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 02 Series mini-documentary makes us fall in love all over again

BMW's current reputation of building Ultimate Driving Machines can be traced back through history all the way to 1966, when the German automaker introduced the world to its 1600-2 two-door at the Geneva Motor Show. The car's name was simplified in 1971 to BMW 1602, and it went on to spawn the 2002, one of the most famous BMW models of all time.
BMW looks back on its past successes in a video that you can see below. As the automaker itself says in the video description, "This series was extraordinarily successful in reinterpreting the concept of the sports saloon and played a major role in motor sport long after production had come to an end." The 2002 would be replaced in 1975 by another legendary model from BMW: the 3 Series.
We'd be lying if we said we didn't long for something along the lines of the classic 2002 from BMW today. Since that doesn't seem likely to happen anytime soon, join us in remembering the cars that helped make BMW a household name by scrolling down below.

More details emerge on hotter BMW i8S coming next year

The BMW i8 recently won the Autoblog Technology of the Year award, and it's going to get even better. In October, Automobile magazine reported that BMW's i brand is working on an i8S that would be stiffer and more powerful, and celebrate the marque's centenary in 2016. At the time, one of two power unit combinations was suggested, either one of them good for more than 500 horsepower. Car magazine has added more info on the coupe said to be called Project M100, saying that in addition to being a birthday gift for BMW, it will also be a going-away statement to current chairman Norbert Reithofer, who is expected to retire in 2016 or 2017. It will also be so thoroughly reworked that there will be plenty of daylight between it and the standard i8: a more integrated carbon fiber and aluminum chassis, a wider range of materials used in the build, a larger luggage bay due to the omission of rear seats, a more aggressive suspension supporting heartier brakes and wider tires, and - perhaps - a different aero and ground-effects package to be visually different and make the most of the alterations. As for that power unit, Car says that the two options mentioned by Automobile are still under consideration, being either a 2.0-liter twin-turbo four-cylinder with 320 horsepower and a 204-hp electric motor, or a 3.0-liter straight six with 480 hp and an electric motor with 109 hp. Either choice gets an integrated starter motor good for another 27 hp, and a total torque number of roughly 520 pound-feet, 100 additional lb-ft than the current car. Word is that it will be shown for the centenary in 2016 then go on sale by the end of 2017.
