Peugeot is moving forward with the plan to stick a 1.6-liter diesel engine into the 407. With low-rolling resistance tires and a "major engine recalibration," the new 407 drinks 4.9 l/100 km of diesel (48 mpg U.S.) on the Combined cycle and emits 129 grams of CO2 per kilometer and power of 110bhp. That we knew. Peugeot announced today that the more powerful 2.0-litre HDi FAP engine also offers lower fuel consumption (42 mpg, with 150g/km of CO2 emissions) while putting out 140bhp. The HDi 110 1.6L gains some efficiency through the use of an electro-hydraulic power steering system that removes a bit of strain from the engine, which powers traditional hydraulic steering systems. A 2.0-litre Bioflex petrol engine is also availabe in the 407. More details after the jump.

PRESS RELEASE:

PEUGEOT 407 – NOW WITH NEW 1.6-LITRE HDi 110, LOWER CO2, IMPRESSIVE ECONOMY AND EXTRA STANDARD EQUIPMENT

* New enhancements, lower CO2 emissions of 407 models below 130g/km
* New HDi 110 has greater economy and lower CO2
* Features Michelin Energy Saver tyres for lower rolling resistance

The new 407 continues to improve following new features introduced last July on both the 407 Saloon and SW, to its style, robustness and high quality. These combined enhancements to interior comfort and equipment (front parking assistance, new Peugeot Connect (RNEG) navigation and Connect Media (RT5) navigation systems) included the arrival of the latest 2.0-litre HDi FAP Euro 5 specification engine, capable of 50.4mpg, 150g/km of CO2 with power increased to 140bhp. Latest versions of 407 now benefit from a multitude of further technical developments - all designed to enhance the overall driving enjoyment - that include a revised 1.6-litre HDi 110bhp engine with a Combined fuel economy of 57.6mpg with CO2 emissions of 129g/km.

A key factor that ensures efficient optimisation is the major engine recalibration carried out on the 1.6-litre HDi FAP unit to obtain a significant reduction of emissions. Achieving 129g/km of CO2 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. In addition, due to the 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. 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.

With this improved specification, the latest 407 further strengthens its customer appeal by combining performance with economy and lower taxation. 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 and driving enjoyment with a high level of comfort and convenience.

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 just £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.
