NHTSA may investigate Grand Cherokees over fuel-tank fire hazard

The Jeep Grand Cherokee from the 1993 to 2004 model years may be investigated by federal safety regulators after a complaint that its fuel tank is an exposed fire hazard that may have contributed to hundreds of deaths. Last month the nonprofit Center for Auto Safety complained that the SUV's fuel tank extends below the rear bumper and is inadequately protected from crashes and rollovers. The vehicle's fuel filler neck also tears off in crashes, said the center's petition for an investigation and recall.

Red Bull Racing's X2014 concept car to feature in GT6

Red Bull Racing has revealed its X2014 concept car that will feature in the upcoming Gran Turismo 6 racing game. The Formula 1 team's chief technical officer Adrian Newey worked alongside Polyphony Digital to develop the road car, which is obviously very much inspired by F1 car design.

Guinness returns fastest production car world record to Bugatti

The Bugatti Veyron Super Sport is back as the “Fastest Production Car” after Guinness World Records looked deeper into the claim, and decided that Bugatti's eliminating the speed limiter in order to set a record did not bar the vehicle from holding the title. “The focus of the review was with respect to what may constitute a modification to a car's standard specification,” said Guinness in a statement. “Having evaluated all the necessary information, Guinness World Records is now satisfied that a change to the speed limiter does not alter the fundamental design of the car or its engine.” Now the company owns both the open- and closed-top speed records with the Veyron Grand Sport Vitesse and the Veyron Super Sport.
