Elon Musk finally gave a date for the semi truck unveiling, via Twitter

Tesla Semi truck unveil & test ride tentatively scheduled for Oct 26th in Hawthorne. Worth seeing this beast in person. It's unreal.

Originally he had stated September as the reveal timeframe for the long awaited electric semi, but October is likely better to give them time to get Model 3 production ramped up.

We don't know much about the semi, but Musk was obviously excited when he talked about it at a TED talk in April.

“It is a heavy duty, long range, semi-truck. So it has the highest weight capability and with long range. So essentially it’s meant to alleviate the heavy duty trucking loads. And this is something which people do not, today, think is possible. They think the truck doesn’t have enough power or it doesn’t have enough range. And then with those with the Tesla semi we want to show that no, an electric truck actually can out-torque any diesel semi and if you had a tug-of-war competition, the Tesla semi will tug the diesel semi uphill.”

This truck is more likely to be a true class 8 big rig, unlike the recent Cummins truck which is a class 7, built for 80,000 pound loads for long hauls.

Not only that, but the Tesla semi is apparently fun to drive.

“This will be a very spry truck... You can drive it around like a sports car.”

Elon had already taken the prototype for a test drive in a parking lot.

“There’s no gears. It’s like single speed.”

It will be pretty amazing if Tesla successfully dethrones diesel as the drivetrain of choice for a semi. We will tentatively find out in just over a month.
