or a red traffic light, it can even bring the CLA to a complete stop.

Newly developed battery with silicon-oxide anodes and high energy density
The innovative battery system is based on a highly integrated modular architecture. The batteries consist of four large cell modules with hardcase cells and feature a compact and flat design. The CLA 250+ and CLA 350 4MATIC are equipped with lithium-ion batteries with an 85-kWh usable capacity. The cells' anodes are made from graphite mixed with silicon oxide. Compared to previous battery designs with conventional graphite anodes, the gravimetric energy density has been increased by up to 20 percent. The volumetric energy density of the cell chemistry is 680 Wh/l. Cobalt content has been further reduced.

The CLA provides power storage for the home: prepared for bidirectional charging
The all-electric CLA is prepared for the networking of electric vehicles with the power grid. When the vehicle is connected to a compatible bidirectional DC charging station, it becomes an energy storage unit that can store, for instance, solar power for later use. More importantly, it can also serve as a power supply, either Vehicle-to-Home (V2H) or Vehicle-to-Grid (V2G).

The bidirectional charging function will be available in the future through an over-the-air update. The use of bidirectional charging may be subject to market-specific conditions regarding legislation and the requirements of energy providers.

Class-leading aerodynamics with a drag coefficient starting at 0.21
Low air resistance means high efficiency, making aerodynamic performance particularly important for electric vehicles. Reducing the drag coefficient by just 0.01 increases the long distance electric range by approximately 2.5 percent. With a drag coefficient starting at 0.21, the all-electric CLA leads its segment.

The variation within the model range is minimal, partly due to the wide offering of aerodynamically optimized wheels. This includes, for the first time, a two-tone full cover for alloy wheels, which improves the drag coefficient by up to two points compared to a conventional rim. Additionally, the aerodynamics team has optimized the wheel spoilers forward of the front and rear axles across all wheel sizes, minimizing the impact of wheels and tires on air resistance.

The joints around the front grille and headlights are optimally positioned and partially sealed. The underbody concept from the EQS and EQE has been further developed for the CLA. The very smooth underbody is almost completely closed, with even the control arms and tie rods covered. The rear wheel well is fixed to the body, meaning there are no joints with surrounding components. It therefore does not move with the axle during wheel travel. The CLA also has impact management system to protect the battery, with fully integrated components that have also been aerodynamically optimized.

Comfort suspension with new three-link front axle and multi-link rear axle
The CLA comes as standard with a steel-sprung comfort suspension featuring a newly developed three-link front axle. The lower control arm comprises the transverse and thrust arms, both made of forged aluminum. As with a McPherson configuration, the strut guides the wheel and is directly connected to the steering knuckle. The third link, the tie rod, is part of the rack-and-pinion steering. The transverse steering gear is positioned in front of the wheel center, for optimal steering behavior and precise response. The steering knuckle, connecting the lower control arm with the strut and supporting the wheel and brake system, is made of cast aluminum. In addition to lightweight construction, high camber stiffness was prioritized for the steering knuckle, contributing to precise steering response and low noise.

The rear axle features a newly developed multi-link suspension – a design used by Mercedes-Benz on higher model classes such as the E-Class and S-Class.

High level of active and passive safety features – first center airbag in this segment
New in the CLA and for the first time in this segment, a center airbag integrated into the driver's seat backrest is equipped is standard. It deploys between the driver and front passenger in the event of a severe side impact, depending on the severity of the accident and vehicle occupancy.

Proven multi-stage high-voltage protection system and further developed battery early warning system
In addition to protecting the occupants of an electric vehicle as well as other road users, Mercedes-Benz places special emphasis on the protection of the vehicle's high-voltage system, which includes the high-voltage battery and the components to which it supplies power, such as the electric drive units and air conditioning. The high-voltage battery, high-voltage (HV) lines, and other HV components are designed to meet Mercedes-Benz's strict standards.

The battery housing is integrated into the crash concept as part of the vehicle structure. In addition, Mercedes-Benz has taken other comprehensive safety measures for the new generation high-voltage battery. These include appropriate spacing between the high-voltage battery cells as wells as adaptations to the structure of the cells and cell modules. The enhanced early warning system alerts vehicle occupants and triggers additional protective measures within the vehicle, including automatically closing side windows and ventilation flaps. A new sensor, positioned centrally in the high-voltage battery, monitors its status even when the vehicle is parked.

In the CLA, as with other models, Mercedes-Benz has implemented its multi-stage protection concept with eight elements of high-voltage safety. This ensures that there is no danger from electrical components for occupants, first responders and emergency services in the event of a collision. This protection concept is already proven in other all-electric Mercedes-Benz models, confirmed by findings from Mercedes-Benz Accident Research. In the event of a severe accident, the high-voltage system is automatically shut down, with a distinction made between reversible and irreversible shutdown.

Reversible shutdown occurs in minor accidents. If the driver attempts to restart the car after the automatic shutdown, an isolation measurement is automatically performed in the background. Restart is only possible if the system is error-free, ensuring that drivable vehicles remain operational. In severe accidents, where the vehicle is typically no longer drivable, the high-voltage system is irreversibly shut down. Irreversible means that only a specialist workshop can reactivate the vehicle.

During automatic shutdown, targeted discharging of the components ensures these pose no danger. There are also cut-off points for first responders to manually de-energize the high-voltage system.

New all-electric CLA reduces carbon footprint by 40 percent compared to its predecessor
The CLA is the forerunner of a new, innovative electric vehicle family from Mercedes-Benz. The carbon footprint of the new all-electric CLA is 40 percent smaller over the entire value chain compared to its non-electrified predecessor. By implementing further carbon-reduction measures in the supply chain and during battery charging, savings can increase to up to two-thirds.

About 40 percent of the aluminum used on the all-electric CLA is produced in electrolysis plants powered by renewable energy, saving a total of approximately 400 kg of CO₂ per vehicle. Various carbon reduction measures in the high-voltage battery cells also reduce the carbon footprint of the new generation battery by approximately 30 percent per cell. In addition to net carbon-neutral cell production, renewable energy is also used in the production of cathode, anode and cell housing materials.

Thermoplastics utilized in the interior of the new CLA also contain a high proportion of secondary materials. This adds up to four times more across the vehicle as a whole compared to its predecessor. A total of 50 percent of the secondary material in the thermoplastics comes from post-consumer recycled materials. For example, the jack mounts are made entirely from recycled car bumpers. The frunk well is constructed from approximately 70 percent recycled materials.

MB.CHARGE Public: integrated digital charging service
Mercedes-Benz groups all the functions of public charging into the digital extra MB.CHARGE Public¹⁶ (formerly Mercedes me Charge), offering numerous exclusive benefits to its customers. Just one charging account¹⁷ gives customers access to one of the world's largest charging networks. It also ensures user-friendly charging, regardless of public charging network. In the all-electric CLA, authentication is via the Mercedes-Benz app, the MB.CHARGE Public RFID card or directly via Plug & Charge¹⁸ at participating charging stations. Each charging session is automatically billed through MB.CHARGE Public. Mercedes-Benz also ensures maximum cost transparency at public charging stations. Before charging, users can view the specific costs per kilowatt-hour or per minute and the estimated total cost for a full charge on the MBUX display or in the Mercedes-Benz app.

Mercedes-Benz is continuously expanding the charging network through its own initiatives to build public charging infrastructure worldwide. Approximately 45,000 charging points will be created by the end of the decade through the global Mercedes-Benz Charging Network and the joint ventures IONITY, IONNA and IONCHI in Europe, North America and China. These will also be accessible via MB.CHARGE Public.

Green Charging: Mercedes-Benz is committed to charging with renewable energy
Green Charging is an integral part of MB.CHARGE Public in the U.S., Canada and Europe. If renewable energy is not yet available at the respective charging station, Green Charging uses green electricity certificates. These ensure that an equivalent amount of electricity from renewable sources is fed into the grid for charging processes. These are green electricity certificates from certified energy generation plants¹⁹ that are less than six years old²⁰. Wherever possible, the green electricity certificates are purchased and cancelled in the same country where the customer charges. This contributes to the further expansion of renewable energy.

Starting with the new generation of electric vehicles, Mercedes-Benz is extending its Green Charging initiative to private households. With intelligent home charging solutions, private customers can increase the share of renewable energy when charging their electric vehicles via a wallbox and reduce their carbon footprint.

Maximum flexibility thanks to modular architecture

The all-new Mercedes-Benz CLA: high-tech hybrid models with 48-volt technology

• Future hybrids capable of all-electric propulsion in city driving
• New four-cylinder engine from the FAME engine family with Miller-cycle combustion process
• New electrified eight-speed dual-clutch transmission with integrated electric motor
• New lithium-ion battery with 1.3 kWh capacity in flatpack design

All-electric models play a key role in implementing Mercedes-Benz's sustainable business strategy. However, the desires and mobility needs of customers in different regions of the world determine the pace of this transformation. Therefore, the all-new CLA will also be available in the future as a hybrid with 48-volt technology and an electric motor integrated into the transmission. The modular architecture of the CLA model family allows Mercedes-Benz maximum flexibility in the drive concept and production.

Visually, the CLA hybrid closely resembles its electric counterpart, allowing customers to choose between the two powertrains based on their lifestyle and preferences. One of the few distinguishing visual features of the CLA hybrid is the radiator grille with the Mercedes-Benz star pattern in chrome, framed by an LED surround.

The highly efficient hybrid powertrain was developed by Mercedes-Benz engineers in Germany according to proven quality standards. The state-of-the-art combustion engine in the CLA hybrid will initially be available in two power levels. Buyers will have the choice between front-wheel drive and 4MATIC all-wheel drive. Further details will follow later in the future.

All-electric propulsion and energy recuperation
The engine and transmission design is a compact design thanks to the cylinder spacing and the side-by-side arrangement of the electric motor. The electric motor, inverter and transmission form a highly integrated unit. A newly developed 48-volt battery with lithium-ion technology offers a capacity up to 1.3 kWh. Once again, the design is particularly compact: the battery cells and the DC/DC converter are integrated into the flatpack.

The electric motor provides intelligent support at all driving speeds and significantly improves acceleration, especially at low engine speeds. In city driving, when less than 27 hp is needed to propel the vehicle, the CLA hybrid can be driven using only electric power. Gliding, i.e., efficient coasting with a decoupled drivetrain, is possible up to a speed of approximately 60 mph. Another special feature of the electric motor is the ability for recuperation in all eight gears, recovering up to 25 kW of energy.

The torque produced by the combustion engine and the electric motor are additive, allowing maximum torque to be available over a wide range of engine speeds. The combustion engine can be started entirely by the electric motor and the disconnect clutch, eliminating the need for a conventional pinion starter. The start-stop function and switching between the two motors are almost imperceptible to the driver.

The electric motor, including the inverter, is integrated into a new, very compact eight-speed dual-clutch transmission (8F-eDCT). This development is called "eDCT" because the electric motor is integrated into the transmission and control of the mechanical system is electrohydraulic. An electric motor serves both lines of the dual clutch. Power transmission and disconnection are achieved via two drive clutches and a disconnect clutch. The wide spread of the eight gear ratios also contributes to efficiency, as it enables the engine to remain at optimal speeds.

New four-cylinder engine from the FAME engine family with Miller cycle combustion process
The combustion engine, developed by Mercedes-Benz, is a 1.5-liter four-cylinder gasoline unit. The engine, designated M 252, belongs to the Family of Modular Engines (FAME) and is suitable for a variety of vehicle applications.

Common features of the FAME engines include an all-aluminum crankcase with NANOSLIDE® technology and a cylinder head with a partially integrated exhaust manifold. The engines are also equipped with a turbocharger with a segmented turbine and switchable scroll connection. Other highlights include the compact charge-air path and the exhaust system mounted close to the engine in a one-box design, which is prepared for future emission standards. The electric refrigerant compressor with 48-volt technology, adopted from the M 256, reduces friction and allows the air conditioning to operate during electric driving and when the vehicle is stationary with the engine off.

The engine uses a combustion process based on the Miller cycle for efficiency. The relatively early closing of the intake valves reduces throttling losses and allows a high compression ratio of 12:1. This design helps maximize fuel economy, especially under partial load, which is very common in everyday driving. It also reduces NOx emissions.

The new engine-transmission unit has compact dimensions and is installed transversely between the steering knuckles. Another advantage is the exceptional NVH (Noise, Vibrations, Harshness). The engine is equipped with an extensive NVH package of foams and covers to reduce noise. The CLA also features the double-bulkhead concept, familiar from higher vehicle classes. Furthermore, the bulkhead insulation has been extended into the sides of the A-pillar and the floor.

All-new CLA production at Rastatt plant
The CLA hybrid is produced flexibly on the same line at the Mercedes-Benz plant in Rastatt as the all-electric CLA. Production is net carbon neutral²¹. The plant is supplied with 100 percent green electricity, most of which is purchased externally.

Rastatt is the lead plant in the production network for Mercedes-Benz vehicles in this segment, serving as a pioneer of the "Digital First" approach in the company's global production network. In preparation for production of the new model, the extensive conversion of an existing assembly hall was virtually represented and commissioned for the first time using a digital twin. The all-new CLA also marks the first series-production applications of the Mercedes-Benz Operating System (MB.OS), the company's proprietary chip-to-cloud architecture. Vehicle software is no longer transmitted via various hardware modules but via a central server of the Mercedes-Benz Intelligent Cloud.

Emotional expression of athletic power

The new Mercedes-Benz CLA: design and dimensional concept

• More spacious than ever: more headroom, legroom and the first modern Mercedes-Benz with a frunk
• Radiant front end: sporty shark-nose design with illuminated grille and central star
• Sensual proportions: fastback silhouette for outstanding aerodynamics and efficiency
• New luxury experience: avant-garde interior with high-tech elements like optional Superscreen

The new CLA is designed for the electric and digital age at Mercedes-Benz. As the first model of an entirely new vehicle family, it embodies the next evolutionary step in the Mercedes-Benz design philosophy of Sensual Purity. The Concept CLA Class previewed this dynamic appearance combined with extraordinary design elements. The production CLA is equally striking with an exciting interplay of intelligence and emotion, redefining desire.

With its fastback silhouette, the CLA features outstanding aerodynamics and efficiency. The long wheelbase (109.8 inches), short overhangs and distinctive GT rear are an emotional expression of athletic power. The car's sporty proportions are enhanced thanks to a sleek greenhouse, long hood with power domes and large wheels up to 19 inches. The car's muscular and athletic shoulders start at the front wheel arches and extend to the sculptural rear. The flared wheel arches and wide track (front/rear: 63.2 inches/62 inches) underscore the vehicle's dynamic presence.

The clear design language emphasizes the sculpted surfaces with reduced lines and precise joints. The striking character lines on the vehicle's profile create an interesting interplay of light and shadow. The powerful design conveys sporty confidence and modernity, giving the CLA a visual lightness. The meticulous attention to detail underscores the high quality and exclusivity of the new model.

More space at every seat and the frunk returns after 90 years
With an overall length of 185.9 inches, the new CLA is approximately 1.6 inches longer than its predecessor. The wheelbase has increased by 2.4 inches to 109.8 inches. The driver and front passenger have slightly more legroom (+0.4 inches). Passengers in both seat rows also have more headroom: an increase of 0.6 and 1.1 inches (front/rear). This is due to the higher roofline and the standard panoramic roof, which lets in plenty of light and creates a sense of freedom.

The CLA with EQ Technology is the first modern Mercedes-Benz with a frunk (front trunk). It offers approximately 2.5 cubic feet of cargo space, which makes it larger than in the Mercedes-Benz 130 (W 23) from the 1930s – the brand's first vehicle with a frunk. At the rear, the trunk of the new electric CLA provides 14.3 cubic feet of cargo space.
