Peugeot 407 1.6 HDi
Following on from minor revisions last July which included the addition of the 2.0-litre HDi FAP Euro 5 specification engine which is capable of 50.4mpg – 150g/km of CO 2 , Peugeot have now added a revised 1.6 litre HDi engine which enables the 407 to duck under 130g/km for the first time thanks to a Combined fuel economy of 57.6mpg with CO 2 emissions of 129g/km.
The significant reduction in CO 2 emissions has been achieved through a major engine recalibration carried out on the 1.6-litre HDi FAP unit. Unlike most low CO 2 cars achieving 129g/km of CO 2 has been obtained without any change to gear ratios, so performance levels and acceleration remain unaffected.
Another supplementary contribution to the HDi 110 engine’s fuel efficient behaviour is the adoption of electro-hydraulic power steering. The 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 and the temperature of the steering fluid.
This steering system, already in place on other models in the 407 range (except six cylinder models), optimises fuel consumption compared to traditional hydraulic steering powered by the engine. The system can vary the assistance provided which Peugeot claims enables ‘excellent feedback’ at higher speeds whilst still providing light steering at low speeds. Finally, the latest 407 is now equipped with new Michelin Energy Saver 205/60 R16 H tyres which significantly reduce rolling friction through advanced tyre construction.
Prices for the 407 Saloon start with the ‘S’ trim 2.0-litre Bioflex petrol at £17,745. The1.6-litre HDi 110 (129g/km) is an additional £1,000 at £18,745. The business ‘SR’ model with Peugeot Connect Navigation, 16” alloy wheels and Bluetooth hands-free telephone is £1,000 above the ‘S’. The higher specification ‘Sport’ model features half-leather upholstery, front and rear parking aid, automatic folding mirrors, automatic windscreen wipers, and automatic headlamps on. Dual zone climate control air conditioning and 18” alloy wheels, with the HDi 110 engine is available at £20,745.
