No but it knows the diametrical relationship between the front and rear wheels, and since they have a different ratio you can exploit this. It also knows road speed vs GPS speed and calculates the speed shown in-dash (and i'd guess the torque curves) accordingly.
The sensors and system will slowly adapt to a different size front/rear.
A strapped down Bentley. Cool.In the suspension lowering (and raising) world with Bentleys, we called that putting on Clown Shoes
Because the torque curve is pre-calculated and fixed, the lightest, smallest diameter tires/wheels would give the best acceleration, up to the point where they start to slip.
When the car sells, I'll have a brand new set of wheels and tires to put back on it.While it could help it would be outclassed by other manufactures with performance sedans and sports cars that use transmissions. I get the you tesla owners like the simplicity and its fine for a non performance vehicle. But think about it, with that setup and low or high speed you are only using optimum power of one of the motors to accelerate as opposed to using both motors at full power if you had a second gear. There will be a second gear for true performance cars as well as trucks as proof by the rimac and nikola one. I mean its simple, use one motor down low and one up top or use both down low and up top with a second gear.
You don't want tall for best acceleration. You want a small diameter tire. The torque curves were designed for the 19" all season tires. To make use of any more grip, you have to go with a tire/wheel combination that has less rotating mass (moment of inertia) or is smaller in diameter than the 19" tire/wheel combination that comes stock.
I'm not sure there's a real need for a transmission for the vast majority of the driving cases for the S either... but I'd expect that if one were to be added, it would take the place of the single gear-reduction portion of the existing drive unit casing also housing the differential. I'd expect a 2 speed could be pretty compact, and not impinge too much on the surrounding space.
botox,
I found that Tesla's 21" option offered very little value. Instead, I took delivery with standard 19s and purchased some TSW Nurburgrings in 20" with Pilot Super Sports. The rims were 10lbs per corner less rotating mass along with the PSS' having more grip, better wear and costing less
BTW, the 20" option was a little over half Tesla's 21" option along with having the 19s in reserve.
Exactly the rimac has 4 motors and 4 gearboxes so it can have 4 wheel torque vectoring. Rimac can make a transmission, why can't tesla? Just because they failed when they were first attempting it? Ever heard of a power glide? 2 gears and very compact and used for launching cars with 3000+hp and equally crazy torque numbers. They cans be built to be strong, reliable, and compact.
