700 horsepower Porsche GT2 RS is the wildest 911 ever

The Porsche 911 comes in a variety of flavors, each filling a certain taste for a certain customer. Sitting atop the range is the new 911 GT2 RS. In previous generations, the GT2 had a bit of a reputation as a widowmaker, a 911 with massive power that could snap and bite with the slightest agitation. Porsche says the new model has been civilized, but with 700 horsepower going to the rear wheels, we're sure it's going to be as mad as ever. Power comes from a highly massaged version of the 3.8-liter flat-six from the 911 Turbo S. The rear-mounted engine makes an outrageous 700 horsepower and 553 lb-ft of torque. Like we previously reported, the new car will use water injection to help keep things cool. The only transmission is Porsche's PDK. While enthusiasts may lament the loss of the manual, the RS models have always been about performance above all else. Simply put, the PDK is the better performance option. All that power translates to a 0-60 mph time of 2.7 seconds and a top speed of 211 mph. The engine makes 80 more horsepower than the previous model. That makes it the most powerful road-going 911 ever built. In fact, the 887 horsepower 918 Spyder is the only road-going Porsche that makes more power. The fact that Porsche trusts all of that power to go to the rear is both thrilling and terrifying at the same time. In order to manage traction, the GT2 RS gets a number of upgrades. Rear-wheel steering has become commonplace in the 911 lineup, so it's no surprise to see it here. Sticky tires with 265/35 ZR 20 section rubber at the front and 325/30 ZR 21 section rubber at the rear keep things planted. That comically large rear wing adds downforce, adding to stability. The car gets standard carbon ceramic brakes. While some people prefer traditional rotors for the street, like the PDK, this is all about performance. A number of intakes and outlets complement the rear wing and maximize aerodynamic efficiency. It's a bit of a surprise that with all the focus on downforce, the GT2 RS still manages to top out at 211 mph. The hood, front wings, wheel housing vents, door mirrors, side air intakes, parts of the rear end, and a number of interior components are all made from carbon fiber. The roof has been made of magnesium. If you want to drop any pretense of civility and comfort in the pursuit of speed, Porsche is offering a Weissach package that shaves off another 40 pounds from the already impressive wet weight of 3,241.

GM recalling 778,000 Cobalts and G5s, six deaths reported

General Motors has announced that it will be recalling 778,562 compact cars after six people were killed in accidents, partially due to the airbags' failure to deploy. An issue with the ignition switch is causing the airbag issues, as well as causing the engine and other components to shut off without warning. The recall covers the 2005 to 2007 model year Chevrolet Cobalt and 2007 Pontiac G5. (Note that the Cobalt pictured above is a 2009 model.)
According to a report from Automotive News, a number of factors can cause the ignition to switch out of the run position, including weights on the key ring, rough or bumpy roads or other "jarring" events. Any of these situations could lead to some vehicle components not functioning properly.
There have been five fatal front-impact crashes that took the lives of six people, although as a GM spokesman noted, all five of the crashes happened off road and at high speed. In each of these cases, though, the lack of airbags wasn't the only lethal factor - alcohol and failure to wear a seat belt also played a role. Outside of the fatal accidents, there have been 17 other crashes where airbags didn't deploy. It's unclear if any of these crashes were caused by the engine shutting off.

Gordon Murray, F1-driven production and .. the Pontiac Fiero

Gordon Murray's design and engineering chops are unquestionable. But does his carmaking approach owe something to the short-lived Pontiac Fiero, a scrappy little car program that emerged from GM against serious resistance? Murray had a Formula One career that ran from 1969 to 1991, with stints at Brabham ('69 to '86) and McLaren ('87-'91), that resulted in several shelves' worth of trophies for the cars he was instrumental in designing. He moved on to McLaren Cars, the consumer side of things, where, during his tenure from 1991 to 2004, he helped design the McLaren F1 and the Mercedes-Benz SLR McLaren, two cars that took learnings from his two decades in Formula One. What do all of these cars have in common? Three things: They are light. They were built in limited numbers. And they were (and are) exceedingly expensive—when the McLaren F1 debuted in 1994, it stickered at $815,000. Murray went on to establish Gordon Murray Design in 2007. GMD has created some interesting concept vehicles, such as the diminutive T.25 city car (94.5 inches long, 51.1 inches wide and 55.1 inches high), and the OX, a lightweight truck for the developing world that packs like an IKEA shelf and is working toward realization through a worthy crowdfunding campaign established by the Global Vehicle Trust. Now he has created a vehicle manufacturing company, Gordon Murray Automotive, that will use manufacturing methods that he developed under the moniker "iStream." Unlike a unibody, there are the "iFrame," a cage-like construction made with metallic components, and the "iPanels," which are composite. The panels aren't simply a decorative skin; they actually provide structure to the vehicle. Presumably this has something of the F1 monocoque about it. Going back to the three elements, (1) this arrangement results in a vehicle that can be comparatively light; (2) Murray has indicated that his manufacturing company will be doing limited-run production; and (3) to launch Gordon Murray Automotive they are going to be building a flagship model, about which Murray said, "With our first new car, we will demonstrate a return to the design and engineering principles that have made the McLaren F1 such an icon." Which seems to imply that it will be on the pricey side. According to the company's verbiage, "iStream forges an entirely new production method that defies conventionality with its Formula One-derived construction and materials technologies." It also sounds a whole lot like ...
