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.

Autoweek in review: What you might have missed

Lexus CT 200h: The emissions

Teh Lexus CT 200h has emissions of just 96g/km We have to go with the flow on this because, although we have no faith in the assertion that man is responsible for climate change, for as long as Governments penalise and promote cars based on the emissions of CO2 from their tailpipe (I know, it’s barking) we have to accept that car makers will respond to that stick and carrot. Which is why we see a raft of car makers churning out ‘Eco’ cars with a 99g/km emissions figure, as sub-100g/km of CO2 emissions is the Holy Grail for maximising tax effiecencies. Of course, Lexus has gone a step further and seem intent on producing only hybrid cars as soon as possible.
