The transmission in the Veyron is an 8-Speed DSG and the GT-R has an infamously bad 6-Speed DCT. The problems in the first-gen GT-R tranny were worked out for the 2012 MY. This one is NOT a 2012 so it has the older and inferior transmission.
Also, the tires for the Veyron were specially designed by Michelin for the Veyron ONLY. They cost $20,000/set.
Not to be a douche or anything but just correcting you. Veyron has a 7 speed DSG.
