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.

BMW spied testing new Alpina B7

Just last month BMW released the 2016 7 Series, ushering in a new era for the Bavarian automaker's flagship luxury sedan. And fans of big European performance sedans know what that means: Yes, a V12 model to follow, and maybe an M Performance variant at some point in the future. But before that, we're getting a new Alpina B7. Spied leaving BMW's test center at the Nurburgring, this camouflaged prototype for the new B7 appears to be wearing Alpina's signature low-key visual enhancements. Those include a subtle aero kit and upgraded rolling stock. Though we're only looking at it from the outside, you can expect the interior to feature some similarly discreet upgrades as well. The bigger question is what Alpina will have done to the new 7 underneath the bodywork. The outgoing B7 packed a 4.4-liter twin-turbo V8 with 540 horsepower and nearly as much torque, netting a 0-60 time quoted at 4.3 seconds and an autobahn-crunching top speed of 194 miles per hour. Hardly a slouch, then, but the new Alpina B7 is tipped to pack 600 horsepower or more, which ought to give the high-powered, high-speed, and high-end likes of the Mercedes-AMG S63, Audi S8, Maserati Quattroporte, and Jaguar XJR a run for their considerable money. We smell a battle heating up amidst all that burning rubber and sumptuous leather.

2016 BMW X5 M is big and bold, not beautiful

Awesome as it is, the BMW X5 M has never really been an attractive machine. Big and bulgy are the themes here, and that's only more pronounced with the X5's most recent refresh. But no matter, the X5 M has never been about looks - for this machine, it's all about performance, and BMW's hi-po crossover absolutely delivers in this regard.
Under the hood is the familiar 4.4-liter, twin-turbo V8, though power has been boosted to 567 horsepower and 553 pound-feet of torque - healthy increases of 12 and 53, respectively, compared to the outgoing model. Hitting 60 miles per hour is said to take just four seconds, which is damn impressive considering this thing weighs well over 5,000 pounds.
But the X5 M has always been shockingly good to drive, with limits you'll never reach except in the most hardcore track scenarios (which we'd really like to see, by the way). It's not the prettiest thing ever, but that's okay. It's not exactly cheap, though, with prices starting at $99,650. Woof.
