Porsche 911 GT2 RS (2010) first official pictures

You’re looking at the new Porsche 911 GT2 RS, not just the most powerful 911 that Porsche has ever built, but the company's most powerful road car period. The output from the GT2 RS’s twin-turbo flat six? 611bhp – 88bhp more than before. And as the new GT2 RS – there will be no ‘regular’ GT2 version – weighs 70kg less than its predecessor, that wholesome 611bhp provides this rear-engined monster will a stunning 446bhp/tonne.

2014 Porsche Panamera V6 Diesel Facelift gets more power

The 2014 Porsche Panamera V6 Diesel Facelift (pictured) gets more power When Porsche revealed the facelift for the Panamera in April, we commented that we could expect a new V6 diesel to arrive in the Panamera for 2014 with around 300bhp. And here it is. The new Porsche Panamera V6 diesel gets the same tweaks to bumpers and lights as the rest of the range – and modest though they are, they do make the Panamera look a little less bulbous – but the most appealing news is a bit more oomph from Porsche’s entry-level diesel Panamera.

BMW 335iS (2011) prices +video

The BMW 335iS Convertible - starts at $59K Normally we would have made the headline ‘BMW 355iS US prices’, but as BMW has decided that the new 335iS is going to be a North America car only we guess that anyone looking for a price will know it’s going to be a dollar price. As we reported last week, BMW are releasing the 335iS to bridge a gap they perceive exists between the 335i and the M3. Which seems more like the sort of think Audi would do rather than BMW, but perhaps they’ve learnt a trick or two from their four-ringed neighbours about filling every possible niche?
