The fun factor should definitely be a bonus. We've had the redesigned Yaris sedan for over a year now, and I see one crashed every month or so due to over-exuberance on the part of the owner.
Buyers
have embraced these cars in the past. The Toyota Corolla, the Honda Civic and other Japanese small cars actually forced US makers to make a stab at competing in the small car market. I think the question now is: How small are American buyers willing to go? And
how many will make the jump?
I think everything hinges on the success of the Fit. It's the one subcompact that may actually change people's perceptions on the available space and utility of these vehicles. The Yaris has never been able to convince buyers (much too small inside). The Aveo sells merely because there's almost nothing cheaper. Smarts are just too small for the price and too cramped to make any sense. Sure they get great mileage, but they only carry two people and a paper bag.
The Colt is nice, and I hope it does well enough in the US to help in Mitsubishi's recovery. Hyundai/Kia have yet to bring their Getz/Picanto to the US. The Picanto is dirt cheap basic transportation on four wheels, and it is the cheapest car to own and maintain, anywhere. You could pick one up for a month's paycheck. The only problem is bringing it up to US crash specs.
It's only recently that the Honda Fit has rewritten the book on interior space in subcompacts and super-minis. While the Fit has as much space as older Civics and Accords, it also weighs about as much as an older Civic (2200 lbs or so), so it really isn't that tiny. I think the revolutionary thing about it is that it manages to make such a small chassis stiff enough to meet stringent new safety laws. That's a definite plus in this day and age, when even "compacts" are pushing close to three thousand pounds.
But I expect the larger size will actually help the sales of compacts in the US, as many buyers move down a notch in size and price and find that the new "compacts" actually drive like midsized cars of a decade ago, but with better fuel mileage.
