Compact and muscular, the DS signature on the bonnet is complemented by a striking LED light signature around the front fog lights. The LEDs are illuminated both day and night. The eye-catching profile, featuring a chrome-finished waistline surrounding dark tinted windows, is enhanced by muscular wheel arches that emphasise the large wheels (up to 19 inch) and is crowned by a tautly drawn roofline with a spoiler for added vitality. The lower part of the rear bumper is finished in chrome and the horizontal detailing on the rear light clusters highlights their innovative boomerang design.
Combining coupé style with 2+2 door practicality, DS4 offers three full-sized rear seats, accessed by rear doors with hidden handles that are seamlessly integrated into the body's flowing lines. DS4 also benefits from a 370-litre boot and a host of clever storage solutions.
DS4's cabin is dominated by the large panoramic windscreen that extends backwards into the roofline. Offering up to 45° of upward vision, the panoramic glazed area combines with DS4's slightly raised stance, to provide optimised visibility for the driver, with a bright yet intimate, airy cabin environment for passengers.
Allowing owners to personalise the interior, DS4 is available with a choice of five leather combinations, including two-tone options. Range-topping models are also equipped with high quality leather on the dashboard and door panels, complete with a 'Bracelet' design on the seats, evoking the links of a watch strap.
Depending on trim level, DS4 is fitted with large-diameter (340mm) ventilated disc brakes and, as standard, with dedicated braking control systems, including ABS with Electronic Brakeforce Distribution (EBD) and Emergency Brake Assist (EBA). Ensuring optimal vehicle control in the most demanding driving situations, DS4 also features traction control with ESP.
DS4 will be launched with a choice of five engines. The two HDi diesels, an HDi 110 (also available as an e-HDi version) and an HDi 160, are both fitted with Citroën's Diesel Particulate Filter System. The three petrol powerplants, VTi 120, THP 155 and the new THP 200, were co-developed with BMW. The new THP 200, based on the 1.6-litre engine, delivers flexible power delivery and performance thanks to its power output (147 kW), plentiful torque (275 Nm at 1,700 rpm) with low CO2 emissions of 149 g/km. All engines are available with manual or EGS six-speed gearboxes.
DS4 can be specified with Citroen's micro-hybrid e-HDi technology, which is available from launch on versions powered by the HDi 110 engine. The e HDi system comprises of:
- an economical HDi Euro 5 diesel power plant
- a new generation Stop & Start system, which instantly cuts out the engine when the car comes to a halt (red lights, traffic jams).
- a second-generation reversible alternator and an e-booster function that restarts the engine instantly (0.4 seconds)
- an electronically controlled alternator that recovers energy during braking;
- an Electronic Gearbox System (EGS) with optimised gear changes.
All required features such as the radio, air-conditioning and steering functions remain in operation when the engine is stopped by the system. This technology can reduce the fuel consumption and CO2 emissions by as much as 15% in built-up urban environments.
