GM to double size of battery lab

General Motors says it will spend $8 million to double the size of its Global Battery Systems Lab, which the company claims is the largest and most technologically advanced automotive battery lab in the United States. GM says the expansion will speed up the development of hybrid and electric vehicles, such as the upcoming Chevrolet Volt, by improving on-site testing of battery cells and systems. When finished, the lab will be 30,000 square feet bigger than it is now, for a 63,000-square-foot total.

McLaren 650S Sprint revealed – debuts at Pebble Beach

The McLaren 650S Sprint arrives to hit the track The arrival of the McLaren 650S in February (and the end of the 12C, unless it’s being replaced by the McLaren 625C) meant, in all probability, that the various hardcore versions of the 12C would be replicated for the 650S. We’ve already has the new McLaren 650S GT3 at Goodwood this year, and now we get the car that fills the gap between the 650S and GT3 version for McLaren owners to take to the track – the McLaren 650S Sprint. The 650S Sprint – which we assume replaces the 12C Sprint – keeps the 650S’s 641bhp V8 but adds a hefty dose of track specific updates to make the Sprint more focused and with sharper responses.

Take note, Porsche. The exterior of the Rapide is a joy, with hidden door handles keeping the lines sleek, LED sidelights and bi-xenon headlights and big, 20″ alloys.
