Beginning in June 2006 (and depending on the country), the C4 will be available with a new gearbox: the six-speed electronic gearbox system (with the six-speed electronic gearbox system). In combination with an HDi 110 DPFS diesel engine it gives the C4 a high level of driving comfort and pleasure for a vehicle of this category while at the same time reducing fuel consumption.

Its use in the Citroën C4 hatchback and coupé underlines the novel concept of this model, which rapidly established its position in the mid-range market by offering innovative equipment for more safety, ease-of-use and driving comfort. Since its launch in October 2004, more than 350,000 C4 have been sold worldwide.

The 6-gear electronic gearbox system gives the driver of the C4 a totally new driving pleasure, due to the various ways of shifting gears (paddles behind the steering wheel, sequential shift lever or automated mode) and the absence of the clutch pedal.

By means of automating gear changes and clutch control, this new gearbox obtains a reduction of fuel consumption on the order of 3 to 5% in comparison to a conventional manual gearbox. Fuel savings are boosted by the presence of a 6th gear.

Due to its particularly fuel-efficient engine, the C4 HDi 110 DPFS with the six-speed electronic gearbox system thus brings fuel consumption down to 4.5 litres per 100 kilometres in a combined cycle, with CO2 emissions of 120 grams per kilometre.

The six-speed electronic gearbox system offers outstanding user comfort and responsiveness to the driver's commands. Its electro-hydraulic control system ensures smooth and lightning-fast gear changes in a wide range of transmission ratios, which makes driving with this gearbox particularly pleasant.

The new gearbox permanently adapts to the driver's behaviour and reinforces his driving sensations in sports mode, which makes gear changes even faster. It also offers him peace of mind and driving comfort with the hill-hold control and easy acceleration dosage when manoeuvring, particularly in reverse.

The six-speed electronic gearbox system offers a real alternative to conventional automatic or manual transmissions - by the driving pleasure it procures as much as by the fuel savings it generates and its attractive price.

This new gearbox expands the offer of automated manual gearboxes already available in the Citroën range. These are proposed in combination with petrol and diesel engines in the C1, C2, C3 and C3 Pluriel models. Since its introduction in 2002, 130,000 of these subcompacts were sold with the automated manual gearbox SensoDrive.
