So far, 2010 has been a very good year for Audi in the U.S. market and diesel engines are playing a part in the surge. Right now, Audi is only offering two TDI models in this market: the big Q7 SUV and the compact A3. In both cases, diesel market share is far exceeding initial projections. Audi had expected diesels to account for about 18-20 percent of the sales of those models, but the TDI made up 56 percent of all A3 sales in February. The Q7 is now up to 40 percent TDI after several months in the low 30 percent range.
In the first two months of 2010, sales of the A3 have more than doubled compared to the same period a year ago with almost all of the extra sales being diesels. Like most other SUVs, the Q7 is down for the year but the availability of the TDI has definitely cushioned the blow. Perhaps the success of the A3 and Q7 will prompt Audi to expand the diesel lineup here, including their biggest volume model the A4.
