More Power! Get the details on the potent Porsche 911 GT3 RS 4.0

Porsche has ramped up the already heady performance of the 911 GT3 RS through the adoption of a new, naturally aspirated 4.0-liter version of the company's sturdy, horizontally opposed flat six-cylinder engine. The unit kicks out 50 hp more than the 3.8-liter six-cylinder used in the existing 911 GT3 RS. This mill claims 500 hp at 8,250 rpm, a figure which makes the speedster the most powerful naturally aspirated road-going version of the 911 ever.

Porsche Panamera S E-Hybrid qualifies for £5,000 taxpayer incentive

Porsche Panamera S E-Hybrid qualifies for £5,000 taxpayer incentive When Porsche revealed the first facelift for the Panamera back in April, they also revealed the Panamera S E-Hybrid, a plug-in hybrid with the power of a V8 and the fuel consumption of a city car. It’s a brilliant demonstration of how car makers have worked their way round the daft CO2 tax regimes designed to strangle the marketplace for powerful, luxury cars by using technology to attain far lower official emissions figures than ever. In the case of the Panamera S E-Hybrid that means a plug-in hybrid with a 94bhp electric motor to boost the power from the 3.0 litre V6 to 410bhp.

I Draw Cars: The sketchbook that puts drawings into perspective

I Draw Cars is a project set up by Adam Hubers and Matt Marrocco – both CCS graduates – to encourage designers young and old to pick up their pens and practice that most basic yet powerful tool in their kit: sketching. Their new book features over 100 pages of perspective underlays – from basic views right up to complex three-point – to use as templates with which to practice. Each underlay is printed in non-photo blue, meaning it won't be picked up by a scanner should you choose to drop it into Photoshop.
