Porsche reveals extreme 911 GT2 RS

Porsche has revealed its most powerful and arguably most extreme road-going 911 to date: the GT2 RS. The new rear-wheel-drive road rocket will debut publicly at the Moscow auto show in late August and will go on sale in the United States in October. The GT2 RS, to be built in a limited run of 500, is powered by the latest evolution of Zuffenhausen's 3.6-liter, twin-turbocharged, horizontally opposed six-cylinder engine, tuned to deliver a Le Mans-grade 620 hp.

E85 makes inroads on cost and availability

Three years ago, we embarked on a Midwest road trip in search of what was then the Holy Grail of fuel: E85. Our findings weren't too positive--there were far more E85-compatible vehicles on the road in 2006 (5 million) than there were E85 pumps to fuel them (about 700 out of some 200,000 fuel stations nationwide). In addition, those burning the mix of 15 percent gasoline and 85 percent ethanol were paying a pretty penny for their earth-friendly ways, losing about 15 percent in fuel economy while often paying the same price as for regular unleaded.

New Hyundai Test Centre at the Nurburgring revealed

Hyundai’s new test centre at the Nurburgring If anyone had said, just a few years ago, that Hyundai would develop a test centre at the Nurburgring to help shake-down their cars, they’d have been laughed at. But Hyundai – and Kia – have come so far in recent years that it makes absolute sense for them to develop a full-time testing facility at the Nurburgring to test their cars for the road, along with just about every other car maker of note. James May may object to the Nurburgring factor in the suspension set-ups of many road cars (and we do have some sympathy for his point of view), but the sometimes extreme nature of the Nurburgring’s surfaces – and its endless twists and turns, uphill and down – do offer car makers an easily accessible place to test cars in the (almost) real world.
