  • Volkswagen XL1 (European model), New York City, Dec 2013

    We didn't expect the Volkswagen XL1 to be as much fun to drive as it is. Which makes it doubly a shame that Volkswagen won't be selling its radically efficient, two-seat, plug-in diesel hybrid XL1 model in North America. At a price of € 111,000 (roughly $153,000), the 250 XL1 cars that Volkswagen will build and sell in Europe are akin to a pricier modern-day analogue to the original 2000 Honda Insight. Like that pioneering hybrid, the two-seat XL1 is supremely aerodynamic (its drag coefficient is 0.19), very light (1,750 pounds), and uses a tiny engine paired with an electric motor...
