French hybrid diesel

Building on 90 years of innovation, the Citroën brand has extended its product offer and developed a new line to stand alongside its main range: the DS line. Today comprising the Citroën DS3 and DS4, the DS line targets customers looking for radical and assertive cars and seeking a resolutely modern approach to premium products.

The Citroën DS5, set for launch in late 2011, is a new phase in the development of the DS line. The innovative and visionary model fits perfectly with the brand's "Créative Technologie" baseline and features even bolder choices in style, architecture, sensations and refinement. The Citroën DS5 experience is about fully embracing the pleasure of driving an outstanding vehicle. A singular creation, the Citroën DS5 surprises and appeals with:

-its styling: boasting an audacious body and inspired style, the DS5 is an aerodynamic sculpture that expresses the finest in Citroën expertise. It features authentic materials including club leather and aluminium, together with unique upholstery such as the "watchstrap" seats that embody the finest in French-style luxury. Extraordinary, bewitching and attractive, the Citroën DS5 appeals, naturally.
-the intelligence of its design: the Citroën DS5 is an extraordinary vehicle that proposes a new take on the premium segment while combining compact body dimensions with a spacious interior. It goes beyond traditional compromises between aesthetics and user features, marrying driving pleasure with shared well-being.
-its technologies: it also features the finest Citroën technology, including intelligent traction control, a second-generation lane departure warning system, automatic activation of the high-beam function depending on surrounding traffic, head-up display in colour on a blade, and a reverse parking camera. The Citroën DS5 will also be the brand's first model available with Hybrid4 full-hybrid diesel technology, combining strong performance (200 bhp, four drive wheels) and all-new driving sensations (electric power in the city, acceleration boost in "Sport" mode) for CO2 emissions of just 99 g/km.
-its road performance: like the Citroën DS3 and DS4, the DS5 offers a dynamic yet serene drive in all circumstances. The car's unique road feel gives drivers the feeling that the wheels are at their fingertips.
-its spirit: with its strong emotional content, the Citroën DS5 invites passengers to take part in an amazing onboard experience, with a cockpit-inspired driver's station where dream and reality meet.

Technology for driving:
For stable and efficient road manners, the Citroën DS5 is fitted with electronic brakeforce distribution, emergency brake assist and ABS, as well as a new Citroën innovation, intelligent traction control, combined with ESP for optimum vehicle control in the most delicate driving situations..

The DS5 is also equipped as standard with the Citroën eTouch service to remain connected in all circumstances. eTouch is a secure and free system available 24/7 using a built-in SIM card, notably including localised emergency and assistance calls (depending on country) to get the emergency services to the car as quickly as possible in the event of an incident or accident. Citroën eTouch features two additional services via the web: a virtual maintenance manual, for alerts on mechanical or safety incidents and information on upcoming servicing, and an eco-driving service, for monitoring fuel consumption and CO2 emissions.

In true Citroën spirit, the DS5 is a concentrate of simply obvious technologies. It was designed with useful and intuitive innovation in mind to make driving easier. Together with tried and tested technologies such as hill-start assist, an electric parking brake, parking assist and a programmable speed limiter cruise control, the Citroën DS5 is fitted with:

-automatic high beam lamps. A miniature camera built into the interior door mirror processes the images received to manage the automatic high beam lights, switching them on and off as necessary, in line with ambient lighting and traffic conditions, for stress-free driving at night.
-a second-generation lane departure warning system, with enhanced predictive capabilities. Lane departures, signalled via a vibration in the driver's seat, are detected by a miniature camera built in to the rearview mirror and road-line recognition technology based on digital imagery. This technology is used to counter the problem of drowsiness at the wheel.
-colour head up display. A transparent blade, rising up when the car is started, projects essential driving information (speed, speed limiter-cruise control settings and navigation settings) in the driver's direct line of sight. For Hybrid4 models, when the vehicle is running without consuming fuel, the display changes colour from white to blue, encouraging an ecological driving style. Drivers are left to concentrate on the essential.
-reversing camera. Working with the MyWay navigation system, the reversing camera sends a colour image to the navigation screen. Using visual markers (red lines for the limits of the rear bumpers and blue lines for maximum wheel turn), drivers can manoeuvre their vehicles in complete safety.
-fog lamps with static cornering lights. This system adds an extra beam when cornering to increase visibility of the inner part of the bend or intersection by up to 75° to the left and right of the car. This equipment springs into action automatically when the driver uses his indicator or when the steering wheel turn exceeds 60°.
-hands-free access and starting. Drivers enter and start their vehicle with simple, intuitive actions while keeping the key on their person. The electronic key is detected when approaching the vehicle, the doors open and close with just the slightest brush against the handle, and the car starts with a simple push on the START button.
Dynamic road performance

The Citroën DS5 provides all-new driving sensations with a unique at-the-wheel experience combining dynamic handling and ride comfort:

The springing and damping settings provide a perfect "read" of the road while remaining easy to control. The dynamically tuned Citroën DS5 gives occupants the impression of being glued to the road while bringing passengers a feeling of safety in all circumstances.
- The precise and direct steering of the Citroën DS5 contributes to the car's dynamic feel. With hydraulic electric pump assistance, it offers a gradual and hearty response without being too delicate, especially on straight lines.
Lastly, along with active safety equipment (EBD, EBA, ABS, ESP, intelligent traction control), the Citroën DS5 has powerful brakes with a firm response, thanks in particular to 340 mm-diameter front brakes on most versions.
Four fuel engines

The third model of the DS line will be available on launch with two Euro 5 diesel engines equipped with particulate filters: the e-HDi 110 Airdream (EGS6), with new-generation Stop&Start micro-hybrid technology reducing CO2 emissions by up to 15%, and the HDi 160 (6 speed manual or 6 speed automatic), boasting remarkable performance for a pleasant and safe drive.

The Citroën DS5 is also powered by two turbocharged petrol powerplants with direct injection, both of them Euro 5 compliant and developed with BMW: the THP 155 (6 speed auto) and the THP 200 (6 speed manual). The THP 200 offers a remarkable drive with power of 197 HP and maximum torque of 275 NM at 1770 rpm.

The first Citroën with Hybrid4 technology

The DS5 is the first Citroën fitted with full-hybrid Hybrid4 technology combining the on-road performance of an HDi diesel and the efficiency of electric power. The system provides heady driving pleasure - with 200 bhp, four drive wheels, electric mode in cities, accelerator boost - along with extra low CO2 emissions, at just 99 g/km.

The originality of the Hybrid4 system lies in a blend of several technologies:

-a 2.0 HDi 160 DPFS internal-combustion engine,
-Stop&Start system with a second-generation reversible alternator,
automated 6 speed manual gearbox with optimised shifts,
-permanent magnet synchronous motor located on a special multi-link rear axle developing power of 37 HP,
-the Power Train Management Unit, which automatically manages the settings of the two engines with a view to reduced fuel consumption.

Hybrid4 technology offers several different driving settings. Using the thumb wheel on the central console, drivers choose from one of four modes: Auto, ZEV, 4 Wheel Drive and Sport.

-"Auto" is the default setting. To optimise fuel consumption it automatically handles switches between the fuel engine and the electric motor.
-"ZEV" (for Zero Emission Vehicle) is for driving with the electric motor only, for speeds of up to 60 km/h. Range in ZEV mode is between 2 km and 3 km, after which the car automatically switches back to "Auto".
-"4 Wheel Drive" is used when drivers need enhanced grip at low speeds. The front wheels are powered by the internal-combustion engine and the back wheels by the electric motor. Ideal for tough ground and low-grip situations such as snow, mud and sand.
-"Sport" provides extra responsiveness and vitality by making maximum use of the electric motor on top of the fuel engine. Accelerations and gear changes are revitalised by an electric "boost".
