The new Tesla Model S Long Range Plus has become the first electric car to be certified by the EPA to drive more than 400 miles on a single charge.
Starting this week, all North American Model S Long Range Plus vehicles have an official EPA-rated range of 402 miles (647 km), representing a nearly 20% increase in range when compared to a 2019 Model S 100D with the same battery pack design.
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. These changes went into production earlier this year when the Palo Alto-based company first started manufacturing Model S Long Range Plus at the factory in Fremont, California. All Model S Long Range Plus vehicles will receive the new 402-mile rating.
The Tesla Model S Long Range Plus has also recently received a price reduction of $5,000. Paired with these range improvements and gains in efficiency, customers now receive more value than ever when purchasing a new Tesla.
Here’s what’s new:
Significant Mass Reduction
Mass is the enemy of both efficiency and performance, and minimizing the weight of every component is an ongoing goal for our design and engineering teams. Several lessons from the engineering design and manufacturing of Model 3 and Model Y have now been carried over to Model S and Model X. This has unlocked new areas of mass reduction while maintaining the premium feel and performance of both vehicles. Additional weight savings have also been achieved through the standardization of Tesla’s in-house seat manufacturing and lighter weight materials used in the battery pack and drive units.
New “Tempest” Aero Wheels and Tires
Tesla’s newest 8.5 inch-wide aero wheels reduce aerodynamic drag compared to the previous wheels on Model S Long Range, and when paired with a new custom tire specifically engineered to reduce rolling resistance, add a 2% improvement to overall range.
Increased Drive Unit Efficiency
In the rear AC-induction drive unit, we replaced the mechanical oil pump with an electric oil pump that optimizes lubrication independent of vehicle speed to reduce friction. Further improvements to the gearbox in our front permanent magnet synchronous reluctance motors shared with Model 3 and Model Y have resulted in a further increase of 2% more range while driving on the highway.
Maximizing Regenerative Braking
Tesla’s newest drive feature, HOLD, blends the motor’s regenerative braking with physical brakes to bring cars to a stop by easing off of the accelerator pedal. To bring the car to a stop smoothly, regenerative braking now works at a lower speed and deceleration rate, sending more energy back to the battery pack while simultaneously enabling a driving experience like no other car.
Continued Investment in Supercharging
The freedom to travel anywhere is enabled by both range and charging, and the Supercharger Network now encompasses over 17,000 Superchargers worldwide. Tesla has deployed V3 Supercharging on three continents, enabling up to a 50% decrease in charging times compared to V2 technology. Tesla owners can travel incredible distances – from the Everglades to Vancouver, the Arctic Circle of Norway to southern Portugal, Hong Kong to Harbin, China – all for a fraction of the cost of gasoline. Put simply, families spend less time than ever charging.
While each of these changes are relatively small in individual impact, Tesla’s unique ability to introduce them into active manufacturing lines enables significant gains in efficiency, range, and overall value when combined.
