" The W204 C63 AMG comes stock with the now officially gone M156 6.2 liter naturally aspirated V8
. In the new 63 AMG models Mercedes introduced the 5.5 liter twin turbo and direct injected M157 motor. Well, German tuner GAD-Motors had the brilliant idea of swapping the new M157 V8 into the W204 C63 AMG chassis which unlike its 63 AMG siblings never was updated to the newer twin turbocharged powerplant. As the race against the 911 Turbo shows, the result is a car with devastating performance.
GAD-Motors pulled off the swap and for icing the cake paired it to a 4MAtic AMG powertrain. They also gave it upgraded turbochargers. Yes, this is a twin turbo V8 all wheel drive C-Class. Essentially it mimics the E63 AMG S although with less weight due to being based on the C63 AMG Black Series
. The result is a car that moves very well as is shown in the video below against a stock 991 Turbo S which itself is no slouch
. The 10 second 911 Turbo just gets demolished.
All this does though is make BenzBoost yearn for an M157 V8 paired to a lighter chassis. This does highlight the problem for Mercedes-AMG though as a C-Class with the M157 is just going to annihilate everything else in the lineup at least in a straightline. Apparently Mercedes had enough of C63 AMG owners tuning their cars making them much faster than the other 63 AMG's in the lineup with software alone.
Enjoy the race video although like most race videos from the Middle East the video quality is incredibly poor for whatever reason. Expensive top notch cars yet cheap low end video equipment, you make sense of it. "
