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.
