The PSA EW/DW engine is a family of straight-4 petrol and diesel engines manufactured by the PSA Group for use in their Peugeot and Citroën automobiles. The EW/DW family was introduced in 1998 as a replacement for the XU engine. All DW engines are produced as part of a joint venture with Ford Motor Company.
All EWs are DOHC multivalve with displacement from 1.7 to 2.2 L (1,749 to 2,231 cc). They are mainly used for large family cars and executive cars, as well as large MPVs, although the 2.0 L is also used for some hot hatch models.
The DW started with an SOHC 2-valve design between 2.0 to 2.0 L (1,968 to 1,997 cc), later receiving DOHC and four valves per cylinder upon the introduction of the 2.2 L in 2000 with the Citroën C5 and Peugeot 607. Turbocharged versions started using common rail and received the commercial designation HDi. The DW10 served as the basis for the Ford/PSA engine partnership using second generation common rail and a variable-geometry turbocharger for the first time on the 2.0 L design.
The DW8 is for all intents and purposes an evolution of the XUD9 and was the only diesel engine in the family not to feature a turbocharger or common-rail direct injection. It was mainly used in vans such as the Citroën Berlingo and Peugeot Partner but can also be found in more affordable versions of the Peugeot 206 and 306. The DW8 was phased out in 2007 as it does not pass Euro 4 emissions regulations (it is a Euro 3 engine). The DW8 is matched to the BE manual 5-speed and has 250 N⋅m (184 lb⋅ft) of torque.

The 2.0 L DW10 was the first PSA Diesel engine to feature common rail direct injection, and was given the commercial designation HDi. It has a bore and a stroke of 85 mm × 88 mm (3.35 in × 3.46 in) for a total displacement of 2.0 L (1,997 cc), replacing the XUD9 in 1999. It was initially available in 90 PS (66 kW; 89 hp) form, with two valves per cylinder and a non-intercooled turbo. An intercooler was added later in the year, boosting power to 109 PS (80 kW; 108 hp).
Initially available in the midsized models, such as the Citroën Xsara and Xantia and Peugeot 306, 406 and Peugeot 206 it was soon spread across the PSA range, such as the LCVs, while a 16-valve version(RHW), with 109 PS (80 kW; 108 hp), was used in the large MPVs built in association with Fiat. Suzuki was a customer for these powerplants, using them in the European Vitara, Grand Vitara, and Grand Vitara XL-7. Eurovan-based commercial vans, the Citroën Jumpy, Peugeot Expert and Fiat Scudo were available with a 94 PS (69 kW; 93 hp) DW10 BTED engine, which is essentially an intercooled version of the original 90 PS (66 kW; 89 hp) design.
The DW10 was used as the basis for the new family of Duratorq Diesel engines co-developed with Ford, and it is used in the Focus, Kuga, Mondeo, C-Max and Volvo C30/S40/V50, besides various Citroën and Peugeot passenger models. The DOHC 16-valve powerplants were mated to a second generation common rail injection system and a variable-geometry turbocharger, pushing power to 136 PS (100 kW; 134 hp) (RHR). It is fitted with a six-speed manual transmission or six-speed Aisin-automatic transmission (in Citroën C5 from summer 2004 onwards).

The 2.2 L (2,179 cc) DW12 has a bore and a stroke of 85 mm × 96 mm (3.35 in × 3.78 in). Unlike the initial DW10 designs, it was fitted with 16 valves from the beginning, and made its debut in the 2000 with the Citroën C5, Peugeot 406, Peugeot 406 Coupe and Peugeot 607, being used only in the larger models. In 2006 it was added to the PSA/Ford family, with power reaching 170 PS (125 kW; 168 hp). Land Rover used this engine in the Freelander 2 and Range Rover Evoque. Available as both 160ps or 190ps, Peugeot 4007 and Citroën C-Crosser used the same motor. The unit was used in a longitudinal mounting in the Jaguar XF from 2012 until 2015 in 163 PS or 200 PS, though some early 2012 cars were available as 190 PS. A different 2.2 L engine, Ford's ZSD-422 with a displacement of 2.2 L (2,198 cc) was used in the Citroën and Peugeot LCV range of vans.
The same engine, after being reworked on independently by AVL (engineering company) has been used extensively by Tata Motors in their Safari (1st Gen), Aria, Hexa, Xenon and Winger and by Mahindra and Mahindra in their XUV500 and Scorpio models. The Tata Hexa and Tata Safari (2016+) have an output of 156 PS while the Mahindra XUV500 churned 155PS. While Tata Motors discontinued the engine in 2020 with the onset of the Bharat Stage 6 emission standards, only using a commercial grade 98 PS tuned 2.2L in the Tata Winger, Mahindra recently discontinued the XUV500 which only leaves the Mahindra Scorpio using the engine, which is also at the end of its life cycle.

The DW12 RU is an updated version that meets Euro 6d emission standards, and is intended for light commercial vehicle applications where it replaces the DW10 FU. The Citroën Jumper and Peugeot Boxer (2019–) are powered by this engine. It comes in power ratings of 120 PS/300 Nm, 140 PS/340 Nm and 165 PS/370 Nm.
The EW7 has a bore and a stroke of 82.7 mm × 81.4 mm (3.26 in × 3.20 in), for a displacement of 1.7 L (1,749 cc). It is used as an entry level engine for the Citroën C5, the Peugeot 406 and the Peugeot 407.
|EW7 J4||117 PS (86 kW; 115 hp)||16-valve catalyst|
|EW7 A||125 PS (92 kW; 123 hp)|
The EW10 has a bore and a stroke of 85 mm × 88 mm (3.35 in × 3.46 in), for a displacement of 2.0 L (1,997 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 in 2003 due to low sales.
The EW10 J4S variant is a high performance version used in the 206 GTI 180, 206 RC, 307 Féline, 307 cc and C4 VTS. Power was raised to 177 PS (130 kW; 175 hp), although the two French brands round it up to 180 PS (132 kW; 178 hp) 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 140 PS (103 kW; 138 hp) at 6000 rpm and torque 200 N⋅m (148 lb⋅ft) at 4000 rpm. Citroën usually states 143 PS (105 kW; 141 hp) and Peugeot 140 PS for the same 140 PS (103 kW; 138 hp) engine.
|EW10 D (RLZ)||140 PS (103 kW; 138 hp)||Gasoline direct injection catalyst|
|EW10 J4 (RFN)||136 PS (100 kW; 134 hp)||16-valve catalyst|
|EW10 J4 (RFR)||135 PS (99 kW; 133 hp)|
|EW10 J4S (RFK)||177 PS (130 kW; 175 hp)||16-valve VVT catalyst|
|EW10 A (RFJ)||143 PS (105 kW; 141 hp)|
The EW12 was introduced to replace the low-pressure turbo variant of the XU10. It has a bore and stroke of 86 mm × 96 mm (3.39 in × 3.78 in), for a displacement of 2.2 L (2,231 cc). Citroën only uses it on the C8 MPV, while Peugeot, which has more a sporty image, uses it in the 406 SRi and 406 Coupe, 407, the 607 executive model and 807 MPV.
The EW12J4 is Euro 4 only, and no longer for sale in Europe as of January 1, 2011.
|EW12 J4 (3FZ)||158–163 PS (116–120 kW; 156–161 hp)||16-valve catalyst|
