Conti’s HDL Eco Plus on Top in Fuel Economy Test

Independent testing conducted in Quebec, Canada has found Continental’s HDL Eco Plus drive tyre to deliver up to 2.4 per cent superior fuel economy versus its test competitors. The test used a controlled evaluation tool based on the Society of Automotive Engineers J1321 test method, reports Conti, however the tyre maker has not disclosed which competitor products were evaluated.

“These results confirm our own internal tests proving that the 28/32nd closed-shoulder drive HDL Eco Plus offers exceptional fuel economy, while still providing competitive overall miles”, states Roger Stansbie, director Tire Technology for Commercial Tires in The Americas. “These results came despite wet weather conditions during the test that would normally minimise the differences between competitor performances due to the reduced coefficients of friction.”

As the drive wheel position is considered to be the most influential for fuel consumption, only the drive tyres were compared. The steer and trailer positions were kept constant.
