Citroën has released first details about the new DS4, which will be available with new e-HDi drivetrains for improved fuel economy and lower CO2 emissions.
The DS4 will be launched with a choice of five Euro 5 engines. The two HDi diesels – a HDi 110 (also available as an e-HDi version) and a 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 – has a power output of 147kW and torque of 275Nm at 1,700rpm – with CO2 emissions of just 149g/km. All engines are available with manual or EGS six-speed gearboxes.
The 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:
* a 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
* 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.
Citroen says that around 15% of the 200kg of plastic used in the DS4 is derived from ‘green materials.’
The Citroën DS4 will be revealed at the 2010 Paris Motor Show and is expected to go on sale later in 2011.
