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.

Land Rover Defender Challenge by Bowler – the Defender goes rallying

The Land Rover Defender goes rallying (pictured) with Bowler modifications The venerable Land Rover Defender – now reaching the end of its shelf life – may not seem the perfect rally car. But a Defender tweaked and fettled with some Bowler Fairy Dust is another matter, and that’s exactly what’s happening with a new, one-make Defender Challenge by Bowler – and backed by Land Rover – which is aiming to put up to fifteen Defenders in to UK forest stage rallies and hill rallies in 2014. The Defender in question is a Defender 90 Hard Top with the usual 2.2 litre diesel, but sorted by Bowler to deliver 170bhp and 323lb/ft of torque (up from the regular 122bhp/266lb/ft) with a standard six-speed manual ‘box, MSA roll cage, fire extinguisher and Khumo tyres.
