Citroen C5

Citroen has announced that it will start using the BMW-PSA Prince engine, which comes in normally aspirated 120 horsepower form and turbocharged 150 horsepower and 175 horsepower form, and the engine’s first usage in a Citroen car could be in the second generation Citroen C5. It’s sister marque Peugeot already uses it in the Peugeot 207 and the Peugeot 308, which are B-segment and C-segment hatchbacks respectively.

The normally aspirated Prince engine is called the EP6 internally by Peugeot and features variable valve timing and Valvetronic variable valve lift, while the 150 horsepower turbocharged version is called the EP6DT, and the 175 horses version EP6DTS. The turbocharged versions do not have Valvetronic, but feature direct injection and a twin scroll turbocharger.

Large cars with small displacement engines that have forced induction to boost power output are no stranger in these days, as even the large Volkswagen Passat can be equipped with the 1.4 litre TSI engine.

The Citroen C5 currently comes with two petrol engines and four HDi turbodiesels – a 127 horsepower 1.8 litre petrol, a 143 horsepower 2.0 litre petrol and multiple turbodiesels from a 110 horsepower 1.6 litre inline-4 up to 208 horsepower V6. The top of the pops 175 horsepower turbocharged 1.6 litre Prince could slot in as the top of the range petrol engine, equipped with a ZF 6-speed quick shifting automatic.
