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.

New BMW M3 and M4 Competition Package to cost $5500

Can't decide between a standard BMW M4 or the bonkers new GTS? The Bavarian automaker has split the difference with the launch of the new Competition Package available for the M3 sedan, M4 coupe, or M4 convertible. Under the hood, BMW M GmbH upped the output from the 3.0-liter twin-turbo inline-six from 425 horsepower to 444 – neatly bridging the gap to the 493-hp M4 GTS, and not limited to just the coupe. The power boost nets an improvement in the 0-60 time of 0.1 seconds, so if you apply it to an M3 sedan or M4 coupe with the 7-speed DCT, you'll be rocketing to 60 in just 3.8 seconds. At the other end of the spectrum, an M4 convertible with the comp pack and the manual gearbox takes 4.1 seconds for the same sprint. The M division also fitted an active suspension and diff, 20-inch forged alloys, and staggered tires. Vehicles fitted with the package can be visually distinguished by their black chrome tailpipes and glossy black trim. Fixed-roof examples also benefit from new seats, which the convertible has to forgo. So while it'll cost $5,500 to fit the Competition Package to a sedan or coupe, the cost for the convertible falls to a nice, round $5,000.

Woodcliff Lake, N.J.: January 13, 2016 6:00 pm EST...The BMW M3 Sedan, M4 Coupe and M4 Convertible are already regarded as the perfect combination of high-performance sports car engineering with unrestricted everyday utility. From spring 2016, all three body styles will be available with a special Competition Package from BMW M GmbH that combines added sporty personality with enhanced dynamics. As well as extensive handling upgrades, the Competition Package also comes with additional equipment features and a hike in power that takes output to 444 hp. The extra power means improved performance. The BMW M3 Sedan and M4 Coupe with optional 7-speed M Double Clutch Transmission (M-DCT) sprint from 0 to 60 mph in just 3.8 seconds (without Competition Package: 3.9 sec.), while the BMW M4 Convertible reaches the same speed in 4.1 seconds (without Competition Package: 4.2 sec). The sprint time for models with the standard 6-speed manual transmission is likewise 0.1 seconds faster in all cases than without the package.

Watch the trailer for Locke, a movie that takes place entirely in BMW's X5

It's no surprise that driving can be incredibly stressful. You're basically trapped in a metal box, and until fairly recently, your ability to communicate with the outside world beyond the toot of a horn or a rolled-down window was all but nonexistent. Locke, a new film starring actor Tom Hardy (best known for his role as Bane in the Batman movie Dark Knight Rises), capitalizes on that feeling of isolation and stress by setting the entire movie in a BMW X5.
Locke is written and directed by Steven Knight, author of Eastern Promises, and the trailer shows Hardy's character being put under increasingly intense emotional stress as he drives along in his Bimmer. We don't know much more than that, as the 90-second trailer really doesn't give away much.
The film premiered at last year's Venice Film Festival, and reviews are available that tell more about the story, but we don't believe in spoilers. It's poised to hit theaters in the UK on April 18 and the US on April 25. The trailer reminds us of a far more artistic take on Steven Spielberg's 1971 movie, Duel and has our interest piqued. Scroll down to watch the trailer, but consider yourself warned, there's a brief moment of profanity.
