Opel shows off all-electric One Euro Car concept

It's saving most of the details for the Frankfurt Motor Show next week, but GM subsidiary Opel has now offered up the first glimpse of its all-electric One Euro Car, which seems bound to turn a few heads on the show floor. The car's name comes from the company's promise that the it will consume just one Euro's worth of energy (or about $1.40) for every 100 kilometers, though there's no indication of a price for the car itself other than that it'd be "affordable" -- if it ever goes into production, that is. Otherwise, the company's only saying that it will boast a top speed of 120 kilometers (or 75 miles) per hour, room for two, and a total weight about a third that of a modern compact car.
