Renault working on fuel consumption optimisation

As the Australian economy starts to see a steady increase in fuel cost, improving fuel economy in the commercial vehicle space is becoming a top priority. That's why Renault has put the Master van series through an optimisation program to achieve fuel economy improvements across the range.

Reportedly, the company has been looking for efficiencies in the driveline to cut fuel consumption and, as a consequence, produce lower emissions. All Renault Master models now use the same engine and driveline, differentiated only by the mode of the six-speed transmission, with options of manual versions and an automated manual transmission known as Quickshift.

The Renault engineers have come up with a number of small changes to improve driveline performance: They have modified the cooling circuit resulting in a faster warm up for the engine components. Low drag oil and power steering pumps have been redesigned to further reduce parasitic losses within the system.

Further fuel efficiencies have been achieved by fitting lower rolling resistance tyres as standard. The gearboxes now use a lower viscosity transmission oil, further reducing driveline losses. Renault has also introduced a computer controlled alternator with, what it calls, an optimised recharge strategy, known as Energy Smart Management.

For the manual transmission versions, Renault claims fuel consumption has been reduced to 8.7-litres of diesel per 100 km on the combined cycle (previously 9 litres). On the urban cycle, the claim is consumption falls to 10.2 l/100km. 

“The Renault Master has been very well received in the Australian market since the launch last February, but with these meaningful improvements to the whole-of-life costings, the Master range has just become even more appealing,” said Lyndon Healey, Renault LCV Brand Manager.
