Citroen 2010 C5

The first is a new 2.0HDi 16V 119kW diesel that will replace both the existing 2.0- and 2.2-litre diesels. Based on the 3.0-litre V6 twin turbo-diesel that has just been released in the Jaguar XF and is heading for the Land Rover Discovery before the end of 2009, the new engine lifts power and torque but slashes fuel consumption and emissions compared to its 150kW/440Nm 2.7-litre V6 HDi twin-turbo predecessor.

Dubbed the 3.0 V6 HDi 240 FAP to reflect its European horsepower rating, the 2993cc engine delivers 18 per cent more power (177kW at 3800rpm) and about 12 per cent more torque (450Nm from 1600 to 3600rpm).

Bigger is better: The Citroen C5 will get a bigger, 3.0-litre diesel next year in Australia, with more power and improved fuel economy.

This translates into a 0-100km/h sprint-time of 7.9 seconds in the C5 (formerly 9.6s) and 8.5 seconds in the C6 (previously rated at 8.9 seconds).

Nevertheless, there are significant gains in fuel consumption, with the 7.4 litres per 100km average representing a cut of 1.0L/100km and 1.5L/100km in the C5 and C6 respectively, while the 195 grams per kilometre of carbon dioxide emissions is 12 to 15 per cent better than before.

Spurring on the changes are a 272cc capacity increase, third-generation direct common-rail injection system using injection pressures of up to 2000 bars, compared with 1650, revised combustion chambers, twin variable displacement turbochargers, a revamped exhaust gas recirculation set-up that improves the thermal capability of the fuel/water exchange by 40 per cent, and an energy recovery system during deceleration and braking via a special new alternator.
