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.

The Corbin Sparrow was the clown car of tomorrow

The Corbin Sparrow doesn't so much resemble a car as it resembles an oversized Dutch clog left on the carefully manicured lawn of a modern art museum.

Now it seems that BMW are looking for a new way to sell their new range of electric cars – the BMW i3 and BMW i8 – which are about to hit the road and offer car buyers the first chance to jump in to a ‘Premium’ EV. So with a new market place potentially opening up, BMW has already appointed ‘i Geniuses’ at many of their UK dealerships to answer buyers’ question on the i3 and i8, and now they’re going a step further in a move that looks set to undermine, or even replace, BMW car salesmen (and women).
