Citroen Unveils New 240HP 3.0 HDi V6 Diesel for C5 and C6 Range

French carmaker Citroen just announced a new range-topping diesel engine for its C5 Sedan and Estate and C6 models. The replacement for the firm's 2.8-liter HDi V6 diesel has grown in size to 3.0-liters and now features a new, third-generation direct injection / common rail system. The 3.0-liter twin-turbocharged V6 diesel produces an output of 240HP and a maximum torque of 450Nm or 331.9-lbs/ft at 1,600 regime rpm, up from the 2.7 HDi's 208HP and 440Nm.

As with the 2.8 HDi, the new 3.0 HDi V6 is coupled to a six-speed automatic gearbox. With the new powertrain, the C5 and C6 accelerate from standstill to 100km/h (62mph) in 7.9 and 8.5 seconds respectively

Despite the 32-horspower spike, Citroen said that fuel consumption and C02 emissions on both cars have been reduced by 12 to 15 percent over the outgoing models with the 2.7 HDi V6. According to the French carmaker, both the C5 and C6 3.0 HDi achieve an average fuel consumption of 7.4 liters of diesel per 100 km (31.8mpg US) with CO2 emissions of 195 g/km.

Paris Show: Citroën Updates C5 with LEDs and New Engines

Citroën chose the Paris Motor Show today to roll out its updated C5 sedan and estate (Tourer) models. The French firm's VW Passat rival has been refreshed for the 2011 model year with some modest styling changes and technology upgrades.

Since the C5 has only been out since early 2008, the cosmetic updates were kept to a minimum and concern the front headlamps that gain a strip of LEDs and the revised tail lamps that receive a new "Dark Crystal" treatment with clear glass in the central section.

There are more important changes under the hood with the introduction of a new e-HDi engine and a new generation 2.2-liter turbo diesel unit.

The e-HDi marries a 110HP four-cylinder diesel to Citroën's 'micro hybrid technology' featuring a stop-start system and a smart alternator able to recover energy during braking. This model also gets an EGS6 electronic gearbox system with steering-wheel paddles and low rolling resistance tires. According to the French automaker, the C5 e-HDi returns a combined fuel economy figure of 4.6 lt/100km (51.2 mpg US) and emits 120 g/km of CO2.

The second new engine in the range is a 2.2-liter turbo diesel producing 200-horsepower and a maximum torque of 450 Nm. Mated to a 6-speed automatic gearbox, this engine offers the C5 a top speed of 230 km/h (225 km/h for the Tourer), a 0-100 km/h sprint time of 8.3 seconds (Tourer: 8.6) and a combined cycle fuel consumption of 5.9 lt/100 km or 39.9 mpg US (Tourer: 6.1lt/100km). The saloon emits 155 g/km of CO2 and the Tourer 159 g/km.

Citroën said the new C5 model range will go on sale across Europe in the fourth quarter of the year.
