Published on

This presentation analyses the Volkswagen group platform strategy/policy to reduce cost and time to market:
- Platform concept – design and process as defined by Volkswagen group.
- Volkswagen Group Platforms – Platform policy, production data, by segment and model family, with a forecast until 2017
- Standardisation to reduce cost – concept, scaling process, parts and tools standardisation.
- Advantages and dangers of a modular construction.

The Automotive Modular Design - Volkswagen group platform strategy/policy

  1. 1. The Automotive Modular Design An innovative approach to reduce cost and time to market A thinking based on the Volkswagen group platform strategy/policy Michel Costes President Jamel Taganza Vice-President Jean-Michel Prillieux Market director
  2. 2. Introduction Automotive industry is a very competitive one. Competition has still increased over the last 10 years with an enhanced globalisation. In order to face this competition, carmakers:  Develop their offer by: • Adding versions to their range of models (e.g. SUV, crossovers, …) • Adapting the design of the cars to the specific demand of the different countries where they sell their products.  Decrease the cost of their products by: • De-contenting them every time that the de-contented products are sufficient for the targeted customers • Decreasing the price of the products: - By using a systemic approach. - Standardise as much as possible to produce mass volume parts at low cost. Platform is at the core of the know-how of the carmaker. Designing sets of efficient platforms at an optimised cost provides those of carmakers which control technologies with very significant advantages versus competition. Many efforts are deployed to develop and engineer optimised platform The concept of platform varies from one carmaker to the other one. In all cases the platform is an ensemble composed of:  The underbody (which is the structure of the platform).  The systems that are attached to this underbody and that contribute to the mechanical properties of the car, as the suspensions and the powertrain. Considered systems are not the same from one carmaker to another January 27, 2014 2

  6. 6. Platform and underbody: process January 27, 2014 6
  7. 7. Platform and underbody: process January 27, 2014 7
  8. 8. Volkswagen Group Platforms January 27, 2014 8
  9. 9. Platforms to be build for a large number of vehicles Volkswagen Group: several brands – many vehicles in each brand January 27, 2014 9
  10. 10. VW Platform policy Production in Europe MQB (transversal engine) MLB (longitudinal l engine) January 27, 2014 10
  11. 11. From platforms by segment to broader concept 2005 : platforms by segment (in general one platform for each segment) vehicles which will be produced from MQB platform in 2017 MQB: Modularer QuerBaukasten – Modular Transverse Matrix (Construction Box) January 27, 2014 11
  12. 12. From platforms by segment to broader concept • 2017 : platforms over segments (same platform for different segments) – MQB example January 27, 2014 12
  13. 13. Standardisation to reduce cost January 27, 2014 13
  14. 14. Platform concept The design of a platform needs a systemic approach. The car must comply with a lot of constraints  Design • • • • Static (torsion, bending, acoustic) Dynamic (front, rear and side crash, small shock, pedestrian safety) Mass Roominess  Process • Installed tooling: flexibility  Minimum cost For cost reduction reasons, it is necessary to use a maximum of common parts over a wide range of models and derivatives. Generally, some basis systems of the car are designed, and then adapted to comply with the specification of a maximum of models. The attachment must also be standardised. January 27, 2014 14
  15. 15. Standardisation of general design January 27, 2014 15
  16. 16. Attachment points Underbody B Underbody A • January 27, 2014 Underbody C Important design approach • Standardisation of attachments of modules • Standardisation of parts • Assembly flexibility on a same line by using adequate pilot processes 16
  17. 17. Scaling Process Build models with different models on the basis of the same platform  Not multiply all the dimensions  But keep identical or similar the maximum of parts and keep identical the maximum of fixations (in particular holes used for assemblies)  Change the dimensions of a minimum of parts Use the same toolings  Stamping tooling to produce parts on demand Example: central floor  Welding and assembly lines January 27, 2014 17
  18. 18. Parts standardisation Underbody: around 100 parts from several grams to 10 kg (including around 30 parts> 1kg) January 27, 2014 18
  19. 19. Standardisation of position and attachments of modules January 27, 2014 20
  20. 20. Standardisation of tooling Flexible factory Up to 60 vehicles/hour January 27, 2014 21
  21. 21. Advantages and dangers of a modular construction January 27, 2014 22
  22. 22. Advantages and dangers of a modular approach Advantages  Reduce • Part cost • The cost of the tooling is spread over a larger number parts • Development cost  Decrease • Time to market for new vehicles and/or new versions  Focus R&D on • Less projects with more means Dangers  MQB platform can be by default over-designed and over-engineered for some basic segment models (A or B).  Cost of adapting the MQB base to specific projects. It may be more costly to adapt the MQB platform to a new project than to redesign a new platform  First investment and replacement cost of the toolings to adapt them to the new concept  Quality problems due a non-optimised design (due to the MQB platform constraints) January 27, 2014 23
