Whisper today(unconfirmed)its going to use the 1.3MJ engine,a true FIAT/FORD hybrid.Also heard Fiat are going to 'pair' up with other manufacturers aswell in the near future.
Really nice well thought out car a standard Ka handlkes nice its just theyre underpowered considering theyre 1.3 which is why i didnt have one that one is spot on and if nothing else you got to appreciate the effort that has gone into it
