Daihatsu Copen

Daihatsu CopenLaunched in 2002, the Copen isn't Daihatsu's newest model, but it's certainly the sportiest. The two-seat roadster goes from zero to 60 mph in a respectable 11.7 seconds, while averaging 44.1 mpg of gasoline. Its electric retractable hardtop goes up or down in 20 seconds. The cost? $13,700 to $16,000. In some overseas markets—but not the U.S.—a larger 87-horsepower, 1.3-liter engine version is also available.

Review: I would like a two seat sport mini. Sixty horsepower would propel a 600 pound vehicle nicely. The 600 pound weight could be achieved with large diameter narrow motorcycle spoke wheels and high pressure tires would improve fuel economy. Mylar skin is an option if the mylar were easily replaced when torn. Two front drive wheels are essential, but one rear drive wheel is adequate and would save costs. I've seen 1200cc two cylinder Harley engines rated for 9,000rpm. A 600cc engine should be capable of 12,000rpm. A continuously variable transmission or six speed motorcycle transmission bakes the cake. A couple of chrome upright exhaust stacks could add a cool factor. One front seat wide enough for three with indents for the main passengers is plenty.
