Those side scoops seem to be the only source for cooling the air-cooled engine.
Compare to a Type-2 wagon.
OLD PARKED CARS: 1970 Volkswagen 1500 Squareback Wagon.
I do not think it would have a cooling problem after all (white car, not orange car).
Looks to be fairly aerodynamic outside of vortexes forming at the rear corners.
Gotta love those old VW Beetle based kit cars.
