The upcoming Mercedes-AMG GT will be powered by a twin-turbocharged four-valve-per-cylinder 4.0-litre V8 petrol engine, the German car maker has officially confirmed.
In its initial state of tune, the unit will develop 503bhp at 6250rpm and 479lb ft of torque on a band of revs between 1750 and 4750rpm.
The all-new 90-degree quad-cam direct-injection unit, known internally under the codename M178, has been developed from the ground up as a replacement for AMG’s existing naturally aspirated 6.2-litre V8, the M159, which is being phased out after four years, following the end of production of the SLS AMG in both coupé and roadster guises.
