Car of the Future (NOVA - PBS)

Tom Magliozzi has a problem. The wacky cohost of NPR's Car Talk needs to replace his beloved 1952 MG roadster. But in today's car market, where should he turn? Is new technology about to transform the way we drive? Tom and his brother Ray hit the road in this program for a lighthearted but shrewd take on America's four-wheeled future. John Lithgow narrates as Tom and Ray mix their trademark slapstick with serious nuts-and-bolts analysis of what it will take to make our autos more energy-efficient. With a quarter of all the oil ever consumed guzzled up in the last decade and oil supplies being drawn down faster every day, the brothers' screwball automotive odyssey doubles as a serious environmental wake-up call.

Tom and Ray explore everything from the glitzy, high-octane North American International Auto Show in Detroit to the earnest do-it-yourselfers of the AltWheels Festival in Boston, where the brothers squeeze, clown-car style, into a tiny three-wheeler that, even at 100 miles per gallon, isn't quite ready for the rush-hour commute—it can't go in reverse.

A distinguished group of engineers doubles as Tom and Ray's straight men, including Lee Lynd of Mascoma Corporation, who is working to bioengineer microbes that can produce ethanol from plant wastes, and Amory Lovins of the Rocky Mountain Institute, who is developing an ultralight, full-size "green" car that is efficient and almost indestructible.

Also appearing are Andy Frank of the University of California at Davis, whose lab has developed a plug-in hybrid vehicle that "fills up" from an ordinary electrical outlet, and Martin Eberhard, founder of Tesla Motors, who wants to prove that battery-powered cars can be fast, stylish, and take you 250 miles on one charge.

Even representatives of the giant automakers make an appearance, despite their penchant for producing 500-horsepower, gas-guzzling road machines that even a couple of car nuts like Tom and Ray find excessive—as the brothers emphatically point out to a cornered Detroit executive. A decade ago, Toyota paved the way to more efficient vehicles with its Prius. But will our current romance with hybrids lead to a breakup between Americans and their big, high-powered automobiles?
