Rare foreign cars head to Carlisle this weekend

Every spring, Carlisle, Pa., (otherwise known as the Woodstock of the classic-car hobby, a title it now fully shares with Hershey) hosts a weekend event just for foreign cars. Last year, over 1,000 cars gathered in central Pennsylvania, with rare foreign machinery making its way from all over the lower 50 and parts of Canada. The longest-traveled cars we spotted last year wore British Columbia plates, which should give you a clue as to the event's following, though we're still unsure which cars we spent the longest time gawking at.

2013 Mercedes SLS Electric Drive: Paris 2012

The electric SLS – the Mercedes SLS Electric Drive – has been shown at Paris 2012 ahead of a 2013 launch. Mercedes are billing the electric SLS as the most powerful production electric car in the world, and with an output of 740 horses from its four electric motors – one at each corner – that’s no surprise. That output – and a torque figure of 738lb/ft – makes the electric SLS a whole heap more powerful than its ICE counterpart and allows it to get to 62mph in 3.9 seconds.

Future Audis may time traffic lights for you

Here's a trick efficiency-chasing hypermilers have been using for years: spotting the cycles of stoplights from 100 to 200 yards out and letting the car coast up to the light just before it turns green, then carrying on without ever letting the car come to a complete stop. These hypermilers, along with professional truck drivers, do this because they know that accelerating from a standstill burns the greatest amount of fuel, and because letting a car coast up to the light with the automatic transmission downshifting by itself is easier on the transmission than stomping on the brakes right beneath the stoplight. Oh, and it's easier on the brake pads as well.
