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.

EPA: Four 2014 Mini Cooper models need to drop mpg numbers

After the huge problems that Hyundai/Kia experienced with its mislabeled fuel economy labels, you'd think that any time an automaker has to adjust its mpg numbers, heralds would be shouting from the rooftops. But, after Ford admitted to three big mistakes with its numbers for the 2013 C-Max Hybrid and Mercedes-Benz had to lower the fuel economy rating for the C-Class, we understand if those heralds are a bit tired by now. The models affected include the 3-door and the 3-door S. Still, today's news is that BMW has to lower the fuel efficiency numbers for four versions of the 2014 Mini Cooper thanks to an audit conducted by the EPA and then some joint re-testing. The models affected include the 3-door with the 1.5-liter engine and the 3-door S with its 2.0-liter powerplant, with both manual and semi-automatic transmissions. As with the Benzes, the rating changes are not big ones, around one or two miles per gallon. The big exception is the manual S 3-door's highway number, which lost four mpg from 38 to 34. You can see all the numbers, new and old, in the press release below, but the EPA isn't saying what caused the problem this time. The Agency's new test procedures can't come fast enough. It should be noted that the 2015 Mini Cooper was recently delayed a bit because of the extra time it took to get the EPA numbers right. There's no confirmation that these two items are connected, but we would not be surprised to hear they were. EPA Requiring BMW to Correct Fuel Economy Labels for Four Mini Cooper Vehicles Washington - The U.S. Environmental Protection Agency (EPA) is revising estimates for four 2014 BMW Mini Cooper vehicles to ensure consumers are given accurate fuel economy values. The EPA performed a fuel economy audit on the BMW Mini Cooper and obtained values that differed from those BMW submitted to EPA for certification. With EPA oversight, BMW conducted new emissions and fuel economy testing, and EPA conducted its own testing at its National Vehicle and Fuel Emissions Laboratory in Ann Arbor, Michigan. As a result of this subsequent testing, EPA is requiring BMW to relabel four of its 2014 Mini Cooper models with lower fuel economy values. The specific changes to fuel economy stickers are listed in the table below.

BMW M4 pitted against i8 in drag race

Germany's Auto Bild has set up a very intriguing drag race to settle not just an inter-brand rivalry within BMW but a question of the old school versus the latest tech. The BMW M4 is a leader among the traditional sports coupes with a turbocharged inline-six spinning the rear wheels, but the M has to tackle the cutting-edge i8 with its turbocharged three-cylinder augmented with electric drive. See what happens when they go head to head. Even on paper, the race looks quite close. The i8 weighs about 300 pounds less than the M4 and also slightly nudges it out on net torque at 420 pound-feet versus 406 lb-ft. Also in some shots, the pavement looks just a little bit damp here, which would benefit the i8's all-wheel drive setup. However, the M-car has a healthy horsepower advantage with 425 hp against the hybrid's 357 hp. The race commences after a short introduction. Watch and see whether the traditional tech or latest layout wins the day.
