That's an 11 wheels Citroen purpose made for Michelin, to test truck and van tyres at high speed.
It weights 10 tonnes, can reach 180 km/h, and it's powered by two Chevrolet Corvette engines.
Remember the Isdera Commendatore 112i from Need 4 Speed II? Did you want one back then?
If yes, I have some good news and some bad news. The good news is that it's for sale. The bad news is the same, it's for sale, as in there is just one of these in existence, so it's not going to be cheap.
