The “Iron Knight” broke the world speed records for the standing start 500- and 1000-meter distances at a closed-off track in northern Sweden.The record run was carried out at a closed-off test track in northern Sweden and with an average speed of 169km/h and a time of 21.29 seconds.


The record-breaker is custom-built in every respect apart from the D13 engine and the series-manufactured I-Shift Dual Clutch transmission.The “Iron Knight” packs a mid-mounted diesel engine modified with a water-cooled intercooler and four turbochargers, producing 2,400 hp and 4,425 lb-ft of torque and weighs 4.5 tonnes giving the Iron Knight a power-to-weight ratio above 0.5 hp/kg. The Iron Knight uses the same gearbox that is fitted to series-manufactured Volvo FH trucks.
