BMW unveils 2016 X5 M and X6 M super CUVs

The second-generation BMW X5 M and X6 M have officially made their arrival for the speed-obsessed, crossover-loving masses that aren't willing to turn to Mercedes-AMG or Land Rover Special Operations.
While the new models retain their 4.4-liter, twin-turbocharged V8s, power has increased from 555 horsepower to 567 ponies. Torque is up more significantly, climbing from 500 pound-feet to 553 pound-feet. The extra twist is slightly less accessible, with peak grunt arriving between 2,200 and 5,000 rpm, rather than the earlier model's 1,500 to 5,650. Still, we'll take the ten percent increase in torque as a net win.
The big powertrain switch sees the old X5/6 M's six-speed automatic replaced with an eight-speed Steptronic transmission from BMW M. This new gearbox feeds power to an xDrive all-wheel-drive system that can variably shuffle up to 100 percent of power to either axle. In conjunction with the force-induced thumper under the hood, this powertrain arrangement allows both M models to hit 60 miles per hour in just four seconds. That's a mightily impressive stat in a 5,000-plus-pound vehicle.

All the crazy stuff we saw at McCall's Motorworks Revival

Every year, Gordon McCall puts on a lavish event packed with rare cars and planes (and the type of people that can afford rare cars and planes). And every year, more ridiculous stuff shows up. It's the good kind of machine overload. It's likely the only place in the world where you'll see a line of BMW 3.0s next to some Paganis next to a Porsche 911 by Singer Design next to a Ferrari salt racer next to a custom Olds Riviera next to the latest from Koenigsegg next to he coolest stuff Shelby ever made next to a hangar filled with McLarens, including a few P1 GTRs. And then all of that is surrounded by private jets, fighters, and planes that could have flown in directly from WWII. In a word, it's insane. Walk through the gallery above to get a taste for what was there this year for the event's 25th anniversary.

BMW reveals M4 safety car with innovating water injection system [w/video]

Racing series don't just pick their safety cars at random, or use just whatever car is lying around. These days the car that sets the pace at the front of the pack is typically provided through consideration by a sponsor. In the MotoGP series, that's BMW and its M division, which have served up the Official Car of MotoGP since 1999. What you're looking at is the latest, and it packs some innovative technology on board. Aside from the matte black wrap with BMW's iconic striped livery, upgraded aero kit, retrofitted interior and emergency equipment, this BMW M4 coupe packs a new injection system under the hood. Only instead of injecting fuel, it injects water into the combustion chamber – something that wouldn't usually be recommended, but BMW insists actually aids in the combustion process. The idea is that the temperature of the air being mixed with the fuel inside the engine is usually hotter than ideal, so the system injects a fine mist of water into the collector in order to reduce the air's temperature... sort of like one of those hydrating misters at an amusement park or outdoor mall, but in an even hotter environment. The system brings the temperature of the air down to a more optimal temperature, helping it combust better. The process is said to yield a number of positive effects. For one, it reduces knocking. For another, it can make more out of lower-octane fuel where higher octane isn't available. It also can control the adverse effects of higher ambient temperature on the combustion process. But most of all, it increases output and reduce fuel consumption by around eight percent. Whether that eight percent is worth the added weight of the system – particularly with water pump and a 1.3-gallon tank in the trunk – is up for debate. But we'd imagine that the Bavarian engineers have weighed very carefully. Of course there's also the matter of refilling the water tank, which BMW says would be carried out whenever the safety car is refueled, but in real-world conditions would only necessitate attention once every five top-ups at the gas station. By now you might have guessed that BMW probably didn't develop this system just for the MotoGP safety car, and isn't planning on keeping it confined to the racetrack. Instead it's being tested and demonstrated on the safety car before being rolled out on production models in the future.
