New Porsche 911 GT3 (991) technical highlights (video)

Ahead of its arrival with customers, Porsche has delivered a new video of the GT3 designed to make it clear just how some of its technical highlights work to make the GT3 swifter and more nimble than ever before. Power is of course the key to the GT3 – 468bhp and 324lb/ft of torque – but the power is no good unless the GT3 can put that power down as efficiently as possible in all circumstances. Porsche assert that the GT3′s chassis is engineered for Motorsport, and key elements of the new GT3 make it even more able.

New Aston Martin V12 Vantage S quicker than Jaguar F-Type V8 S

The new Aston Martin V12 Vantage S (pictured) is Aston’s quickest car At the end of last month, as expected, and following the ending of production of the V12 Vantage, the new Aston Martin V12 Vantage S arrived. Aston proclaimed the new V12 Vantage S as the quickest production car they’d ever built (with the exception of the £1 million One-77) but declined to tell us exactly how quick it was. But now AML have finished playing with their stopwatch and declared the V12 Vantage S will get to 62mph in 3.9 seconds (0-60mph in 3.7s), an improvement of 0.3 seconds on the V12 Vantage and giving the V12 Vantage S the edge over the car we think it should be compared to – the new Jaguar F-Type V8 S.

EPA makes it official--greenhouse gases are pollutants

On the eve of an international climate summit, the EPA on Monday formally declared greenhouse gases to be dangerous pollutants, strengthening President Barack Obama's hand and laying the groundwork for a new 35.5 mpg standard for light vehicles. The finding is likely to have a greater impact on electric utilities, oil companies and manufacturers than on the auto industry. The EPA's scientific finding reported that these gases “are the primary driver of climate change,” which can intensify heat waves and increase ozone pollution linked to asthma and other respiratory illnesses.
