Europe: Peugeot 4007 DCS

[B]Dual Clutch System (DCS)[/B]

To meet the increasing expectations of customers in terms of versatility and driving pleasure, the 4007 makes use of its new gearbox with cutting-edge technology; the Dual Clutch System.

This technique consists of automating the gear changes on a manual gearbox and using two clutches to transmit the engine torque. The first clutch is located on the even-numbered gears while the second clutch is fitted to the odd-numbered gears.

A fine-tuned electronic management system anticipates the gear changes and hydraulically operates one of the two clutches, which operate in parallel, within a few tenths of a second without a torque converter. As such, one shaft is always connected and changing from one gear to another takes place in just a few tenths of a second, resulting in exceptionally smooth driving. Gear changing is quick and smooth with no interruption in the supply of torque.

The semi-automatic gearbox chosen for the 4007 is equipped with six speeds to make best use of the performance from the 2.2-litre HDi FAP 156 bhp engine. The choice of wet clutch technology has been favoured to transmit the generous amount of torque produced by this engine (380Nm at 2000rpm).

A versatile gearbox, the DCS 6-speed box can be managed in two ways: in automatic mode with two operating programmes (Drive or Sport) or in semi-automatic mode (Sequential) by using the gear selection paddles located behind the steering wheel.

The DCS 6 has the advantage of an adaptation program for slopes or inclines. The computer (ECU) authorises engine braking power according to the contours of the road to augment smooth driving. In the same vein, hill start assistance is another feature, derived from the ESP system; it automatically holds the vehicle for a few seconds to assist the vehicle in pulling away from a start.

[B]The assurance of a dynamic and responsible SUV[/B]

The latest generation 2.2-litre HDi FAP 156 bhp engine that powers the 4007 with the DCS automatic is in keeping with the concept of efficient environmental performance.

The 4007 2.2-litre HDi FAP DCS automatic performs very favourable results in terms of energy consumption versus performance and services delivered (on-demand four-wheel-drive, seven seater on all DCS models) to confirm that it really is possible to combine dynamism and automation with environmental efficiency:

* 6.1 liters/100 km on the Combined Cycle
* 192g/km CO2 (the manual version produces 191g/km CO2)
