Mercedes unveils powerful new AMG 4.0-litre twin-turbo V8

By John Mahoney Motor Industry 25 July 2014 17:09 Mercedes AMG has released details of an all-new 503bhp 4.0-litre twin-turbo V8 that will help fill the void when the production of its normally aspirated 6.2-litre V8 ends.

The first car to receive the new engine will be the Porsche 911-rivalling Mercedes AMG GT, but other smaller cars like the C63 AMG are also set to benefit from its compact design.
