“We have six that have been running for more than 15 months,” says Danny Diaz of Miami-Dade County. “They’ve exceeded our expectations.”

Miami-Dade has a U.S. EPA Emerging Technology grant it expects to offset the incremental cost of further vehicles. How many is the county buying? “A conservative number would be about 15 trucks,” Diaz says.

According to Parker, the Miami-Dade E3s burn some 36 gallons of fuel per day compared with other vehicles in the fleet which use 63 gallons.

Municipalities in Texas, North Carolina, Florida and Indiana haveplaced orders, Parker says. Austin, for example, has ordered four of the hydraulic hybrids (F&F, August 15).

Also operating the pre-production RunWise E3s are the cities of Hialeah and Miami. According to Parker, Miami has purchased five additional Autocar E3s “after operating one truck on city routes during the past year and witnessing close to 50% fuel savings.”

‘Faster, More Dependable, Less Noise’

Operators have reported positive driving experiences and increased route productivity too, Parker says. “The Hybrid is faster, more dependable, experiences less noise in the cab and has not encountered any problems,” Miami operator Scotty Rodgers says in Parker’s release. “The truck moves very smoothly from stop to stop allowing me to get through my route more quickly.”

Parker says it is expanding its Miami-based service network as well. “The service team has helped the fleets answer any questions they might have about the system while recording and validating the performance of the trucks,” the company says. “Key measures include reduced fuel consumption, improved route efficiency, and reduced carbon emissions.

“Importantly, maintenance has been reduced on the brakes which have yet to require replacement and are anticipated to last up to eight times longer than on the conventional fleet also reducing airborne brake dust particulates.”
