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. Lightweight, compact and more efficient than the big 6.2-litre it replaces, the new smaller capacity turbocharged V8 produces 479lb ft from just 1750rpm. 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.

French government vows Renault reform after meeting with Ghosn

The French state, which owns 15 percent of Renault, has called for a thorough investigation into discredited claims that three Renault executives were spying on the carmaker, possibly for a foreign government.
