Peugeot will show off the world’s first diesel full hybrid production car, based on the 3008 crossover, which at the Paris show in October.

The 3008 HYbrid 4 combines a two litre 163bhp HDi diesel engine and a 37bhp electric motor which return combined drive cycle fuel consumption figures of 74.4mpg and CO2 emissions of 99g/km.  

Peugeot said the diesel hybrid technology also brings a range of other benefits including excellent driveability and four different operating modes: zero emission vehicle, four wheel drive, automatic and sport.

In automatic mode the entire system is automatically controlled, including operation of the HDi diesel engine and the electric motor. This provides optimal driving for fuel consumption and performance.

ZEV is all-electric while four wheel drive mode instructs both power trains to operate together as far as possible; the rear wheels are driven by the electric motor and the front wheels by the HDi diesel engine to provide all terrain capability or to cope with snow.

Sport mode allows quicker gear changes at higher engine speeds for more dynamic performance.

The HYbrid 4 is also equipped with Peugeot's electronically-controlled six-speed manual gearbox for its engine management capabilities and ability to optimise fuel consumption. Environmental performance is improved further with a second generation stop/start system.

Changeover from the HDi diesel engine to the electric motor occurs automatically, due to a stop/start system which places the HDi diesel engine in standby and restarts it as and when conditions require.

The two power sources also complement each other in certain driving conditions – such as a 'boost' effect during hard acceleration, or when overtaking.

The electric motor and its ancillary equipment are fitted at the rear of the vehicle. This provides a number of advantages and helps reduce costs and optimise the production process.

Everything is controlled electronically with no mechanical links between the front and rear drivetrains which means there are no structural constraints affecting the layout and design within the passenger compartment.

The rear installation also avoids the need for any major redesign of the engine compartment while also improving weight distribution.

This architecture is achieved by means of the use of a simple and compact rear module containing the electric motor, its ancillary equipment and also the rear drivetrain and suspension.

The costs of the rear module are therefore reduced because of the technical possibility of deploying the same HYbrid4 technology into different market segments or different body shapes, regardless of the type of internal combustion engine.

PSA Peugeot Citroën teamed up with Bosch to develop the electric motor, power electronics, reversible high-voltage alternator/generator and other systems managing the dialogue between these components, the braking and trajectory correction systems (ABS and ESP). Sanyo provided the Ni-MH high-voltage batteries.

The 3008 HYbrid4 will be produced in Sochaux and Mulhouse and launched in spring 2011 in Europe.
