As the European leader in 2012 with CO2 of 121.5g/km, in 2013 PEUGEOT is reducing the weighted average emissions of CO2 of its European range still further. At the end the May this stood at 116.3g/km. New technologies will allow us to achieve the ambitious CO2 policy target of 95g per kilometre on the weighted average of the new vehicles sold in Europe in 2020, offering particularly economical engines with fuel economy of 141mpg achievable.

HYbrid Air combines petrol and compressed air in a full hybrid solution. The simplicity, durability and international nature of this technology make it potentially available to the largest audience of consumers. HYbrid Air is a key step in reaching the target of getting over 140mpg.

208 HYbrid FE is another highly innovative technological solution to improve fuel economy. This non Plug-in petrol full-hybrid concept explores many new technologies in partnership with Total, to combine driving pleasure and efficiency with low CO2 emissions and fuel economy.




208 HYbrid FE: technology to achieve in excess of 140mpg

In partnership with Total, this non Plug-in, petrol full-hybrid is part of marque's hybrid strategy.

HYbrid4, the diesel-electric hybrid, has already won over 28,000 customers in Europe with its high-level performance. 208 HYbrid FE explores technological solutions and takes the results even further to achieve record fuel economy using: aerodynamic properties, weight reduction, power train and hybridisation.

A historic partnership

Since 1995, PEUGEOT and Total have been working together to significantly reduce fuel consumption, CO2 emissions and TCO (Total Cost of Ownership) of vehicles.

First shown at the Geneva Motor Show 2013, the aim of the 208 HYbrid FE is to combine real driving pleasure with low CO2 emissions. More precisely, the intention is to halve the CO2 emissions of the cleanest 208, equipped with a 1.0-litre VTi 68bhp yet to provide it with the acceleration of a performance hatchback, like the 208 GTi. A real challenge!

Numerous innovations are implemented in several areas:

Aerodynamic properties: gain of 25%,
Weight reduction: 20%,
Power train: 10% reduction in consumption,
Hybridisation: recovery of 20% of the energy over one cycle.
Aerodynamic properties: gain of 25%

The aerodynamics experts took the Peugeot design and pushed it to the extreme. The Cd is improved by 25%, to a value slightly lower than 0.25, while keeping the passenger and boot compartments unchanged. This performance is achieved in particular by means of components which can be seen from the outside: flat underside, rear diffuser, rear tracks narrowed by 40mm, mirrors eliminated and Tall & Narrow tyres. The size of the radiator grille is also reduced by 40% by means of the progress made on the drivetrain.

Weight reduction: 20%

The 208 HYbrid FE benefits from the expertise of the Polymers Division of the Refining-Chemicals branch of Total, as well as of its two subsidiaries CCP Composites and Hutchinson, in the field of composite materials. These are used extensively to reduce weight by 200kg: with a one-piece shell, under-floor panel, doors, lower front panel, bonnet and wings. They are also used in the passenger compartment: door trim pads, centre console and vent trims.

The Pseudo MacPherson suspension innovates with a composite blade fitted in a transverse position, which replaces several parts: suspension springs, lower wishbones and an anti-roll bar.




Power train, consumption reduced by 10%

The latest generation 3-cylinder engine evolves in combination with a battery and an electric motor taken from PEUGEOT Sport's Endurance programme.

The efficiency of the petrol engine (68bhp - 50kW) uses the volume of fuel made available to its full potential. The Miller Cycle is optimised and the compression ratio changed to 16:1. Friction losses are reduced by 40% thanks to special reciprocating gears: surface coating, design, balance. The 1.2-litre VTi-FE engine is also modified as regards cooling, towards a minimum of thermal inertia: light engine, less than a quarter of the previous volume and flow of coolant.

The greasing of the EGC (Electronic Gearbox Controlled) manual gearbox, which is standard, is redesigned to reduce the volume of lubricant and prevent splashing of the gears, which consumes energy.

Total Lubricants has developed a prototype oil, offering a friction reduction of 3%, as well as greases for the driveshafts and their homokinetic seals. The high performance oil, of grade 0W12, develops its properties very rapidly with a shorter temperature rise time. Optimised as regards friction, it retains, both when hot and when cold, an advantage compared to the best products on the market.

Hybridisation, 20% of the energy recovered over one cycle

The gearbox design is specific with the electric motor fixed to the differential crown wheel. The arrangement permits the provision of reverse gear, by inverting the direction of rotation and of the starter function while also providing purely electric ZEV (Zero Emissions Vehicle) driving. The electric motor combines power and lightness (only 7kg), it develops 30kW as a motor and 100kW as a brake.

During the deceleration phases, whether this is on releasing the accelerator pedal or on braking, the vehicle is slowed down preferentially by the electric motor. The hydraulic circuit only comes into operation at the end of braking. During this phase, the electric motor operates as a receiver to recover the energy and charge the Lithium-ion battery. Then, on acceleration, this energy is returned and assists the petrol engine.
