Mercedes-AMG CLA 45 Debuts at Goodwood with 680 HP and Axial-Flux Power

A New Era for AMG Performance

The legendary grounds of the Goodwood Festival of Speed have long served as a theater for automotive excellence, but this weekend, the spotlight belonged to the future of electric performance. Mercedes-AMG officially pulled the curtains back on the new CLA 45 4MATIC+, a vehicle that marks a seismic shift for the high-performance division. With a staggering 680 horsepower and an advanced tri-motor configuration, the CLA 45 is not merely an electric car; it is a declaration of intent from Stuttgart.

The debut was punctuated by the presence of Kimi Antonelli, the rising Formula 1 star who piloted the vehicle up the iconic hill climb. His involvement signals the brand’s desire to bridge the gap between its track-dominating hybrid F1 cars and the consumer-facing electric vehicles hitting the streets by 2026.

Engineering the Electric Beast

At the heart of the new CLA 45 lies a sophisticated powertrain architecture that sets it apart from typical battery-electric vehicles. The standout feature is the integration of three axial-flux electric motors. Unlike the traditional radial-flux motors found in the vast majority of EVs, axial-flux motors offer a significantly higher power density and a more compact form factor.

This technology allows for a lighter weight distribution and greater thermal efficiency, which is vital when pushing 680 horsepower through all four wheels. The 4MATIC+ all-wheel-drive system has been recalibrated specifically for the instant torque characteristics of electric motors, ensuring that the car can translate its immense output into usable grip, whether exiting a hairpin turn or accelerating on a straightaway.

Key Technical Specifications

• Total Output: 680 horsepower (500 kW)
• Motor Configuration: Three axial-flux motors (one front, two rear)
• Drivetrain: Fully variable 4MATIC+ all-wheel drive
• Heritage: Inspired by F1-grade energy management systems
• Design Language: Aerodynamically optimized for high-speed stability

Performance Meets Precision

During the Goodwood demonstration, the CLA 45 showcased the kind of aggressive acceleration that has defined the 'AMG' badge for decades. While the soundscape has changed from the roar of a handcrafted V8 to the high-pitched whine of electric motors, the sensation of speed remains visceral. The three-motor setup allows for advanced torque vectoring, meaning the car can independently adjust the power sent to each rear wheel. This creates a level of agility that would be impossible to achieve with a traditional internal combustion engine setup.

Mercedes engineers noted that the transition to electric power has allowed them to rethink how weight is managed. By placing the heavy battery pack low in the chassis and utilizing the compact nature of axial-flux motors, the center of gravity is significantly lower than the previous generation of CLA models. This results in sharper turn-in and reduced body roll during high-speed cornering.

The Role of Kimi Antonelli

Having Kimi Antonelli behind the wheel was a strategic masterstroke by Mercedes. As the young prospect continues to climb the ranks toward a potential F1 seat, his association with the brand’s most powerful electric production car serves as a bridge for younger enthusiasts. Antonelli noted that the car’s response time is unlike anything he has experienced in traditional machinery, emphasizing that the instant nature of the torque makes it a formidable machine on technical circuits.

Looking Toward the Future

The Mercedes-AMG CLA 45 is more than just a headline-grabbing vehicle; it represents the blueprint for the next decade of performance motoring. As regulations tighten and the industry moves toward complete electrification, AMG is proving that the soul of a performance car does not have to be lost in the switch to batteries. By focusing on axial-flux technology and intelligent power distribution, the brand is ensuring that the 'AMG' name continues to command respect on both the track and the road. With the global market watching, the CLA 45 is set to become the benchmark for electric performance sedans when it officially rolls into showrooms.
