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.

Koenisgesgg Agera R BLT impounded by China’s customs

The one-off Koenigsegg Agera R BLT has been impounded by China’s customs officials as they believe it was being smuggled in to China. When we reported the Agera R BLT had been created, we also noted that it was already crated up and on its way to China for the delight and delectation of its new owner. Unfortunately, it looks like China’s Customs officers read the same news and were ready and waiting for the one-off Agera.

Audi A1 quattro prototype

The Audi A1 quattro snow testing in Canada It did seem a strange omission by Audi not to have a quattro drivetrain for the ‘Only Premium Brand in its Sector’ Audi A1. And it was that lack of a quattro system for the A1 which apparently stopped the car that ended up being the Audi A1 1.4 TFSI from being launched as the Audi S1 at Paris last year. All of which has no doubt spurred Audi on to see development of a quattro platform for the A1.
