Correction: Non-road SCR-equipped vehicles achieve massive fuel savings

Christopher Goodfellow - 27 October 2010

Manufactures of off-road vehicles that have used Selective Catalytic Reduction (SCR) technology to meet Tier 4 Interim emissions standards have achieved four to six percent fuel savings compared to previous models.

Sam Freesmeyer, Director of Engineering at AGCO, told delegates at Integer's Diesel Emissions Conference in San Diego that the company has managed to achieve four to six percent fuel economy in its 2011 models. However, Freesmeyer noted the new models still represented a significant challenge to consumers asking; "Is that enough to justify the increased cost for the customer?"

In the on-road segment Daimler set ambitious fuel efficiency targets. David Siler, General Manager of the Central Region at Freightliner Trucks, told the conference the manufacturer plans to achieve a 20% reduction in fuel consumption by 2020 as part of its Super Truck program. In January the program received a $40m grant from the Department of Technology.

Engine manufacturer Cummins' EPA 2010 models achieved a 6% fuel economy on the previous year and expects to achieve another one or two percent by the end of the year by further tuning its engine.
