    Marketed in parallel alongside Citroën’s main range, the distinctive DS line explores new automotive territory. Based on more radical choices, it opens new perspectives in premium vehicle design and illustrates the best of Citroën’s expertise in creativity and technology. Just two years after its launch, the DS line - comprising of Citroën DS3, DS4 and DS5 - has already notched up more than 200,000 sales worldwide.

    The DS line will be launched in China this year and, to mark the event, Citroën has designed a new concept car, Numéro 9, which will be unveiled at the Beijing Motor Show. The concept signals the styling cues of the next three DS line models: a C-segment premium sedan, an SUV and a D-segment executive saloon.

    The concept is designed with plug-in full-hybrid technology; an ultra-efficient system that boasts remarkable levels of performance - 166mpg fuel economy, 50km range in ZEV mode, 295hp, a ‘boost’ function and 39g/km of CO2.

    Subtly combining the proportions of a coupé with those of an estate, Numéro 9 hints at exceptional driving sensations, with its taut lines, long bonnet and ultra-low stance (1.27m tall) on 21-inch wheels. It also promises unique onboard comfort with its generous proportions (4.93m long and 1.94m wide, with a 3m wheelbase) providing plenty of room for rear occupants. The three glass areas in the roof also create a welcoming, friendly cabin ambience.

    Every detail was designed to contribute to Numéro 9’s aerodynamic efficiency (CdA = 0.61) including:
    - a rear spoiler, which reinforces the fastback effect
    - windscreen pillars that contribute to efficient air flow around the car
    - ‘Turbine’ wheels with integrated fins to increase the air flow around the wheel arches, reducing both turbulence and fuel consumption.

    The advanced drivetrain combines a conventional petrol or diesel engine (depending on the market) with an electric motor on the rear axle that develops 70hp and torque of 200Nm. The electric motor is powered by lithium-ion batteries that can be recharged in just 3½ hours from a normal domestic socket. The model on display at the Beijing Motor Show is fitted with a 1.6 THP petrol engine developing 225hp (165kW) and 275Nm of torque.
        
    With its plug-in hybrid technology, Numéro 9 respects the environment. It has a range of 50km (around 31miles) in all-electric ZEV (Zero Emission Vehicle) mode and, on roads demanding successive acceleration and deceleration, the hybrid drivetrain limits consumption by using both sources of energy. Numéro 9 features new-generation micro-hybrid technology designed to switch the combustion engine to stand-by whenever it is not required.

    When the driver requires speed and torque, a ‘boost’ function combines the power of the combustion engine and electric motor to enable high levels of performance (up to 295hp). Numéro 9 takes just 5.4 seconds to go from 0 to 62mph and 25.3 seconds to travel 1,000m from a standing start.

    When grip is lacking, the car switches to four-wheel drive mode with the electric motor driving the rear wheels and the combustion engine powering the front wheels. In particularly difficult driving conditions, such as driving up a sloping, snow-covered road, the driver can manually select 4WD mode. The four-wheel drive system and hydraulic active suspension then deliver increased traction, making full use of the potential of Numéro 9 in complete safety.

    Looking beyond on-road performance and environmental benefits, the full-hybrid plug-in technology offers a third advantage: the cabin can be prepared before the car is used. For example, it can be pre-heated to ensure the comfort of all the occupants as soon as they climb onboard.
