In addition, to comply with the European Whole Vehicle Type Approval, Daihatsu equipped the Copen with a larger 1.3 litre petrol engine that now pumps out an additional 19 hp and a 14.5 lb.-ft. increase of peak torque, for a total of 86 hp at 6,000 rpm and peak torque of 88.5 lb ft at 4,400 rpm. Daihatsu said the Copen offers an improved fuel efficiency and low fuel consumption rate, thanks to the advance engine systems like Dynamic Variable Valve Timing (DVVT) which enhances low-speed pulling power, the compact twin overhead camshaft unit equipped with alloy head and block. Moreover, the Daihatsu Copen also comes with the first ever self regenerating catalytic converter made palladium, the most heat sensitive material used in catalytic converters. As a result, the catalytic converter has the ability to regenerate and prolong its function in reducing CO2 exhaust emission coming out from the Daihatsu Copen.
With the new engine, the Daihatsu Copen can now sprint from 0 to 62 mph time in just 9.5 seconds, about 2 seconds faster than the previous 660 cc engine. The Copen roadster can reach an electronically limited full throttle speed of 112 mph.
According to Paul Tunnicliffe, Daihatsu Managing Director, "We are all car enthusiasts here at Daihatsu and were instrumental in bringing the original model to market in the UK. With this lively new engine and a highly competitive price, we are delighted not only to have a 'halo' model in our range but to be able to offer fellow enthusiasts such a characterful and affordable fun car.
