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.

Automotive startup company Aptera Motors, promoter of the weirdly styled, three-wheeled 2e electric car, shut down on Friday, saying it was out of money.

"This is a difficult time for everyone connected with our company because we have never been closer to realizing our vision," CEO Paul Wilbur said in a statement.
