2011’s Best Gadgets: Cars

For its next generation of cars, Audi (audi.com) aims to transform the driving experience with a raft of innovations, relying largely on a new mobile processor called Tegra that generates high-resolution graphics quickly. Drivers will be able to program the car’s instruments to display a variety of information: Arrows indicating direction will get larger as a turn nears, for example. And the car itself will be able to maintain an Internet connection that supports up to eight devices being used by passengers.
