Lessons Learned Increased Range, Improved Process

Project Portal 2.0 builds on the lessons learned from the launch of the Alpha vehicle in 2017. The first heavy-duty truck was the result of a true skunkworks effort within Toyota that moved from initial concept to a fully-capable drayage truck driving silently out of a Michigan garage in just over a year. Engineers and technicians worked long hours to reconfigure the wire harnesses, electronics and other components of two off-the-lot Mirai fuel cell electric cars to create one of the world's first OEM-built zero-emission heavy trucks.

The results of their work continue to impress. With a gross combined weight capacity of 80,000 lbs. and a driving range of more than 200 miles per fill, the 670-plus horsepower Alpha truck produces 1,325 pound-feet of torque from two Mirai fuel cell stacks and a 12kWh battery. Project Portal Beta maintains these torque and horsepower numbers while also extending the range of the vehicle and pushing forward on other key performance metrics.

"By evaluating the first truck in our test facilities and on the actual roads in the LA area, we made a list of improvements for the Beta truck build process and performance enhancements," said Andrew Lund, Chief Engineer for the project. He continued, "We needed to move beyond a proof of concept, which the first truck accomplished, to something that is not only better than the original but is also more commercially viable."
