With 4,425 pound-feet of torque, it can probably move mountains

Last week, Volvo Trucks announced plans to try and take down not one, but two world speed records using an immensely powerful truck dubbed "The Iron Knight." The attempt took place on a former airfield in northern Sweden where the insanely fast truck was driven by Boije Ovebrink who managed to beat the speed records in the standing-start 500- and 1000-metre categories.

Here are the numbers: the Iron Knight is now the new record holder in the 500-metre distance with a time of 13.71 seconds at an average speed of 131.29 kilometres per hour (81.58 miles per hour). At the same time, it’s also the fastest in the 1,000-metre distance which it completed in 21.29 seconds at an average velocity of 169 km/h (105 mph). If you’re still not impressed, Volvo Trucks mentions during the record runs its impressive truck managed to reach a top speed of 276 km/h (171.5 mph).

How was it all possible? Well, the mid-mounted six-cylinder 12.8-litre engine with its 2,400 horsepower and 4,425 pound-feet of torque was obviously a contributing factor. But it wouldn’t have been possible without the I-Shift Dual Clutch transmission, which was pretty much standard (and the same one used in the FH trucks), with the exception of the reinforced clutch with discs and pressure plates made from a sintered material.

The Iron Knight weighs 4.5 tons (4,082 kilograms) and has a very respectable power-to-weight ratio of more than 0.5 hp / kg. It had to undergo some other changes to increases the chances of setting those two records, with Volvo Trucks’ engineers tweaking the software "to permit the high performance," while some of truck’s electronics had to be removed to shave off weight. For the same reason, the aerodynamically-optimized cab was made from fiberglass. In addition, the side skirts gained huge air intakes to provide cooling for the modified D13 engine found in the company’s FH trucks.
