The Petrol PSA V6 ESL engine also known under the code "engine ES" PSA and "motor L7X" is an automobile internal combustion gasoline four-stroke, six-cylinder V with dry cast iron liners in the aluminium block, cooled by water, with 4 camshafts head, driven by a belt distribution notched with two yokes constructed entirely in aluminium, and DOHC 24-valve type.
ESL is the acronym for ES (PSA) and L (the Renault). This replaced the old “V6 PRV engine “used in Peugeot, Renault and Volvo. It is the result of a collaboration between the two French car manufacturers PSA and Renault, and its costs were shared. For Renault, it is part of a motor investment campaign of about 2 billion Euros. The "V6 ESL engine" is machined and assembled at Douvrin, in the plant of the Société Française de Mécanique created in 1969 by Renault and Peugeot, each of which owned 50% of the company.
It was later updated in 2000 for the release of the Peugeot 607 and the Citroën C5, and continued on the Peugeot 406 and 406 Coupé with help from Porsche introducing variable valve timing its power is increased to 155 kW (211 hp EEC) as the ES9 J4S version.
Renault with its engine SOLUTION pushes the power even more for its Clio V6, its power is raised to 230hp (169 kW). For its Clio V6 phase 2, the injection ramp is split and the injectors are 50% bigger. The preparation, once again at Porsche Engineering, allows the engine to develop 255 hp (188 kW), making it one of the best V6 of the time.
The Renault-Nissan Alliance led Renault to use the " V6 VQ “Nissan of 3.5 litres so this engine is no longer available in any form since it was removed from the Citroën C5 II in January 2, 2010. It had been used up to in 2009 on the Peugeot 607, 407 Coupé and the Citroën C6.
