It was co-developed by the [[PSA Group]] ([[Peugeot]] and [[Citroën]]) and [[Renault]] to replace the outdated [[V6 PRV engine]]. It was introduced in 1997 with the [[Peugeot 406]] [[Coupé]]. It is designed and manufactured by the company "Française de Mécanique" for PSA and Renault. In PSA, the engine is known as the '''ES engine''', in Renaults, the engine is known as the '''L engine'''.
Unlike the PRV V6, which was a 90° engine because it was developed from a [[V8 engine|V8]] project, the ES/L has a traditional 60° V-angle. It is constructed entirely in [[aluminum]], and available only in [[DOHC]] [[multi-valve#Four valves|24-valve]] format. Its sole iteration, the ES9 (PSA) or L7X (Renault), has a displacement of {{cvt|2946|cc|L|1}}, slightly less than the 3.0 L variant of the PRV. [[Bore (engine)|Bore]] and [[stroke (engine)|stroke]] is {{cvt|87x82.6|mm}}. A 3.3 L version was initially planned as well, but did not see production due to decreasing demand in V6 [[petrol engine]]s in Europe and Renault's switch to [[Nissan]]-sourced V6 after its alliance with the Japanese carmaker.
Initially, the ESL produced {{cvt|140|kW|PS bhp|0}} in accordance with German and French insurance category limits in force at the time for engines under 3 litres. (The BMW 2.8 and Audi 2.8 produced the same figure circa {{cvt|194|PS|kW bhp|0}}) In 2000, [[Porsche]] retuned the Peugeot/Citroën version of the engine introducing [[variable valve timing]] on the intake [[camshaft]]s varying between 0 and 40 degrees, improving [[Fuel consumption in automobiles|fuel consumption]], low engine speed flexibility for the introduction of the [[Peugeot 607]] and [[Citroën C5]]. This iteration, called ES9 J4S, can now achieve {{cvt|152|kW|PS bhp|0}}. In 2005, Peugeot/Citroën slightly upgraded the power to {{cvt|155|kW|PS bhp|0}}. This version was not used by Renault who was by then focusing on Nissan-developed V6.
In 2000, [[Tom Walkinshaw Racing]] created a competition version for use in the [[Renault Clio V6]]. It could achieve a maximum of {{cvt|206|kW|PS bhp|0}} in racing trim, with a version detuned to {{cvt|169|kW|PS bhp|0}} for the road car. The road version's power was improved to {{cvt|187|kW|PS bhp|0}} by [[Renault Sport]] in 2004.
== ES9/L7X == The ES/L V6 has been used in a variety of cars from Citroën, Peugeot and Renault in the executive and luxury segments, namely the [[Citroën XM]], [[Citroën Xantia]], [[Citroën C5]], [[Citroën C8]] and [[Citroën C6]]; the Peugeot [[Peugeot 406|406]], [[Peugeot 407|407]], [[Peugeot 605|605]], [[Peugeot 607|607]] and [[Peugeot 807|807]]; and the [[Renault Laguna]] (Mk.I and II), [[Renault Espace|Espace]] (Mk.III), [[Renault Avantime]], [[Renault Safrane]] and Clio V6. It was also modified by [[Venturi Automobiles|Venturi]] into a {{cvt|310|PS|kW hp|0}} [[twin-turbo]] in the last of their [[Venturi Atlantique|Atlantique 300 Bi-turbo]] cars.<ref>{{cite web|url=https://www.automobile-sportive.com/guide/venturi/atlantique300.php|website=automobile-sportive.com|title=Venturi Atlantique-300 (1996 - 2000)|editor-first=Sébastien | editor-last = Dupuis|language=fr-fr|access-date=June 18, 2018}}</ref> Unlike the PRV, it didn't have much of a career in motorsport, next to the Renault Sport Clio V6 Eurocup the engine was also used by [[Courage_Compétition|Courage]] in the [[Courage C52|C52]] and [[Courage C60|C60]], as a 3.2 L [[bi-turbo]] engine, with a max output of {{cvt|650|PS|kW|0}}. The engines are built by [[Sodemo]].
== PSA == With Renault shifting to the [[Nissan VQ engine]] 3.5 L V6, PSA became the sole user of the ES until 2010 when the requirements of [[Euro 5]] emission regulations began; the [[Euro 4]]-only ES engine was no longer available in Europe and replaced by The [[turbocharged]] [[Straight-4]] [[Prince engine]].
