Y’know, I can see why you would want to eliminate the current steering system to improve aerodynamics, but did you ever stop to think that the current steering system that everybody uses exists for a reason?

Have you ever driven a wheelloader? That is essentially what this is – a high speed wheelloader. Wheeloaders steer by articulation the chassis just like this. Conestoga wagons used that system. For low speed (<10 MPH) construction/mining this is A-OK. The problem is that a wheelloader is nearly impossible to steer a straight course with. No big deal at slow speeds, but a life-threatening problem at higher speeds.

The five-bar steering linkage used today (called Ackerman steering after the guy who designed it) makes the outside tire describe a much wider radius than the inside tire. The whole system is nearly self-centering.

This was a technological problem that was solved a hundred years ago and aerodynamics are not a good enough reason to throw it out.

Wagon steering was thrown out for a reason: It didn’t work.

Why doncha just stay with Ackerman steering (we know it works) and widen out the vehicle to 60" but don't widen the front wheels so far they would need to protrude out of the body work at full lock. This was used back in the 30s and 40s on some high-dollar European cars. It seemed to work OK. with a 60" wide car you have to make the tail 160 inches long. The additional length would give you room for a second seat in tandem, making for a much more commercially viable car. A nice VW TDI diesel transaxle gives you a very efficient drive train and most of the rough spots have been worked out of that.
