Tesla has revealed new versions of its Model S electric sedan and Model X SUV. Both cars look familiar on the outside, but have new interiors and increased performance.

The biggest talking point of both new cars is the interior, which features a yoke-style steering wheel and has no conventional stalks for the wipers and turn signals. The gear selector has also been removed, with all controls replaced by touch-sensitive buttons on the wheel itself. A wheel of this shape was first shown off by Tesla on the prototype of its upcoming Roadster.

On the cars having no stalks or gear selector on the steering column, Tesla boss Elon Musk tweeted: "No more stalks. Car guesses drive direction based on what obstacles it sees, context & nav map. You can override on touchscreen."

On closer inspection, the two scroll wheels of the steering wheel are surrounded by what appear to be touch-sensitive buttons for the turn signals, high beam, horn, screen wash and voice control. The Porsche Taycan has similar touch controls, in that case with haptic feedback, around its instrument cluster. Turn signals appear on the steering wheel of some other cars too, mostly notably from Ferrari, but in that case they are physical buttons that can be located and operated by feel. We will be interested to see how Tesla's touch system works in the real world.

Another major change to the interiors of both the Model S and X is the touchscreen display. This has changed from portrait to landscape orientation, copying that of the Model 3 and Model Y. The new screen measures 17 inches and has a resolution of 2200 x 1300.

Both cars have also gained a second display, situated between the front seats and for the use of rear passengers. This screen measures eight inches and can be used to view video content and play games by connecting a wireless controller to the Tesla Arcade system. It also gives rear passengers control of some of the car's systems.

Tesla says its new gaming computer has up to 10 teraflops of processing power. To provide some context, this is almost on par with the 10.28 teraflops of the PlayStation 5 and the 12 teraflops of the Xbox Series X. Musk tweeted to say the new cars can play the CyberPunk 2077 video game, and added that the system has more storage than the 32GB of previous Teslas, and it is "easily upgradable".

Also new is the sound system, which now has 22 speakers and 960 watts of power. New microphones enable active noise cancelling, where the monotonous drone of wind and tire noise is dialed down in the same way headphones create artificial silence in an airplane cabin.

Although there aren't many photos of the new interior just yet, Tesla's website says the new cars offer wireless and USB-C fast charging for every passenger. The updated interiors also benefit from a full-length tinted glass roof, triple-zone air conditioning, heated seats for every passenger and ventilated seats in the front, a HEPA air filtration system and ambient lighting.
