JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
In an area of conflict between tradition and modernity, the BMW Group is paying tribute to the BMW 328 on the occasion of its 75th anniversary with a special model – the BMW 328 Hommage. BMW showcased this model during the RetroMobile show in Paris.
The BMW 328 : lightweight construction as a principle
The BMW 328 was also a special BMW insofar as the lightweight construction principle was systematically implemented on a BMW automobile for the very first time. Wherever possible, the lightest and at the same time most robust materials were used, thereby keeping the gross vehicle weight down to just 780 kilograms. In order to translate the idea of lightweight construction into this day and age, major parts of the exterior and interior of the BMW 328 Hommage are made of carbon fibre reinforced plastic (CFRP). Whilst in the old days they favoured the materials aluminium and magnesium, CFRP is now considered to offer the best ratio between weight and stability. The high-strength fibre fabric is lighter than aluminium, but also more stable. Wherever the material has been used on the BMW 328 Hommage, it is also visible. In this way, the BMW 328 Hommage not only reflects the lightweight construction principle functionally, but also visually. The BMW Group leads the way in the production and use of CFRP in automotive construction and already possesses many years of experience in the series production of CFRP roofs and structural components for the BMW M6 as well as CFRP roofs for the BMW M3.
Not only do the exterior and interior CFRP elements of the BMW 328 make an exceptional statement. The up-to-date implementation of the original vehicle character is also expressed in the choice of other materials used on the inside and outside of the vehicle. Fine leather, matt and high-gloss black polished alu-minium as well as the CFRP interior visualise in the BMW 328 Hommage the pure and functional roadster character of the sports car of that day. Inside the vehicle there are also numerous details derived from motor racing, offering a hint of the BMW 328’s most successful motor sports career. For instance, the pre-miere of the vehicle in 1936 did not take place at a motor show, but on the race-track. In its first race, the BMW 328 declassified the entire higher-powered com-petition and dominated the racetracks of Europe during the years that followed.
Through the use of CFRP inside the BMW 328, the “layering” design principle, with which shapes take on clear functions, adopts a completely new form of ex-pression. Due to its exceptional characteristics, CFRP is in itself robust and can be shaped into self-supporting structures. Hence, only two large surface areas – so-called layers – define the interior of the BMW 328 Hommage. Both of them start at the bonnet and protrude into the interior. One of the layers extends to-wards the driver, reveals the entire driver’s workplace comprising steering wheel, control elements and scoop, thereby separating the driver and co-driver areas from each other. This spatial separation is indicated by a further material: the elegant, brown leather interior extends from the entrance across the driver’s area, over the seats to the scoop, thus becoming an integral part of the design vocabulary of the first layer. At the same time, the surrounding graphics compris-ing material and geometry create a link with the co-driver. On the driver’s scoop, a silver-coloured logo bearing the number 75 also gives indication inside the car of the festive occasion in honour of the BMW 328 Hommage.
