‘Mean Green’ is a unique hybrid truck built by an enthusiastic team at Volvo Trucks. They plan to use it next spring to beat the world speed record for the standing kilometre and behind the wheel is Swedish truck racing ace, Boije Ovebrink.
“The absolute elite among Volvo’s hybrid technology experts are the driving force behind the project. They are true enthusiasts, every last one of them. I’d go so far as to say that ‘Mean Green’ is the world’s fastest hybrid truck,” says Ovebrink.
To understand how he can make this claim with such confidence, we need to rewind to November 2007. Ovebrink had just beaten his own standing kilometre record from 2001 for trucks with a maximum displacement of 16 litres. He achieved this by reaching an average speed of 158.829 km/h with his red Volvo NH16 - a.k.a. ‘The Wild Viking’. After winning he met Staffan Jufors, President and CEO of Volvo Trucks, who asked him, “Do you plan to sit down and twiddle your thumbs now, enjoying the fame that comes with being world champion or do you have any new ideas?” Ovebrink replied: “I’d like to build the world’s fastest hybrid truck.”
“The idea met with approval, but at the time I had no idea about the fantastic technology Volvo had in the pipeline,” he recalls.
Planning for the hybrid got under way, but suddenly, however, a Czech truck racing team claimed they had beaten Ovebrink’s record. Order had to be restored, so that spring, Volvo engineer Olof Johansson got down to some serious work. He started building a truck that could retake the record, but that could also be reconfigured for the planned racing hybrid driveline. That truck is now called ‘Mean Green’. But the team decided not to install the hybrid driveline straight away.
“I started building the truck from two half frames that had been earmarked for the scrap yard and the American VN cab came from a crash-tested chassis whose cab was totally intact,” he explains.
Weight reduction was absolutely crucial to setting new records. For example, the front axle was milled by experts from Volvo’s engine factory in Skövde, Sweden and reduced from 100 kgs to 57 kgs. Then the gear set for first gear was removed from the gearbox, shaving another seven kgs off.
