The following rendering is purely fictional and most likely won’t ever come to market, but it is interesting enough to publish under the “What If” series. Using a BMW M4 Coupe as the base car, the folks over at X-Tomi Design rendered on top of it a BMW M4 Shooting Brake. Shooting brake is a car body style that has evolved through several distinct meanings over its history and originated as an early 19th century British termfor a vehicle used to carry shooting parties with their equipment and game. The term brake was initially a chassis used to break in horses — and was subsequently used to describe a motorized vehicle. The term was later applied to custom-built wagons by high-end coachbuilders and subsequently became synonymous with station wagon or estate.

In contemporary usage, the term shooting brake has broadened to include a range of vehicles from five-door station wagons — to three-door models combining features of a wagon and a coupé. Some say, the shooting brake is essentially a two-door station wagon and that’s exactly what the rendering is showing here. READ ALSO: BMW 6 Series Shooting Brake Photoshop BMW currently offers the M4 in two variants – Coupe and Convertible – but a rumored M4 Gran Coupe has been highly discussed as well. Our sources say that, at least for this generation, no other variants are planned for the new M3 or M4, but the company is constantly evaluation the niche markets. For example, Mercedes-Benz is currently offering a CLS 63 AMG Shooting Brake and a CLA 45 AMG Shooting Brake, and other models are rumored to appear in the future. So we pose the question: which would you buy an M4 Shooting Brake? The article BMW M4 Shooting Brake – Rendering appeared first on BMW BLOG

BMW has partnered with Medium’s design hub, re:form, to explain how its design process works, and bring you an unrivaled insider’s look at the evolution of BMW’s iconic driving machines. When acoustic engineer Robert Berens advised the city of Boston on construction noise abatement in the late 1970s, jackhammers topped officials’ list of complaints. The bane of city peace and quiet, jackhammers blast out 110 decibels from two meters away, just slightly less than the crack of your average thunderclap. To Berens, the solution seemed simple: mufflers could be installed to reduce the machines’ noise. But it wasn’t quite so easy. “The DPW guys down to a man thought those [muffled] jackhammers didn’t work right,” recalls Berens, now a principal consultant at Acentech in Cambridge, Mass. They worked just fine, of course, but with the tooth-rattling noise reduced, the workers suspected the jackhammers’ power had been reduced, too. They’d lost the indicator they’d relied on to tell them everything was running as it should. For most people, sound is more than a set of vibrations; it carries complex social and cultural signals. This point has not been lost on designers, and thanks to new digital tools and the insights of big data, our soundscapes are being crafted with extreme precision. Engineers can manipulate the sounds our products and gadgets make so that they do more than please our ears — they influence our perception. Some of the most advanced uses of these techniques today are found in the high-end automotive industry, where engineers and designers now routinely lavish attention on every acoustic detail, from the sound of the engine to cabin noise to the squeak of the windshield wipers to the reassuring k-thunk of a car door closing — a subtle but remarkably influential sound when it comes to a potential customer’s decision to buy a new car, experts say. “The customer may not really know this is important for him, but this is something that really affects his decision to buy a car,” says Florian Frank, Specialist for Noise, Vibration and Harshness who works on acoustical design for BMW and is responsible for perfecting the sound profile of new car designs. “You can imagine that certain cars would have a sound that gives the customer the feeling of safety, of protection, of cocooning; other cars should give the customer the sensational quality of precision and control; and again other cars just want to say high value,” he adds.

For example, the new BMW 4 Series Gran Coupe is “a sporty car, so the door isn’t supposed to sound too heavy. It can’t sound too light, because a light door wouldn’t convey the right aspects of quality and safety. But it’s not supposed to sound too heavy, either. It should have a precise sound.” By contrast, “the BMW 7 Series would be a bit softer maybe, a bit darker in the sound as it’s our flagship sedan.” In Sound We Trust Click to hear the audio https://d1fcbxp97j4nb2.cloudfront.net/audio/1*YLEFRIo0jq8RasEb1_mJ-A.mp3 That’s the actual sound of a door closing on the new BWM 4 Series Gran Coupe. The moment the door connects with the frame, the metal parts of the latch collide creating a low but audible click. A thunk follows more clearly as the dampers and seals compress, decelerating the door nearly instantly as it locks in place, deadening the sound at once to create a crisp and precise effect. That’s not how it sounded when the first BMW 4 Series Gran Coupe prototype showed up for acoustic testing at the BMW design facility in Munich, Germany. Listen closely. Can you hear the difference? https://d1fcbxp97j4nb2.cloudfront.net/audio/1*QbUgWhTjqTg9tPoFJaBb5Q.mp3 In a battery of audiophile-quality recordings, BMW’s acoustic engineers did. They detected a slight imbalance between low and high frequencies, resulting in a “thin” or “light” sound. That was a problem, because consumers subconsciously tend to interpret imbalance as structural weakness, not protective strength. You can actually see the error in an audio fingerprint BMW made that visually captures the sound signature of the door.

This is an audio fingerprint of the sound of the door closing in an early prototype of the 4 Series Gran Coupe. The visualization shows a lack of proportion between the low and high frequencies, as indicated by the white rectangles. This pattern indicates a “thin” or “light” sound.

This is an audio fingerprint of the sound of the door closing in an early prototype of the 4 Series Gran Coupe. The visualization shows a lack of proportion between the low and high frequencies, as indicated by the white rectangles. This pattern indicates a “thin” or “light” sound. Notice the lack of symmetry between the heavy presence of red in the top left part of the graph, and the very thin streaks of turquoise in the bottom right. “Let me compare the whole thing with an orchestra,” says Alexander Ziemann, Head of BMW Aeroacoustics, Function Generated Acoustics and Watertightness. “When you want to design a sound you have to conduct a lot of instruments that play their role. And we have a lot of instruments in this orchestra starting from the latch over the hinges, some buffers, the metal panels, and all the door seals. “In the BMW 4 Series Gran Coupe, especially, we had a task, because more people are sitting in the back, and we have four doors without a frame around the window. So the big task was to make the system from outside and from inside sound good enough.” They began as usual, optimizing the dampening material on the side panels and some smaller things on the latch. When that didn’t work, they had to dig deeper. “It turned out the lack of an upper frame over the window created complications that were ultimately addressed by optimizing the dampening of the roof — it is very unusual to have to take that kind of step,” he added. The corrected audio fingerprint looks like this:

Note the top red and bottom green portions of the visualization indicated within the white rectangles are proportionally balanced In this case the red in the upper left is more evenly matched by the ratio of green in the lower right portion of the graph. Imbalance is one of a several common acoustical problems in door designs that engineers seek to find and eliminate. Others include the presence of “high-frequent impulses,” which sound like something has come loose inside the door.

The presence of this pattern indicates a hollow sound. IMAGE SOURCE: BMW Although most of this design work is done using computer simulations, acoustical engineers at BMW might get up to three prototypes to test on the way to the finished product. With these they might make up to 100 separate highly controlled recordings of a specific feature to isolate various sound qualities and repair imperfections. Equally important to the physical challenge of building a specific and well-defined sound is deciding what sound to make. BMW has been perfecting its acoustic engineering techniques for the past 15 years, understanding what effects various choices in panels and dampeners have on the final sound of the car. More recently, it has begun to do intensive market research with consumers to zero in on what sounds its customers consider most appealing. In one study, researchers interviewed over 800 subjects, collecting feedback on dozens of sounds, each one captured as a visual audio fingerprint and organized into a database with the various responses. Using this database, designers can customize different sounds for different classes of cars, and in the future, perhaps different markets. Such intense focus on sound design is rapidly expanding into new territory as our tools for predicting acoustical effects improves. Acentech in Cambridge, Mass. is just one of a growing number of acoustic design firms seeking to reimagine noisy products, from washing machines to vacuums, and for some the ambitions are reaching even further. Rudolph Stefanich, an industrial designer in Shanghai, earlier this year announced the Sono, a gadget that might one day allow us to customize indoor soundscapes by amplifying or dampening the noises that filter inside. As Megan Garber reported earlier this year in The Atlantic, with Sono you can ostensibly “amplify the songs of birds outside. And you can drown out the noise of the traffic on the street below.” Futuristic stuff, perhaps. Sono is still in the concept phase. But such leaps of imagination are not complete fantasies. They’re grounded in real world applications that have improved by orders of magnitude since the arrival of digital acoustic analysis techniques some three decades ago. “Before computers you used to take a Nagra recorder out in the field. Every reporter who ever did enthomusicology in Africa used one,” cracks Berens. “It was analog and we had sound level meters and analyzers and we could see spectrum. But with computers we could suddenly do digital analysis and an awful lot of math and figure out why things actually behave the way they do.” As we deepen our understanding of how people respond to sound, our newfound acoustic powers are quietly but profoundly altering our relationship to the worlds we inhabit, and create.

After rendering the BMW M4 Shooting Brake, the folks over at X-Tomi Design decided to use their Photoshop skills on the M6 Coupe. The result? A BMW M6 Shooting Brake rendering falling under the same “What If” category. As we mentioned in our previous article, shooting brake is essentially a two-door station wagon. In the premium segment, Mercedes-Benz is currently offering a CLS 63 AMG Shooting Brake and a CLA 45 AMG Shooting Brake, while Audi unveiled an Allroad Shooting Brake Concept at the 2014 Detroit Auto Show. Porsche has recently dropped the biggest hint yet that the second-generation Panamera will be offered in a Shooting Brake body style, as shown by the 2012 Sport Turismo concept.

Bmw M6 ShootingBrake2

BMW has yet to announce any plans to build a shooting brake model. Without a doubt, an M car with the proportions, elegance and dynamics of a shooting brake would be an instant fans’ darling, but the limited market and the fear of further dilution of the brand, would most likely impair any plans to build the car. If the M division were to build a shooting brake, then the BMW M6 Gran Coupe would be the best platform to start with and the car would give the Panamera a run for its money. Add a hybrid system to it with over 600 horsepower, and you have a winner in your hands. Should BMW build a shooting brake?

BMW was originally going to release the 1M as a limited production model of 2,700 units. Then due to overwhelming demand, the company lifted the cap and produced a total of 6309 cars until production ended in June 2012. To this date, it remains one of the most sought BMWs to own and also a rarity on the roads. With 740 units sold in the US and a further 220 sold in Canada, the 1M has become a collector’s item. From the factory, the 1M was released in only three colors: Valencia Orange, Alpine White and Sapphire Black. So when we came across a different paint job, we instantly stopped to look.

The BMW 1M Coupé uses a re-tuned version of the same engine found in a BMW 135i, which is used in various other models such as the 2011 BMW 335is coupe/convertible, 2011 BMW Z4 sDrive35is, and 2011 BMW 740i. In the 1M Coupe, the engine produces 340 PS (250 kW) at 5900 rpm and 332 lb-ft (450 Nm) torque from 1,500 to 4,500 rpm (with +369 lb-ft (500 N-m) overboost). The only available gearbox is a six-speed manual with a limited slip differential. BMW 1M sprints from 0-100km/h (0-62mph) in 4.8 seconds.

European Auto Source gets their hands again on an Alpine White BMW M4. The curvaceous performance car from the Bavarian car maker seems to be quite an interesting platform for future aftermarket projects. The attractive F82 M4 is offered at a starting price of $64,200 and comes with a dynamic exterior and stylish interior that commands attention, even when standing still. Add a bevy of aftermarket parts, and you have an incredible ride in your hands. When European Auto Source started this build, the idea was to further accentuate the performance and aesthetics of the M3, without impacting either in a significant manner. After arriving at the shop, the Alpine White F82 M4 received the BMW M Performance carbon fiber front splitters and lower splitter and a BMW M Performance carbon fiber trunk spoiler for starting the build properly.

With the KW HAS Adjustable Sleeve-Over Lowering Spring Kit the whole car was lowered, providing an aggressive stance, additionally accentuated by the Macht Schnell Competition Wheel Spacers that are sized 15mm in the front and 12mm in the rear. To put the finish on the project, Stormtrooper themed valve caps were added to the wheels. The BMW M4 is powered by a 3.0-liter BMW M TwinPower Turbo engine developing 425 horsepower. This engine combines two mono-scroll turbochargers with variable valve control (Double-VANOS and Valvetronic) and high-precision direct injection for a smooth and efficient power delivery, coupled with the standard 6-speed manual transmission. It’s a performance car, specially with the intelligent lightweight construction with Carbon Fiber Reinforced Plastic makes the M3 light, fast, and agile. Please take a look at the media gallery we’ve added below for more images of this project. Enjoy!
