Many people probably know this concept car from 1970 exclusively as a model car. Matchbox issued this in 1971 in 1:65 scale under the internal abbreviation MB66 in orange. In 1975 they changed to red and between 1978 and 1985 there were various other colors on local markets. How many copies rolled into the toy boxes can no longer be traced. Nowadays there is a highly detailed 1\/43 scale collector’s model available from Spark. The original, on the other hand, was made only once – even if various color changes gave the impression that there had been several cars. As the headline already reveals, this is the Mazda RX500.<\/p>\n\n\n\n

Twin-chamber rotary engine with 250 hp<\/h3>\n\n\n\n

This study was presented in October 1970 at the Tokyo Motor Show. Mazda was celebrating its 50th anniversary and had designed this radical and angular wedge-shaped car for the occasion. Alongside the series models Luce, Cosmo and R100, the RX500 looked as if it had arrived from a distant future. The silhouette alone was enough to excite the public. In addition, however, there were butterfly doors opening forwards and upwards as well as a rotary engine hidden under further gullwing doors in the rear. At this point, Matchbox deviated from the prototype, by the way, because in the model car the engine compartment open in one piece to the rear. The internally christened ’10A’ twin-chamber engine produced 250 hp from a mere 982 cubic centimeters. This was achieved by revs of up to 15,000 rpm. Such high-revving concepts weren’t even available in motorsport at the time.<\/p>\n\n\n
