BMW caused some purists to get their spark plugs in a bunch by introducing a front-wheel-drive, plug-in hybrid. It’s called the Concept Active Tourer and foreshadows a model the company probably will bring to market next year. (Christophe Ena / Associated Press)
It’s powered by a turbocharged, 1.5-liter, three-cylinder engine and an electric motor for a total output of 190 horsepower. BMW says it will do zero to 62 mph in eight seconds flat and has a top speed of 124 mph. The car can travel on electric power only for 18 miles and charges via a 220-volt outlet.

VW also used Paris to show off two concept versions of the Golf. The GTI, seen here, will still have a turbocharged 2.0-liter, direct-injected engine, with output now rising to the neighborhood of 220 horsepower. It will be available with a six-speed manual transmission or a six-speed, dual-clutch setup. (Antoine Antoniol / Getty Images)
Meanwhile, the BlueMotion has a turbocharged 1.6-liter diesel motor making 108 horsepower and 184 pound-feet of torque. At start-stop function, lighter curb weight and low rolling resistance tires also help improve efficiency. (Antoine Antoniol / Getty Images)
