A 1956 Cessna 310 and a Toyota Van, together, in the 24 Hours of LeMons.

They went amphibious too!

The problem with using an airplane as a ground vehicle - is the wheels and the ground. The ground very much changes the aerodynamics, because the ground constricts the air flow under the car; and the wheels have to be exposed at least enough for the suspension to work.

I'll also mention that Mercedes did a study comparing single form cars to cars with outboard wheels, and they found that the latter was inherently higher drag. Air flows around the wheels interacts with the air that is being pushed out and around the main body, and this will always be worse. Also, where the suspension (or its covering) intersects with the wheels and the main body increases the drag.

Here's my attempt to ameliorate that condition. Axle line is forward of max camber with a wide track, the suspension is in-wheel ala Edison2, and the suspension beam is filleted. It shoulda/coulda have been airfoiled like this design from the mid-90s.

But anyway, a few months ago while I was looking for info about those Jabiru light-sport aircraft with a fiberglass monocoque I caught me looking at its aerodynamics and low weight. Even though a conventional automobile driveline would add some weight penalty, it still seems to be a good source of inspiration for a 4-seater aerodynamic prototype.

With hub motors and conformable batteries? Could work.

I was actually considering a more conservative driveline, but it seems like a set of hub-motors would be the least disruptive to the aerodynamics.

I was thinking of the elimination of hard points; with the motors carried on the suspension.
