I did a few Autobahn miles (Km's) last summer and raced absolutely anything that wanted a go.
I was pleasantly surprised at how quick a Laguna V6 estate was up to the 140mph mark, but obviously dusted him. Along with an Audi RS4, a BMW M3 and new shape M5.
The fasest thing i came across was an Audi R8. He came up behind me and wanted to play. I was doing around 130 in 6th so just rolled her on, he/she (probaly 'he', sorry ladies) was still right there. Dropped into 5th, pulled a little but not enough for a convincing win. Dropped to 4th and bye bye R8.
Raced the new Nissan GTR in Wales. All i'll say is FAST FAST FAST. Never have i been up against something sooooo blisteringly quick. Beat him, but only just. They're not limited and Bike fast!!!!!
