Mercedes' Wolff says Hamilton Rosberg rivalry won't boil over

MERCEDES motorsport boss Toto Wolff is confident the simmering rivalry between Lewis Hamilton and Nico Rosberg will not boil over and has revealed the pair may be allowed to duel for the Formula One title. German Rosberg leads the drivers' standings on 202 points, with Briton Hamilton 11 points behind and their nearest rival Daniel Ricciardo (Red Bull) a further 60 points adrift. Mercedes have won nine of the 11 grands prix this season and it appears Rosberg and Hamilton, whose relationship has been frosty of late, are in pole position for the title.

Bentley teases new model: hear the new V8 in action

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.

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.
