Acura is a division of Honda. also, Acura doesn't exist in japan, and any overlapping cars are Hondas. Honda was going to introduce the Acura brand in japan later this year, but have pushed it back until at least 2010.
Hmm, may turn out to be a nice car. But if this thing comes into production, they must NOT use the NSX name. They should use something else, because the NSX is remember for its MR layout and supercar shape, not a 350z look-a-like.
