The proposed EPA efficiency rule requiring a 24% increase in efficiency is a very low bar which will block very inexpensive and inefficient trucks from the market built between 2019 and 2027. Newer trucks which meet the standard cost an extra $10k to $20k, but recoup that difference in fuel savings over 24 months at current fuel prices. A minimum efficiency standard will help US and European truck manufacturers. Why a 10 MPG Peterbilt semi is a really big deal A 54% fuel savings is no small thing - roadandtrack.com - April 2013 Cummins and Peterbilt Motors have co-developed a tractor trailer that averages nearly 10 mpg under real world driving conditions as part of the Department of Energy's Super Truck program. The Class 8 Peterbilt 587 powered by a Cummins ISX15 engine averaged 9.9 mpg during testing last fall on U.S. Route 287 between Fort Worth and Vernon, Texas. The testing was conducted over 11 runs (more than 11,312 miles) meeting SAE International test standards and the tractor-trailer had a combined gross weight of 65,000 pounds. The big rig features a higher-efficiency engine and an aerodynamic tractor-trailer that significantly reduces drag. The truck also includes a system that converts exhaust heat into power delivered to the crankshaft, electronic controls that use route information to optimize fuel use, tires with lower rolling resistance and lighter-weight material throughout. Single-digit fuel economy might not sound like a big deal, however today's long-haul trucks typically achieve between 5.5 and 6.5 mpg. The 54 percent increase in fuel economy would save about $25,000 annually based on today's diesel fuel prices for a long-haul truck traveling 120,000 miles per year, as well as translate into a 35-percent reduction in annual greenhouse gases per truck.
