Here’s looking forward to summer. The late, light, balmy evenings, and the launch of the 2012 Audi A6 sedan. Every other Audi seems new or refreshed, so it’s about time the A6 caught up. It gets the usual ingredients: aluminum body parts, optional Quattro all-wheel drive, luxury extras, and a 300-hp supercharged 3.0-liter V6. However, although there are no concrete plans to bring it to the States as yet, there will be a hybrid version with 245 hp and fuel consumption of around 37.9 mpg. A diesel version could be coming west too.
