VW Golf 6

The best Golf ever

Bertrandt Wolfsburg helps to develop the sixth-generation Golf
With more than 27 million buyers, the Golf is not only a bestseller but also the market leader in the segment that bears its name: the Golf class. Since October 2008, the new Golf VI has been a common sight on roads throughout the world. The requirements that the new Golf has to meet can be briefly summed up: it has to be perfect in its class.

Development partner with complete vehicle know-how
The design department of the Wolfsburg office was responsible for the development and implementation of various requirements. Throughout this process, the Bertrandt teams from the Body-in-White, Doors and Closures, Exterior, Add-On Parts and Lighting and Vision Systems attained a high level of efficiency due to their close cooperation and interlinking of the individual development processes. Their proximity to the customer’s factory in Wolfsburg also enabled them to consistently respond to the customers’ requirements in the shortest possible time.

The rear bumper, rear lights, glazing and door modules were among the components designed by Bertrandt.

Partnership-based and interdisciplinary product development

Experts from the Body-in-White department were integrated into the team working on the new Golf VI. Above all, the Golf was given a more striking and sporty appearance due to the “tornado line” styling of the upper shoulder contour. These lines are supported by the headlights, the wings, the front and rear end and the rear lights that extend into the side section. A further task facing the Volkswagen special departments was the assembly of the side wall reinforcement frame as a carry-over part (COP) and its integration into the system platform.

Doors and Closures

Using a great deal of know-how and innovation, the door modules (2-door and 4-door models, closures, glazing) were designed as a complete development in the Doors and Closures team, from the initial design model right through to SOP. The result met the requirements regarding both design and engineering in equal measure. For the first time, the 2-door and 4-door models were developed in parallel rather than consecutively, as is usually the case.

Lighting and Vision Systems

Further support was provided by Bertrandt’s Lighting and Vision Systems team, which produced installation space models, cross-sections and drawings for the design of the rear lights. A further area of focus was the surfacing of the technical surfaces in the headlights (halogen and adaptive light system). In this case, Bertrandt was responsible for project management in the field of Surfacing and was in direct contact with the suppliers.

The Exterior team supported the development of components such as the bumpers, plastic assembly brackets, spoilers, headlamp cleaning systems and the M-Easy concept (self-adjusting front end). In addition to these components, the rear bumpers and the front bumpers with side markers for the North American region (NAR) were designed.

Add-On Parts

The Add-On Parts team also mastered the challenges presented by the project to the fullest satisfaction of the customer and delivered absolutely successful results. Among other things, the team took on the task of designing the wheel arch shells at the front (two-part) and rear as well as the rocker panel covers for the GTI.

Furthermore, the engineers took responsibility for developing the plastic under-ride protection for the engine plus the support bracket, the acoustic encapsulation with positioning of the resonators, the Cd floor panelling and air guidance components.

For the entire Golf VI project, all practice-relevant software tools were used in the product design process. These included the CAD systems CATIA V5, ICEM Surf and LucidShape.
