As most of you know, the AMG GT will be powered by at least three versions of an all-new V8 engine, created by combining two M133 four-cylinders from the A 45, CLA 45 and GLA 45 AMG.
With a displacement of four liters and internally codenamed M178, the new twin-turbocharged V8 uses twin-scroll turbochargers that sit inside the cylinder lines, just like in the BMW S63 and the Audi 4.0 TFSI engines.
The combination between direct injection, twin-scroll turbochargers and the reversal of the intake with the exhaust manifold is apparently improving the engine response to such a level that it drastically minimizes lag.
Insiders say that the M178 will have a throttle response not unlike a naturally-aspirated engine, with no lag whatsoever, but that remains to be seen when the car is actually launched.
Since the AMG GT is using a reworked aluminium spaceframe borrowed from the SLS AMG, it will have a similar positioning of the powertrain. In other words, it will be a front-mid engine with a transaxle dual-clutch transmission.
Expect more information about the upcoming sports car in the next couple of months, as it nears is projected September unveil and October launch, most likely at the 2014 edition of the Paris Motor show. Meanwhile, have a look at it torturing tires on the Nordschleife.
