The new BMW 8 Series Coupe undergoes vehicle dynamics testing on the racetrack

With the presentation of the BMW Concept 8 Series, BMW already offered a close-to-series glimpse at the design of their new luxury segment sports car. The dynamic qualities of the new BMW 8 Series Coupe are now also clearly manifesting themselves. A close-to-series prototype is currently undergoing intensive testing on a high-speed proving ground in Aprilia, Italy. The tests serve in particular to optimise the vehicle’s driving dynamics on surfaces with a high friction coefficient and mark yet a further decisive stage on the way to the launch of the new BMW 8 Coupe during 2018.

The test drives are being carried out with a heavily camouflaged prototype, which nevertheless gives strong indication of the new BMW 8 Series Coupe’s typical sports car proportions. As in the case of the BMW Concept 8 Series, the dynamically stretched lines, the flat silhouette and the powerful front and rear ends give a foretaste of the fascinatingly sporty driving experience.

This impression is confirmed with each lap completed on the proving ground in Italy. With its around 4 kilometres long oval circuit, including steep bends, the area situated in the proximity of Rome offers above all the perfect conditions for high-speed and high friction coefficient tests. Moreover, the acceleration, braking and steering behaviour of the new sports car are analysed on circuits, slalom courses and different road surfaces. The highly demanding test programme facilitates the targeted harmonisation of all drive and suspension systems. The new BMW 8 Series Coupe has shown that it offers maximum agility and precision in highly dynamics situations. Likewise, the car is also able to meet the highest demands in terms of supremacy and comfort.

“The test drives under the most severe conditions show that we are right on target with our concept for the new BMW 8 Series Coupe. The vehicle dynamics values already achieved are absolutely impressive. Our customers and fans can look forward to a genuine sports car,” says Klaus Fröhlich, member of the board of the BMW AG, Development and Research, who oversees the test programme in Italy.

The high vehicle dynamics potential results from an extraordinary close connection between motorsports and series production. The new BMW 8 Series Coupe is being developed parallel to and in close coordination with the BMW M8 and the BMW M8 GTE racing car. Whilst the prototype of the production model is undergoing endurance tests, the teams, which are supported by BMW Motorsport, are currently preparing in Daytona (USA) for the initial racetrack use of the BMW M8 GTE. On 27/28 January, the BMW M8 GTE will make its racing debut at the Daytona 24-hour race. In June 2018, it will then participate in the 24-hour race at Le Mans. The knowledge gained there and at numerous other racing events in the FIA WEC and the IMSA WeatherTech SportsCar Championship (IWSC) in North America will directly benefit series development of the BMW 8 Series Coupe.

Likewise, the know-how gained during training and on the racetrack will advance development of the new BMW M8. In June 2017, a prototype of this new model from the BMW M GmbH was already presented during the 24-hour race on the Nürburgring. The Nordschleife of the legendary racing circuit is also the main proving ground for testing and further enhancing the new BMW M8.

The BMW Group has defined its strong presence in the luxury segment as one of the major pillars of its NUMBER ONE > NEXT strategy. With the consistent extension of its model portfolio through the addition of the new BMW 8 Series Coupe and the new BMW M8, the BMW Group creates the ideal prerequisites for winning over the most demanding target groups and convincing them with a unique combination of supreme dynamics and modern luxury.

Innovative technology for a new legend: the new BMW M8 GTE

BMW Motorsport presented its new top-of-the-range model for the international GT racing scene at the International Motor Show (IAA) in Frankfurt am Main: the BMW M8 GTE. Before the BMW 8 Series Coupé goes on sale, the race car will compete on the track next season, including in the FIA World Endurance Championship (FIA WEC). It is with this series that BMW Motorsport will also make its return to the iconic 24 Hours of Le Mans (FRA). As such, the BMW M8 GTE will be associated with both innovative, cutting-edge technology and decades of motorsport tradition. At the IAA, the new car was on display in a BMW M Motorsport livery, designed especially for this occasion, providing a visual taste of things to come in 2018. It reflects the close relationship between the development of production vehicles and motorsport, and once again underlines the degree, to which BMW Motorsport and BMW M belong together.

The BMW M8 GTE enjoyed a successful roll-out on 1st July 2017 at BMW Group Plant Dingolfing (GER) – the very place where the production model of the new BMW 8 Series will be manufactured. The close link between production and motor racing is one of the cornerstones of the development of the BMW M8 GTE. The knowledge gained from race outings with the new car in the FIA WEC and the IMSA WeatherTech SportsCar Championship (IWSC) in North America will be directly incorporated in the development of the production model, which is running parallel to the motorsport project.

“The BMW M8 GTE is our new GT flagship and will go head to head with the strong opposition in this sector,” said BMW Motorsport Director Jens Marquardt. “For us, the presentation of the uncamouflaged car at the IAA is the next important step on the road to our first race outing, which we plan to be the 24 Hours of Daytona in 2018. The FIA WEC and the IMSA series in North America are a top competitive environment for our new challenger. With the BMW M8 GTE, we are bringing cutting-edge technology to the top international class of GT racing, whilst at the same time tying in with our tradition at Le Mans. The development of the BMW M8 GTE is on schedule, and we can hardly wait to see the car challenging for victories in 2018.”

Innovative technology for a new legend: the new BMW M8 GTE

A new degree of efficiency.
The V8 engine with BMW TwinPower Turbo Technology, which is restricted by regulations to a capacity of 4.0 litres, has a nominal base output of more than 500 hp, depending on the classification. The cylinder block and cylinder head are taken from the production engine and are produced in the light alloy foundry at the BMW Group plant in Landshut (GER). The focus of the development work is on achieving the greatest possible efficiency and maximum durability. The powerful production engine provides the perfect basis. The power transmission in the BMW M8 GTE takes place via a sequential, six-speed racing gearbox.

Artificial intelligence gives engineers greater freedom.
“Virtual development” plays a central role in the development of the BMW M8 GTE. For example, the traction control is being developed with the assistance of an artificial intelligence system. Topology optimisation with 3D printing gives the engineers far greater freedom in their search for innovative and creative solutions for the design of the car. Rapid prototyping also allows them to take delivery of a new part, as a usable prototype, just 24 hours after the virtual development.

Motor racing and production go hand in hand – design similarities.
Racing and production engineers closely worked together within the framework of the BMW M8 GTE project. For instance, consistent lightweight design also plays a crucial role in the development of the new GT sports car. A significant weight reduction is achieved through the extensive use of ultra-light CFRP components. At a length of 4,980 mm and a width of 2,046 mm, the car weighs just 1,220 kilograms. The design of the BMW M8 GTE also reflects the close relationship to the BMW 8 Series and the BMW M8. This is particularly apparent in the same roof line and the design of the front and rear lights.

Peak performance in aerodynamics development.
Work on the aerodynamics of a new race car is as time-consuming as it is indispensable. As such, it is all the more important for the BMW engineers to be able to work on the chassis of the BMW M8 GTE with maximum efficiency from the outset. A new algorithm allows a significant increase in CFD calculations, thus making it possible to use greater computing power to clearly increase the number of possible simulations, before progressing to the wind tunnel. Here, BMW Motorsport uses synergies with production development and benefits from the perfect test conditions in the BMW Group Aero Lab. One of the results of the aero development is innovative aero rims, which will be presented as a concept at the IAA.

Latest 3D measurement technology in use.
The close interdependence between production and motorsport development continues in another two important areas: the same 3D measurement technology that was used on the BMW M4 DTM, which made its first race outing in 2017, is also used on the BMW M8 GTE. The ultra-modern measurement system from the BMW production development department provides the perfect quality control once the race car has been assembled. With such a complex car as the BMW M8 GTE, which is built completely by hand, it is essential that all the dimensions are correctly adhered to and implemented.

Long history of BMW Motorsport in Le Mans.
BMW Motorsport returns to Le Mans with the FIA WEC in 2018. The last time a BMW race car featured on the grid was back in 2011, with the BMW M3 GT2. One year prior to that, the Jeff Koons’ (USA) BMW M3 GT2 Art Car had caught the eye, as it wrote the latest chapter in the story of the BMW Art Car Collection at Le Mans. Among the BMW Art Cars that had started previously at Le Mans were Alexander Calder’s (USA, 1975) BMW 3.0 CSL, the BMW 320i designed by Roy Lichtenstein (USA, 1977) and Andy Warhol’s (USA, 1979) BMW M1.

BMW Motorsport’s greatest sporting hour in Le Mans came in 1999, when Yannick Dalmas (FRA), Joachim Winkelhock (GER) and Pierluigi Martini (ITA) took overall victory in a BMW V12 LMR. The McLaren F1 GTR, powered by a BMW engine, had previously triumphed at the “Circuit de la Sarthe” in 1995.

The first time a BMW car started at the 24 Hours of Le Mans was back in 1939, when a BMW 328 claimed a class victory after 236 laps of racing. After 1972, BMW cars regularly lined up at the endurance classic.
