ThePSA ES/L engine is aV6petrol engine used in automotive applications. It was co-developed by thePSA Group (Peugeot andCitroën) andRenault to replace the outdatedV6 PRV engine. It was introduced in 1997 with thePeugeot 406Coupé. It is designed and manufactured by the company "Française de Mécanique" for PSA and Renault. In PSA, the engine is known as theES engine, in Renaults, the engine is known as theL engine.
Unlike the PRV V6, which was a 90° engine because it was developed from aV8 project, the ES/L has a traditional 60° V-angle. It is constructed entirely inaluminum, and available only inDOHC24-valve format. Its sole iteration, the ES9 (PSA) or L7X (Renault), has a displacement of 2,946 cc (2.9 L), slightly less than the 3.0 L variant of the PRV.Bore andstroke is 87 mm × 82.6 mm (3.43 in × 3.25 in). A 3.3 L version was initially planned as well, but did not see production due to decreasing demand in V6petrol engines in Europe and Renault's switch toNissan-sourced V6 after its alliance with the Japanese carmaker.
Initially, the ESL produced 140 kW (190 PS; 188 bhp) 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 194 PS (143 kW; 191 bhp)) In 2000,Porsche retuned the Peugeot/Citroën version of the engine introducingvariable valve timing on the intakecamshafts varying between 0 and 40 degrees, improvingfuel consumption, low engine speed flexibility for the introduction of thePeugeot 607 andCitroën C5. This iteration, called ES9 J4S, can now achieve 152 kW (207 PS; 204 bhp). In 2005, Peugeot/Citroën slightly upgraded the power to 155 kW (211 PS; 208 bhp). 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 theRenault Clio V6. It could achieve a maximum of 206 kW (280 PS; 276 bhp) in racing trim, with a version detuned to 169 kW (230 PS; 227 bhp) for the road car. The road version's power was improved to 187 kW (254 PS; 251 bhp) byRenault Sport in 2004.
The ES/L V6 has been used in a variety of cars from Citroën, Peugeot and Renault in the executive and luxury segments, namely theCitroën XM,Citroën Xantia,Citroën C5,Citroën C8 andCitroën C6; the Peugeot406,407,605 and607; and theRenault Laguna (Mk.I and II),Espace (Mk.III),Renault Avantime,Renault Safrane and Clio V6. It was also modified byVenturi into a 310 PS (228 kW; 306 hp)twin-turbo in the last of theirAtlantique 300 Bi-turbo cars.[1] 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 byCourage in theC52 andC60, as a 3.2 Lbi-turbo engine, with a max output of 650 bhp (485 kW; 659 PS). The engines are built bySodemo.
With Renault shifting to theNissan VQ engine 3.5 L V6, PSA became the sole user of the ES until 2010 when the requirements ofEuro 5 emission regulations began; theEuro 4-only ES engine was no longer available in Europe and replaced by TheturbochargedStraight-4Prince engine.
