I think the viper engine is about the same size as a full punto =)
I think they both will improve with the alliance. Fiat needed doors into America and Chrysler needs the engineering work done with the small cars. Chrysler also needs the worldwide distribution outside the US.
Potentially, if the managers work together, they can create two of the strongest automotive companies out there. They both now will have the path, they just need to make something that people will really enjoy and afford, which I think between the two of them they can.
