The Veyron may feature an 8.0-litre, quad-turbocharged, W16 cylinder engine that produces 1001hp, but Mike Harrah definitely has this beat. He’s the proud owner of one of of the biggest semi trucks you will ever see. It pushes over 3,400 hp and is held together with a 40 foot chassis, thanks to a dozen superchargers and 24 cylinders (two V12 engines) that could whet the appetite of any muscle / power / hyper car junkie.
