The EW/DW family was introduced in 1998 as a replacement for the [[PSA XU engine|XU engine]].<ref>{{Cite web|url=http://www.autoweb-france.com/indexsanspub.php?rub=22&cat=3|title=Les dossiers Autoweb France|website=www.autoweb-france.com}}</ref> Some DW engines are produced as part of a [[joint-venture]] with [[Ford Motor Company]].
The EW/DW uses many parts from the XU, most notably the [[crankshaft]], but is built with lighter materials. The EW name is used for the petrol engines ("e" for ''[[:fr:Essence (hydrocarbure)|essence]]'') and DW for Diesel engines.
All EWs are [[DOHC]] [[multivalve]] with displacement from {{cvt|1749|to|2231|cc|L|1|disp=flip}}. They are mainly used for [[large family car]]s and [[executive car]]s, as well as [[large MPV]]s, although the 2.0 L is also used for some [[hot hatch]] models.
The DW started with an [[SOHC]] 2-valve design between {{cvt|1968|and|1997|cc|L|1|disp=flip}}, later receiving DOHC and [[Multi-valve#Four valves|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 DLD engine|Ford/PSA engine partnership]] using second generation common rail and a [[variable-geometry turbocharger]] for the first time on the 2.0 L design.
==DW8== The '''DW8''' is for all intents and purposes an evolution of the '''[[PSA XUD#XUD9|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 [[van]]s 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<ref name="Peugeot Citroën Moteurs: Petrol car engines"/>). The DW8 is matched to the ''BE'' manual 5-speed and has {{cvt|127|Nm|lbft|0}} of torque.<ref>{{Cite web|url=http://www.peugeot-citroen-moteurs.fr/en-gb/our-products/Gearboxes/manual#40|title=Manual gearboxes — Peugeot Citroën Moteurs|date=October 3, 2011|archive-url=https://web.archive.org/web/20111003134539/http://www.peugeot-citroen-moteurs.fr/en-gb/our-products/Gearboxes/manual#40|archive-date=2011-10-03}}</ref> This is known as the 1WZ engine in Toyota vehicles.

==DW10== The 2.0 L '''DW10''' was the first PSA Diesel engine to feature [[common rail]] [[Fuel injection#Direct injection systems|direct injection]], and was given the commercial designation ''HDi''. It has a bore and a stroke of {{cvt|85x88|mm|2}} for a total displacement of {{cvt|1997|cc|L|1|disp=flip}}, replacing the [[PSA XUD#XUD9|XUD9]] in 1999. It was initially available in {{cvt|90|PS|kW hp|0}} form, with two valves per cylinder and a non-intercooled turbo. An [[intercooler]] was added later in the year, boosting power to {{cvt|109|PS|kW hp|0}}.
Initially available in the midsized models, such as the [[Citroën Xsara]] and [[Citroën Xantia|Xantia]] and [[Peugeot 306]], [[Peugeot 406|406]] and [[Peugeot 206]] it was soon spread across the PSA range, such as the LCVs, while a 16-valve version(RHW), with {{cvt|109|PS|kW hp|0}}, was used in the large MPVs built in association with [[Fiat]]. [[Suzuki]] was a customer for these powerplants, using them in the European [[Suzuki Vitara|Vitara]], [[Suzuki Grand Vitara|Grand Vitara]], and [[Suzuki XL-7|XL-7]]. Eurovan-based commercial vans, the [[Citroën Jumpy]], [[Peugeot Expert]] and [[Fiat Scudo]] were available with a {{cvt|94|PS|kW hp|0}} DW10 BTED engine, which is essentially an intercooled version of the original {{cvt|90|PS|kW hp|0}} design.
The DW10 was used as the basis for the new family of [[Ford Duratorq engine|Duratorq Diesel engines]] co-developed with [[Ford Motor Company|Ford]] and [[Volvo Cars|Volvo]] it is used in the [[Ford Focus (second generation, Europe)|Focus]], [[Ford Kuga|Kuga]], [[Ford Mondeo (third generation)|Mondeo Mk4]], [[Ford Mondeo (fourth generation)|Mondeo Mk5]], [[Ford C-Max|C-Max]] and [[Volvo C30|C30]]/[[Volvo S40|S40]]/[[Volvo V50|V50]]/[[Volvo C70|C70]], 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 {{cvt|136|PS|kW hp|0}} (RHR). It is fitted with a six-speed [[manual transmission]] or six-speed Aisin-[[automatic transmission]] (in [[Citroën C5]] from summer 2004 onwards).
The '''DW10BTED4E5''' and '''DW10C''' are [[Euro 5]]-compliant, and therefore still available for sale in Europe.<ref name="Peugeot Citroën Moteurs: Car diesel engines"/>
2014 [[Euro 6]] variant DW10FC and DW10FD introduced [[selective catalytic reduction]] emissions control technology.
This engine is known as the 4WZ when installed in Toyota vehicles such as Toyotas [[Rebadging|version]] of the [[Citroën Jumpy#Third generation (K0; 2016)|Citroën Jumpy]].

==DW12== The {{cvt|2179|cc|L|1|disp=flip}} '''DW12''' has a bore and a stroke of {{cvt|85x96|mm|2}}. 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 {{cvt|170|PS|kW hp|0}}. [[Peugeot]] added the engine as an option for the [[Peugeot 407]] and the now facelifted [[Peugeot 607|607]], between the 2.0 DW10 and 2.7 DT17. [[Land Rover]] used this engine in the [[Land Rover Freelander#2|Freelander 2]], [[Land Rover Discovery Sport|Discovery Sport]] and [[Range Rover Evoque#1|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 [[Ford Duratorq engine|ZSD-422]] with a displacement of {{cvt|2198|cc|L|1|disp=flip}} was used in the Citroën and Peugeot LCV range of vans.
The '''DW12C''' is a [[Euro 5]]-compliant, high-output version.<ref name="Peugeot Citroën Moteurs: Car diesel engines"/>

==={{anchor|mHawk|Dicor|Mahindra}} In India=== The DW12 engine has been manufactured in India by [[Tata Motors]] and [[Mahindra and Mahindra]], with the same {{cvt|2179|cc|L|1|disp=flip}} displacement.
Tata used DW12 in their vehicles like [[Tata Safari]], [[Tata Hexa]], Aria, and Xenon. They launched the engine in the 2007 Safari as the '''2.2 Dicor'''. They continued to use it in various models until 2020 when [[Bharat Stage 6]] emission standards forced Tata to discountinue it.
Mahindra re-engineered the engine together with AVL of Austria, calling the new generation the '''mHawk'''. It was introduced in 2009 with the [[Mahindra Scorpio]] CRDe. It is [[Intercooler|intercooled]] and features a [[variable-geometry turbocharger]] (VTG), delivering maximum power of {{cvt|140|PS|bhp kW|0}} and {{cvt|320|Nm|lbft|0}} of torque. A Bosch common-rail direct-injection system with solenoid injectors is used. The mHawk is equipped with chain-driven overhead camshafts and hydraulic lash adjusters; its compression ratio ranges from 16.5:1 to 18.5:1 depending on the model. It was then installed on the Scorpio pickup verson, and in 2012 it was carried over to the [[Mahindra Xylo]]. It has been available on the [[Mahindra XUV500]] with a fifth generation VGT since 2011, updated to sixth generation e-VGT in 2018. In 2020 Mahindra revised the engine to meet [[Bharat Stage 6|BS6]] and then BS6.2 in 2023. Called the second geenration mHawk, this was launched in the [[Mahindra Thar]], [[XUV700]], [[Mahindra Scorpio|Scorpio]], and later on other models as well.
==EW7== The '''EW7''' has a [[bore (engine)|bore]] and a [[stroke (engine)|stroke]] of {{cvt|82.7x81.4|mm|2}}, for a displacement of {{cvt|1749|cc|L|1|disp=flip}}. It was used as an entry-level engine for the [[Citroën C5]] and [[Citroën Xsara Picasso]], the [[Peugeot 406]], and the [[Peugeot 407]].
As of January 1, 2011 and the requirements of [[Euro 5]] emission regulations, the EW7 ([[Euro 4]] only<ref name="Peugeot Citroën Moteurs: Petrol car engines"/>) is no longer available in Europe. For most use, it was replaced by the 1.6 litre turbocharged version of the [[Prince engine#turbo|Prince engine]].
{| class="wikitable" !Model !Code !Output !Notes |- |EW7 J4 || 6FZ ||{{cvt|117|PS|kW hp|0}}||rowspan=2|16-valve [[Catalytic converter|catalyst]] |- |EW7 A || 6FY ||{{cvt|125|PS|kW hp|0}} |}
==EW10== The '''EW10''' has a bore and a stroke of {{cvt|85x88|mm|2}}, for a displacement of {{cvt|1997|cc|L|1|disp=flip}}. It is used widely throughout the PSA Group, including the [[Citroën C4]], [[Citroën C5|C5]], [[Citroën Xsara]], [[Citroën Xsara Picasso]] and [[Peugeot 206]], [[Peugeot 307|307]] and [[Peugeot 407|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 {{cvt|177|PS|kW hp|0}}, although the two French brands round it up to {{cvt|180|PS|kW hp|0}} 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 in automobiles|Fuel consumption]] is also decreased. Power is {{cvt|140|PS|kW hp|0}} at 6000 rpm and torque {{cvt|200|Nm|lbft|0}} at 4000 rpm. Citroën usually states {{cvt|143|PS|kW hp|0}} and Peugeot 140 PS for the same {{cvt|140|PS|kW hp|0}} engine.
As of January 1, 2010 and the requirements of [[Euro 5]] emission regulations, the EW10 ([[Euro 4]] only<ref name="Peugeot Citroën Moteurs: Petrol car engines"/>) is no longer available in Europe. For most use, it is replaced by the 1.6 litre turbocharged version partially based on the [[Prince engine#turbo|Prince engine]].

==EW12== The '''EW12''' was introduced to replace the low-pressure turbo variant of the XU10. It has a bore and stroke of {{cvt|86x96|mm|in|2}}, for a displacement of {{cvt|2231|cc|L|1|disp=flip}}. Citroën only uses it on the [[Citroën C8|C8]] MPV, while Peugeot, which has more a sporty image, uses it in the [[Peugeot 406|406]] SRi and 406 Coupe, [[Peugeot 407|407]], the [[Peugeot 607|607]] executive model and [[Peugeot 807|807]] MPV.
As of January 1, 2011 and the requirements of Euro 5 emission regulations, the EW12 (Euro 4 only<ref name="Peugeot Citroën Moteurs: Petrol car engines"/>) is no longer available in Europe. It was replaced by the 1.6 litre turbocharged [[Prince engine#turbo|Prince engine]].
