I sure nothing was left on the table to make it go as cleanly through the air as possible, but ultimate top speed was not a top priority. I guess my point was, when you have a car to go FAST in a relatively straight line, you have something like a Veron, where turning / downforce is not its strong suit.
I thought (perhaps incorrectly) that the whole point of the NGT tapered fuselage was to reduce drag--enormously. If that is the case, wouldn't the increased down force provided by diffuser and active aero be somewhat offset, allowing a relatively high top speed?
Well but the fact the wing can get out of the way, would increase its top speed (vs a fixed wing).
As for ride height, from the initial press release "The state-of-the-art chassis is suspended by an active racing-style torsion bar and pushrod suspension, with adjustable ride height."
I think the only active aero is the wing that will raise up and provide more down force when needed and than can flip up to be an air brake, neither one of those functions will reduce the drag / increase speed. If the car can lower it's self that would increase the speed.
