No longer will fumbling with a cellphone or reaching for a radio dial dangerously distract drivers. In October, BMW debuted the world's first-ever gesture control in a car, allowing drivers to answer calls, use navigation, and adjust audio, all with conductorlike hand waves. That makes everyone safer. It also hints at the potential for hands-free driving. If that weren't innovation enough, in U.S. models, BMW also took up to 190 pounds off the car's weight, and improved fuel efficiency, by using carbon fiber in the chassis. That helps make the frame stiffen which enhances performance. Luxury details also make the car feel like it belongs in a pricier class: Massage seats for rear passengers are helpful on long rides, LEDs in the moon roof mimic a starry sky, and programmable scents, like "woody," emanate from the dash.
