2013 Aston Martin DB9 – Virage Vanquished

Aston Martin has given the DB9 a makeover – a facelift and a bit more – for 2013 as the tweaked DB9 signals the end of the Virage. But all is not lost with the Virage, as the 2013 DB9 gets a Virage makeover – inside and out as well as more power from its V12 and the addition of Aston Martin’s adaptive damping. The 5.9 litre V12 engine under the new DB9′s bonnet now offers 510bhp and 442lb/ft of torque – more than the Virage managed to muster – and is much the same as the revised AM11 V12 we see in the new Vanquish but with a bit less power.

Bentley has codeveloped the new V8 with Audi.

Mercedes AMG GT gets new 503 bhp Twin-Turbo 4.0 litre V8 (video)

The new Mercedes AMG GT (pictured) gets the new 503 bhp Twin-Turbo 4.0 litre V8 We’ve speculated that the new Mercedes AMG GT – and, for that matter, futures ’63′ AMGs – will get a new twin-turbo V8 to provide the power as Mercedes look to move away from the naturally aspirated 6.2 litre V8 in cars like the SLS. And this is it. A new 4.0 litre twin-turbo V8 – the M178 engine – has been developed to replace the 6.2 litre V8 and, in initial tune, develops 503 bhp at 6250 rpm and 479lb/ft of torque from just 1750 rpm.
