BMW M4 GTS Concept

Monterey/Munich – 08.14.2015 – A year on from the launch of the BMW M4 Coupe, BMW M Division is presenting an initial preview of a high-performance model for use on the road and, above all, on the race track: the BMW Concept M4 GTS.

The move sees BMW M Division once again returning to its roots. The BMW offshoot, founded in 1972 as BMW Motorsport GmbH, not only caused a sensation with its iconic BMW M1 racing car, but developed the first turbocharged engine to win the Formula One World Championship and was the force behind what remains the world’s most successful racing touring car – the Group A BMW M3.

And so the new BMW Concept M4 GTS continues the tradition of BMW M3 special models already illuminated by the BMW M3 Evolution (1988), BMW M3 Sport Evolution (1990), BMW M3 GT (1995), BMW M3 CSL (2003), BMW M3 GTS (2010) and BMW M3 CRT (2011). Technology honed in race competition, a hike in power, a commitment to lightweight design and limited production numbers have ensured these sharpest examples of their type offer unbeatable performance coupled with an emotionally powerful and exclusive driving experience.

“While the BMW M4 Coupe embodies the ideal combination of motor sport genes and unrestricted everyday usability, the BMW Concept M4 GTS previews an emotionally powerful and exclusive special model conceived with an eye for trailblazing technology and a keen focus on the race track,” explains Frank van Meel, President BMW M Division. “Despite its outstanding track ability, it is still fully road-legal. This is racing technology for the road in the truest sense.”

The BMW M4 GTS Concept showcases new technologies destined to make their series production debut in a new model to be unveiled at a later date. For example, the BMW Concept M4 GTS features the innovative water injection system that has already provided a significant output and torque boost in the BMW M4 MotoGP Safety Car. In addition, the BMW Concept M4 GTS has rear lights with OLED (organic light-emitting diode) technology that give the high-performance model a whole new look when darkness falls.

The world premiere of the BMW Concept M4 GTS takes place on 13 August 2015 surrounded by top-flight classic automobiles on display at the Monterey Car Week in California, USA.

Optimized down to the finest detail.
The BMW Concept M4 GTS builds on the BMW M4 Coupe’s dynamic and emotional use of forms. Yet its character as a high-performance special model, in which every detail has been developed to fulfill its purpose as a successful track machine, also comes immediately to the fore. The manually adjustable front splitter and rear wing – both in exposed carbon – ensure perfect aerodynamic balance and allow the BMW Concept M4 GTS to be adapted for both individual race tracks and for use on the road. Another example of the engineers’ rigorous adherence to lightweight design is the CFRP (carbon-fibre-reinforced plastic) bonnet, which lowers the car’s weight and centre of gravity further still. A wide front air intake optimizes airflow and minimizes front axle lift.

The dynamic and exclusive presence of the BMW Concept M4 GTS is accentuated by the exterior paint shade Frozen Dark Grey Metallic, with the Acid Orange accent on the front splitter creating an effective contrast. The lightweight, forged and polished light-alloy wheels in 666 M styling also feature an Acid Orange accent. The 9.5 J x 19 (front) and 10.5 J x 20 (rear) wheels are fitted with Michelin Sport Cup 2 tires (265/35 R19 at the front, 285/30 R20 at the rear). The mixed-size tires provide the ideal conduit for the stand-out dynamic attributes of the BMW Concept M4 GTS.

Water injection: power up, full-load fuel consumption down.
The engine powering the BMW Concept M4 GTS is equipped with the same innovative water injection system that has endowed the BMW M4 MotoGP Safety Car with a noticeable increase in output and torque.

The water injection system introduced by BMW M Division sees the engineers using the physical effect of water when vaporizing to draw the required energy from the ambient medium. The water is injected into the plenums of the intake manifold as a fine spray. When the water vaporizes, the intake air cools significantly. As a result, the final compression temperature in the combustion chamber – and therefore the engine’s tendency to “knock” – is reduced, enabling the turbocharged engine to use higher boost pressure and earlier injection timing.

This technology ensures an increase in output and torque, while at the same time reducing the thermal stress on performance-relevant components. All of which also enhances the stability and durability of the turbocharged engine. The BMW Concept M4 GTS therefore brings high-performance technology directly from the race track to the road.

The strong performance potential of the turbocharged six-cylinder in-line engine already demands an exceptionally sophisticated thermal management system for the engine and ancillary units. To ensure optimal operating temperatures in all situations, the M Division engineers have developed a highly innovative and effective cooling system. It comprises a main radiator plus additional radiators for the high- and low-temperature circuits, transmission and turbocharger in order to keep temperatures stable. The turbochargers are cooled by means of an indirect intercooler, assisted by an additional electric water pump.

OLED rear lights radiate ultra-high precision.
The BMW Concept M4 GTS is fitted with innovative rear lights featuring OLED technology. OLEDs (organic light-emitting diodes) are a new type of light source producing full-surface and homogenous illumination – in contrast to LEDs, which emit light to a single point. Their low installation height of just 1.4 millimeters and the ability to actuate individual light modules separately create fresh design scope in lighting concepts. OLED technology enables extra flexibility and forges an unmistakable appearance that signals exceptional precision.

OLED technology heralds a new era in light design and lighting concepts, and opens up new possibilities when it comes to a characteristic and distinctive light signature for BMW models – both for their daytime driving lights and during the hours of darkness.

BMW Team RLL survives to finish third as rain reigns in Watkins Glen – BMW leads GTLM class.

Munich (DE), 29th June 2015. Bill Auberlen (US) and Dirk Werner (DE) drove the number 25 BMW Z4 GTLM to a third place finish in a very wet “Six Hours of the Glen” on Sunday. The duo completed 157 laps of the 3.4-mile, 11-turn Watkins Glen International circuit (US) with the race slowed by eight caution periods and red flagged for 14 minutes during the worst downpour. The race ended behind the BMW M4 Safety Car during the last yellow flag with the GTLM victory going to the Porsche of Wolf Henzler (DE) and Bryan Sellers (US).

The BMW duo’s third podium finish of the season, including a win at Long Beach (US), moves Auberlen and Werner to the top of the GTLM driver points standings, and keeps BMW at the top of the GTLM manufacturer points standings.

The day ended in disappointment for the number 24 BMW Z4 GTLM of John Edwards (US) and Lucas Luhr (DE) as Edwards was caught out by the slick conditions on lap 77, spinning into the tyre wall entering the heading into the “boot” section and was retired from the race.

The race started with Auberlen in the number 25 BMW Z4 GTLM and Edwards in the number 24 car from the second and third class grid positions, which were decided on current championship positions after qualifying was cancelled due to heavy rain. Auberlen spun on the opening lap due to the rainy conditions and fell to the rear of the class. In the opening stint Edwards moved into the lead on lap 36 and Auberlen recovered to fourth. Both pitted ten laps later for Luhr and Werner to take over. Edwards was back in the umber 24 on lap 76, but went off on the next lap and the car was retired.

By mid-race the rain was in control of the race and with two hours to go the entire field was racing on wet tyres. As the conditions deteriorated the race was red flagged for 14 minutes with one-hour-and-28-minutes remaining. Auberlen was in the car for the final laps, and with 30 minutes to go he had moved into second place. He survived the difficult final minutes as the rain poured down causing the track to be extremely slick, affecting the car’s electronics and causing the engine to shut off intermittently. He lost second on lap 151 and was unable to get the position back as the race ended under a full course yellow.

Bobby Rahal (Team Principal, BMW Team RLL):

“It was a tough day and tough conditions. We had a little electrical glitch with the number 25 car, which caused us to lose second place right there at the end. The weather conditions made it difficult. It is a shame we lost the 24 car. All in all, another podium and the lead in both the manufacturers’ and drivers’ championship.”

Bill Auberlen (No. 25 BMW Z4 GTLM, 3rd place):

“That was a tough one. From the get go we were on pretty hard compound dries, and it sort of sprinkled and it looked like our car hated that combination – sprinkling and a medium tire we were out to lunch. Then the track would dry, you would come to the front, sprinkle and we would go back. On rains it was just the opposite. When we put the Michelin rains on I went right to the front. We beat everyone we needed to beat in the points and we are moving forward and that is all we wanted to do. I had an ignition issue with so much rain and my motor shut off coming out of the carousel, and that is how the Porsche got by me for second.”

Dirk Werner (No. 25 BMW Z4 GTLM, 3rd place):

“That was one of the most difficult races I have been in. It was a little bit like a Nürburgring feeling where the weather conditions really had a lot of surprises for us. We were out on a dry track and then out on slicks in the wet. Today everything was about staying in the race. Bill did a great job keeping the car on the road in the wet. I did my best and in the end I think we can all be happy with this podium. The car had a very good pace and it is very enjoyable to have a car like this BMW Z4 GTLM, which shows a good performance. So far we have had a very good season with quite a few podiums, and I have enjoyed it a lot so far.”

John Edwards (No. 24 BMW Z4 GTLM, DNF):

“It was a very disappointing end to a promising day. We were quick in the dry, and quick in the wet. I think the only conditions we struggled with were when we had some drizzle and were on slicks, but in most conditions we could go really fast. Regarding the incident, I don’t have much to say. The car snapped really quick and we checked the data quickly, but didn’t see anything obvious from the car side. I was facing the wall before I even knew anything was happening, so maybe there was the chance there were some weepers or something on the track, but whatever happened the end result was the same we are out of the race. We probably had the best car in the race and the best chance to win.”

Lucas Luhr (No. 24 BMW Z4 GTLM, DNF):

“To be honest it was a very disappointing day, just because I think we had a very strong car in both wet and dry conditions, and normally I think with a car like this you could win, but we didn’t even finish the race. This is very, very disappointing, not only for me personally as a driver, but I think also for the whole team and for BMW. If you get a chance like this in a championship that is so close you have got to take it. On the bright side, we know we have a very strong package, our BMW Z4 GTLM is mega, and really I have so much fun driving it. If you ask me now what I would do to make it better I cannot tell you, so that is a good thing. Our sister car at least got on the podium, but for the next race we need to get our heads together and take the opportunity which has been given to us.”

Four BMW M4 DTM cars finish in the points at the Norisring – Spengler is the best-placed BMW driver.

Norisring (DE), 27th June 2015. The fifth race of the 2015 DTM season, at the Norisring (DE), developed into a real rain and tyre lottery. Four BMW drivers scored valuable points today. It began to rain at the 2.3-kilometer street circuit shortly before the race was due to start, which led to differing tyre strategies throughout the grid. BMW Team MTEK’s Bruno Spengler (CA) was one of the drivers who started the race on slicks in his BMW Bank M4 DTM. After 46 laps, he was the most successful of the BMW drivers, finishing fifth. Victory went to Mercedes driver Pascal Wehrlein (DE).

Martin Tomczyk (DE, BMW M Performance Parts M4 DTM), the only BMW driver to begin the race on wets, took the checkered flag directly behind Spengler in sixth. DTM champion Marco Wittmann (DE, Ice-Watch BMW M4 DTM) finished his home event in ninth place, behind fellow BMW driver Augusto Farfus (BR, Shell BMW M4 DTM).

António Félix da Costa (PT, Red Bull BMW M4 DTM) and Timo Glock (DE, DEUTSCHE POST BMW M4 DTM) missed out on the points, as they finished twelfth and thirteenth. Tom Blomqvist (GB, BMW M4 DTM) and Maxime Martin (BE, SAMSUNG BMW M4 DTM) retired from the race.

Reactions to the fifth race of the 2015 DTM season.

Jens Marquardt (BMW Motorsport Director): “The weather lottery we were expecting is exactly what we got. We performed well and four of our cars finished in the top ten. By finishing fifth and sixth in unsettled conditions, Bruno Spengler and Martin Tomczyk were particularly impressive – although they both started the race on different tyres. Overall, our speed was okay on a drying track. We have improved since the opening races and can build on this. I wish to congratulate Mercedes who, once again, were victorious here at the Norisring.”

Bruno Spengler (BMW Team MTEK, 5th place): “Track conditions were difficult to work out today. As such, we needed to choose the correct tyre strategy before the race. My engineer selected slicks, which was precisely the right choice as I came through the field well. A big thank you to my team and well done to everyone – you all did a great job. I’m very satisfied with how my race panned out, but I do know that we have a lot of work ahead of us. I’m pleased we were able to score points today.”

Useful information:
The weather situation at the beginning of the race was so uncertain that some drivers chose wet tyres, while others opted for dry tyres. Martin Tomczyk was the only BMW driver to begin the race on wet tyres. The track had dried up so much about fifteen minutes into the race that all drivers had to change to slicks.
Maxime Martin was involved in a collision in turn one and had to withdraw from the race.

Due to contact with another car in turn one, Tom Blomqvist had to make an unscheduled pit stop. After twelve laps, he had to pit again and retire his BMW M4 DTM.

Fifth place was Bruno Spengler’s best result this season. The same is also true for Augusto Farfus, who finished eighth.

The second qualifying session begins at 11:40 on Sunday. Before that, the 15-minute warm-up is scheduled for 09:50.
