Tesla unveils electric Class 8 big-rig truck, and a speedy Roadster
The truck can go up to 800km (500 miles) at maximum weight at highway speed, Musk said. Diesel trucks are capable of travelling up to 1 600km on a single tank of fuel. Musk said diesel trucks were 20% more expensive per mile to operate than his electric truck. Tesla said the truck can charge for 30 minutes and then travel 644km.
The truck has Tesla's latest semi-autonomous driving system, designed to keep a vehicle in its lane without drifting, change lanes on command, and transition from one freeway to another with no human intervention. Reuters reported in August that Tesla was discussing self-driving trucks with regulators in Nevada and California, but the company did not mention full autonomy in a release on the new vehicle.
Later, the semi-truck opened its trailer, and a new Roadster drove out. The car is an updated version of Tesla's first production vehicle. It can seat four and travel 1 000km on a single charge, a new record for an electric vehicle, Musk said. It can go from 0 to 100kmph in 1.9 seconds.
