The adoption of electro-hydraulic power steering on the 407 1.6-litre HDi FAP plays a key part in improving its environmental efficiency. Its power steering is controlled by a hydraulic electro-pump unit in which assistance varies according to the speed of the car, the speed of rotation of the steering wheel and the temperature of the steering fluid. This steering system, already in place on other models in the 407 range (except for six-cylinder models), optimises fuel consumption compared to traditional hydraulic steering powered by the engine.

In addition, thanks to permanent adaptation of the force to be supplied, it offers the driver maximum steering accuracy as well as excellent feedback, while at the same time facilitating manoeuvres at low speed.

Another key factor: major engine recalibration work has been carried out on this 1.6-litre HDi unit to obtain a significant reduction of emissions. Lastly, this 407 is now equipped with new Michelin Energy Saver 205/60 R16 H tyres which significantly reduces rolling friction through its advanced tyre construction.

And because this adaptation to 129g/km of CO2 was obtained without any change to gear ratios, performance levels and acceleration are unaffected. With this improved specification, the latest 407 strengthens further its appeal to customer. In addition to its elegant and attractive appearance, still distinctive in its segment, the continuity of its residual value, its durability and its competitive overall operating costs, the 407 continues to be acclaimed for its excellent road holding and its undiminished ability to combine active safety, driving enjoyment with a high level of comfort and convenience.
