The EW10 has a bore of 85 mm and a stroke of 88 mm, for a displacement of 1997 cc. It is used widely throughout the PSA Group, including the Citroën C4 and C5 and Peugeot 206 307 and 407. A gasoline direct injection variant, called EW10 D and marketed as HPi, was briefly used in the Citroën C5 and Peugeot 406 starting in 2001, but was discontinued at the beginning of 2005 due to low sales. The EW10 J4S variant is a high performance version used in the 206 GTI 180, 206 RC, 307 Féline and C4 VTS. Power was raised to 177 PS (130 kW), although the two French brands round it up to 180 PS in advertising. EW10 A is a further development of the EW10 J4, presenting somewhat higher power and torque due to the introduction of Variable Valve Timing (VVT). Fuel consumption is also decreased. Power is 103 kW at 6000 rpm and torque 200 N·m at 4000 rpm. Citroen usually states 143 PS and Peugeot 140 PS for the same 103 kW engine.
As of January 1, 2010 and the requirements of Euro V emission regulations, the EW10 (Euro IV only) is no longer available in Europe. For most use, they are replaced with Prince engines.
