Tesla Model S reaches 400-mile range milestone

Tesla Model S

In a post on the Tesla blog yesterday, the company said, "Starting today, all North American Model S Long Range Plus vehicles have an official EPA-rated range of 402 miles, representing a almost 20% increase in range when compared to a 2019 Model S 100D with the same battery pack design". With an average fuel economy of 25.1 mpg, according to the EPA for 2018 models, and a rough estimate of a 15-gallon tank (with wide variances between compact cars and pickup trucks), a gas vehicle would travel about 375 miles before needing to refill. The EPA refuted that and claimed that the latest 391-mile result was accurate.

So as of February this year, any Model S Long Range Plus vehicle should achieve that range.

"This significant achievement reflects Tesla's obsession with efficiency and energy frugality, and is realized through several changes, both iterative and transformational, in core hardware and system architecture development by the Tesla engineering, design and production teams", the company said in a statement. Despite using the same battery pack design, the automaker has revised several facets of the Model S to maximize efficiency, carrying over a number of lessons it has learned since the vehicle first launched in 2012.

Likewise, new lightweight and aerodynamic wheels have also helped increase range by as much as 2 percent according to the company.

Efficiency gains have been made in the drive unit by replacing the mechanical oil pump with an electric one that lubricates regardless of vehicle speed, and a two percent increase in range has been achieved though tweaks to the gearbox in the front motors.

Model S Long Range Plus has also recently received a price reduction of $5,000. Lucid CEO Rawlinson-who, perhaps not so coincidentally was the original Model S chief engineer-has claimed that the Air will be able to accomplish not just an EPA range of more than 400 miles but 400 miles at true highway speeds.

With a bulletproof body and 500-mile battery-powered range, Tesla's electric pickup isn't like every other truck. This has been certified by EPA-rated (US Environment Protection Agency).
