Tesla Semi: What Is The Tesla Semi’S Top Speed?
CEO Elon Musk noted the Tesla Semi will be able to reach freeway speeds in around 20 seconds when fully loaded, nowhere near the speeds of an ordinary Tesla such as a Model 3, but much quicker than the average diesel-powered truck. Without the trailer, Elon Musk said the Tesla electric Semi program could go from 0-62 miles per hour in five seconds thanks to the 4 separate Model 3 EV engines.
The Tesla electric Semi trucks would also comfortably reach 65 mph (104 km/h), while diesel trucks would reach just 45 mph (72 km/h) on average.
Without the trailer attached, Tesla says, its next large-scale vehicle will be capable of reaching 60 mph in five blazing seconds, the company said in 2017, when it revealed the truck. In numbers, that means a crazy 0-62-mph time in five seconds while it is empty, something Tesla says is three times quicker than what comparable diesel trucks can accomplish.
Tesla says that this trucks performance is much better than the equivalent diesel, which is able to hit just 45 mph while driving on a 5% grade.
More importantly, its Semi will go the full five % grade at a consistent 65mph, while a diesel truck will top out at 45mph at five percent. Elon Musk says that the Semi would still outperform the diesel truck in terms of performance with only two independent engines operating.
Musk said during Semis debut that his fully-loaded heavy truck, with an overall mass of 80,000 pounds, was able to keep its top speed at 65 miles per hour over 5 percent uphill grades.
His Semi could also hit 60 mph fully loaded at the vehicles top gross weight of 80,000 pounds in 20 seconds. While Tesla does not indicate power output, the Tesla website says that its semi-electric trucks have a range of 300 miles (482 kilometers) or 500 miles (805 kilometers).
Teslas semi-electric four-motor truck is expected to be priced at $150,000 for 300-mile range option and $180,000 for 500-mile range option.
Tesla originally announced the Tesla Semi will have 500 miles (805 km) of range when fully charged, and that it will be able to drive for 400 miles (640 km) on a single charge of 80 percent within 30 minutes using the Tesla Megacharger solar-powered charging station.
Tesla says that its all-electric drivetrain would provide over 500 miles of range on a charge, whereas it tows 80,000 pounds, is much easier to maintain, and exceeds conventional semi trucks in performance and safety — all while delivering lower operating costs.
Performance-wise, the infinite torque from the electric motors will enable a Tesla Semi to reach 60 miles per hour in only five seconds with no trailer, and in 20 seconds with full 80,000-pound loads. The Tesla is not as much a top-speed contender as other Semis on this list, but it is certainly a contender for other trucks acceleration times under load.
