2016 BMW M4 GTS: More power, less weight, ready for the track

BMW calls its new M4 GTS the "most agile, radical, and powerful M4 ever." It's got 493 horsepower, a slick new water injection system, a three-way adjustable coilover suspension, and a weight reduction of roughly 200 pounds compared to a stock M4. Only 700 will be built, with 300 allocated for the United States. And did we mention it looks absolutely killer? Let's talk about that water injection system for a moment, because it's the first time this technology is being used on [an intercooled - Ed.] production road car. Basically, water absorbs heat from surrounding air, so a fine mist is sprayed into the intake manifold where it evaporates, lowering the temperature of the intake air. BMW says this reduces final compression temperature, allowing the turbochargers to operate with increased boost pressure and better spark timing. The end result is increased output – 493 horsepower and 442 pound-feet of torque from the same twin-turbo, 3.0-liter straight-six as the standard M4. That's an increase of 68 hp and 36 lb-ft. But the GTS isn't just about increased power. In fact, the bigger story is its weight reduction. BMW incorporated the use of aluminum and carbon fiber throughout the M4's construction, and DIN curb weight is listed as 3,329 pounds. It's unclear if that's the exact US measurement, and BMW couldn't comment on that as of this writing, but compared to our 3,530-pound stock M4, that represents some 200 fewer pounds of heft. Carbon fiber reinforced plastic (CFRP) is used in the hood, making that part some 25 percent lighter than the stock piece. CFRP is also used for the driveshaft, making it 40-percent lighter than the standard setup. Even inside the car, the new center console is 30-percent lighter than what you'd find in a normal M4. The rear seats are gone, and we're sorry to say that the cool racing buckets pictured here won't be available in the US. Making this thing super capable at the track is a three-way M coilover suspension, combined with upgraded carbon ceramic brakes, set behind staggered wheels and tires. Up front, the GTS rides on 19-inch rollers wrapped in 265/35-series Michelin Pilot Sport Cup 2 tires, and out back, 20-inch wheels are fitted inside 285/30-series rubber. The only transmission available is the seven-speed, M DCT dual-clutch unit, and when all is said in done, BMW says the M4 GTS will run the infamous Nurburgring Nordschleife in 7 minutes and 28 seconds. Another cool feature: organic LED technology.

BMW teases Airtouch gesture-based infotainment ahead of CES

At the last Consumer Electronics Show BMW revealed a gesture control system that employed a 3D sensor in the roof of a car to read hand movements made in front of the dashboard. That appearance in Las Vegas was a tease for the system we'd get in the brand new 7 Series. At next month's CES BMW will showcase a "Vision Car" with a concept interior of the future that incorporates the evolution of the current gesture system. It is called Airtouch. Permitting a wider variety of iDrive control, 3D sensors on the instrument panel read movements made with a flat hand so that driver or passenger can work their way through entertainment, navigation, and communication menus. Users can confirm actions with hand gestures, or with a button on the steering wheel or another in the passenger's door. We'll find out next month what the rest of the Vision Car includes. If this year's template is a guide, we'll also keep an eye on the coming 7 Series flagships to see if they include production versions of Airtouch. There's a press release below for more information.

At the Consumer Electronics Show (CES, 6 to 9 January 2016) in Las Vegas, the BMW Group is presenting a Vision Car to demonstrate what the interior and the user interface of the future might look like. The rapid advance of networking between driver, vehicle and environment is becoming increasingly intensive and is facilitating new services. One example of new technologies in seamlessly networked vehicles is provided by AirTouch. This feature empowers intuitive control of entertainment, navigation and communication functions using simple gestures made with a flat hand. AirTouch allows the display in a vehicle to be operated like a touchscreen without actually having to make contact with the surface. Sensors record the hand movements in the area between the central console and the interior mirror. This enables drivers or passengers to change the focus on the surface of the large panorama display. Simple confirmation selects the relevant menu item or activates an icon.Sensors on the instrument dashboard permit 3D control.One year ago, BMW already presented the new gesture control at the CES. This enables simple movements of a finger to carry out actions such as adjusting the loudness or accepting phone calls.

Researchers halfway to cutting carbon fiber costs by 90%

Carbon fiber has been utilized for decades to build racecars, as a means to cut weight while maintaining strength. But until recently, the space-age material has been largely absent from the street on anything but supercars because of the expense to use it. Recently, BMW signaled a major shift in that trend when it starting using carbon fiber reinforced plastic panels on the i3 and i8. This relatively small scale start might be just the beginning; the German company believes that a breakthrough to inexpensively manufacture the lightweight stuff is just on the horizon.
MAI Carbon Cluster Management GmbH counts BMW, Audi, Airbus, the German government and many other organizations as supporters, and it's researching how to make carbon fiber cheaper to produce, according to Automotive News Europe. The company thinks it can reduce costs by 90 percent in the near future. "We've certainly reached a halfway point on our cost-cutting target for suitable carbon-fiber parts," said project head Klaus Drechsler to Automotive News Europe.
Unfortunately, it isn't entirely clear just what MAI Carbon is doing to make such a huge leap possible. However, a recent post on the company's website talks about a new form a carbon fiber using a thermoplastic matrix that could be cured in less than three minutes. That's compared to about 90 minutes in the traditional process with an autoclave.
