Clay Siegert, Vice President, supply chain for XL Hybrids says the company’s system can be purchased for under $10,000 with an ROI between 3 and 5 years (depending on duty cycles) while offering users up to 21.2 percent reduction in fuel use in real world conditions. He notes that because the hybrid drive systems provide immediate, usable torque at take-off, fleets can save even more fuel in GM vans by downsizing from the 6-liter V-8 engine to the more fuel efficient 4.8 liter engine with little or no degradation in vehicle performance.
