BMW shows off first F30 335i racing machine

When one's thoughts get to meandering and said meanderings lead to Bavarian racing machines, BMW's M cars are often first to mind. But the first race car built on BMW's new F30 bones is actually a 335i. Given that the new car's stock turbo six cranks out power similar to that of the naturally aspirated screamer in the 2001-06 E46 M3, building a dedicated rennsport machine from a non-M 3-series doesn't seem like the great loss of opportunity it once could've been.

Renault Twin’Run gets 316bhp & pays homage to the Renault 5 Turbo

The Twin’Run is an extreme version of the next Twingo and manages to pay homage to the old Renault 5, with a thumping great V6 bolted in the middle and pumping out 316bhp and 280lb/ft of torque, enough to get to 62mph in 4.5 seconds and on to 155mph. The Nissan-sourced V6 gets mated to a SADEV six-speed sequential gearbox and comes with a limited slip diff to stop the tyres burning off when the going gets brisk. As well as endowing the Twin’Run with lots of power, Renault has also kept weight down to 950kg by using a tubular chassis, glass-polyester composite for the bodywork, lumps of carbon fibre and not a hugely laden interior.

Range Rover by Overfinch has 30% higher residuals than a standard Range Rover

The 2014 Overfinch Range Rover (pictured) keeps its value It’s generally considered that money you spend on enhancing a new car by getting one of the plethora of customisers to add interesting bits is money down the drain. But as we reported back in 2012, that’s definitely not the case with the Range Rover by Overfinch. In fact, the last model of the Range Rover had residuals a full 23 per cent more if it was an Overfinch version rather than a regular Range Rover, which made opting for an Overfinch makeover almost a no-brainer.
