After it got bored filming commercials with Van Damme and girls that destroy everything in their way with a truck, Volvo decided to go after a world speed record. So it started build a one of a kind machine: the Iron Knight truck. With 2400 hp, 6000 Nm of torque and weighing 4.5 tonnes, the Iron Knight has a power-to-weight ratio above 0.5 hp/kg. The mid-mounted engine is a modified D13 unit with water-cooled intercooler and four turbochargers. The I-Shift Dual Clutch transmission maintains torque delivery during gear changes. Apart from a reinforced clutch (the discs and pressure plates are made of a sintered material), the Iron Knight uses the same gearbox that is fitted to series-manufactured Volvo FH trucks.
