Mercedes’ AMG division unveils new twin-turbo V8

Those obsessed with torque bemoaned Mercedes’ high-revving 6.2-litre V8 when it was launched in 2005, but just as the world has come to accept the naturally aspirated engine, the company has now unveiled a new twin-turbo 5.5-litre V8. Up to 563bhp – which is the same as the SLS AMG – and 663lb ft, which is much more than the 479lb ft the modern-day Gullwing supercar manages. The engine is an all-new 5.5-litre V8 (5461cc to be exact) with direct-injection technology, an aluminium crankcase and two turbochargers.
