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.

2015 BMW X6 M First Drive [w/video]

Please forgive my bluntness, and allow me to cut to the heart of the X6-dissenter argument right at the top. Yes, BMW will sell you a 2015 BMW X5 M that is the motive twin (I assume) of the X6 M you're here to read about, that is also cheaper, roomier, and more conventional in appearance. For many of you – especially the old guard that hears the descriptor "Sports Activity Coupe" and proceeds to unlock the gun cabinet – that's all you need to hear. Because, although the fickle community that consumes and comments on internet car culture seems to be fine with typical-looking SUVs and wagons packing performance-enhancing goodies, the idea of slanting the back of one turns them right off. And yet, BMW continues to sell the things; more than 250,000 units have be delivered in the X6 series' history. As if that weren't proof of concept enough, blood-rival Mercedes-Benz has unleashed the GLE, a coupe-like crossover of its own, complete with AMG pedigree. All of this brought me to Austin, TX, home of Hill Country, The Circuit of the Americas and the 2015 X6 M launch. On both road and track I found a car that was more powerful and blithely capable than ever, while also being exactly as weird to drive as it is a concept to comprehend. Given that the X5 M exists, and offers styling that is more like normal for the SUV genre, both the lovers and the haters of the X6 M are likely to be focused on the way it looks. Here, the 2015 model isn't very much changed from the original, meaning you aren't liable to change sides on the styling debate for this refresh. The '15 model has a slightly fewer black accents on the exterior, along with revised front and rear fasciae and vented (and chromed) front fender gills. The car is almost two inches longer than the existing model, but is near enough the same size in every other direction that you'd have to study the specification sheet to know different. Inside the X6 M that I tested was a beautiful, fully optioned cabin that boasted gripping sport seats and BMW's wide, easy-to-read infotainment screen. The leather-wrapped everything and carbon-fiber trim were both well executed, and my hands rejoiced at the feeling of the thick-rimmed, serious-looking steering wheel. Veterans of the current M5 or M6 will see a lot that looks familiar here, but to my eyes that's high praise. The most impactful changes aren't visual but visceral.

Project CARS vs reality at Laguna Seca shows amazing potential

Project CARS is aiming to be the next great racing sim. Offering a mix of modern and classic cars on famous tracks, developer Slightly Mad Studios is trying to inject a fresh energy into the genre, and at the moment its game looks ready to take on Forza and Gran Turismo.
The game is still about six months from release, and the graphics already look practically photorealistic. The video below shows side-by-side laps of Laguna Seca in a BMW - real life on the left and the game on the right. It's absolutely astounding. Other than some changes to the sponsorship around the track, they are almost identical.
Of course anyone with quality seat time in a racing sim knows that graphics are just one factor. How the game feels is even more important, and without getting hands on, it's impossible to judge yet. However, consider our interest piqued. Project CARS is scheduled to launch in November on the Sony PlayStation 4, Microsoft Xbox One, Nintendo WiiU, Windows PC and Steam OS.
