Tests Confirm XL Hybrids’ Claims Tied to Fuel Economy

July 05, 2012

XL Hybrids Inc., a developer of a hybrid electric powertrain designed specifically for class 1-3 commercial fleet use, has released vehicle testing results that validate a 21.2% reduction in fuel consumption achieved with the company's aftermarket hybrid electric powertrain.

The tests were conducted on a light-duty chassis dynamometer test cell featuring a twin-roll Clayton dynamometer. The testing process compares fuel economy performance from the vehicle in its original condition with the performance using XL Hybrids' charge-sustaining hybrid system.

The test was completed using a Chevrolet 2500 Express cargo van fitted with the original equipment manufacturer's 4.8 liter engine and 6 speed transmission over the light-duty Urban Dynamometer Driving Schedule (UDDS) test cycle, which represents city or urban driving routes.

According to the company, XL Hybrids' hybrid electric powertrain is a low-cost, low-risk, bolt-on technology that integrates with the conventional internal combustion engine and transmission. With a 21.2% reduction in actual fuel consumed, the technology can provide a three-year payback in heavy-use fleet applications, or immediate savings when combined with vehicle financing.

"This test provides independent validation of our hybrid electric powertrain for fleet customers," said Justin Ashton, co-founder and VP of business development at XL Hybrids. "We exceeded our target of 20% fuel consumption reduction and our customers are seeing similar results in the ongoing field trials of our hybrid powertrain on their vehicles."
