Car of the Future: Engineering for the Environment

Brothers Tom and Ray Magliozzi -- best known as the hosts of National Public Radio's "Car Talk" -- travel to Boston, Detroit, Iceland and Colorado on a quest to find the perfect car to replace Tom's beloved 1952 MG. Examining wide a range of ethanol, hydrogen, electrical and hybrid technologies, the siblings bring their trademark mix of wisecracking humor and comprehensive automotive knowledge to this engaging installment of "Nova."
