Audi continues to underscore the importance of the US market to its future fortunes with two world debuts at the Detroit Auto Show. In addition to the R8 V10 that we saw last month, we got our first look at the Sportback concept. The Sportback is a preview of the A7 sedan due to arrive in the next year or so. As expected, this is Audi's take on the four door coupe/sedan idiom. Compared to the Porsche Panamera, this is one actually works. It takes the look we've come to expect from Audi and updates it with slightly sharper lines and a reshaped grille, along with even more LED lighting.

The Sportback name refers to the fastback roofline and Audi boss Rupert Stadler made it clear that the new look will become a common trait in the Audi lineup, beginning with a new A5 Sportback coming later this year. Under the hood, the Sportback gets a 3.0-liter TDI diesel V6 with 225 hp/406 lb-ft paired up with a seven-speed S-Tronic dual clutch gea box. The whole thing is topped off with automatic start stop to give a combined 39 mpg (US). Based on these specs we can't wait for the A7 to arrive.
