4,134cc V8 debuted in Cayenne S Diesel at 2012 Paris show, gained 2kW in facelifted model at 2014 Paris show

The Volkswagen Group's 4,134cc diesel V8, as featured in the Porsche Cayenne, is not being modified for Euro 6 emissions norms, just-auto.com has learned. Despite this, it is still part of the newly-updated SUV's model range.

In the Cayenne, the V8 powers the S Diesel derivative. Its power output is 283kW (385hp). While this is obviously far lower than the 419kW (570hp) of the latest petrol-engined Turbo S, its 850Nm is still higher than that of this, the most powerful Cayenne. The facelifted Turbo S has just been revealed at the 2015 Detroit auto show. Previously, it produced 750Nm but the engine has gained 50Nm as well as 20hp.

A spokesman for Porsche told just-auto.com that there are no plans to update the diesel V8 as "it isn't a simple process to make the engine Euro 6-compliant". As the eight-cylinder diesel sells well in certain countries such as Germany and the UK, the issue of a potential replacement engine "is being studied".
