The Car Connection's Take

TCC Rating

8.2

TCC’s Bottom Line
It's the same V-6 blast to drive as the far more sexy A7, which makes the 2012 Audi A6 a little irrelevant for those not fixated on five seats or four cylinders. The 2012 Infiniti M sedans are true super-sedans, delivering sharp handling, scorching performance, and impressive comfort, with a beautiful but not overwrought design inside and out. The 2012 Mercedes-Benz E Class models have sharper driving appeal than in the past, while also returning to the classy interior appointments and vault-like construction that have made them longtime luxury benchmarks.
