Lately there’s been some interesting news out of the Volvo Group in Sweden, with both a dramatically aerodynamic tractor-trailer unit offering almost one-third lower fuel consumption, and an autonomous truck. This one really is autonomous, no human intervention required, but it’s not for public roads. Thankfully, I hear many of you saying.

First the fuel-efficient concept truck.

With support from the Swedish Energy Agency, Volvo Trucks has developed a new concept vehicle, the result of a five-year-long research project aimed at creating more energy-efficient vehicles. The new concept truck is said to cut fuel consumption by more than 30%.

“Our concept truck showcases the immense power of on-going technical advances,” says Claes Nilsson, Volvo Trucks president and CEO.

One of the key factors behind the low fuel consumption is its massive 40% improvement in aerodynamic efficiency that has benefited both the tractor and trailer.

Engineers modified the entire rig and optimized it for improved aerodynamics as much as possible. For instance, it uses cameras instead of rear-view mirrors to cut air resistance.

In addition to the aerodynamic improvements, the concept vehicle is fitted with newly developed tires with lower rolling resistance. The trailer weighs two tonnes less than the reference standard trailer, which translates into either lower fuel consumption or the possibility of higher payload. The project also includes an improved driveline. The rig was test driven on Swedish roads late last year.

The aim is to improve the efficiency of long-haul truck transportation by 50%.
