 I test drove it on the Autobahn and it is the bomb!  Really fast.  There is a slight lag in the throttle response during highway (Autobahn) overtaking, but I can live with that.  Probably from the turbos.  Using the sequential manual transmission is a blast.  However, the gas mileage is really poor in that mode.  I drove a total of 29 miles all in the SMT mode and used a quarter of a tank.  Assuming a full tank is 16 gallons, I used 4-gallons, or about 7-miles to the gallon.  Too bad.  If you really like sporty driving then get a manual transmission.  That said from a performance perspective, it is almost a perfect car.
