It's funny what you pick up at the most unlikely of places... At last week's Truck & Bus World Forum in Gothenburg Biglorryblog stumbled across this vehicle--which is news to yours truly and I suspect many BLB readers too. It's called the Renault Premium Optifuel Concept Optifuel or 'Optilab'and is a based on a super slippery Premium tractive unit and highly-modified Lamberet trailer.

Apparently it was unveiled in Brussels last September (no one tells me anything!) and according to the French truck maker it: "Proves that lower fuel consumption in heavy vehicles is not limited to the search for alternative solutions to diesel. With a more aerodynamic cab, a 30 cm longer nose, the concept vehicle uses more than 10 % less diesel and cuts CO2 emissions compared with a conventional truck."
Renault goes on to say: "Designed to handle high-volume intercity transport, the Optifuel/Optilab test vehicle supports a research programme aimed at reducing diesel consumption by 15% and lowering CO2 emissions in comparison with a current vehicle (i.e. a Renault Premium Long Distance 450 Euro-4). To achieve this goal, Renault Trucks will continue its work to optimise the driveline, engine and gearbox, especially with regard to ancillary energy use. The project will also serve to test a new high performance fuel, in collaboration with Total."
Moreover, it says: "The second source of economy comes from reducing rolling resistance, achieved by the new generation of tyres developed by Michelin, a partner to Renault Trucks in this project. Nevertheless, the greatest savings in diesel consumption and CO2 emissions comes from the exhaustive work done on the aerodynamics of the outfit."
