Renault Clio 4

From design through to volume production

The latest Clio sets new standards for style at Renault. It not only offers an impressive range of innovative equipment and features, but also meets the most recent safety and emissions standards. The Bertrandt Paris site was involved in the development of the new model from the initial design phase through to final production.

Bertrandt was commissioned by Renault to work on developing the saloon, estate and RS versions of the new Clio 4. The project began in 2009 and the Clio is now in production. Bertrandt provided Renault with a wide variety of design services. The wider wheel arches of the new Clio give it a more aggressive and sporty appearance. The use of more chrome trim and high-gloss paint creates a fresher, younger feel. In addition, it meets all the requirements for vehicle networking with its new multimedia console. The new city runabout is also slightly larger than its predecessor.

Bertrandt – Renault’s project Partner

Bertrandt’s French site made use of its entire spectrum of expertise from the design phase of the project to the start of volume production. In the early concept stage, Bertrandt designed a number of features and produced prototypes of chassis components. Furthermore, the members of the French team were able to make impressive use of their experience of starting up volume production. Specialists travelled to the Bursa plant in Turkey and the Flins plant in France to set up new processes. In addition to remaining within budget, Bertrandt also had to maintain Renault’s existing quality levels, which played an essential role in ensuring that the new model was competitive. By providing reliable solutions, our experts proved to be a driving force behind the improvement of the assembly processes. With its cross-disciplinary vehicle development skills, Bertrandt made a valuable contribution to the project and also designed vehicle geometry components. As a result of our long-term cooperation with Renault, we were fully aware of the client’s technical and financial needs, including working equipment, the requirements specification and adherence to schedules. It was also possible to achieve significant reductions in fuel consumption by introducing lightweight designs and improving the car’s aerodynamics.

More comfort, better features

The image of Renault cars has been enhanced both inside and outside. On the exterior of the car Bertrandt was responsible for designing the roof rails and the accompanying production tool. The other design services we provided included improving the windscreen wiper and washer functions and the horn. Another impressive new feature is the reversing camera which is incorporated into the Renault badge. The interior has also been completely redesigned. The arm rests have a more elegant shape and the fully foldable rear seats create a completely flat load deck, which can be enlarged even further by folding down the passenger seat. During the process of developing these features, the regulations concerning whiplash and clearances were carefully followed. Each new equipment range also comes in a wider range of colours. One striking new feature is the multimedia console with integral GPS and the touchscreen R-link system. In this area, Bertrandt was responsible for creating a harmonious design and coordinating the new components with the centre console.

The new Clio is available with four different engines, one of them a new diesel that meets the Euro 5 emission standard. Bertrandt was commissioned to design the engine installation space in accordance with Renault’s design regulations and the engine compartment architecture. During the design phase, the Bertrandt engineers ensured that the new design met vehicle safety and crash testing requirements. We were also involved in working on the chassis from the development phase onwards. In close collaboration with suppliers, our teams produced prototypes and carried out test rig and road tests. Bertrandt also took responsibility for the start-up of volume production at the Turkish plant in Bursa. Bertrandt employees from the Istanbul site provided on-site support when production began in Turkey. Logistics processes were set up for the chassis production and assembly line in accordance with Renault standards and training was provided for the employees.

Conclusion

Bertrandt once again demonstrated its reliability as an engineering service provider from the design phase to the start of volume production. We were pleased to be able to take part in the development of this new model and would like to thank Renault for the trust they placed in us and for their cooperation.
