A new video of a Tesla Semi prototype showing off its acceleration has sent EV-diehards into a frenzy.
The truck sounds unlike any other you’ve likely heard on the road before; instead of a roaring engine, the big rig lets out the kind of quiet ‘vroom’ you might expect to hear from a sports car.
Tesla’s electric truck prototype was spotted outside the firm’s office in Draper, Utah earlier this month.
The video, shared on Reddit, shows the prototype truck accelerating with a trailer attached.
Viewers pointed out that it sounds like anything but a semi-truck, with some instead comparing it to a spaceship or a moped.
Tesla claims the vehicle can hit 60 miles per hour in five seconds without cargo, and 20 seconds towing a full load.
The Tesla Semi is said to be capable of traveling 500 miles on a charge when moving at highway speed with its maximum weight load, 80,000 pounds.
Diesel trucks, on the other hand, can go about 1,000 miles on a tank of fuel.
Musk first unveiled the electric Semi at an event last November, during which he rode one into an airport hangar outside of Los Angeles.
They’re expected to roll out next year – but already, there have been several major orders, including PepsiCo, UPS, and Budweiser-maker Anheuser-Busch.
In the months since, several videos of the prototypes testing on the road have surfaced.
Earlier this year, Elon Musk teased a new ‘Mad Max’ mode that he says will arrive with the all-electric Semi.
The Tesla boss shared a photo showing various Autopilot settings, including a Mad Max option.
The comments were prompted by a tweet from another user, who jokingly shared an image from the 2015 action film Mad Max: Fury Road, where a Semi had been photoshopped alongside other vehicles from the movie.
Mad Max mode, included in Autopilot’s ‘blind spot threshold’ settings, would allow Semis to make more aggressive lane changes.
That means the Semi would require less room between it and the car in front of it when making a lane change.
Along with Mad Max, other settings include ‘Standard’ and ‘Autopilot.’
Musk initially shared the photoshopped image with the caption ‘Tesla Semi Truck in Mad Max Mode.’
But before anyone could assume he was joking, he followed that tweet by adding: ‘It’s real’, with the screenshot of the vehicle dashboard.
It’s unclear if Mad Max mode will actually make it past development on the vehicle, however.
