Hybrid passenger cars, which combine a gasoline engine and an electric-drive system, are now routinely available at dealer showrooms. Now, Mack Trucks will soon begin developing a hybrid work truck, which will combine a diesel engine with an electric-drive system.
Mack recently received a $1.2 million contract from the Southwest Research Institute to develop such a hybrid truck for use in refueling operations at U.S. Air Force bases. Anticipated advantages for the hybrid vehicle include improved fuel economy, reduced emissions and longer engine and brake life. Working with strategic partner Enova Systems, Mack plans to deliver a prototype in March 2005.
