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.

Recharge Wrap-up: BMW tests AdBlue pumps, Drivr is a Tesla taxi service

BMW is testing AdBlue pumps in Germany. AdBlue fluid is used to remove NOx from diesel exhaust, and it is stored in its own tank within the vehicle. Filling AdBlue is easy enough for drivers to do it themselves, and with the proliferation of diesel vehicles in Europe, a pump filling system could make more sense than using the current hand-held containers. BMW is testing AdBlue pumps at three fueling stations in Munich and Berlin to help develop further AdBlue dispenser technology. Read more at Green Car Congress. Drivr Green Personal Transportation is a Tesla taxi service in Cincinnati. Two former employees of Tesla Motors founded the startup, which bills itself alongside ride-hailing services like Uber and Lyft. Customers book a ride online, and are picked up by a Tesla Model S. The ride costs $2.50 per mile with a $15 minimum. Drivr currently operates three cars with seven drivers, with plans to lease another 10 Teslas and employ up to 30 drivers. The service will also be expanding to Denver soon, according to the website. Learn more at the Drivr website, or read more at Clean Technica. Ford is opening a research and development facility in Silicon Valley. The Ford Research & Innovation Center, which will be located less than three miles from Tesla Motors headquarters in Palo Alto, California, is expected to be one of the automotive industry's largest R&D facilities. "We're driving to be both a product and a mobility company, and ultimately to change the way the world moves," says Ford CEO Mark Fields. Read more at Automotive News. Law firms advising Fisker Automotive have been denied a $2.50-million fee enhancement in the car company's bankruptcy. Brown Rudnick LLP and Saul Ewing LLP were denied the extra fees, as a Delaware bankruptcy judge ruled there is "no evidence" that the firms provided anything more than what they originally expected. In denying the fee enhancement, the judge cited a "very high bar" for such awards. Read more at Law360.

Are you a BMW M4 GTS track car in disguise?

BMW is always happy to extract a little bit more gumption out of its M cars, just look at the latest 30th anniversary M5 or even the earlier CSL variants of the M3 for proof. Now, It looks like we might be getting the first glimpse of an even hotter M4, and it's wearing very interesting livery.
Our spies recently shot this M4 that could preview a future GTS version. It's all done up in MotoGP decals, but that might just be a ruse. This car sports a camouflaged lower air dam and rear wing, but those parts don't appear to be from an actual series safety car. The chin spoiler seems larger, and the rear wing is completely different. You can also spot an obvious Recaro logo on the driver's seat in one of the photos. Plus, the BMW emblem is removed at the back.
The disguised changes and odd choice of decals make this prototype incredibly weird. A BMW exec said at the beginning of the year that there were "no plans whatsoever to make a lighter, harder version just yet," of the M3 or M4, despite earlier rumors to the contrary. Check out the gallery to see what you think this is.
