Mercedes-AMG is putting performance firmly in the spotlight with the new AMG GT 4-Door Coupé, and this time the stage is Hollywood. Starting in October 2026, the high-performance electric four-door will headline Mercedes-AMG’s new global brand campaign, “TOO HARD TO RESIST”, alongside Hollywood star Brad Pitt.
Following the world premiere of the new Mercedes-AMG GT 4-Door Coupé in Los Angeles in May, the campaign brings together two very different expressions of performance: the controlled precision of a Hollywood production and the spontaneous, emotional experience of driving an AMG.
Brad Pitt, whose career has combined ambition, precision and performance, becomes the ideal on-screen partner for Mercedes-AMG as the brand introduces its latest performance flagship to a global audience.
When the Car Becomes the Star
Set in Los Angeles, the “TOO HARD TO RESIST” campaign begins like a classic Hollywood production. Cameras are rolling, the crew is in position and every scene is carefully choreographed.
But the arrival of the new Mercedes-AMG GT 4-Door Coupé changes the script.
Rather than simply serving as another prop on a film set, the AMG becomes the central character. The carefully controlled production gives way to a dynamic environment built around driving emotion, performance and the instinctive desire to get behind the wheel.
That idea is captured by the campaign’s tagline: “TOO HARD TO RESIST”.
The message is intended to describe more than the advertising campaign. Mercedes-AMG is using it to define the character of the new GT 4-Door Coupé itself, combining dramatic design with electric performance, agility and a strong emphasis on the emotional side of driving.
Brad Pitt and Mercedes-AMG: Performance Meets Hollywood
Brad Pitt’s involvement gives the campaign a distinctly cinematic character, but Mercedes-AMG says the partnership is based on shared values including ambition and performance.
The Hollywood actor joins the new AMG GT 4-Door Coupé at a significant moment for Mercedes-AMG as the brand expands its high-performance electric technology.
The campaign also builds on Mercedes-AMG’s previous promotional activity surrounding the car. In 2025, the brand generated attention with a Las Vegas stunt involving an AMG GT 4-Door Coupé prototype. The new campaign moves the story from spectacular stunt work to a more personal interpretation of what makes an AMG exciting to drive.
The result is deliberately positioned somewhere between cinema and automotive performance: a film set that ultimately becomes a playground for the car.
Mercedes-AMG GT 4-Door Coupé: Electric Performance With 1,169 HP
Behind the Hollywood imagery is a car that represents a major technological step for Mercedes-AMG.
The new Mercedes-AMG GT 4-Door Coupé is based on the company’s dedicated AMG Electric Architecture, known as AMG.EA. Rather than adapting an existing combustion-engine platform for electric propulsion, Mercedes-AMG has developed the architecture specifically around the requirements of high-performance electric vehicles.
At the centre of the technology are three axial-flux electric motors and directly cooled battery cells.
The system is capable of producing up to 860 kW, equivalent to 1,169 hp. Those figures put the new AMG GT 4-Door Coupé firmly into the territory traditionally occupied by the world’s most extreme performance cars.
The use of axial-flux motors is particularly significant. Compared with conventional radial-flux electric motors, axial-flux technology can offer a combination of high power density and compact dimensions, characteristics that are particularly valuable in a performance vehicle where weight, packaging and power delivery are critical.
Mercedes-AMG is also focusing heavily on battery cooling. Directly cooled battery cells are designed to help the high-voltage system maintain consistent performance under demanding conditions, an essential requirement for a car developed not simply for rapid acceleration, but for sustained high-performance driving.
Technology Proven by the AMG GT XX Concept
The new production AMG GT 4-Door Coupé’s performance technology has already been previewed by the Mercedes-AMG CONCEPT GT XX.
In 2025, the concept demonstrated the potential of the AMG.EA architecture during a spectacular record-setting drive at the Nardò test facility in Italy.
That demonstration was important because it showed Mercedes-AMG’s ambitions extend beyond headline acceleration figures. The company’s next-generation electric performance technology is being developed around high-speed capability, efficiency and the ability to sustain demanding driving conditions.
The production AMG GT 4-Door Coupé now brings that technological philosophy closer to the road.
A New Definition of AMG Performance
For decades, Mercedes-AMG has built its reputation around powerful combustion engines, rear-wheel drive dynamics and the unmistakable character of its high-performance cars. The AMG GT 4-Door Coupé represents a new chapter in that story.
Its AMG.EA architecture signals a fundamental change in the way Mercedes-AMG approaches performance. Electric propulsion allows engineers to rethink power delivery, packaging and vehicle dynamics, while the company’s focus remains firmly on creating an emotional driving experience.
That distinction is central to the “TOO HARD TO RESIST” campaign.
The message is not simply about how quickly the car can accelerate or how much power its electric motors can produce. Instead, Mercedes-AMG wants the new GT 4-Door Coupé to be perceived as a car that creates an instinctive desire to drive it.
In other words, the numbers are only part of the story.
From Hollywood Set to Driver’s Seat
The campaign was filmed alongside the world-premiere production in Los Angeles and was created by team x together with production house Tony Petersen Film. Simon McQuoid directed the project.
McQuoid’s experience in large-scale cinematic productions fits naturally with a campaign that deliberately blurs the boundaries between Hollywood filmmaking and automotive performance.
The central concept is simple: the script can be perfect, the cameras can be ready and every movement can be planned, but the arrival of a car with this level of performance can make the carefully constructed world of the film set difficult to resist.
The global Mercedes-AMG “TOO HARD TO RESIST” campaign launches in October 2026.
For Mercedes-AMG, it is also an opportunity to introduce a new generation of customers to a very different interpretation of the performance car.
The new Mercedes-AMG GT 4-Door Coupé combines the visual drama expected from an AMG flagship with an all-electric powertrain capable of producing up to 1,169 hp. With AMG.EA technology, three axial-flux motors and directly cooled battery cells, it represents one of the most important steps yet in the company’s transition toward electric performance.
And if Mercedes-AMG’s message is anything to go by, the hardest part may not be resisting the car’s performance.
The Mercedes-AMG CLE 646 Spezialanfertigung is not simply a more powerful version of the CLE Coupé. It is a comprehensive, hand-built transformation designed around one overriding objective: maximum driving dynamics. With a 646-hp V8 biturbo engine, rear-wheel drive, a significantly widened body, adjustable racing suspension and more than 250 kilograms of downforce at top speed, this road-legal coupé is engineered to feel as convincing on a winding country road as it is on a closed circuit.
Limited to just 30 examples worldwide, the CLE 646 Spezialanfertigung is the second model in Mercedes-Benz’s exclusive Mythos Series. Every car is comprehensively rebuilt at Mercedes-AMG’s headquarters in Affalterbach, and the entire production run was sold out before the model’s world premiere.
A CLE Reimagined as a Complete Performance System
The project began with an idea inside AMG’s engineering department rather than a conventional product-development brief. A small team initially built a prototype to answer a straightforward question: how far could the CLE be pushed toward maximum driving performance?
The answer was not a collection of optional upgrades. AMG engineers reworked the vehicle as an integrated performance system, combining a more powerful engine, a bespoke chassis, extensive lightweight construction, a wider bodyshell and purpose-developed aerodynamics.
The current Mercedes-AMG CLE Coupé provides the technical foundation, but the Spezialanfertigung is extensively modified. Approximately 170 kilograms have been removed compared with the donor vehicle, while the bodyshell itself has been reinforced and widened. The result is effectively a new performance machine, rebuilt to Affalterbach manufactory standards.
That extensive reconstruction explains the model’s name. “Spezialanfertigung” translates roughly as “special manufacture,” and in this case the designation describes far more than a cosmetic special edition.
646-HP V8 Biturbo with a Flat-Plane Crankshaft
At the center of the CLE 646 Spezialanfertigung is an extensively enhanced version of AMG’s M177 EVO 4.0-liter V8 biturbo engine. The model’s name reflects its output: 646 hp (475 kW), with 850 Nm of torque available across a broad engine-speed range from 2,500 to 4,500 rpm.
The engine uses a flat-plane crankshaft, which reduces rotating mass and improves its ability to build revs. AMG has also developed dedicated engine mapping to sharpen throttle response and make the power delivery more immediate.
This is not a power increase designed merely to inflate a specification sheet. The engine has been integrated into a wider package intended to deliver a more responsive and engaging driving experience, particularly when the driver is working through corners and modulating the throttle.
Three Cooling Circuits for Extreme Loads
The V8’s thermal-management system has been enhanced to cope with the demands of intensive racetrack use and high ambient temperatures. It employs three separate cooling circuits:
A high-temperature circuit for the engine.
A low-temperature circuit for charge-air cooling.
A second low-temperature circuit for transmission oil and the 48-volt components.
The system is designed to maintain thermal stability under sustained loads, helping the engine and drivetrain deliver consistent performance rather than merely a brief peak output.
Titanium Exhaust and Akrapovič Collaboration
The V8’s character is reinforced by a bespoke high-performance exhaust system with increased flow capacity and a deliberately emotional sound signature. The cold-end design was developed in cooperation with Akrapovič, while extensive use of titanium contributes to the vehicle’s weight reduction.
The result is intended to preserve the unmistakable AMG V8 soundtrack while supporting the car’s broader lightweight and performance objectives.
Rear-Wheel Drive Replaces AMG 4MATIC+
One of the most consequential changes is hidden beneath the bodywork. The donor vehicle’s AMG Performance 4MATIC+ all-wheel-drive system has been removed entirely.
The CLE 646 Spezialanfertigung sends its power exclusively to the rear wheels. That decision reduces weight, but more importantly, it fundamentally changes the car’s dynamic character. The driver becomes more directly involved in managing the relationship between engine torque, rear-axle traction and cornering attitude.
An electronically controlled limited-slip rear differential varies its locking action to optimize torque distribution between the driven wheels. This improves traction, stability and overall dynamic performance, while also allowing controlled drifting under suitable conditions.
It is a deliberately less forgiving configuration than all-wheel drive, but that is precisely the point. The Spezialanfertigung is designed to provide a more direct connection between the driver and the car.
AMG SPEEDSHIFT TCT 9G and 310 km/h Top Speed
Power is transmitted through AMG’s SPEEDSHIFT TCT 9G nine-speed automatic transmission. The torque-converter gearbox combines rapid gear changes with a more relaxed shifting character when the selected drive program calls for it.
Depending on the AMG DYNAMIC SELECT setting, the transmission can deliver sharp, sporty shifts or exceptionally smooth gear changes. It can also execute multiple downshifts in quick succession, allowing the engine to reach its most effective rev range almost immediately.
The Launch Control system has been specifically adapted to the rear-wheel-drive layout. Mercedes-AMG quotes a 0–200 km/h acceleration time of 11.4 seconds, while top speed is limited to 310 km/h.
Those figures are impressive, but the more revealing detail is the drivetrain layout: this is a car designed to make its performance accessible through driver inputs rather than relying exclusively on maximum traction.
A Racing-Inspired Chassis Developed with KW Automotive
The suspension is one of the defining features of the CLE 646 Spezialanfertigung. Mercedes-AMG worked with KW automotive to develop a steel coilover suspension system that can be precisely tuned for different driving styles, circuits and road conditions.
At its core is four-way adjustable damper technology, with independently configurable:
Low-speed rebound.
Low-speed compression.
High-speed rebound.
High-speed compression.
The low-speed settings influence body movements during braking, acceleration and turn-in. Their performance-focused calibration is intended to deliver sharper handling, improved driver feedback and greater stability.
The high-speed settings address rapid wheel movements caused by bumps, kerbs and surface irregularities. This allows the dampers to maintain control without compromising the car’s ability to absorb demanding road inputs.
The objective is not simply a stiff ride. It is a chassis that can be tuned to provide direct feedback, strong body control, traction and confidence when the car is operating close to its limits.
Ceramic Brakes Designed for Racetrack Abuse
The braking system has been engineered for sustained high loads. The AMG Ceramic High-Performance Composite Braking System includes a dedicated brake-cooling concept developed specifically for the CLE 646 Spezialanfertigung.
Large air intakes in the front bumper and airflow-guiding elements improve heat dissipation. At the front axle, 420 x 40 mm internally ventilated and perforated ceramic discs are paired with six-piston fixed calipers. The rear axle uses 360 x 32 mm ceramic discs with single-piston floating calipers.
The front discs feature long-fiber technology designed to transfer heat more rapidly from the friction surface into the cooling channels. This helps reduce brake-pad temperatures during demanding braking.
Ceramic construction also reduces weight and unsprung mass compared with a conventional braking system. That benefits more than stopping performance: lower unsprung mass can improve wheel control, turn-in response and the suspension’s ability to follow the road.
The gold-painted calipers provide a visual reminder that this is a braking system designed for extreme performance.
A Body 60 Millimeters Wider at Both Axles
The CLE 646 Spezialanfertigung’s proportions are not merely dramatic for the sake of appearance. Its bodywork has been extensively modified to support the car’s performance objectives.
The bodyshell has been reinforced and widened, increasing vehicle width by 60 millimeters at both the front and rear. The wider stance improves stability and cornering potential while creating the space required for exceptionally wide wheels and tires.
Carbon fiber is used extensively throughout the exterior, including:
Widened front fenders with integrated air outlets.
A redesigned front apron with large cooling intakes.
Side sill panels.
A bonnet with a central cold-air intake.
The roof.
The rear apron and diffuser.
A reinforced boot lid.
A manually adjustable rear wing.
The rear side windows and rear window are made from polycarbonate, while a lighter 12-volt starter battery contributes to the overall weight reduction.
The body structure also includes additional reinforcements and an integrated roll-over bar. These measures increase torsional rigidity, providing the foundation for precise suspension tuning and consistent driver feedback under high loads.
20-Inch Wheels with Tires Developed from AMG ONE Technology
They are fitted with exceptionally wide tires measuring 305/30 ZR20 at the front and 335/30 ZR20 at the rear. The tires are based on a further development of technology originally created for the Mercedes-AMG ONE.
Their design remains exclusive to the CLE 646 Spezialanfertigung, reinforcing the car’s position as a limited-production performance flagship rather than a conventional CLE variant.
The suspension also lowers the car by 22 millimeters at the front axle and 16 millimeters at the rear, giving it a lower center of gravity and a more purposeful stance.
A Two-Tone Finish for a One-Off Presence
The exterior design is finished in a distinctive two-tone combination. The front section is painted Mojave Silver Magno, while the bodywork from the B-pillar rearwards is finished in Obsidian Black Magno.
AMG crests on the driver’s and passenger’s doors emphasize the car’s bespoke character. The enormous grille, wide fenders and extensive exposed carbon-fiber elements give the CLE a far more aggressive presence than the standard coupé.
Yet the design is not simply about visual drama. Every major exterior modification serves a technical purpose, from cooling and wheelhouse ventilation to aerodynamic balance and downforce.
Aerodynamics: More Than 250 Kilograms of Downforce
The CLE 646 Spezialanfertigung’s aerodynamic package includes a front diffuser, fender louvers, underbody modifications and a manually adjustable rear wing.
The front diffuser can be adjusted between two positions using three fasteners:
Street: intended for road use.
Race: intended exclusively for racetrack operation.
In the Race position, the diffuser creates an inverted-wing profile beneath the front end. It accelerates airflow under the car and generates a Venturi effect, increasing front-axle downforce.
The benefits are intended to be felt through the steering wheel. Increased front-end load improves high-speed stability, turn-in response and steering precision when the car is subjected to high lateral forces.
The center section of the carbon-fiber rear wing can also be manually adjusted to increase rear-axle downforce and achieve the desired aerodynamic balance on a circuit.
Fender Louvers and Underbody Airflow
Open louvers in the widened front fenders improve wheelhouse ventilation while contributing to downforce. An airflow channel next to the headlights directs air through the wheel arches and out through the louvers.
Additional flics mounted on the sides of the front apron optimize airflow, increasing front-axle downforce while also supporting brake cooling.
The aerodynamic work continues beneath the vehicle. The front underbody remains almost fully enclosed, while longitudinal fins in the flat floor locally accelerate airflow and contribute to additional downforce.
Mercedes-AMG states that the complete system generates well over 250 kilograms of downforce at top speed.
That figure is particularly significant because it comes from an integrated package rather than a single large wing. The diffuser, underbody, wheelhouse ventilation and rear wing are designed to work together, balancing aerodynamic load across both axles.
Nine-Stage AMG TRACTION CONTROL
For closed-circuit driving with ESP switched off, the CLE 646 Spezialanfertigung features AMG TRACTION CONTROL, allowing the driver to select the level of rear-wheel slip support.
The system offers nine stages of adjustment, enabling the driver to tailor the car’s behavior to tire temperature, track conditions and personal preference.
At one end of the spectrum, the system can provide greater assistance in managing the engine’s considerable output. At the other, it allows experienced drivers to operate closer to the handling limit with reduced electronic intervention.
This is a feature that reinforces the car’s central philosophy: the driver should be able to determine how the car responds, rather than simply selecting a generic “Sport” or “Track” mode.
A Lightweight Interior with a Clear Purpose
The interior follows the same uncompromising approach as the exterior. AMG has removed the rear seats and acoustic insulation materials, reduced comfort equipment and simplified the sound system to save weight.
Several drive modes and assistance systems have also been deleted, allowing the number of controls on the AMG Performance steering wheel to be reduced.
The steering wheel itself is covered in DINAMICA microfiber and features a motorsport-inspired flattened shape designed to provide grip and control.
Ultra-lightweight racing bucket seats with pronounced lateral support are fitted as standard. A roll-over bar increases torsional rigidity, while lightweight carbon-fiber door panels complete the interior package.
The optional Performance Package adds six-point harnesses for the driver and passenger, further emphasizing the car’s circuit-focused character.
Hand-Built in Affalterbach
Every Mercedes-AMG CLE 646 Spezialanfertigung is hand-built in Affalterbach, based on a CLE 53 platform. The process continues AMG’s long tradition of exclusive manufactory craftsmanship, a tradition associated with iconic models such as the AMG 300 CE 6.0 “The Hammer.”
The extensive reconstruction is central to the car’s identity. This is not a vehicle that simply receives a power upgrade and a set of cosmetic changes on an assembly line. It is comprehensively rebuilt to meet the demands of its unique performance specification.
The Second Mercedes-Benz Mythos Series Model
The CLE 646 Spezialanfertigung is the second model in the Mercedes-Benz Mythos Series, a collection dedicated to exceptionally rare collector vehicles produced in strictly limited numbers.
It follows the Mercedes-AMG PureSpeed, which is limited to 250 examples worldwide and features an open two-seat configuration without a roof or windscreen.
The CLE 646 Spezialanfertigung takes a different approach. It remains a road-legal coupé, but its engineering is directed toward uncompromising racetrack performance.
The result is a vehicle that combines a distinctive appearance, extreme performance and an unusually direct driving experience. With only 30 examples planned and the entire production run already sold out before its world premiere, it is also destined to become one of the rarest modern AMG models.
Verdict: A Road-Legal AMG Built Around the Driver
The Mercedes-AMG CLE 646 Spezialanfertigung is best understood as a purpose-built performance machine wearing the shape of a luxury coupé.
Its 646-hp V8, rear-wheel-drive layout, four-way adjustable suspension, ceramic brakes, carbon-fiber bodywork and sophisticated aerodynamic package are not isolated upgrades. They are parts of a single concept designed to make the car more precise, more responsive and more involving.
At a time when high-performance cars increasingly rely on all-wheel drive, complex electronic systems and additional weight to deliver speed, the CLE 646 Spezialanfertigung takes a more focused approach. It removes weight, narrows the gap between driver and machine, and gives the rear axle a central role in the driving experience.
The result is an exceptionally rare AMG that promises to be as memorable for its engineering philosophy as it is for its performance figures.
Mercedes-AMG has opened orders for the all-new CLA 45 4MATIC+, bringing a new level of electric performance to the compact performance-car segment. With 680 horsepower, three axial-flux electric motors, an 800-volt electrical architecture and a claimed 0-100 km/h time of just 2.7 seconds, the new CLA 45 4MATIC+ is designed to combine supercar-like acceleration with the everyday usability of a premium compact sedan.
The latest AMG model also recently established a segment record on the Nürburgring Nordschleife, underlining Mercedes-AMG’s focus on combining outright electric power with sophisticated chassis and aerodynamic technology.
At the heart of the new Mercedes-AMG CLA 45 4MATIC+ is a three-motor electric powertrain producing a system output of 500 kW, equivalent to 680 hp. Mercedes-AMG quotes maximum system torque of 1,759 Nm, while the independent electric motors give the all-wheel-drive system a level of torque-control flexibility that would be difficult to achieve with a conventional mechanical drivetrain.
The CLA 45 4MATIC+ is available to order through Mercedes-Benz sales partners and online.
Mercedes-AMG CLA 45 4MATIC+ combines 680 hp with three electric motors
The headline figures immediately establish the CLA 45 4MATIC+ as one of the most powerful compact performance EVs on the market.
Its powertrain uses three completely independent axial-flux electric motors. Unlike conventional radial-flux motors, axial-flux technology can deliver exceptionally high power density while maintaining a compact and lightweight design.
The three-motor arrangement is particularly important because it allows Mercedes-AMG to control the distribution of electric torque with considerable precision.
Torque can be varied between the front and rear axles, while the two rear motors can independently distribute torque between the left and right rear wheels. This creates what AMG calls a fully variable Performance 4MATIC+ all-wheel-drive system.
The result is not simply more traction. The system is designed to actively influence the car’s handling characteristics depending on driving conditions, throttle input and the selected drive mode.
0-100 km/h in 2.7 seconds
With 500 kW and all-wheel drive, the Mercedes-AMG CLA 45 4MATIC+ is capable of accelerating from 0 to 100 km/h in a claimed 2.7 seconds.
That figure puts the compact AMG in territory traditionally occupied by much larger and significantly more expensive performance cars.
The instant torque delivery of electric motors is only part of the equation. The three-motor architecture allows the CLA 45 to continuously optimize torque distribution, helping maximize traction during hard acceleration and allowing the car to remain composed when the driver pushes beyond straight-line performance.
For AMG, however, acceleration is only one part of the equation. The CLA 45 4MATIC+ has been engineered around the goal of delivering genuine driver involvement rather than simply impressive acceleration numbers.
800-volt architecture targets both performance and charging speed
The new CLA 45 4MATIC+ also benefits from an 800-volt electrical architecture.
High-voltage electrical systems can support faster charging and help reduce the electrical losses associated with transferring large amounts of energy. In the CLA 45, the architecture works together with the high-power-density axial-flux motors to create an EV designed for both performance and long-distance usability.
Mercedes-AMG quotes a charging time of approximately 22 minutes for a 10-to-80-percent battery charge when using a suitable DC fast-charging station.
That is particularly significant for a performance vehicle that could otherwise demand frequent charging stops during long-distance driving.
More than 670 kilometers of range
Despite its performance focus, the new Mercedes-AMG CLA 45 4MATIC+ is not intended to be a short-range track special.
Mercedes-AMG quotes a range of more than 670 kilometers for the saloon, according to the applicable test procedure.
That combination of range and performance could make the CLA 45 an unusually versatile proposition. Drivers can exploit its 680-hp powertrain when conditions allow, while the aerodynamic systems and high-voltage architecture are designed to improve efficiency during normal driving.
The key challenge for AMG was therefore not simply extracting maximum power from the battery. It was creating an electric performance car capable of switching between efficiency and outright performance without compromising either objective.
One of the most technically interesting elements of the CLA 45 4MATIC+ is its all-wheel-drive system.
Traditional all-wheel-drive systems often rely on a mechanical connection between axles or electronically controlled clutches to vary torque distribution. The AMG system takes a different approach by using three independent electric motors.
Torque can be distributed continuously between the front and rear axles. At the rear, the two motors can also vary torque individually between the wheels.
This torque-vectoring capability can help the CLA 45 rotate into corners, improve traction when exiting a bend and maintain stability when the driver approaches the car’s limits.
In other words, the electric powertrain becomes an integral part of the chassis rather than simply a source of propulsion.
AMG RIDE CONTROL suspension gets serious upgrades
The chassis of the Mercedes-AMG CLA 45 4MATIC+ has also received extensive development.
The car uses a steel-sprung AMG RIDE CONTROL suspension system with adaptive three-way adjustable damping. AMG says the wheel-guiding components, springs and dampers have been fundamentally revised.
The objective is to increase maximum lateral acceleration while maintaining predictable and approachable handling at the limit.
That distinction matters. A performance car that generates impressive numbers but becomes difficult to read near its limits can be frustrating for experienced drivers. AMG’s approach with the CLA 45 is instead aimed at creating a car that communicates what its tires and chassis are doing as the pace increases.
The adaptive damping system also allows the suspension characteristics to be adjusted according to the selected driving mode and road conditions, giving the CLA 45 a wider operating range than a purely track-focused setup.
Active rear spoiler adds another layer of aerodynamic control
Aerodynamics play a major role in the CLA 45 4MATIC+’s performance strategy.
The saloon features a segment-first active rear spoiler, while the Shooting Brake receives an active roof spoiler. Both systems are designed to adjust the car’s aerodynamic balance depending on the selected driving program or driver input.
At lower aerodynamic loads, the spoiler can adopt a position intended to reduce drag and maximize efficiency. When greater stability is required, it can change angle to generate additional downforce.
This is an increasingly important feature on high-performance EVs. Electric cars have to balance two competing demands: minimizing aerodynamic resistance to maximize range and generating aerodynamic stability at high speeds.
The active spoiler allows the CLA 45 to address both requirements rather than permanently optimizing the car for one or the other.
Active grille shutters improve aerodynamic efficiency
The CLA 45’s aerodynamic package also includes advanced active front grille shutters.
At high speeds, the shutters remain closed to reduce aerodynamic drag. They open when the vehicle requires additional cooling airflow.
It is a relatively simple concept, but one that becomes increasingly valuable as manufacturers attempt to maximize EV efficiency without compromising thermal management.
For the CLA 45, aerodynamic efficiency is therefore not merely a styling exercise. The active systems are integrated into the vehicle’s broader performance strategy, helping the car transition between maximum range and maximum high-speed stability.
Nürburgring development shows AMG’s priorities
The new CLA 45 4MATIC+ recently demonstrated its performance credentials by setting a segment record on the Nürburgring Nordschleife.
The legendary 20.8-kilometer circuit is one of the toughest development environments in the automotive world, combining high-speed sections, elevation changes, heavy braking zones and challenging corners.
A Nürburgring record does not automatically make a car the best everyday performance vehicle, but it does provide an indication of how seriously AMG has approached the CLA 45’s chassis, powertrain and aerodynamic development.
The three-motor powertrain, torque vectoring, adaptive damping and active aerodynamics are clearly designed to work as one integrated system.
Mercedes-AMG CLA 45 4MATIC+ brings supercar acceleration to the compact class
The all-new Mercedes-AMG CLA 45 4MATIC+ represents a significant evolution of AMG’s approach to electric performance.
Its 680-hp output and 2.7-second 0-100 km/h acceleration time are the numbers that will attract the most attention, but the more important story lies beneath them.
Three axial-flux motors provide independent control of the front and rear axles and individual rear wheels. An 800-volt architecture supports rapid charging. Adaptive three-way damping gives the chassis a broader range of capabilities, while active aerodynamic elements allow the car to prioritize either efficiency or stability.
With more than 670 kilometers of claimed range for the saloon and a 10-to-80-percent DC fast-charging time of around 22 minutes, the CLA 45 is also attempting to eliminate one of the traditional compromises associated with high-performance electric cars.
Mercedes-AMG has therefore taken a different route with the new CLA 45 4MATIC+: rather than building an EV that is simply extremely fast in a straight line, it has developed a compact performance car in which the electric powertrain, chassis and aerodynamics are all designed to work together.
If the Nürburgring performance is any indication, the new CLA 45 4MATIC+ could become one of the most technically sophisticated electric AMG models yet—and a serious benchmark for the next generation of compact performance EVs.
