BMW rolled into town last night with a fleet of Hydrogen 7 sedans for us to test drive. Having already driven hydrogen cars from Honda and GM, we were intrigued to get behind the wheel of a hydrogen Bimmer, which differs from most other hydrogen-powered cars in that it doesn't rely on a fuel cell and electric drive train. Instead, it uses a modified version of the BMW 760Li's V-12 internal combustion engine to burn hydrogen in the cylinders in the same way as gasoline. It also differs from the pack in that that the hydrogen is stored in a liquid state rather than as a gas. Check out our gallery of the experience and more details on the car here.

This Sunday morning, our clocks spring forward one hour to mark the beginning of daylight saving time.

In this Tech Minute, CNET's Kara Tsuboi reports on some ways technology can help ease the transition.
