Beginning today, Tesla's Model S and Model X now come with an all-new drivetrain design that increases each vehicle’s range substantially, achieving 370 miles and 325 miles on the EPA cycle for Model S and Model X Long Range, respectively.

Using the same 100 kWh battery pack, these design and architecture updates will allow drivers to travel farther than ever before, charging less frequently and getting more range out of every dollar spent on charging.

Tesla is also introducing a new adaptive suspension system for Model S and Model X, along with a few other improvements for the best range, acceleration, and ride comfort ever, plus a Ludicrous Mode upgrade for our most loyal customers. Here’s what’s new:

More Efficient Design

All Model S and X vehicles now benefit from Tesla’s latest generation of drive unit technology, which combines an optimized permanent magnet synchronous reluctance motor, silicon carbide power electronics, and improved lubrication, cooling, bearings, and gear designs to achieve greater than 93% efficiency. Pairing a permanent magnet motor in the front with an induction motor in the rear enables unparalleled range and performance at all times. The net effect is a more than 10% improvement in range, with efficiency improvements in both directions as energy flows out of the battery during acceleration and back into the battery through regenerative braking. In addition to adding range, power and torque increases significantly across all Model S and Model X variants, improving 0-60 mph times for our Long Range and Standard Range models.

Faster Charging

Paired with the new more efficient drivetrain design, Model S and Model X are now capable of achieving 200 kW on V3 Superchargers and 145 kW on V2 Superchargers. Together, these improvements enable Tesla's customers to recharge their miles 50% faster, according to the company.

Fully Adaptive Suspension

Tesla has also upgraded the air suspension system for Model S and Model X with fully-adaptive damping, giving it an ultra-cushioned feel when cruising on the highway or using Autopilot, and a "confidence during dynamic driving." Unlike other manufacturers, Tesla's suspension software is developed in-house, using a predictive model to anticipate how the damping will need to be adjusted based on the road, speed, and other vehicle and driver inputs. The system constantly adapts by sensing the road and adjusting for driver behavior, automatically softening for more pronounced road inputs and firming for aggressive driving. Tesla has also improved the leveling of the system while cruising, keeping the car low to optimize aerodynamic drag. As with all of Tesla’s in-house software, the adaptive suspension can receive over-the-air updates.

Constant Refinement

To complement these changes, Tesla has also re-engineered several other components of Model S and Model X. These updates include new wheel bearings and a few new tire designs for certain variants to improve range, ride, and steering.

In addition to Tesla's Long Range and Performance variants, the company is also re-introducing a lower entry price for Model S and Model X by bringing back the Standard Range option, now available for an even greater value with the new drivetrain and suspension updates. Tesla also wants to emphasize the critical impact each of the early Tesla owners has had on advancing our mission, so all existing Model S and Model X owners who wish to purchase a new Model S or Model X Performance car will get the Ludicrous Mode upgrade, a $20,000 value, at no additional charge.

These changes will go into production at our factory in Fremont, California this week, and can be ordered today at Tesla.com.
