Is this the new Jeep Cherokee?

Editor's note: Here's the official 2014 Jeep Cherokee, hastily revealed by Chrysler after these unofficial photos hit the web Friday. Spoiler alert -- it looks the same.

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.

GM to drop plans for range-topping Cadillac sedan

Designers recently were taken off the program and reassigned.
