Last week, French automaker PSA-Peugeot-Citroen announced the development of the world's first hybrid diesel powertrain. Called HYbrid4, the propulsion system is earmarked for initial implementation on the Peugeot 3008 crossover. But after that, its sister-company Citroen will use the system in an all-new vehicle: the DS5.

Following on the heels of the Citroen DS3 premium hatchback displayed at this year's Geneva Motor Show, the DS5 will be the second vehicle in the company's revived premium line. Styling, as this initial rendering suggests, should follow along the same line, but in a sleeker, more elongated form. But the real party trick will be under the hood, with the option of serial or parallel hybrid propulsion through the front, rear or all four wheels, all the while reducing complicated moving parts in the process. Sources suggest the use of the HYbrid4 system would add less than $3,000 to the car's list price, while returning significant improvement in fuel economy and emitting 35% less CO2 than even its particulate-filtering conventional counterparts. The Citroen DS5 could be on the road as early as 2011.
