Audi A3 TDI 2010

The A3 2.0 TDI is Audi's second U.S. TDI clean diesel launch. The A3 2.0 TDI is expected to be on sale at U.S. dealers in April. Audi is betting that drivers will be attracted to the luxury brand's A3, the company's smallest, because it promises to lower fuel costs while maintaining the finer touches of driving an Audi.
