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 M4 vs. Lexus RC F in Head 2 Head sports coupe showdown

It's the showdown everyone's been looking forward to, the East versus West grudge match of the year. We're talking, of course, about the BMW M4 versus the Lexus RC F.
Although BMW uses a twin-turbo straight-six and the Lexus uses a free-breathing V8, the two are pretty closely matched on paper: a luxury coupe with over 400 horsepower channeled to the rear wheels.
The BMW has been doing these cars for longer, and the M4 boasts a higher power-to-weight ratio. But then the RC F has more power - and without forced induction to break up the rev range. So which is the better luxury muscle coupe? Watch the latest episode of Motor Trend Head 2 Head to find out.

Mini Vision Next 100 Concept: It's the autonomy, stupid

The concepts that Mini and Rolls-Royce showed off today – the Vision Next 100 Concept and 103EX, respectively – are all about autonomy. The Rolls-Royce doesn't even have a place for a "driver." And even though both are very much blue sky concepts, corporate parent BMW thinks it will make fully-autonomous cars within the next five years. That's according to Peter Schwarzenbauer, Member of the Board of Management of BMW AG, MINI, BMW Motorrad, Rolls-Royce, and Aftersales BMW Group, who also told us that both cars, at least in concept, are fully electric. The Rolls-Royce has dual-drive, 250kw motors mounted fore-and aft, on front and rear axles. While the Rolls is clearly a luxury concept for the monied few, the Mini is very much focused on a shared economy. Holger Hampf, Head of User Experience, BMW Group, said the chief design challenge of a car-sharing world is producing a car that could in theory mean different things to different borrowers. You get exclusivity because each car would morph according to the borrower's desires. BMW/Mini already have a car-sharing program in London called DriveNow, and a pilot program in Seattle called ReachNow, focused on the idea of shared exclusivity. ReachNow, which allows Mini/BMW owners to lend their cars out in an AirBnB-type scheme or to borrow "fleet-style cars," are immutable – however the car that was ordered is what the borrower or the owner will get. That's great if you're the owner, but it's also challenging for both anyone who'd buy that car used or for anyone borrowing the car. And if the future of most cars is a shared model (Ford is now offering multi-person leases among up to six buyers in a pilot program in Austin, Texas), customization is impossible. The result is what Schwarzenbauer derogatorily calls "normed." He says carmakers have to relearn to brand for a world where ownership is devalued but customization is key. To that end the MINI VISION NEXT 100 is "skinned." We've seen this before with the BMW NEXT concept that was revealed at the NY Auto Show this past spring, and the idea is to use the exterior of the car as a canvass that changes according to setting. Indeed Mini envisions that in a multi-driver household, the vehicle's customization could easily include changing colors according to driver preference – automatically. Dr.
