The new take on the shooting brake body style, Numéro 9 has elegant, thoroughbred looks enhanced with further radical design elements. Solid, sculpted proportions and subtle lines convey a distinctive and sophisticated character. The sophistication is allied with a high-quality finish for a truly original driving sensation and features that are practical and versatile in everyday use.
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. Designed in Paris, Numéro 9 opens a new chapter in the styling of the DS line.
Numéro 9 evolves the design cues of the current DS line, introducing the new front-end identity of future models, along with an original light signature. The grille is sculpted in 3 dimensions and flows into the full-LED headlights, which end in daytime-running lights. Condensing the distinctive forms of the DS line, the concept also features a floating roof, underlined by chrome trim with discreet DS markings, and glazed side surfaces flowing into the rear window.
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 drivetrain combines a conventional petrol or diesel engine (depending on the market) with an electric motor on the rear axle that develops 70 hp and torque of 200 Nm. 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 225 hp (165 kW) and 275 Nm of torque.
It has a range of 50 km (around 31 miles) 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. On the motorway, the combustion engine takes over to deliver real performance. 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 295 hp). Numéro 9 takes just 5.4 seconds to go from 0 to 62 mph and 25.3 seconds to travel 1,000 m 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.
