Efficient Modular Platform 2
The New Vehicle Platform by PSA Peugeot CitroŽn
Platform: definition and purpose
A platform is a modular vehicle base at the core of new model design and production.
A platform equipped with a powertrain represents 60% of a
vehicle’s production cost. It comprises all functions not specific to a
specific body style, including:
From this single platform, PSA Peugeot CitroŽn is able to develop a wide variety of body styles across several segments that are tailored to its different global markets. These include four and five door sedans, station wagons, MPVs, notchbacks, SUVs, cabriolets and coupťs.
Critical role in automobile manufacturing
The platform policy initiated by PSA Peugeot CitroŽn in 1998 makes it possible to produce a wide variety of models, accelerate launch schedules and optimise capacity utilisation.
Platforms play a critical role in:
In addition, platforms provide powerful leverage in terms of mass, consumption, quality and cost competitiveness.
PSA Peugeot CitroŽn’s current
Efficient Modular Platform 2 (EMP2): a new generation modular platform
The modular EMP2 platform will allow the Group to develop a diversified worldwide product line-up
The combination of advanced modularity and broad dimensional coverage allows for completely new combinations:
Operational in 2013, the new generation EMP2 platform is scheduled to gradually replace PF2 and PF3 by handling new C and D segment launches.
Ultimately, EMP2 is expected to cover half of Peugeot and CitroŽn vehicle sales worldwide.
EMP2 will enhance the competitiveness of new Peugeot and CitroŽn models thanks to:
EMP2 continues the drive to reduce the mass and CO2 emissions of future models
EMP2 focuses on slimming down future vehicles, with an exceptional average weight reduction of 70 kg for the platform’s technical aspects alone thanks to a virtuous product-process design featuring:
EMP2 also benefits from effective and efficient technological choices to reduce CO2 emissions. These include:
These efforts to achieve a significant reduction in weight and CO2 emissions will deliver an average 22% decline in fuel consumption for future EMP2 vehicles.
EMP2: a new platform to meet customer expectations
What isn’t visible has a major impact on what the customer does see.
Architecture and equipment choices for an even more attractive package of features
Whether to reduce vehicle weight (to deliver performance and driving pleasure) or to enhance features, PSA Peugeot CitroŽn has chosen exclusive architectures and innovative technologies for the customer’s benefit. These include:
New equipment and new processes also take the quality of Peugeot and CitroŽn vehicles to a higher level. Among them:
Responses to future styling trends are already in EMP2’s DNA
EMP2 offers new vehicle proportions and greater styling potential, with:
This move towards a more compact platform will offer appreciable flexibility for meeting future styling trends.
Impact on manufacturing facilities
Eight European production facilities involved
Process engineering for EMP2 is already completedat the Vigo and Sochaux assembly plants, which will produce the platform’s first two body styles.
Production has been launched in most of the upstream plants that manufacture pressed sections and mechanical components for suspension systems.
Sites directly concerned by the EMP2 platform in early 2013
Optimised body-in-white and assembly
The same versatile installations from one site to another
The virtually simultaneous launch at Sochaux and Vigo of two major body styles using the EMP2 platform has made it possible to take the variety of configurations offered by the platform into account from the beginning of the project and develop versatile processes for these variations that can be replicated at the different production sites.
Improved working conditions
Improving ergonomics and working conditions was a key concern throughout the project.
The most significant change concerns underbody work, which is one of the most strenuous parts of the assembly process.Above-the-head movements have been reduced by 80% by preparing parts in the mechanical area and docking them under the body during assembly.
Efficient Modular Platform - EMP2 summary
1. A modular architecture to meet the specific expectations of our main markets
From this single platform, PSA Peugeot CitroŽn will be able to develop a wide variety of body styles across several segments that are tailored to its different global markets. These include four and five door sedans, station wagons, MPVs, notchbacks, SUVs, cabriolets and coupťs.
2. Broad powertrain selection on a single platform
Four-cylinder, hybrid, and four-wheel drive powertrains will also be available on this platform.
3. Substantial reductions in mass and CO2 emissions:
CO2 emissions cut by 13 g, mass reduced by 70 to 80kg, one less full tank a month
Through the use of lighter weight, innovative materials such as steel, composites and aluminium for suspension systems, as well as cutting-edge processes like hot stamping and laser welding, EMP 2 will make it possible to reducemass and CO2, while improving rigidity, safety and driving pleasure. Thanks to the potential of SCR technology to reduce NOx emission levels, EMP 2 is technically Euro 7 compliant.With these low-carbon modules, PSA Peugeot CitroŽn is strengthening its CO2leadership.
4. Innovative technological choices to support the upmarket strategy for future Peugeot and CitroŽn models
With solutions ranging from composite floors to ultra low rolling resistance tyres, EMP 2 will allow the Group to offer vehicleswith the most up-to-date equipment and features (new suspension systems, smooth steering and nimble handling, passenger compartment comfort, enhanced safety, etc.).
5. Greater stylistic freedom
EMP 2 offers greater flexibility to respond to new styling trends such as large wheels on all four corners, low body styles and low ride heights, regardless of the model (SUV, sedan etc.).
6. Global deployment
This new modular platform will develop a diversified product line-up and will cover 50% of the Group’s production volumes worldwide.
The assembly plants in Vigo (Spain) and Sochaux (France) will produce the first two body styles built on this platform as from early 2013.The platform will be deployed a year later in Wuhan, China.
7. Eight European sites will be involved in the creation of the platform
No fewer than eight of the Group’s European sites are involved in the deployment of the EMP 2 platform.
The different components for the creation of the platform are produced in several of the Group's plants:
8. Manufacturing flexibility: the same versatile installations at sites around the world
For example, at a mechanical component plant, rigid and rubber-mounted subframesare assembled on identical modules, one in Caen, the other in Mulhouse.
For body-to-white, different versions can be produced in the same streams without needing specific installations for either version.
9. Improved working conditions
Above the head movements will be reduced by 80% and there will be a substantial reduction in the number of “heavy” workstations (underbody operations kept to an absolute minimum).
10. Capital expenditure
€630 million has been invested to develop this platform
