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.

New diesel engine for revised Meriva

VAUXHALL’s clever Meriva compact MPV is to benefit from a new 1.6-litre diesel engine. The quieter, smoother and more efficient engine replaces the aging 1.7-litre unit that had been in service across the Vauxhall, Chevrolet and other General Motors brands for many years. This is the second application for the new engine, following its debut in the much larger Zafira Tourer.
