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 recalls 2016 7 Series because airbags might not deploy

The Basics: BMW will recall 6,110 units of the 2016 7 Series, including versions of the 740 and 750 models with production dates from July 1, 2015, to December 11, 2015. The Problem: The luxury sedans have an airbag control module that could randomly reset because of an electrical short. If a driver has an accident while the system is resetting, then the airbags might not deploy. Injuries/Deaths: None reported. The Fix: Dealers will replace the air bag control module. If You Own One: The recall will begin on May 16. Related Video: RECALL Subject : Air Bags may not Deploy due to Residue on Module Report Receipt Date: MAR 25, 2016 NHTSA Campaign Number: 16V173000 Component(s): AIR BAGS Potential Number of Units Affected: 6,110 All Products Associated with this Recall Vehicle Make Model Model Year(s) BMW 740LI 2016 BMW 750LI 2016 BMW 750LXI 2016 Details Manufacturer: BMW of North America, LLC SUMMARY: BMW of North America, LLC (BMW) is recalling certain model year 2016 740Li, 750Li, and 750Lxi vehicles manufactured July 1, 2015, to December 11, 2015. The affected vehicles have an air bag control module that may randomly reset due to an electrical short circuit as a result of residual metallic particles from the manufacturing process. CONSEQUENCE: In the event of a crash while the air bag module is resetting, the air bags may not deploy, increasing the risk of occupant injury. REMEDY: BMW will notify owners, and dealers will replace the air bag control module, free of charge. The recall is expected to begin May 16, 2016. Owners may contact BMW customer service at 1-800-525-7417.

BMW i3 takes to the track, circles it in a way you don't expect

So, who wants to see a BMW i3 race around a track. That's what we thought. It's not a long video, but it is entertaining, and the way the urban EV does a 'loop' at second 25 certainly caught out eye. The i3 is scheduled to go on sale in the US later this year and will start at $41,350. The diminutive electric vehicle has a top speed of 93 miles per hour and can hit 62 mph in 7.2 seconds. We found it a hoot to drive, but we're not sure if hardcore BMW performance fans will totally 'get' this car's performance. The i3 is great at what it does, but it wasn't born to hit the race track. After seeing this video, though, we want a crack at it, skinny wheels and all. You can get a behind-the-scenes glimpse here, where Chris Neff writes, "The i3 basically turns in on itself. This is one sharp turning radius, take a look at 24 seconds into the video. We were actually trying to get the i3 to do doughnuts, but the computer would not let the rear brake loose, still, you can see how it held and how sharp we were turning....about 27 times in a row." Watch all 49 seconds below. And wonder with us if whatever aerial device was used to get the shot that ends at four seconds in was destroyed just after the video cuts away.
