Mercedes-Benz is continuing its unrelenting marketing campaign for the upcoming 2015 Mercedes-AMG GT and in the latest video, AMG CEO Tobias Moers claims that the upcoming sports car will provide some true thrills.
As a matter of fact, he calls the impending car “a beast” complete with “insane acceleration, massive power and tremendously high torque.”
When fitted to the range-topping Mercedes-AMG GT-S, the 4.0-litre biturbo V8 engine delivers an impressive 503 hp at 6250 rpm. That equates to 126 hp per litre and is joined by an equally impressive torque figure of 479 lb-ft between 1750 and 4750 rpm.
Known internally as the M178, the engine is a completely new replacement for the naturally-aspirated 6.2-litre V8 engine which of course powers the GT’s predecessor, the SLS AMG. The new engine is pinned to power the next-generation Mercedes-Benz C63 AMG as well.
It features the same 83 mm bore and 92 mm stroke as the 2.0-litre turbocharged four-cylinder utilised by the A 45 AMG, CLA 45 AMG and GLA 45 AMG. The turbochargers are produced by Borg Warner and operate at a maximum pressure of 2.3 bar.
Some of the other cool features of this new powerplant is the Bosch piezo injection system which delivers up to seven injections per cycle. Elsewhere, the cylinder barrels are finished in the German marque’s Nanoslide material to dramatically reduce friction and improve efficiency.
