Researchers halfway to cutting carbon fiber costs by 90%

Carbon fiber has been utilized for decades to build racecars, as a means to cut weight while maintaining strength. But until recently, the space-age material has been largely absent from the street on anything but supercars because of the expense to use it. Recently, BMW signaled a major shift in that trend when it starting using carbon fiber reinforced plastic panels on the i3 and i8. This relatively small scale start might be just the beginning; the German company believes that a breakthrough to inexpensively manufacture the lightweight stuff is just on the horizon.
MAI Carbon Cluster Management GmbH counts BMW, Audi, Airbus, the German government and many other organizations as supporters, and it's researching how to make carbon fiber cheaper to produce, according to Automotive News Europe. The company thinks it can reduce costs by 90 percent in the near future. "We've certainly reached a halfway point on our cost-cutting target for suitable carbon-fiber parts," said project head Klaus Drechsler to Automotive News Europe.
Unfortunately, it isn't entirely clear just what MAI Carbon is doing to make such a huge leap possible. However, a recent post on the company's website talks about a new form a carbon fiber using a thermoplastic matrix that could be cured in less than three minutes. That's compared to about 90 minutes in the traditional process with an autoclave.

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 2 Series gets 3-cylinder Mini engine

BMW just keeps lopping off cylinders from its engines and sliding the ever-more-diminutive mills into its models. This spring, Europeans will get some of the automaker's smallest yet thanks to a new entry-level 2 Series that will share a powerplant with the Mini Cooper. The Bavarian company will also introduce a few other tweaks to the compact coupe across the pond. The 218i is the new 2 Series base model, and it shares its 1.5-liter turbocharged three-cylinder with the latest family of Minis. The engine makes the same 134 horsepower and 162 pound-feet of torque, but BMW does have some tiny changes for it. First, the orientation is swapped to fit lengthwise under the hood and drive the rear wheels. Just as importantly, buyers can order it with an eight-speed automatic, rather than the six-speed in the Minis. BMW claims that the little engine gives the 218i a 50:50 weight distribution, and it takes around 8.8 seconds to reach 62 miles per hour with the standard six-speed manual – tack on another tenth for the automatic. Either way, top speed is still a perfectly respectable 132 mph. Those acceleration numbers, incidentally, are over a second slower than what the latest Cooper is quoted at. Beyond this new base model, BMW will bring a few other additions to the 2 Series for Europe. The 220d oil burner will be available with xDrive all-wheel drive, and the company will introduce several new equipment bundles called Advantage, Luxury Line, Sport Line and M Sport. Each will bundle various options and trims together to appeal to buyers. No word yet on whether the 218i will eventually make it to North America, but we aren't holding our breath. Scroll down to read BMW's lengthy release about all of the changes set for the 2 Series. The BMW 2 Series Coupe: New entry-level engines, new model variants, even greater individuality. Premiere of the BMW 218i Coupe with 3-cylinder petrol engine from the new BMW Group engine portfolio and the BMW 220d xDrive Coupe – new and varied range of equipment features for model variants Advantage, Sport Line, Luxury Line and M Sport. Munich. From March 2015, new entry-level engines, a further four-wheel drive model and additional equipment options will increase the diversity of features available for the BMW 2 Series Coupe. With the market launch of the new BMW 218i Coupe, a three-cylinder petrol engine from the BMW Group's latest engine family will be featured for the first time in the brand's sporty and elegant compact model.
