Mercedes revealed the next-generation AMG CLA 45 4MATIC+ at Goodwood Festival of Speed, armed with 680 horsepower and three axial-flux motors that represent a significant leap in the brand's performance electric strategy. The new sedan pairs a front-mounted motor with dual rear axial-flux motors, a configuration that enables aggressive torque distribution and rapid acceleration across all four wheels.
Axial-flux motors differ fundamentally from traditional radial designs. They're thinner, more efficient, and pack more power density into compact spaces. Mercedes engineered this architecture to deliver the performance credentials expected from the AMG nameplate while maintaining the platform flexibility required for a compact sedan. The 680 hp output positions the CLA 45 as a direct competitor to the BMW M440xDrive and Audi S4, both of which operate in the 500-550 hp range.
This powertrain arrangement provides advantages beyond raw numbers. The dual rear motors enable torque vectoring, where power distribution shifts between wheels to enhance cornering precision and stability. The front motor complements this system, creating a three-point architecture that improves weight distribution compared to conventional dual-motor EVs.
Mercedes chose Goodwood as the stage for this reveal deliberately. Rising Formula 1 driver Kimi Antonelli piloted the vehicle through the famous hill climb, signaling the brand's commitment to authentic performance credentials. The choice of Antonelli also underscores Mercedes' pipeline strategy for driver talent and brand ambassadors.
The CLA 45 segment occupies critical market real estate for luxury brands. Compact high-performance sedans appeal to younger buyers seeking accessible performance without full-size sedan commitments. Tesla and traditional manufacturers increasingly compete for this demographic, making drivetrain innovation essential. The three-motor architecture differentiates Mercedes from competitors relying on dual
