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.

Students experiment with interactive window glass for GM

General Motors is thinking long term for its back-seat entertainment. It worked with students from the Future Lab at Bezalel Academy of Art and Design in Israel to develop apps that run on a car's rear side windows. The project, called Windows of Opportunity, was inspired by studies that say passengers often feel disconnected from their environments.

SEAT Leon X-Perience price & spec – costs from £24,385

The ‘Allroad’ SEAt Leon X-Perience goes on sale. SEAT hasn’t got round to building its first SUV, but the new SEAT Leon X-Perience is a half-way step – for SEAT and its customers – with added butchness and off-road pretensions in a high-riding estate car. SEAT has gone the usual ‘Allroad’ route for the X-Perience by fitting new bumpers, adding skid plates, extra plastic cladding and pumping up the ride height to give an estate that actually looks quite alright and, with 4WD and diff locks, can actually walk some of the walk.
