It's an excellent design. Its very low seating position allows a low roofline for smaller frontal area, and more importantly a low center of mass which allows narrow track width. The driver's pelvis ought to be 8" off the ground for good aerodynamics.
The VW L1 has a good but not great drag coefficient of 0.195, but due to its tiny frontal area, its 0.2mē of drag area is far better than that of most aerodynamic concept cars.
Would raising the body away from the ground and moving the wheels farther apart reduce CdA or increase it? Well, the VW L1 is slightly more aerodynamic than the Aptera, so I'd say it depends on your implementation.
