Currently reading: Tesla updates Model S and X with longer range and new tech
More efficient drive unit, faster charging and chassis upgrades for largest Teslas, entering production this week

A series of upgrades have been issued for the Tesla Model S saloon and Tesla Model X SUV, including a range improvement of more than 10% for Long Range models. 

The American EV maker claims to have substantially upgraded the drive unit fitted to both Tesla models, introducing the “optimised permanent magnet synchronous reluctance motor” from the Tesla Model 3, and using silicon carbide in the unit’s electronics. Redesigned gearing, new bearings and improved cooling and lubrication boost all-round motor efficiency. 

The result is a claimed EPA cycle range of 370 miles for the top-spec Model S and 325 miles for the equivalent Tesla Model X. This is apparently achieved without any changes to the 100kWh battery pack in both cars. 

At the same time, Tesla claims to have improved power and torque “significantly” without quoting specific figures. Charging times have come down, too, with both cars capable of achieving 200kW on the latest ‘V3’ Superchargers and 145kW on the more common ‘V2’ Superchargers.

The upgrades extend beyond the powertrain, however, with both cars receiving a fully adaptive damping system for the air suspension. Developed in-house, it’s claimed to constantly adapt to the road surface and driver behaviour, while bringing the cars lower to the ground when cruising to optimise aerodynamics. 

More minor changes include new wheel bearings and new tyre designs for certain variants claimed to boost steering feel, ride quality and range. By way of recompense to those who purchased a Model S or X before the updates, the firm is offering a free Ludicrous Mode upgrade to existing owners buying a new Performance model. 

The updated Teslas are entering production at the firm’s factory in Fremont, California, this week, with online ordering open now. A Tesla UK spokesperson claimed that any of the new models ordered would be subject to a similar delivery wait time as the outgoing variants.

In theory, this all-electric luxury car looks a hit. So is it in practice?

Just great?

 Everything you need in a hundred thousand pound motor, oh please!, it’s a car 95% of us can’t afford, a car that’s supposed to be good for the environment, a car with a £30k interior, an interior that a mid range anything is better made, Tesla, the automotive equivalent of Donald Trump....

Sorry but

Its a 7 year old design, this shouldnt have been an upgrade, it should have the announcment or reveal of the mk2, there is only so much you can do when your interior consists of an over sized Ipad.. Still it keeps the fanboys happy..

Achievable range!

The operative word here is EPA. Generally, EPA figures are achievable and are about 15 percent tighter than WLTP i.e. Audi E-Tron manages 204 on EPA versus 240 on WLTP i.e. the updated Model S should do 430 or over on WLTP.
