Toyota last month announced it will begin testing this summer a hydrogen fuel-cell powered Class 8 tractor at Southern Cal ports. The rig, built off of a Kenworth T660 tractor, generates more than 670 hp and 1,325 lb.-ft. of torque. It’s powered by two Mirai fuel cell stacks and a 12kWh battery, giving the drayage truck more than 200 miles per fill under normal operation, the company says. The truck can haul loads up to 80,000 pounds, Toyota notes.
To tout the rig as a capable diesel replacement, Toyota shortly after debuting the tractor released the video below, showing a simulated drag race in which the Mirai-powered KW races a diesel-powered Kenworth. Both vehicles have a GVW of 35,000 pounds, according to the video. How does the hydrogen-powered rig compete? Check here video below to find out:
Affected tractors are equipped with an automated Eaton UltraShift Plus or Eaton Advantage Transmission with right hand stalk shifter. In the affected trucks, the display on the instrument panel can indicate “N” when the shifter is set into “D” or “R,” causing the truck not to move.
The new “health-based requirements” will need to be met before a driver is allowed to register his or her truck through the Department of Motor Vehicles, CARB says. For older vehicles, CARB says they must be either replaced with a 2011 or newer vehicle or repowered with a 2010 or newer engine.
