Spy Shots: Could this be the 2014 Porsche GT3 RS?

Brenda Priddy & Co. sent us the above photos in an e-mail with the subject line “BREAKING: 2014 911 GT3 UNCAMOUFLAGED!” So, we opened it and found a few shots of Porsche's new rear-engine, mini Panamera in “all black everything” but sporting very little camouflage. If this is indeed the 2014 Porsche 911 GT3 RS, the bodywork is either quite a bit more restrained than that of the outgoing 997.5 GT3 RS, or it's wearing bodywork that won't appear on the 2014 GT3 RS when it debuts at the Paris motor show in September.

BMW's Vision EfficientDynamics concept bound for Frankfurt

BMW has revealed a radical vision for its future performance-oriented models in a spectacularly styled concept car whose combination of M3-rivaling acceleration and Mini Cooper-beating fuel economy will likely make it one of the stars of this year's Frankfurt motor show. Called Vision EfficientDynamics, the one-off coupe is a mobile showcase for lightweight construction and plug-in hybrid drive technology, while featuring a variety of futuristic styling, packaging, aerodynamic, lighting and interior ideas under development at the German carmaker's heavily cloaked FIZ development center in Munich. Many of the concepts are planned for use on upcoming BMW road cars, including an exciting Z10 EfficientDynamics range-topping model due by 2015.
