My current vehicle is a Jeep Grand Cherokee. How will the driver's cockpit compare? Access. Headroom. Legroom.
It's hard to speculate until the MX is revealed. There are a few fair points that may or may not end up making a difference:
1) The Model X is based on the Model S platform, so it's pretty safe to say the MX will be 6+ inches longer than the Jeep. That will probably translate into a little more space up front.
2) The Model X will likely sit lower than the Jeep, so it will feel different getting in/out. It won't be as low as a car, but probably on the low side for the class.
3) Overall I'd expect less headroom. The MX is looking like it will be more aerodynamic than most (all) SUV type vehicles. I have no idea if this will actually be true or how much of a difference it will make.
@sg021 +1 on all points
Headroom maybe a killer for those of us that are actually 6'1" or more.
But, I doubt Elon is "short sighted" on that issue.
Franz von Holzhausen looks to be at least 6'-4" tall. He seemed to fit in the driver's seat of the Model X prototype just fine.
The Model S, at least with the Panoramic Roof, has reasonably good headroom. See http://www.teslamotors.com/forum/forums/tall-people
I expect the Model X to have a bit more headroom than the Model S, but we won't know for sure until we see a production vehicle.
I think the headroom of the X will be almost identical to the S. Two reasons
a) Tesla must have a low drag. Frontal cross section area is a component of that.
b) The X is being geared more toward women. Elon has stated as much. Hence the focus will not be on more headroom.
I believe Tesla has settled on the optimal headroom required for maximum sales. It will not change.
When I test drove the S, I found the seat belt height was not adjustable and the seat did not slide back for entering. I hope these options are available on the X.
