What's innovative about it? They say it's innovative (twice) but I can't see anything new?
RX-8 does have 2 doors (thankfully, as I wouldn't fancy the climb over the transmission tunnel!), the brake regeneration etc is going out onto other BMWs and MINIs, two tone body is done by smart.
I suppose the innovative thing is that it's got one door, but that's more of a safety issue than innovative and I wouldn't be telling people about it! But how many people will buy it and only realise when they get it home it's only got a door on one side?
