The BMW 328 - lightweight construction as the principleBMW 328 is also a special BMW along the principle of lightweight construction is systematically applied to a BMW car for the first time. Wherever possible, the most mild and at the same time most powerful ingredients used, thereby keeping the total mass down to only 780 kilograms. In order to translate the idea of lightweight construction to this day and age, the main part of the exterior and interior BMW 328 Hommage made of carbon fiber reinforced plastic (CFRP). While in the old days they were more like aluminum and magnesium, CFRP is now considered to offer the best ratio between weight and stability. High-strength fiber fabrics are lighter than aluminum, but also more stable. Wherever this material has been used on 328 Hommage BMW, was also seen. In this way, the BMW 328 Hommage reflect not only functional lightweight construction principles, but also visual. BMW Group is leading the way in the production and use of CFRP in automotive construction and already has many years experience in the production of a series of CFRP roof and structural components for the BMW M6 and CFRP roof for the BMW M3.
Not only do the exterior and interior BMW 328 CFRP elements create an extraordinary statement. Up-to-date implementation of the character of the original vehicle was also expressed in the choice of other materials used on the inside and outside the vehicle. skin smooth, matt and high-gloss black and polished aluminum pestle and visualize the interior of CFRP in Hommage BMW 328 roadster pure and functional character of a sports car that day. Inside the vehicle there are also many details that come from motor racing, offer guidance on the most successful BMW 328 motor sport career. For example, pre-miere of vehicles in 1936 did not occur at the motor show, but on-track race. In the first race, the BMW 328 was opened to the public a higher-powered com-petition and dominate the entire European racetracks during the following years.
Dynamics and lightness in the interiorThe expressive exterior design of the BMW 328 Hommage depicts the modern interpretation of a highly emotional and dynamic two-seater Roadster - just like the BMW 328 75 years ago. "Hommage cars have a long tradition in the BMW Group. Based on our design philosophy "Rooted in history, moving for-ward in design", they demonstrate the significance of history for the present. Even 75 years ago, the BMW 328 stood for sportiness and agility through light-weight construction. The BMW 328 Hommage Car pays tribute to this past and shows how BMW lightweight construction will develop. Carbon is the material of the future." (Adrian van Hooydonk) In keeping with its role model, the BMW 328 Hommage has a streamlined design and is clearly recognisable as a sports car. Precise lines run across all of the car body's taut surfaces. As a result, a subtle contrast between the tense surfaces and the sharp edges is created within the flat, dynamic silhouette. The strong wedge shape accelerates the ve-hicle even when it is at a standstill, the scoops behind the seats take up the lines coming from the bonnet, guiding them dynamically into the rear end. The struc-ture of the CFRP mats gives the vehicle an appearance of depth, the diagonal lines of the woven CFRP additionally underscoring the dynamic design vocabu-lary of the roadster. Thanks to concise weaving, the carbon structure is clearly visible, optically emphasising the lightweight construction principle. Like the first BMW 328 test vehicles, with which the model celebrated its triumphant debut on the racetrack in 1938, then going on to gain a number of further successes, the BMW 328 Hommage has no doors. Then as now, deep recesses allow ac-cess to the inside of the car. The extremely wide and flat front end is strongly three-dimensional, generous surfaces and concise lines give the front end a powerful appearance. Viewed from the front, the CFRP bonnet appears to en-compass the vehicle from above. It embraces the vehicle, framing the slightly set back front end in a very distinctive downward sweep. Due to the almost vertical, low-reaching sidewalls, it simultaneously emphasises the BMW 328 Hommage's excellent stability on the road. As a result, the vehicle appears to be even flatter and more dynamic as a whole. Under the bonnet, further surfaces rise to embed the top and bottom of the distinctive kidney grille, whilst folding themselves around it to shape the adjacent air intakes. Openings and large air intakes create visual lightness at the front, simultaneously demonstrating the high air require-ment of the powerful three-litre, six-cylinder engine. Three-dimensionally de-signed lattices inside the front vents form a connection between the headlamps and the kidney grille, with the three-dimensional lattice structure acting as an accentuating feature.
Characteristic kidney shapeThe vertically positioned double kidney grille imitates the slim, vertical kidney design of the early BMW models. In those days, the BMW 328 was one of the first BMWs to feature it, after which it became further established with later BMW models. On the BMW 328 Hommage, the vertically mounted kidney grille is dynamically incorporated into the flat silhouette. It slants back roughly in the middle, thus blending in with the bonnet and the dynamic silhouette when viewed from the side. On the other hand, from the front it appears to be standing upright. The kidney grille bars are more prominently curved than the kidney grille surround itself. The vehicle displays the extremely round and appealing design of the original BMW 328 kidney grille when viewed from the side. The kidney grille surround is also distinctively three-dimensional, appearing to continue in-side the vehicle. Its front surface is finished in polished high-gloss, whilst the side surfaces have a matt finish. This detail gives the kidney grille a very high-class and up-to-date appearance. Behind the kidney grille bars, black horizontal fins obstruct the view into the engine compartment - just like on the 328 of 75 years ago.
Athletic rear endThe rear end takes on the design vocabulary featured on the front of the vehicle. Similar to the front end, sections of the sidewall form the framework for the de-sign elements that appear to protrude from the rear end. Between them, located far to the outside, are two clearly and concisely designed taillights sporting the characteristic BMW L shape. Two filigree luminous elements reflect a strongly curved interpretation of the typical BMW L shape, whilst a concisely constructed bar fitted to the outside of the lamp is directed vertically downward, separating the lamps towards the outside. The modern functional design of the taillights underlines the technical appeal of the vehicle.
The powerful sculpturing of the rear end also visually conveys the BMW 328 Hommage's lightness. Large vents and openings characterise the rear end, giv-ing it a light appearance. The distinctively horizontal section below the taillights forms a counterpoint to the intense sculpturing, emphasising the width of the vehicle. Below that, the rear of the car is strongly arched, a concise line partitions the surface, thereby providing an air of lightness. This large sculptural element adopts the form language of the front-end design surrounding the kidney grille. The wing-shaped element tapers both upward and downward, thus revealing two large latticed air outlets. The circular tailpipes are located inside these two openings. They protrude prominently out of the lattice and, combined with the distinctively designed wing shape of the lower air intake edges, underscore the power of the straight six-cylinder engine.
Details derived from motor racingThe interior design of the BMW 328 Hommage comprises a number of details that are reminiscent of the successful motor racing history of the BMW 328. For example, the slightly asymmetrically designed windscreen has a recess in the middle, similar to the windscreen design of earlier racing cars. Simultaneously, it marks the areas in which the driver and co-driver sit. Moreover, four wide leather straps run across the bonnet, which appear to dive under the side shoulder sur-faces to be continued on the side. This detail, which used to be considered an extremely sporty attribute, is also featured on the BMW 328 Hommage. Com-bined with the high-gloss aluminium safety buckles, the leather straps provide a touch of class in contrast to the very technical-looking carbon fibre. The modern quick-release fasteners for securing the bonnet bring racing of the past into the present. On the driver's scoop a large silver "75" as well as a small logo below it signify the reason for the BMW 328 Hommage. Next to it, the integrated tank filler neck protruding from the right-hand side is a striking detail. Whilst it pro-trudes prominently from the body of the BMW 328, the BMW 328 Hommage features a version that is integrated slightly more into the bodywork.
The large, prominently designed individual round headlights of the BMW 328 Hommage are reminiscent of the headlamps featured on the BMW 328, which were integrated into the wings for the first time. The three-dimensional interpretation of these round headlights is divided into four trans-parent, cylindrical elements, these being back-lit by LEDs. Between them, set-back black concave surfaces symbolise the typical tape cross used on headlights in motor racing. Around the four reflectors an illuminated ring emphasises the circular design of each individual headlamp.
The two-part light alloy wheels featured on the BMW 328 Hommage are a very special interpretation of the characteristic hole pattern of the original rims. The extremely concave high-gloss black aluminium rim boasts a contrasting silver-grey cover made of glass fibre. The insides of the angular milled holes have a high-gloss finish and are distinctively accentuated by a matt overlay. A black chrome butterfly nut bearing the BMW emblem completes the contemporary version of the wheel.
Clear and functional - the interior
The interior of the BMW 328 Hommage visualises the functional passion the BMW 328 exuded already back then. Thus the design of the interior is also pure and functional today. The entire interior structure is made of CFRP, conveying the lightweight construction concept of the BMW 328 into the inside of the car both visually and functionally. Due to the special application of materials, open-ings and freely suspended elements, the surfaces and different levels create an all-embracing feeling of lightness.
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.
The second layer begins next to the scoop, making a sweep towards the co-driver, then to float freely in front of him. This gesture creates a sporty but light sense of spaciousness, opening out a functional area in front of the co-driver. Between the driver and co-driver a multitude of recesses in the instrument panel and centre console create an airy and harmonious spatial experience, bringing the driver and the co-driver slightly closer to each other again in a sweeping ges-ture. The lines of the woven carbon fibres complement the interior design vo-cabulary perfectly.
Viewed from above, a slightly asymmetrical design of the bonnet and windscreen underscores the driver-orientated construction of the BMW 328 Hommage. The windscreen is larger within the driver's area, so the lines of the powerdome are of different length. Behind the windscreen they continue in the inside of the car, so that at this point both the interior and the exterior appear to be intertwined.
Authentic materials
Apart from CFRP, leather and aluminium, the interior deliberately features very few other materials. But every material that has been used is also visible. This provides the BMW 328 with a special authenticity. The contrast between the cool and technical-looking carbon fibre and the high-quality, warm brown of the leather characterises the interior. The exceptionally soft saddle tan leather has a fine grain and a slightly antique finish. On the seats the high-quality seam pattern enhances the appearance of the leather-covered seats even further. The seams in the centre of the sitting area of the seats and the silver-grey double-felled outer seams are a modern interpretation of the sports seats featured in earlier models, giving the seats additional character and depth. Aluminium is only sel-dom featured and, depending on where it is used, has a high-gloss or a matt satin finish.
Instruments and tripmaster
The instruments featured in the BMW 328 Hommage are both sporty and func-tional to an equal extent. The sparse instrument panel is dominated by the only round instrument - the prominently designed rev counter. Like the cockpit of the BMW 328 and typical of a sports car, the instrument cluster indicates in addition to engine speed only the oil temperature, oil pressure and water temperature. To the right of the rev counter, control lamps and a gearshift point indicator com-plete the instrument cluster. The instrument surrounds are finished in black chrome and made to the highest standards.
The puristic instrument cluster is complemented by the so-called tripmaster. The instrument panel of the BMW 328 Hommage is a fitted with two iPhones located in special holders and which assume additional display functions for the driver and co-driver. They are integrated into the self-supporting structure of the co-driver layer and, like the instrument cluster, are accommodated in a high-grade aluminium housing. The shape of the housing itself imitates the design of classic stopwatches, the two functions of the tripmaster being accessible through two further openings. Firstly, the iPhones function as stopwatches for measuring lap times and secondly as GPS roadbooks. Using two iPhones the driver and front-seat passenger/co-driver respectively can use both functions at the same time. After a journey, the iPhones can also be taken away in their hold-ers.
Apart from the instruments and the tripmaster, the BMW 328 Hommage is also fitted with further features taken from motor racing. In addition to being equipped with just the bare essentials in order to save weight, the BMW 328 Hommage is also fitted with modern 4-point seat belts, ergonomic seats and the "bone", a kind of emergency switch-off for the vehicle electronics, which is located between the two seats. The brushed aluminium belt retainers located next to the headrests ensure optimal guidance of the belts. These high-class, functional details are concealed behind the headrests, blending in harmo-niously with the overall concept.
