Active Air Suspension & Range

Active Air Suspension & Range

My understanding is that The Model S has about 6 inches of road clearance. With Active Air Suspension it can be raised to about 7 inches for rough roads, driveways, etc. Since the clearance can be lowered to about 5 inches for higher speed freeway travel, does anyone know if we can expect measurable range extension with the lowest road clearance? I expect most of us will still be driving at average freeway speeds of 70 mph more or less. I was doing about 72 mph on Highway 280 near Woodside, Ca yesterday, and a Beautiful Gray Model S passed me like I was standing still. I presume he had Active Air.

Yes, he had active air. No Model S's produced/delivered this far have been built without it.

correction: "thus far..."

Yeah, since no standard suspension cars have been built yet, the real question is whether standard suspension will reduce range noticeably.

Or increase it: remember, the system IS a power drain afterall. We just don't know how much.

Active air is also heavier, perhaps the standard suspension will increase range...

Considering some posters have noted that an average complement of passengers hasn't noticeably affected their range I doubt the air suspension's extra heft would make a difference.
