2016 BMW M4 GTS hidden in plain view in Tokyo

We almost missed the 2016 BMW M4 GTS at the Tokyo Motor Show. As you can see in the photos, the car is sort of tucked into a little corner behind a wall, and it's way in the back of BMW's show stand. You'd never see it unless someone told you it's there. And that's a shame. This is one of the coolest cars BMW has launched in quite some time. Only 700 examples of the M4 GTS will be sold globally, with 300 earmarked for the United States. Aside from the aerodynamic and appearance upgrades, the GTS stands out by being the first production road-car to use a water injection system. We detailed this technology when the M4 GTS officially bowed, but the end result is more power. The GTS makes 493 horsepower and 442 pound-feet of torque – gains of 68 hp and 36 lb-ft over a stock M4. The other big news for the M4 GTS is its weight reduction – some 200 pounds have been removed, thanks to the use of carbon fiber-reinforced materials. The car's rear seats are gone, and several interior pieces have been redone in lighter materials, as well. This thing should be a monster out on the track, and we can't wait to get behind the wheel. But first, we're hoping BMW at least lets it out into the spotlight a little. See the car for yourself, live from Tokyo, in the gallery above. The new 2016 BMW M4 GTS an exclusive high-performance special edition M4 available for the first time in the US. - First production road car with a Water Injection System - World-exclusive OLED light technology - Specially designed full three-way adjustable M coilover suspension - Intelligent lightweight body design - Most agile, radical and powerful M4 ever Woodcliff Lake, N.J.: BMW today announced the new 2016 BMW M4 GTS giving BMW M GmbH a new and exclusive technological masterpiece which elevates the potential of the BMW M4 Coupe to an impressive new level. With its powerful, motorsport-inspired looks and high-performance technology, the BMW M4 GTS has its sights set squarely on the race track. Thanks to an innovative water injection system helping boost power to 493 bHP and track ready chassis, this Special Edition M vehicle recorded a lap time of 7 minutes 28 seconds around the legendary Nurburgring-Nordschleife, the world's most challenging race circuit, making a clear statement about this model's exceptional dynamic abilities. At the same time, the sharpest BMW M4 of all can also hold its own on public roads.

BMW dishes on 'lightweight' 2014 M4

BMW's M cars are not what we'd call featherweights. Sure, the big, bruising twin-turbocharged V8s deliver a lot of power, but the fact of the matter is that more weight often equates to less fun.
Which is why we're so excited over a recent sit-down the blokes at Top Gear had with BMW's product manager for small and medium cars, Matt Collins. The chat led to talk of the M3 Coupe replacing M4. Collins confirmed that, yes, the new M4 would be turbocharged. The new engine will also be a six-cylinder, which should make purists happy.
"What we'd like is more focus on lightweight engineering." -Matt Collins

BMW to offer carbon fiber wheels in a year or two

The Citroën SM sat on the first set of production glass fiber and resin wheels in 1972 when parent company Michelin developed the exotic hoops in order to take the SM rallying. It wasn't until 2008 that we got the first all-carbon-fiber wheel for passenger cars in the form of a prototype model from Weds Sports in Japan that remained a prototype. Australian company Carbon Revolution followed that a year later with its CR-9 all-CF wheel, first introduced on the Shelby Ultimate Aero and now available for independent purchase for about $15,000 per set. BMW could be the first OEM to offer entire wheels in carbon fiber reinforced plastic in two years.
The wheels - either all-CFRP or using a CFRP rim and alloy spokes - were shown off during BMW's Innovation Days in Munich and are products of the development work done on its i-branded cars. The full-CFRP wheel is 35-percent lighter than a forged alloy wheel, the hybrid alloy and CFRP wheel is 25-percent lighter, making for a decent drop in unsprung rotating weight. As demonstrators during a tech day the wheels aren't yet in the pipeline for production and EU approval, but an article in Auto Express claims that they could be on the market as soon as two years from now.
Other possible parts include a full carbon fiber steering wheel and propeller shaft, the latter of which is coming as a single-piece component on the new M3 and M4. BMW is also talking up its use of secondary carbon fiber - waste material from i3 and i8 production - that can be used for items like IP support structures, seat frames and spare wheels in place of traditional metals like aluminum and magnesium. There's an excerpt of the Innovation Day press release below with more details.
