Concept Car of the Week: Mazda RX500 (1970)

Developed by the Toyo Kogyo Company's advanced design and engineering team, the Mazda RX-500 was described as a ‘mobile test bed for high-speed safety'. Looking at its design, the team's childlike enthusiasm has shone through, resulting in a very cool concept.  From the rakish front to the wraparound windscreen and on to the bread van rear, everything communicates high-tech and ‘70's futurism while also channeling a little of the Star Wars X-Wing. Thanks to plastic body panels, the concept weighs only 850kg and is powered by a 491cc rotary engine delivering 247bhp fitted behind the cabin, in front of the rear axle.

And now we get a super-light MX5 that isn’t a concept but also can’t be bought for the road because it’s a track car – the Mazda MX-5 GT. MX-5 lovers the world over weep.
