 Toyopet Corona Hardtop RT50
image
This was a passenger vehicle with coupe styling, and the first Japanese hardtop that featured no center pillar.
The RT50 had a well-balanced structure featuring stiffened front pillars, roof side rails and roof side frame, which served to prevent any loss in bending-torsion rigidity. It was also equipped with the first rear seats on a Japanese vehicle that could be folded down to create a luggage space.
The RT50 was 40 kg lighter than its base version (the RT40). It also had a better hill-climbing performance, top speed, fuel consumption and acceleration as a result of its lower weight, height and wind resistance. This latter performance was a product of reducing the angles of the front and rear windows.
The RT50 won a second category special commendation at the 15th Mainichi Industrial Design Awards in 1966.
