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.

Concept Car of the Week: Bertone Lamborghini Genesis (1988)

After its beginnings as a tractor manufacturer, Lamborghini quickly became synonymous with exciting supercars and luxurious gran turismos and it's remained so ever since. Bertone was responsible for the design of its finest cars including the Miura, Countach and Marzal concept amongst many others. However along the way there have been a few quirks in this otherwise thoroughbred bloodline – remember the weapons-grade LM002 SUV?

Ford Focus RS500 (2010) first official pictures

This is the new Ford Focus RS500, a special limited edition version of the Blue Oval’s mad Focus RS hot hatch with 15% more power. For a start there’s that extra power. Thanks to a larger air-to-air intercooler, a bigger air filter and a wider diameter exhaust downpipe (plus a new ECU to take advantage of the mechanical changes) peak power is up from 301bhp to 345lb ft at 6000rpm, while torque climbs from 325lb ft to 339lb ft. The result is a 5.6sec 0-62mph time (down three-tenths) while the top speed climbs two notches to 165mph.
