Audi has unveils the all new 2013 S3 Sportback with aggressive body kit styling, sexy interior design, quad tailpipes, and 18-inch wheels. Underneath the hood is a turbocharged 2.0-liter TFSI four cylinder engine that powers the S3 up to about 300-hp. An all-wheel-drive system will distribute this power to all of the wheels through either the standard manual trans or the optional S-tronic dual-clutch automated system. The new Audi S3 will go on sale early 2013 in Europe.
