Audi R8

Audi has unveiled the new R8 supercar, closely based on the Le Mans concept that was shown three years ago in Frankfurt. The two-seat car uses a shortened version of the Lamborghini Gallardo platform, and is powered by a 4.2-liter V8 using FSI technology first introduced by the A2. Like the now-obsolete small car the R8 is also constructed of an aluminum space-frame, keeping weight down to 1360kg.

BMW Vision ConnectedDrive (2011) first pictures

This gorgeous two-seat roadster is the BMW Vision ConnectedDrive, set to be unveiled at the 2011 Geneva motor show. Unlike some of BMW’s other Vision-tagged concept cars, this unfortunately isn’t a thinly disguised production car, but a study designed to highlight the company’s driver assistance systems.  However, although BMW has released no details on the engine or layout under the sexy skin, thankfully the Vision ConnectedDrive’s stunning styling (including the shark nose, wrap-around rear lights and layered body) will find its way onto future production BMWs.  For a start sensors in the headlamps and rear lights monitor the traffic situation and the environment around the car, while instead of wing mirrors there are antennas that receive navigation data and transmit other information. Inside the driver has a 3D head-up display, and the system can project information about the chosen sat-nav route so it appears at the exact point of a possible turn-off. The 3D system also displays information in the foreground or background of the display depending on its relevance.

Expert: Fisker Karma's engine packaging, not batteries, likely caused fire

A garage fire last week in suburban Houston has been linked to a Fisker Karma plug-in hybrid, but the company quickly noted that the battery remained intact and unplugged -- and did not appear to be the cause. But if not the battery, then what? More likely, poor packaging in the engine compartment and exhaust routing generated excess heat.
