Volvo tweaks long-haul I-Save algorithms to improve fuel economy 27 August 2020

The Volvo FH with I-Save is now being launched in an even more fuel-efficient version that can cut fuel costs by up to 3% more than the previous generation, or 10% compared to a truck without the technology.

The new Volvo FH with I-Save is part of Volvo Trucks’ new European product range introduced this spring. I-Save includes many fuel-saving systems, of which the most important is the Volvo D13TC engine. Volvo’s 13-litre turbo compound engine, launched at the start of 2019, is the company’s most fuel-effective engine to date.

With the launch of the first-generation Volvo FH with I-Save in 2019, Volvo Trucks showed that this solution could slash the cost of fuel – diesel and AdBlue – by up to seven percent compared to a truck without I-Save equipped with Volvo’s conventional 13-litre engine.

With the new-generation Volvo FH with I-Save, Volvo Trucks’ product developers have reduced fuel consumption even further. Through software updates based on user data analysis, the balance between fuel consumption and driveability has been refined and optimised, leading to a further reduction in fuel consumption when driving in Eco mode.

In addition to an upgrade of I-Save, the new Volvo FH has a more aerodynamic design. To save even more fuel, I-See now has a new function that enables the truck to detect when it´s efficient for the engine to rev up slightly and then freewheel, even on roads that look flat to the human eye.

“This result means that by choosing the new Volvo FH with I-Save, hauliers can reduce their fuel consumption by up to ten percent compared to an ordinary Volvo FH equipped with our 13-litre engine with Euro VI step D.” The difference in fuel consumption is computed by comparing the costs of diesel and AdBlue for I-Save: D13TC Euro VI step D with the long haul fuel package, with D13 eSCR Euro VI step D without the long haul fuel package. However, Volvo points out that the actual fuel economy varies according to many factors, such as the driver’s level of experience, use of cruise control, the vehicle specifications, vehicle load, actual topography and current weather conditions.

The new Volvo FH with I-Save will be available to order in European markets starting from September 2020.
