Big Mack with a side order of turbo
TRUCKS that don’t guzzle diesel were all the rage at the WasteExpo 2016 recently held in Las Vegas, and foremost among these green trucks were the electric Mack refuse removal trucks.
Designed as an alternative driveline, the Wrightspeed Route give the big Mack a side order of turbo to extend the range of the electric vehicle powertrain as far as the driver can get.
The Wrightspeed Route powertrain uses electricity to deliver 100% of the vehicle’s propulsion. The system features an advanced plug-in capable battery pack that enables a purely electric range of up to 38 kilometres. When the battery charge is depleted, an 80 kW, fuel agnostic Fulcrum Turbine Generator, which can operate on natural gas or diesel fuel, recharges the batteries, enabling Routeequipped vehicles to have unlimited range with refueling.
Additional recharging comes from the Route’s 730 kW regenerative braking system, which generates electricity as the vehicle comes to a stop. Electricity from the battery pack powers four geared traction drive electric motors, enabling the Route powertrain to power vehicles up to 33 tons on grades as steep as 40%. With full torque available from zero rpm, the Route driving experience is comparable to diesel-powered trucks. — WR.
The first Mack to use a turbine that charges batteries that in turn power an all-electric drivetrain.
