Audi working with Mazda on Wankel for A1 e-Tron?

The Audi A1 e-Tron could be getting a Mazda Wankel Last year at the Geneva Motor Show, Audi showed us another in its seemingly endless line of fantasy e-Tron cars. But instead of being a pointless supercar with a pile of batteries bolted underneath to wreck the handling with all their weight – for the three feet you can actually drive with your foot to the floor before you run out of juice – this e-Tron was a different beast altogether. Not only was the Geneva 2010 e-Tron a properly sensible city car – the Audi A1 - but it came with a range extender so you could actually use this Audi A1 e-Tron beyond the confines of its electric charge.

Mazda wins 2008 LA Design Challenge

The Mazda Kaan concept has won the fifth annual LA Design Challenge competition, part of the Design Los Angeles automobile designer's conference. The award was presented during the second press day of the 2008 Los Angeles Auto Show, following a designers' luncheon and keynote speech by Daniel Simon, visionary futurist and author of Cosmic Motors. As we reported last month, nine local Southern California design studios entered the competition to envisage how motor sport vehicles might be in the year 2025, answering the theme ‘Motorsports 2025'.

Volkswagen XL1 Super Efficient Vehicle (SEV) spy video

Volkswagen XL1 caught on video The Volkswagen XL1 – a super efficient diesel hybrid – caught on video winter testing and undisguised. The VW XL1 arrived at the Qatar Motor Show in 2011, a two-seater diesel-electric hybrid with a design that looks like it came from a 1920s view of the future, and claims of a gazillion miles to the gallon. At the time VW debuted the XL1 we reckoned there was as much chance of it going in to production as McLaren’s latest Formula One car making it in to a showroom, and that the XL1 was just a test bed for all the future tech that might just find its way in to Volkswagen’s road cars.
