Another electric AMG is creeping closer to production, and this time it’s literally raised its game. Fresh spy shots of the upcoming AMG C-Class EV have caught its pop-up rear spoiler deployed, giving us another clue about the car Mercedes hopes will keep the electric BMW M3 honest.

The regular electric C-Class debuted in April, but AMG’s version is still undergoing development ahead of an expected 2027 launch. Curiously, this latest prototype is actually more disguised than the one we saw in June, with additional camouflage obscuring the taillights and lower doors, suggesting its an older test car. But at least it forgot to hide the interesting bit.

Rising from the trunk lid is the active rear spoiler we’d previously suspected was lurking there. Sources say the AMG will use active aerodynamic hardware to genuinely key the fat tires into the road surface, so the wing isn’t simply an elaborate way of telling everyone you bought the expensive C-Class.

Elsewhere, this prototype wears different wheels from the last one we spied, while the production car is expected to get a more aggressive AMG body kit. Underneath, Mercedes is reportedly developing modified air suspension and rear-wheel steering, with AMG promising an “authentic experience” covering performance, handling and even sound.

Can fake sounds be authentic? The recently revealed electric CLA 45 uses synthesized combustion noises, simulated gearshifts and even active seat shakers to replace some of the sensations EVs normally delete. So we expect similar features in the electric AMG C-Class, and plenty of power to go with them.

778 HP Rumored

Mercedes hasn’t confirmed the specs of the AMG C-Class, but between what we already know about the CLA 45 and the C400 4MATIC Electric, and rumors coming out of Affalterbach, a Yasa tri-motor setup producing around 778 hp (789 PS / 580 kW) seems likely.

The hot C-Class will need serious muscle simply to outrank the CLA 45, which already produces up to 671 hp (680 PS / 500 kW) from its own three-motor powertrain. The standard C400 4MATIC Electric, meanwhile, has two motors and makes a more modest 482 hp (490 PS / 360 kW). The C400 also supports DC charging at up to 330 kW and can travel up to 473 miles (762 km) on a charge, though the AMG C-Class won’t match those figures if it retains the C400’s 94 kWh battery.

Ultimately, though, AMG’s biggest challenge won’t be beating its little brother. BMW is preparing its first electric M3, meaning two of Germany’s defining performance sedans are heading into the battery era at roughly the same time.
