By track you mean drag strip because mass and high C of G are going to make this thing difficult to corner/handle.

Why would it have a high centre of gravity? Wouldn't the battery pack be most of the mass and live right at the bottom?

The model S has a ground clearance of 6 inches and a center of gravity of 17.5 inches. This thing has a ground clearance of 16 inches. Assuming similar weight distribution, that's a center of gravity of 27.5 inches. Compare that with:

BMW 3 series: 20 inches Subaru BRZ: 18.1 inches Porsche 911 GT3: 17.9 inches

>This thing has a ground clearance of 16 inches. up to 16 inches, which may (or may not) indicate dynamic suspension

It has a ground clearance of 16 inches with the suspension at max height. When it lowered itself for the tailgate ramp, it was probably closer to 10 inches off the ground.

The triple motor also has a double stacked battery, so the center of mass is not going to be much further up than the battery is.

Based on the stated ranges of 250, 300 and 500miles (!), I would guess those battery sizes are 75, 100 and 150kWh. I hope the upcoming triple motor model S, will get that 150 battery pack next summer. That would mean 600miles of range for the new model S.

The 500 mile range is 200kWh I believe. There’s a penalty because they are literally stacking a second pack. Probably not enough room to do that in an S, but I’m sure by then the S will see other upgrades.
