Citroën will offer the e-HDi micro-hybrid system as an option on the new DS4, to be revealed at the 2010 Paris Motor Show; the DS4 is expected to go on sale later in 2011.
DS4 will be launched with a choice of five Euro 5 engines. The two HDi diesels—an HDi 110 (available as an e-HDi version) and an HDi 160—are both fitted with Citroën’s Diesel Particulate Filter System. The three gasoline powerplants—VTi 120, THP 155 and the new THP 200—were co-developed with BMW. 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:
- the engine;
- 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; and
- an electronic gearbox system (EGS) with optimized 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.
Hybrid cars is provided better mileage. I think hybrid car is better than electric cars. Hybrids help reduce the dependency on fossil fuels which directly affects fuel prices.

If you want technology to be introduced rapidly, you have to start with a small increment that is simple enough. Then, the evolution towards more complex solutions that have greater potential to reduce fuel consumption will follow automatically. Toyota Prius was the opposite. They tried to take a couple of giant leaps at once. After more than 10 years, hardly anyone has followed this path. In just a few years, every car will have start-stop and a number of the other features mentioned the article. The total gain in fuel savings will be much higher with these measures than all full-hybrids together. Eventually, full hybrids might take over but I am afraid that we will have to wait for a very long time before that happens.
