CITROEN IS DEVELOPING an ultra-efficient version of its big C6 sedan, which thanks to the company’s diesel hybrid powertrain, will reportedly emit no more than 100g of CO2 per kilometre - a class-leading effort, if the French manufacturer is successful.
According to British magazine Autocar, sources inside Citroen say the diesel hybrid powertrain of the C6 will utilise the same layout as the Peugeot 3008 hybrid concept, unveiled at the Geneva Motor Show in March.
The hybrid powertrain of the Peugeot 3008 is a 121kW (163hp) 2.0 litre HDi four-cylinder turbo-diesel, mated to a 27kW (37hp) electric motor.
The transversely-mounted turbo-diesel, fitted with stop-start technology, drives the front wheels, while the electric motor lends its power to the rear wheels.
PSA promises a fuel economy for the 3008 hybrid of 4.1 l/100km, with CO2 emissions down to 109g/km - notably higher than the sub-100g/km figure Autocar has reported.
Similar to Volkswagen’s BlueMotion concepts, the C6 will likely benefit from additional aid in the form of an encased underbody and semi-enclosed rear wheels, along with low-rolling-resistance tyres.

This is great technology. Fuel saving and torque figures should be remarkable. I hope they apply this drive-train or similar to the new incarnation of the ‘Goddess’.
