By launching the world’s first diesel full hybrid vehicle -
the 3008 HYbrid 4 - Peugeot will be writing a new chapter in motoring history. The combination of a fuel
efficient 2.0 litre 120 kW (163 bhp) HDi diesel engine and a 27 kW (37 bhp) electric motor is the optimal
combination for a hybrid vehicle. Unlike previous hybrid vehicles which use a less fuel efficient petrol
engine, the Peugeot 3008 HYbrid4’s diesel engine provides superior Combined Drive Cycle fuel consumption
of 3.8 litres/100 km (74.4 mpg), and CO2 emissions of 99 g/km.
The use of diesel hybrid technology also brings a range of other benefits:
- High performance combined with excellent driveability
- Freedom and simplicity of use with the possibility of choosing four different operating modes: ZEV
(Zero Emission Vehicle), Four-wheel drive, Auto and Sport
- Silent operation, when driving in electric only mode
- Peace of mind offered by the safety inherent in a four-wheel drive vehicle
- Environmental friendliness with CO2 emissions from 99 g/km
The Peugeot 3008 Hybrid4 is designed to appeal to demanding, 'technophile' customers who are in search
of a rewarding and original vehicle.
In terms of performance, the Peugeot 3008 HYbrid4 benefits from the combined power of the HDi diesel
engine and electric motor during acceleration and when an immediate surge of power is required (the
"boost" function). The maximum combined power output is 200 bhp, 163 bhp from the 2.0 litre HDi FAP diesel
engine and 37 bhp from the electric motor. A maximum torque of 500 Nm is available, split with 300 Nm at
the front from the HDi diesel engine and 200 Nm at the rear generated by the electric motor.
To manage all the available performance a control selector mounted on the centre console enables the
driver to choose between four different operating modes.
- “Auto” 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 dynamic
performance
- “ZEV” mode (Zero Emission Vehicle) provides access to an extensive all-electric mode.
Activation of the HDi diesel engine is programmed to coincide with only more sustained phases of
acceleration. This requires the high-voltage batteries to be sufficiently charged and turns the vehicle
into a “city run-around” par excellence due to the total absence of noise and emissions.
- Four-wheel drive mode (4WD) 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. It offers
peace of mind, safety, improved driveability and accentuates the vehicle’s dynamic character. At low
speed it allows "all-terrain" capabilities equivalent to those of an SUV. The driver will, therefore, no
longer be concerned by the prospect of a slippery track or a snowbound uphill drive to a ski resort
- Sport" mode favours quicker gear changes at higher engine speeds than normal mode. In this
mode, the notion of “controlled power” comes into its own, coupling the diesel engine with the electric
motor provides more dynamic performance, optimally distributed and transmitted to the road by the four
wheel drive for a level of stability and driveability that will appeal to motoring enthusiasts.
With the Peugeot 3008 equipped with HYbrid4 technology, the aim is to appeal to customers who expect
both environmental-friendliness and technological sophistication, and also genuine driving enjoyment.
Indeed, as well as the social benefit of the steep reduction in fuel consumption, the level of
performance provided by this technology will delight even the most demanding customers in terms of road
holding, responsiveness, driveability, peace of mind regardless of road conditions and the possibility
of enjoying silent operation in town in the all-electric mode.
HYbrid4 technology brings together Peugeot’s best technologies and experience: HDi diesel engines,
electric vehicle knowledge, second-generation Stop & Start and electronically-controlled sequential
manual gearboxes.
The “hybrid” power train simply combines an HDi diesel engine and an electric motor. With their
exceptional efficiency, HDi diesel engines are thermodynamically more efficient than a petrol engine and
offer a 30% reduction in fuel consumption. Clearly the HDi diesel engine is the best internal combustion
engine choice.
For the “electric” component, Peugeot has historical expertise in the field of electric vehicles. To
date, the 106 Electric, marketed between 1995 and 2003, remains the world’s best selling zero emissions
car (in total nearly 10,000 vehicles were produced). At the end of 2010, Peugeot will become the first
to launch a latest-generation 100% electric vehicle in Europe, the Peugeot i0n (Peugeot's version of the
Mitsubishi iMiEV).
Pursuing the common sense approach of capitalising on the best existing components and expertise, it
was only natural to use Peugeot’s electronically-controlled 6-speed manual gearbox, not only for its
engine management capabilities but also for its ability to optimise fuel consumption. To improve
performance even further a second-generation STOP & START system is also used.
The choice of hybrid architecture was also guided by the search for optimal efficiency and consistency.
Hybrid technology uses two powertrains which can operate alternately or simultaneously:
- The HDi diesel engine operates in its most optimal operating window on longer, out-of-town journeys. A
diesel engine still remains the most efficient and versatile choice to power any vehicle
- The electric motor takes over from the HDi diesel engine in phases of lower power demands, particularly
when pulling away, driving at low speed and decelerating (for energy recovery). These are precisely the
features that characterise urban driving
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
operation of the accelerator pedal, low battery charge level, etc…).
The two power sources also complement each other in certain driving conditions ("boost" effect during
hard acceleration, or when overtaking another vehicle, for example). The performance of the HYbrid4 is
therefore directly comparable to that obtained with a single HDi diesel engine of a much higher capacity,
with good levels of responsiveness backed by a real breakthrough in terms of reduced fuel consumption and
CO2 emissions (around 35% less in the combined cycle for equivalent performance).
The electric motor and its ancillary equipment (inverter, converter, etc) are fitted at the rear of the
vehicle. This provides a number of advantages not only in terms of customer benefits and it also helps
reduce costs and optimise the production process.
The original layout of the Hybrid4 system allows for the possibility of four-wheel drive. The HDi
diesel engine drives the front wheels, while the electric motor (in the rear drive train) drives the rear
wheels.
Everything is controlled electronically ("by wire") and there are no mechanical links between the front
and the rear drivetrains. This gives the system many advantages over a "traditional" mechanical system.
- No structural constraints affecting the layout and design within the passenger compartment
- 4x4 and environmental-friendliness are no longer contradicting terms
The installation at the rear, of all the vehicle’s “electrical components”, has further technical and
economic benefits.
Firstly, it avoids the need for any major redesign of the vehicle’s engine compartment, while also
improving weight distribution. It also leaves intact the possibility of using a range of different
capacity engines, for possible future introduction.
Secondly, 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 drive train 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, in different body shapes, etc…, regardless of
the type of internal combustion engine used.
A real breakthrough in terms of reducing fuel consumption and CO2 emissions, while improving dynamic
performance levels, providing four-wheel drive and an electric only mode, HYbrid4 technology brings a
number of benefits without compromises.
Furthermore, the driveability, safety and eco-efficiency of the system are based on simple, reasonable
and consistent technological choices.
The Peugeot 3008 Crossover was chosen as the first application of this innovative technology.
The Peugeot 3008 HYbrid4 – In Detail
2.0 litre HDi FAP 163 bhp diesel engine
With a capacity of 1,997 cm³, this Euro 5 engine develops a maximum power of 163 bhp at 3,750 rpm and
a maximum torque of 300 Nm at 1,580 rpm. To obtain this level of performance it uses Peugeot’s latest
generation ECCS (Extreme Conventional Combustion System) combustion chamber design, a variable-geometry
low-inertia turbocharger, a high-pressure injection pump allowing a maximum pressure of 2,000 bar and
solenoid injectors with eight apertures.
Naturally this is combined with the latest generation "octosquare" Eolys additive-enhanced diesel
particulate emission filter (FAP) system.
Electronically-controlled 6-speed manual gearbox (BMP6)
The HDi diesel engine is matched to an electronically-controlled manual six-speed sequential gearbox:
- In automatic mode its electronic control helps provide significant savings in fuel consumption,
compared to a traditional automatic gearbox or even a traditional manual gearbox
- It offers real driving satisfaction derived from the possibility of choosing the gear change mode at
any time - manual or automatic - with either the gear lever or via controls behind the steering wheel
The gear change quality of the gearbox has been enhanced with HYbrid4 technology, as the rear electric
motor is activated during gear changes to improve the smoothness of the operation, and sustains drive in
between gear changes.
Latest-generation STOP & START system
This system places the HDi diesel engine in standby when the vehicle is at a standstill (at traffic
lights, a stop sign or in a traffic jam, etc) and when the vehicle is being driven in electric-only mode. It
significantly reduces fuel consumption and emissions in urban driving conditions while also enabling.the HDi
diesel engine to be restarted instantly and smoothly, when required.
The "high voltage" STOP & START system has a maximum output of 8 kW and can generate enough energy to
supply the power requirements for the rear electric motor if required (four-wheel drive mode).
Rear suspension
To ensure a dynamic performance on a par with Peugeot’s reputable road holding standards, the rear
electric module also includes a multi-arm rear suspension within which are housed the electric motor and the
reduction gearbox.
ESP
The ESP system fitted to the 3008 HYbrid4 incorporates an “improved traction control system” (ASR) able
to exploit the car’s four-wheel drive capabilities to the full on challenging surfaces. The performance of
the system can be enhanced by the fitment of optional 16" ‘Mud & Snow’ tyres.
Electric motor
The synchronous permanent magnet electric motor is located at the rear of the vehicle. It provides a
constant 27 bhp, with a peak output of 37 bhp. It generates a constant torque of 100 Nm, or a peak of 200 Nm
when necessary.
PTMU (Power Train Management Unit)
The PTMU is the electronic control unit that automatically manages the different operating modes of the
HDi diesel engine and the electric motor, programmed to optimise fuel consumption.
An inverter and a converter are used to control the electric power. The inverter controls the torque of
the electric motor by regulating the electrical current supplied from the high-voltage battery pack. It
operates in a voltage range of between 150 and 270 volts. The converter reduces the 200 volts from the
high-voltage battery pack into 12 volts to supply the vehicle’s onboard systems.
On the Peugeot 3008 HYbrid4 all these components have been made as compact as possible to optimise the
installation and weight effect in the vehicle.
High-voltage battery pack
The Ni-MH (Nickel Metal Hydride) batteries are located under the boot floor, near the electric motor.
The high-voltage battery pack is in addition to the standard 12V battery under the bonnet, which carries on
performing its normal duties.
In the medium term, this battery technology remains the most appropriate in terms of cost and
industrialisation for vehicles produced in large volumes.
Energy recovery
An energy recovery system (the electric motor becomes a generator) enables the kinetic energy provided by
the vehicle to be transformed into electrical energy to recharge the Ni-MH batteries during deceleration
(release of the accelerator pedal and during braking). This recovery system enables the driver to re-deploy
the "free" (Kinetic) energy to reduce fuel consumption accordingly.
Man-machine interface
A 7" 16/9 colour screen or a multi-function display, according to the car’s specification, informs the
driver in real time of the operating status of the hybrid power train. It also shows, for a given journey,
operating times in different modes and the status of the battery charge.
On the instrument panel the left-hand dial indicates the percentage of power used or recovered during
phases of braking or deceleration. Different scales indicate the battery status: Charge, Eco (optimal
operating range), Power, Boost (maximum use jointly with the HDi diesel engine).
Suppliers
To develop its HYbrid4 technology, the PSA Peugeot Citroën Group has teamed up with suppliers offering
the best expertise in each field. Based on the manufacturer’s technical specifications, BOSCH has provided
its expertise with respect to the electric motor, the power electronics, the reversible high-voltage
alternator/generator and other systems managing the dialogue between these components, the braking and
trajectory correction systems (ABS and ESP). Similarly, SANYO has provided its extensive knowledge in the
field of Ni-MH high-voltage batteries.
A distinctive design
The new Peugeot 3008 HYbrid4 is distinguished by its cutting-edge technology, combining responsible
driving and driving enjoyment, but also by its specific styling.
At the front, Peugeot’s latest design cues have been adapted to match the 3008’s generous dimensions and
to mark a break with existing models. The headlamps now have an integral bar of LEDs providing a daytime
lighting function and accentuate the 3008’s appearance. The 3008 HYbrid4 also wears the marque’s new Lion
badge on its bonnet.
At the rear, the rear spoiler has a two-tone finish with a high gloss black section, helping to
differentiate it from the other 3008 models in the range, as do the chrome badges which decorate the sides
and rear of the car.
Interior
Inside its roomy architecture, the driving position bears all the hallmarks of a top-of-the-range
vehicle, or even that of an aircraft cockpit. An expansive fascia panel, controls within easy hand’s
reach and an ergonomic centre console clearly separate the territory of the “pilot”. Combined with a
raised and dominating driving position it has everything in place to reward its drivers and offer a
range of new driving experiences not previously found in a conventional hybrid vehicle.
Distinctive materials are deployed throughout to accentuate the Crossover feel and explore new
avenues of expression. This is true in particular of the new and specific Guérande & Tramontane
two-tone leather finish which subtly combines bright pale grey on the seat cushions with a black finish
on the sides of the seats.
The gear lever with its modern and elegant design is a key feature of the HYbrid4 technology. It
enhances the technological ambience in the same way as the 7" colour display which provides information
on the flow of energy. A specific steering wheel bearing the signature HYbrid4 adds a touch of exclusivity
to the car.
“Multiflex” interior
Due to its intelligent “Multiflex” interior and clever integration of the batteries and the innovative
rear suspension, the Peugeot 3008 HYbrid4 can also be transformed to offer a considerable load capacity
under the parcel shelf of 420 litres (362 dm3 VDA), with 66 litres (29 dm3 VDA)
available under the boot floor.
The split lower tailgate opens to reveal a boot with a flat floor equipped with longitudinal securing
rings that exude quality and strength. From the boot, a rear seat folding system, controlled by switches
mounted on the load area side trims, allow the seats in the second row to be folded automatically, ‘as if
by magic’.

Combined with the folding front passenger seat, the Peugeot 3008 HYbrid4 offers a perfectly flat floor
from the tailgate to the fascia panel. This frees up a gigantic 1,501 litre compartment that is easy to
load.
Driving aids:
Comfortably seated behind the steering wheel, drivers will note among the equipment at their disposal
certain references to the world of aviation.
For example, to ensure that the driver never needs to take an eye off the road ahead, and as in a jet
aircraft, essential driving information is projected onto a retractable transparent panel which cleverly
extends from the instrument panel. The Head-Up Display system can be adjusted by means of toggle switches.
These switches, located above the centre console, add a further touch of style to the in-car ambience.
They also control another original item of equipment - the Distance Alert system. As its name implies,
this function helps the driver to keep aware of the safe distance from the vehicle in front, according to
the 3008’s speed.
Another item of equipment that helps to ensure maximum driving convenience is the Parallel Park Assist
(PPA). This system assesses the size of a space during parking manoeuvres and determines the possibility
of parking in it.
Similarly, the electric handbrake coupled with the Hill Assist function, helps the driver during
manoeuvres but also optimises the interior space within the vehicle.
Finally, a latest-generation satellite navigation system helps to guide users on their travels.
The Peugeot Connect 3-D Media Navigation (NG4) includes all the benefits of the marque’s existing
satellite navigation systems. These include a juke-box function, linked to a hard disc, Peugeot Connect
services, GSM function, a USB connector, a DVD player, a Bluetooth® system and a display which shows
specific buildings in full 3D.
The Peugeot 3008 HYbrid4 is a Crossover with an exceptional technological content offering unique
versatility and safety, unrivalled driving enjoyment and CO2 emissions of a very low level. Peugeot’s
choice of the diesel hybrid demonstrates that it is possible to combine uncompromising environmental
demands with driving experiences not previously available in a hybrid vehicle.
The Peugeot 3008 HYbrid4 will be produced in France (in Sochaux and Mulhouse) and marketed in the
northern spring of 2011 in Europe.
