Some highlights -
The next A3 is coming to the U.S. only in sedan format, whereas the 5-door hatchback continues to be offered in Europe. At 174.8 in. overall, the Audi A3 (concept) sedan is approximately 6 in. longer than the current A3 wagon.
A3 sedans bound for the U.S. will probably feature a choice of two 2.0-liter 4-cylinder engines, one gasoline- and one diesel-fueled. A hybrid and even an electric-powered variant are also expected to join the lineup. A 7-speed S tronic transmission and Quattro all-wheel drive will be available, though front-wheel drive and a 6-speed manual will almost certainly be fitted to base models
