Tesla's upcoming all-electric heavy-duty truck.

‘Tesla Semi’ is an heavy-duty all-electric truck program at Tesla led by Jerome Guillen, Tesla’s former Model S Program Director and VP of Vehicle Engineering. Before joining Tesla, Guillen was an executive at Daimler where he successfully led the development of the Cascadia truck program (picture on the right).

The vehicle was first announced in CEO Elon Musk’s’ ‘Master Plan Part Deux’. Here’s the relevant part of the ‘Master Plan‘:

“In addition to consumer vehicles, there are two other types of electric vehicle needed: heavy-duty trucks and high passenger-density urban transport. Both are in the early stages of development at Tesla and should be ready for unveiling next year. We believe the Tesla Semi will deliver a substantial reduction in the cost of cargo transport, while increasing safety and making it really fun to operate.”

It was officially unveiled on November 16, 2017. Here are all the details.

Tesla Semi catches fire on I-880 with no crash, closes freeway for 10 hours

Firefighters spray foam on a burned Tesla Semi and trailer on I-880 in Hayward, California

A Tesla Semi caught fire on Interstate 880 in Hayward, California, on Tuesday evening, and there was no crash. The electric truck’s lithium-ion battery burned long enough to keep the southbound freeway closed for about 10 hours.

The driver got out unhurt. But a Class 8 electric truck catching fire on its own, in traffic, is something Tesla and its growing list of Semi customers need to explain.

Tesla Semi wins 2,500-truck order, doubling US electric Class 8 fleet

Tesla Semi drive

Tesla has been named the primary truck supplier for the largest electric Class 8 order in US history: 2,500 battery-electric trucks bought through a new shipper alliance called ZET SCALE.

The order on its own would nearly double the number of electric Class 8 trucks on US roads, and the alliance says it’s targeting more than 10,000 over time.

Tesla is going to operate public Megacharger sites at three electric truck depots it doesn’t own. Forum Mobility, one of the largest heavy-duty charging operators in the US, says Tesla will run public Megacharging at three of four new California depots it’s about to break ground on.

The move comes as Forum brings another 30 MW of heavy-duty charging online and sits on reservations for more than 330 Tesla Semis. It’s the clearest sign yet that Tesla’s Semi charging network is getting built through partners, not just Tesla-owned stations.

Tesla Semi slides on ice and impressively regains control

Tesla Semi sliding on ice

Tesla’s Semi program lead Dan Priestley shared a video of the electric truck holding its line on icy winter surfaces, sliding under control rather than skidding out of it.

The clip is a rare look at the Tesla Semi’s Vehicle Dynamics Control (VDC) system doing exactly what an electric drivetrain is supposed to do better than a diesel one: catch a heavy rig before it gets away from the driver.

Nikola founder and convicted fraudster attacks Tesla Semi with some decent points

Trevor Milton, the convicted fraudster who founded Nikola Motors, took to LinkedIn to attack Tesla Semi’s economics with a point-by-point takedown. Despite his near-total lack of credibility, a couple of his arguments actually hold up.

Milton, who was convicted of securities fraud for lying to investors about Nikola’s electric truck technology, posted a lengthy comment on a LinkedIn post about Tesla ramping Semi production, claiming he “knows EV trucking probably better than anyone.”
