Tesla Unveils All-Electric Class 8 Semi Truck

Tesla has revealed more details concerning its new, all-electric Class 8 Semi.
In a scene reminiscent of a Rolling Stones concert in the 1960s, Tesla CEO Elon Musk emerged from a silver Tesla Semi at a SpaceX hanger in Hawthorne, California, packed with raucous fans.
For starters, Musk noted that the truck will feature a 500-mile range on a single battery charge, which he said would allow fleets to “go out to the middle of nowhere and return.” Equally important, he said that a planned network of global, high-speed, Direct Current charging stations would give the truck an additional 400 miles of range — and compared that to the 15 to 20 minutes it takes to fill up a diesel-powered Class 8 truck today, adding that drivers are required to take rest breaks anyway. “Once you’re done with your break,” he said, “your truck will be ready to go.”
Fleets that use solar-powered “mega-chargers” would see tremendous savings, he added, since their trucks would be “powered by sunlight,” while adding that the batteries receive additional electric energy through the truck’s regenerative braking system, which Musk said was so powerful drivers would rarely need to use the brake pedal.
Musk likely raised more than one eyebrow when he claimed that thanks to its optimized traction and instantaneous torque, the new Semi would be able to go from 0 to 60 mph in five seconds without a trailer, and 0 to 60 in 20 seconds when pulling a fully loaded trailer. Equally important, Musk said the unique characteristics of an electric powertrain’s torque delivery with no clutch actuation or gear shifts would allow the Tesla Semi to climb a 5% grade while maintaining a constant 65 mph.
Musk also touted the simplicity of the design and its operation, noting that there was not transmission or gears that …Read the rest of this story
