However, the improvements extend beyond the powertrain, as both cars receive a fully adaptable air suspension damping system. Developed in-house, it is said to constantly adapt to the road surface and driver behaviour, while causing the cars to descend to the ground when sailing to optimise aerodynamics.
Other minor changes include new wheel bearings and new tyre designs for certain variants, improving steering feel, driving quality and range. As a reward for those who purchased a Model S or X prior to upgrades, the company is offering a free Ludicrous Mode upgrade to existing owners who purchase a new Performance model.
In an unusual move, the company has reversed its relatively recent decision to eliminate variants from the Standard range by reintroducing them in both models.
The updated Teslas is going into production at the companys Fremont, California factory this week, with online orders now open. A spokesman for Tesla UK said that any of the new ordered models would be subject to a similar delivery lead time as outgoing variants.
