This one shocked me a little, if only for its dramatic drafting speed - Chevrolet Silverado.
Take a fully tuned model into arcade mode on Route X and it puts you up against a full grid of Citroen GT's. I thought I'd be well out of my depth and they'd run off, no. I had to keep going back to lengthen my gearbox and finally got it drafting behind them at up to,,,,,,,,277mph!!!
I think if I took it into an online room and set myself up with some X1's willing to give tows I could get 300mph from it!
Sure, it's got over 900bhp, but let's face facts - it's a humongous truck!
