The company basically binned the car's stock high-output 2.0-liter biturbo-based hybrid powertrain—battery pack and all—and swapped in an older version of Mercedes-AMG's latest 4.0-liter twin-turbo V-8. That means, VUK's custom-made V-8 W206 C 63 S is the only one of its kind in the entire world.

Mercedes-AMG's new high-performance medium SUV is a very different beast, swapping the old V8 for a stonking four-cylinder plug-in hybrid.

Mercedes has joined the ranks of manufacturers putting the brakes on electric cars, even promising to bring back V8s in a bid to win back customers.

Based on the four-door variant of the AMG GT Coupe, the 63 S E Performance is the top-of-the-line model sporting all the bells and whistles, including the company's renowned 4.0-liter bi-turbo V-8. But it doesn't produce power alone as its insane performance numbers happen thanks to AMG's latest F1-derived electric hybrid-drive system.

Yep, you read that correctly. Mercedes-AMG confirmed it is working to develop a new hybrid V-8 powertrain that should arrive as soon as 2026.
