For months we speculated about the all-new AMG GT, and after a round of official photos and the release of an official video, we no longer have to speculate. The upcoming Mercedes-Benz AMG GT sports car will use a new twin-turbocharged 4.0-liter V-8 engine with a mill that uses up to 17.4 psi of turbo boost. The engine is capable of 510 hp at 6250 rpm, and 479 lb-ft of torque between 1750 and 4750 rpm.
Dubbed the M178, the Mercedes-Benz AMG GT engine is related to the other new twin-turbo V-8 engines within the Mercedes family. The M178 engine, however, has received multiple high-performance changes that have made it ideal for the AMG GT. Dry-sump oiling negates the need for an oil pan, allowing the engine to sit 2.2 inches lower in the car’s chassis. Forged pistons add strength, while a special “nano slide” coating within the cylinders reduce friction against the pistons. There are also turbochargers located inside the engine block, with a pair of intercoolers sited ahead of the V-8.
The video below comes directly from Mercedes, as do the photos.
