Copen was originally designed with a 660 cc turbocharged engine in order to meet Japanese kei car regulations. However, since this engine did not meet environmental emissions standards in several other countries, the Copen was fitted with a more powerful 1.3 L non-turbo engine in these markets in 2007.
The Copen was officially sold in Germany from 2003 to 2005 and with smaller 660cc engine. For 2006, Copen was offered in Germany a bigger 1300cc engine.
On January 13, 2011, Daihatsu announced that it would withdraw the Copen from the European market effective from 31 January 2013 due to the ongoing strength of the Japanese Yen. Then on April 2, 2012, Daihatsu announced that Copen production would cease in August 2012 with the final 500 cars being limited 10th Anniversary editions.

Less than one year after the car's discontinuation, Daihatsu announced the Copen would be returning to production with a new model. At the 2013 Tokyo Motor Show, Daihatsu unveiled two Copen concept cars called the Kopen, with the tagline "Future Included". The name "Kopen" was a combination of kei class car, and "open" for convertible roadster. The spelling was changed from "k" to "c" for "convertible". Production of the new model was announced on June 19, 2014.
The Copen has been restyled to be more angular than its predecessor with a new monocoque chassis structure called a D-Frame. The structure allows owners to select the interior and exterior design of the car according to their preferences. The body panels are made of 13 separate resin components, 11 of which are interchangeable to modify design and colors. The Copen also features a new suspension system, a new 660cc turbo three-cylinder engine with DVVT, better sounding exhaust system and weight reduction. In Japan, models sold were Copen XPlay, Copen Robe and a special S type for the Copen Robe.
The Copen was exported to Indonesia officially and was available between 2014 and 2018.
In 2015, Daihatsu released the Copen Cero, which has a shape close to that of the first generation model.
At the 2019 Tokyo Auto Salon, Daihatsu unveiled the Copen Coupe, a fixed-roof coupé version of the Copen Cero. The CFRP roof features an optional sunroof. Standard features include a Momo leather wrapped steering wheel, limited-slip differential, BBS aluminum wheels, and serialized plates on the center console. Options include a sports muffler and HKS suspension. Daihatsu plans to produce a limited run of 200 units in April 2019 to coincide with the fifth anniversary of the second generation Copen.
