Mercedes’ new twin-turbocharged 4.0-litre V8 will produce just as much torque as the 6.2L V8 it will replace despite being 35 per cent smaller in capacity.
The German luxury car maker says the new engine destined for the new Mercedes-AMG GT sports car and next-generation C63 AMG will produce up to 650Nm of torque, matching the output of the naturally aspirated 6.2L V8 in the soon-to-be-superseded SLS AMG supercar.
The engine will also produce up to 375kW of power at 6250rpm, which leaves it 45kW short of the larger engine but up on the 373kW/610Nm 6.2-litre V8 used to power the current C63 AMG Edition 507 performance flagship and well clear of the regular C63’s 336kW/600Nm output.
The all-new V8 engine, codenamed M178, features a dry-sump lubrication system that Mercedes says allows the engine to sit 55mm closer to the ground, lowering its centre of gravity.
The turbochargers are also positioned inside the engine block between the cylinder banks to keep the unit as compact as possible.
The powertrain details come just days after camouflaged images of the Mercedes-AMG GT coupe appeared in AMG’s Driving Performance magazine.
The GT will be smaller, lighter and significantly more affordable than the circa-$470,000 SLS, with pricing tipped to align it more closely with the $200,000-plus Porsche 911.
Mercedes teased the new engine’s distinctive rumble in one of a series of teasers late last month, following the release of images of its driver-focused interior earlier this year.
The Mercedes-AMG GT has been rumoured to make its debut at next month’s German Grand Prix before reaching global showrooms, including Australia, early next year.
The new Mercedes-Benz C63 AMG will break cover at October’s Paris motor show before reaching our shores around mid-2015.
