PSA Peugeot Citroën has announced plans to develop ultra-clean hybrid diesel-electric technology that could eventually be offered in family hatchbacks such as the Peugeot 307 and Citroën’s Xsara replacement, the C4.
The proposed hybrid powertrain has a carbon dioxide emissions target of just 89.5g/km over the combined cycle, compared with 120g/km for the current cleanest 307, the 1.4Hdi.
The £3 million Efficient-C project is being funded by the Government’s Ultra-Low Carbon Vehicle Challenge. The first 18 months will be spent developing a hybrid powertrain, mating a 90bhp common-rail diesel engine to a direct-current electric motor and an automated manual transmission in a Citroën Berlingo Multispace.
A stop/start function for the diesel engine and all-electric power at low speeds will conserve fuel in town, while the motor-generator will recharge under braking. Energy will be stored in a bank of nickel-metal hydride or lithium-ion batteries.
PSA has teamed up with automotive consultancy Ricardo UK Ltd and technology experts from QinetiQ.
