Mercedes-Benz has disclosed full details about the engine which will power the upcoming AMG GT.
It turns out previous rumors were spot on as the AMG GT will feature a twin-turbo V8 4.0-liter engine delivering 510 PS (375 kW) at 6,250 rpm and a maximum torque of 650 Nm (479 lb-ft) between 1,750 rpm and 4,750 rpm.
Codenamed M178, this Euro 6-compliant engine has a dry weight of 209 kg (460 lbs) and benefits from lightweight pistons and twin overhead camshafts while the flow-optimized cylinder heads feature zirconium alloy for optimal temperature and thermal conductivity. The cylinder walls have been lined with a nano-slide coating in order to diminish friction losses and there's no need for a conventional oil pan as the engineers used a dry sump lubrication technology.
The same engine will also find its way under the hood of the upcoming C63 AMG models (sedan, estate, coupe and cabriolet) but we will see it first on the AMG GT set to be unveiled this fall before going on sale March 2015.
