2015 BMW X4

BMW has been in the line-blurring business of late, with the original X5 "Sports Activity Vehicle" muddling the line between SUVs and sport sedans in 1999, the 5 Series Gran Turismo challenging what our definition of "Gran Turismo" means in 2009, and pretty, low-roofed four-doors like the 6 Series Gran Coupe and the fresh new 4 Series Gran Coupe broadening the meaning of the word "coupe."
In the midst of all of this, BMW blurred the lines around both the SUV and coupe genres with its big, heavy, and in many ways ridiculous X5-based "Sports Activity Coupe" (cue collective eye-roll), dubbed X6. Auto wags scoffed at its lack of utility, compromised outward visibility and added cost, but a more emotional public was apparently smitten enough by its aggressive looks to avail itself of some 250,000 of them worldwide in six model years on sale.
Enter the all-new 2015 X4 crossover - err, "Sports Activity Coupe" - which BMW hopes will perform as well in the compact category as the X6 has on the next rung up the ladder. Like the X6, the X4 is a tough sell on paper: it's more expensive and less practical than the X3 on which it's based; it's heavier, despite the loss of interior space; and it doesn't even hold as much stuff in the back as the 3 Series wagon. As with the X6, the X4 is essentially a high-riding style statement that, like proper coupes (the two-door kind), says to the world, "You fools can take your need for practicality and shove it. I just want to look good."

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 GoPro integration now works with your iPhone

Coming this summer an upgrade to BMW's GoPro integration will combine the camera's feed with the M Laptimer app. This will let Bimmer drivers get a look at both lap telemetry and video replay at the same time. Despite the upgrades, BMW's setup lacks some of the features of the impressive Performance Data Recorder found on the Chevrolet Corvette and Camaro. BMW already let drivers control a GoPro through iDrive, but this improvement makes the functionality a lot more for track use. As soon as someone activates the M Laptimer app, the GoPro automatically starts recording. The video still saves in the camera's memory, but a low-res version also goes to the connected iPhone to sync with the app's data. Drivers can then see driving data on top of the phone's screen and the clip on the bottom (right). The M Laptimer monitors details like throttle input, speed, braking, steering angle, engine revs, fuel level, and g-force. Plus, the system records top speed, number of laps, best lap time, and the ambient temperature. We wish this system were as neatly integrated as the GM's Performance Data Recorder. For this system to work, a driver needs a GoPro HERO3 or later camera, the BMW M Laptimer app on their iPhone (4S or newer), a BMW model capable of running BMW Apps, and the phone must be connected to the infotainment system. Anything that can help shave a few tenths off a lap and then share the video of that accomplishment with buddies is a welcome improvement, though.

With this enhancement, when BMW drivers start and stop the BMW M Laptimer they simultaneously start and stop the recording of the connected GoPro camera. In addition to the video stored on the GoPro camera, a low-res version is saved on the phone so that it can be played back next to the map view on the BMW M Laptimer app. "The BMW M Laptimer and GoPro integrations have both proven to be incredibly popular with driving enthusiasts.
