This Mercedes-AMG GT Doesn't Sound Like It Has a V-8

If you simply saw a picture of the Mercedes-AMG GT above, you'd probably assume it was the upcoming Black Series. Just look at its super-aggressive aerodynamic package. But watching video of this car testing at the Nürburgring casts doubt on that theory because it does not sound like it has a V-8.


The video comes to us from YouTuber CvdZijden, who captured this mysterious AMG GT during an Industry Pool test session at the 'Ring. They speculate that this GT has the M256 inline-six used in AMG's 53-series cars, and that certainly seems like a likely scenario. The sound is quite muted, almost like a four-cylinder, and you can hear a turbocharger blow-off valve quite prominently.

An AMG GT with the 53-series straight-six would make sense-it would likely lower the barrier of entry for the sports car from the $112,700 it sits at today. A 3.0-liter motor like this would be good for markets like China, where cars are taxed based on engine displacement.

It's a killer engine, too, with an electric motor on the crank that replaces the traditional starter and alternator and an electric compressor run off a 48-volt battery system. In the 53-series cars, it makes 429 horsepower, and 384 lb-ft of torque. Not massive numbers in the world of $100,000-plus sports cars, but the throttle response from the electric motor and compressor is extraordinary.

But what's puzzling is all these aero components on what could possibly be the entry-level version of the AMG GT. Note the big splitter with grille-mounted supports and dive planes ahead of the front wheels. It even looks like there's a dive plane at the back of the front fender, just ahead of the door. This prototype is also wearing the AMG GT R's "Green Hell Magno" paint, and it looks like it has a similar diffuser and wing, too.

It's a mystery. There's, of course, a possibility that this prototype is just a mashup of different things, and not representative of a car meant for public consumption. Perhaps AMG is working on both a V-8-powered Black Series with an aggressive aero package and an entry-level six-cylinder GT.
