Could the Copen be ready for a comeback? This concept car suggests it very well could. Back in 1999 Daihatsu introduced a nimble little roadster called the Copen. Powered by a tiny 660cc turbocharged two-cylinder engine (and later by a larger 1.3), the Copen conformed to Japan's popular kei car formula.The roadster, however, never made much of a mark outside of its home market, and about a year and a half ago Daihatsu pulled it from the European market. But it could be preparing to replace it with a new model. Source: Carbuzz
