VEHICLE/EQUIPMENT INTRODUCTION:
The Daihatsu Copen was a delightful two-seater convertible kei car produced from 2002 through 2012 by the Japanese automaker Daihatsu, then a subsidiary of Toyota. Designed with an innovative electro-hydraulically operated retractable hardtop that stowed neatly behind the seats in approximately 20 seconds, the Copen combined the open-air enjoyment of a roadster with the practical security of a metal roof. Its name derives from COupe and oPEN, reflecting its dual nature as both coupe and convertible. Built on the same platform as the Daihatsu Mira and Max kei cars, the Copen featured a turbocharged 659cc inline three-cylinder engine (per Japanese kei car regulations) driving the front wheels through either a 5-speed manual, 4-speed automatic, or the innovative CVT (continuously variable transmission) offered in later models. With its low center of gravity, short wheelbase, and peppy turbocharged engine producing the maximum 64 horsepower allowed under kei regulations, the Copen delivered an engaging driving experience disproportionate to its diminutive dimensions. Designed by Daihatsu with engineering support from Toyota, the Copen was exported to the United Kingdom and other international markets in right-hand drive, where its tiny footprint suited narrow European streets perfectly. Only sold in Japan in left-hand drive for the domestic market. The Copen ceased production in 2012 due to tightening kei car safety standards but remains a beloved and collectible micro roadster.
