Tesla has provided Model 3 owners with a new over-the-air update which is said to increase the on-track agility of their car and - if an accompanying video is anything to go by - provide them with the means to get really quite sideways on its surfeit of usable torque. Using the car's existing hardware, the new software essentially ups the reactivity of the the car's twin-motor, all-wheel drive powertrain, which, as you'll know, is really rather reactive to start with.
In Track Mode, if the driver asks for more steering angle while accelerating hard - aka they want to slide - the car can shuffle more drive to the rear motor, making the Model 3 temporarily rear-wheel drive. Unlike the on-off style switch of the BMW M5's all-wheel drive system, the Model 3 chooses to control the distribution of torque at the front and rear constantly, so after you've straightened up from a drift drive is reintroduced to the front axle.
Additionally, the brakes also come into play more often through the bends, enhancing the 3's ability to push more torque to the loaded side by applying even more braking force on the inside. This obviously simulates the effects of a limited-slip diff and is therefore primarily an aid to traction - unless, of course, you tell the car you want to get sideways again. Then it abandons this plan entirely.
Also turned up in Track Mode is the car's regenerative braking capability, as Tesla reckons you'll want maximum deceleration on track when the anchors are on. Thus you get improved stopping performance, and the car claws back as much battery life as possible (handy when it will be evaporating at huge rate from everywhere else).
Of course, electric powertrains have a habit of getting quite hot when you ask so much from them. So to preventing your Model 3 going into meltdown, Tesla's new software update enables the cooling systems to work overtime. Tesla said the system will also work for longer when the car's parked to bring the temperatures lower than it normally would, leaving you with more time before things start to overheat. In line with this, Track Mode also allows the powertrain to get hotter than normal. Cue "never been in Track Mode" lines on used Model 3 adverts...
