Latest Allison software shows big savings

An independent test carried out over the course of 18 months by Métropole d’Aix-Marseille-Provence showed that Allison Transmission’s FuelSense 2.0 software allowed up to 12 per cent fuel savings for some of the French city’s municipal vehicles.

FuelSense 2.0 software was installed in four Renault Trucks D 4×2 vehicles, equipped for refuse collection. ‘Eco’ mode was activated in the software instead of the ‘Performance’ mode. The vehicles traveled an average of 1,200 km/month, resulting in around 21,600 km each during the duration of the test.

The fuel savings obtained with Allison’s FuelSense 2.0 reached up to 12 per cent. In addition to the significant savings in terms of fuel purchase, these four vehicles reduced their CO2 emissions by almost five tonnes, while maintaining vehicle performance.

“The price of fuel encourages us to study all possible solutions to reduce our consumption. By performing this test, we did not expect such savings: 12 per cent is more than significant! And the feedback we have from drivers is very positive: the vehicles have kept their performance,” explained Stanislas Kogut-Kubiak, maintenance manager at Métropole d’Aix-Marseille-Provence.

Based on this test, the conurbation has chosen to install FuelSense 2.0 on 24 other vehicles in its fleet to reduce its consumption and CO2 emissions.

“Our fleet is made up of 160 refuse vehicles. 100 per cent of them are equipped with Allison transmissions. We have chosen Allison transmissions for a long time. The investment is quickly paid back. Allison transmissions are robust and reliable and rarely require downtime, making maintenance easier,” said Kogut-Kubiak.

The UK’s Fife Council also carried out a six-month test on two Mercedes-Benz Econics refuse collection vehicles. These vehicles worked in two shifts from Monday to Friday, with different types of waste and traveled 21,000 km.

For six months, the fuel savings on these vehicles was on average 8.85 per cent . This result led Fife Council to install FuelSense 2.0 on 11 other refuse vehicles. In addition, it ordered 11 new vehicles equipped with new FuelSense 2.0 software. With these two vehicles newly equipped with FuelSense 2.0 and these 11 new additional vehicles, the potential for reducing the city’s CO2 emissions is 124 tonnes.

Allison Transmission’s FuelSense 2.0 software features DynActive Shifting. At the heart of this technology is an intelligent algorithm which continuously assesses driving conditions to best adjust gear changes. This algorithm takes into account different factors, such as vehicle weight, road gradient or the frequency of stops and starts.
