    Well, about time. Yes, the supercar-shaming, instant-torque jowl-flapping acceleration the Model S in Ludicrous mode delivers is one hell of a party trick. But we like going round corners quickly, too, and the S and X are frankly a bit… lumpen.

    So Tesla’s engineers have been beavering away on vectoring the dual motors’ torque and using brake force to sharpen the Model 3’s cornering. It’s nothing new, but what is interesting is that they’ve developed their own Vehicle Dynamics Controller, and all the software is in-house. Virtually every other car maker uses systems developed by a tier one supplier, and then tweaks the software accordingly. Even Ferrari. Tesla didn’t think it could achieve the level of integration it wanted, so it’s a lone wolf. Well if anyone can write their own code, it’s these guys, right?
    . . .
    Delve into the touchscreen menus and engage Track Mode. That’s it. The VDC monitors all driver inputs and the vehicle’s state, and divvies up the torque front to rear. As with any fast car, it takes time to dial into it, and the slip angles are in direct proportion to the size of your cojones, but it’s worth reiterating: Track Mode allows you to do it. Give it the berries on the way out of one corner and into another, and yep, we’re sideways. On the next run we’re drifting. Towards the end, you can even get it rotating with a Scandinavian flick. Now that I did not expect…

    Track Mode also increases the amount of regenerative braking. Tesla says it improves the endurance of the system, sends more energy back into the battery, and helps it unleash the maximum amount of power. The VDC also uses it to temper rotation when you come off the brake pedal.

    Sounds like a well balanced car with attention to cooling. Time to get it to Nuremberg.
