^^ Haha!
There's a good story online where the Jag engineers used to race Cossies on the M40 in it!
The van was built to drive in city traffic and was a very important part of the XJ220 development as we had the test track at Millbrook to do the high speed work but nothing would test the car in city traffic,and Jaguar would not like to have bad press with a 220 at the side of the road, so the van was built as a test bed for every day driving in gridlock conditions.
Its for real. Was built by TWR in the early 90's as a rolling testbed.
It was lighter than the 220 & would hit 60 quicker!
Top speed at Millbrook was 170 mph. At that speed it was drifting across the whole track.
One lucky engineer (Patrick Walker) used to take it home at weekends for milage accumulation. He used to sit in the middle lane of the M40 in 2nd gear waiting for a Sierra Cosworth to come up behind & flash him to move over, then he'd plant the loud pedal && leave the cossie for dead
