We're envious. The editors over at AutoblogGreen got to take a 300-mile trip in the Chevrolet Sequel hydrogen fuel cell car. We don't just envy the driving experience, which in a fuel cell car involves completely smooth and quiet acceleration. And it's not just the length of the drive, which might be some sort of record given that the cars were on public roads. We also would have liked to spend time in a car that uses in-wheel motors, four-wheel steering, and all sorts of other revolutionary platform technology. For a full account of the drive, read AutoblogGreen's write-up.
