Previous generations went head-to-head with models such as the Audi RS 3, but the new Mercedes-AMG CLA 45 moves into a different class altogether, thanks to a major leap in power and performance. Pricing for the EU has not yet been confirmed, but it is expected to start at around €75,000, broadly in line with its predecessor.
The biggest change is beneath the surface. For the first time, Mercedes-AMG has fitted the CLA 45 with a fully electric powertrain. Even by today's EV standards, its 671bhp output is impressive for a car of this size.
Performance figures are equally impressive.
The new CLA 45 sprints from 0–100 km/h in just 2.7 seconds, placing it firmly in hypercar territory. That is not far off cars such as the Ferrari LaFerrari and Aston Martin Valkyrie, while also matching modern hybrid all-wheel-drive supercars including the Ferrari SF90 and Lamborghini Revuelto.
AMG achieves this performance using technology derived from the significantly more expensive AMG GT 4-Door. The CLA uses three axial-flux electric motors developed in partnership with Yasa, a specialist electric motor manufacturer.
To retain some of the traditional AMG driving feel, Mercedes-AMG has added simulated engine sounds and virtual gear shifts controlled via steering-wheel paddles. Rather than creating an artificial futuristic soundtrack, AMG says the system recreates the character of its previous turbocharged four-cylinder engine, including the familiar pops and crackles associated with performance exhaust systems.
The headline 671bhp figure is available in Overboost mode, while continuous output stands at 603bhp — matching the power of the previous-generation Mercedes-AMG E 63 S. Torque reaches an extraordinary 1,759Nm, while top speed is electronically limited to 250 km/h, rising to 285 km/h with the optional AMG Driver's Package.
Power comes from a 94kWh battery developed specifically for AMG applications. Compared with the standard electric CLA, capacity has increased by 9kWh, while maximum DC charging rises to 330kW. Under ideal conditions, the battery can be charged from 10% to 80% in approximately 22 minutes.
Mercedes-AMG estimates a driving range of more than 665 km for the saloon and around 637 km for the slightly less aerodynamic Shooting Brake. Those figures are especially impressive given the car's performance, although the CLA 45 remains a substantial vehicle, weighing close to 2.3 tonnes.
Aerodynamics have also received serious attention. Both body styles feature an active rear spoiler that sits flush with the body during normal driving before automatically deploying at higher speeds to improve stability.
Elsewhere, the styling changes over the standard CLA are relatively restrained. Larger wheels, revised front and rear bumpers and subtle aerodynamic tweaks give the car a more aggressive look without dramatically altering its overall design.
A closer look reveals wider front wheel arches and the removal of the full-width front light bar, bringing the CLA 45 more closely in line with the AMG GT 4-Door. The illuminated grille design has also been replaced by AMG's traditional Panamericana vertical slats.
Inside, the cabin gains several AMG-specific upgrades, including new performance bucket seats and exclusive graphics for the three digital displays across the dashboard.
The latest AMG steering wheel also makes its debut, featuring dedicated drive mode controls and rotary selectors integrated into the upper spokes.
