Very nice and quick too.
When we were waiting for I-30 Dragway to open up I was watching Sky Captain and the World of Tomorrow on the DVD and had the seat massage going.
It is a truly glorious ride. The V12 naturally cancels out the first and second order harmonics with companion cylinders firing on both banks at the same time. It's literally whisper quiet at 80 mph. The night vision works well when traveling in deer country, too.
