On April 27, 2012 at Wendover Airfield in Utah, USA, the Volvo-built truck, which is owned and driven by Boije Ovebrink, broke records in two international speed standards. The new records are for the standing kilometer (two-thirds mile), a record already held by the hybrid truck, and the flying kilometer1.
The provisional results2
- Standing Kilometer – 153.252 km/h (95.245 mph) (previously 152.253 km/h (94.605 mph)
- Flying Kilometer –236.577 km/h (147.002 mph) (previously 218.780 km/h (135.943 mph))
Mean Green pumps out a massive 2,100 horsepower (1,566 kW) and nearly 5,000 lb-ft. (6,770 Nm) torque – of which, 200 horsepower (149 kW) and 885 lb-ft. (1,198 Nm) of torque come from the electric motor. Aerodynamics also plays a vital role in achieving top speed, so Volvo designers selected a North American VN cab and sculpted the optimal aerodynamic shape for the truck.
Tires capable of withstanding the enormous stresses are essential and Goodyear has worked closely with Volvo on the project and specially developed the tires for Mean Green. Zero to 100 km/h in four seconds is impressive for a car, let alone a truck weighing six tonnes. But that is exactly Boije Overbrink achieved on his way to breaking a world record and he did it on Goodyear tires. They are hand-built and based on 495/45R22.5 Marathon Long Haul Drive truck carcasses, capable of withstanding the enormous torque and speeds that Mean Green develops.
1Standing kilometer – The truck starts off from a standstill, spanning the 1,000-meter course in one direction and then the other. The average speed from the two runs is noted as the official figure. Flying kilometer – The truck is in motion prior to spanning the defined 1,000-meter course in each direction.
2The new world records are subject to FIA recognition, which will occur in about 30 to 60 days.
