The Rover Scarab was a convertible four seater intended to sell at £85, and had a V twin engine of only 839 cc, which was rear mounted.
Despite the engine position, the Scarab had a conventional (dummy) radiator grille at the front.
Some other 1930s rear engined cars had a down-curved grille-less front.
These included the Porsche Type 12 prototype, the Mercedes-Benz 120 test car, and the subsequent 130 / 150 / 170 H, the Tatra V570 prototype, T77, 77A, T87 and T97 and of course the KdF-Wagen (later better known as the Volkswagen Beetle; see Volkswagen controversy).
