First Look Under A Tesla Model 3 Performance – Video

AUG 5 2018 BY MARK KANE 8

The Tesla Model 3 Performance is the dual motor, all-wheel drive version of Model 3 Long Range

Ingineerix recently just put the P3D up on the lift and checked out how it looks from the bottom, without motor covers.

The brief presentation includes powertrain and suspension. There aren’t a whole lot of changes to the car, as it was designed from the beginning to just simply add front powertrain (motor, inverter and single-speed transmission with connections).

With two motors, the Model 3 Performance is able to go 0-60 mph in less than 3.5 seconds.

“Here we get our first P3D (Performance AWD) up on the lift and remove her covers for a quick look at the motors and suspension. This model does not have the upgraded (red) braking system. The suspension and springs have the same part # as compared to my RWD. Also, the same (physical) rear motor, though with a different part number (higher-spec 800A inverter vs. 500A). The front motor is physically smaller, but appears to use the same inverter assembly. The only suspension differences I could note are both stabilizers and the front strut is different (has a half-shaft pass-through). Same springs front and rear. The cooling system hits the PCS, then the Rear Inverter, Rear oil cooler, Front Inverter, Front Oil, then back to the reservoir.”

If it is an inductance motor then doesn’t seem possible that it’s the same inverter as in the rear.

Why do you think this? An inverter is basically a couple of current sensors, a rotor position sensor, three phase drivers, and and a computer. The software might be a bit different, but there is no particular reason to change the hardware.

You make it sound rather simple. It’s not.

Here’s a photo of the Model S inverter, including the 28 IGBTs:

The point was not that it’s simple, but rather that there are no conceptual differences in what the inverter does between three-phase induction motors and three-phase IPM motors…

this what I would expect without the 5k brake/wheel/suspension package package

It will be a big profit maker for Tesla. Easy to see why they are trying to generate extra demand for the performance model.

Huge margin, I would think for the 70K+ model!.

We’d expect fewer items, on the P3D w/o the Performance package, but some things are shared right through the tricked out, all-inclusive, car, such as the spring/damp rates. This was indicated in the Road and Track review.

These cars are great because the roll center is so low that the springs and dampers don’t need to be stiffened up so much, for the transient “rocking” that BMW and other high-mounted front-engine cars suffer.

The strut “pass-through” is simply the bend in the front AWD strut, to allow a drive-shaft to pass into the front knuckle. Having a stabilizer bar accommodate this does not make for a firmer bar. Sticking a caliper on the bar, itself, is what Ingineer should try. Any millimeter difference in circumference would be good to know.
