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.

2013 Dinan S3 BMW 550i

Steve Dinan has been enhancing BMW models since 1979. But don't throw his company into the ring with the dozen or so other tuners who tweak, tinker and piggyback upgrades on the famed German marque. Dinan is a tuner, but it's also an engineering firm that writes its own software, builds its own parts and then backs everything it does with a factory-grade warranty. That sort of fastidiousness comes at a price, but most of its customers - including the powerhouse of BMW Motorsport - rely on Dinan to help them come out on top.
In stock form, BMW's 550i is a formidable four-door with a twin-turbocharged 4.4-liter V8 rated at 400 horsepower and 450 pound-feet of torque. While those figures allow it to run with quick company (0-60 in 5.0 seconds, according to the automaker), Dinan puts the sedan's kettle on full boil with its S3 package. Starting with the engine, the performance engineering firm bolts on larger turbochargers, air-to-water intercoolers, a trick strut tower brace cold air intake, a quad-pipe free flow exhaust and its own engine management software. Pump in some premium fuel, and the result is 542 horsepower and 587 pound-feet of torque. Power is sent through the stock eight-speed automatic to a limited slip rear differential (Dinan will upgrade xDrive all-wheel drive models, too).
The Dinan S3 also features and extensive suspension upgrade that includes new front camber arms and low compliance rear control arms (engineered to reduce understeer and improve turn-in). The stock dampers are retained, but new bump stops are installed along with new springs. Overall, the car rides about a half-inch lower than stock to improve roll rate. To reduce unsprung weight, forged 20-inch HRE Performance wheels are fitted at all four corners (wearing Michelin Pilot Super Sport tires - 275/35ZR20 up front and 295/35ZR20 in the rear). Lastly, the company remaps the factory Electronic Damper Control (EDC) software with its own Dinan Shockware to work in conjunction with the new enhancements.

BMW details Concept X5 eDrive ahead of New York debut

Already weighing more than most other types of vehicles and with the space to accommodate the extra equipment, crossovers and SUVs arguably make for one of the more ideal platforms to transform into a hybrid. And there have been a handful of them - like the Audi Q5, Infiniti QX60/Nissan Pathfinder, Porsche Cayenne/Volkswagen Touareg, Lexus RX450h/Toyota Highlander and Cadillac Escalade/Chevy Tahoe/GMC Yukon - but by and large the majority of hybrids on the market are sedans and hatchbacks. BMW, however, looks poised to join the minority with the X5.
The Bavarian automaker showcased the X5 eDrive concept at Frankfurt last year, and as promised, has now revealed the followup it will present at the New York Auto Show in just a few days. The new Concept X5 eDrive, as BMW has now revealed, pairs a 2.0-liter turbo four good for 245 horsepower to a 95-hp electric motor to deliver a combined 340 horsepower. Its lithium-ion battery can power it for up to 20 miles and at speeds up to 75 miles per hour before the gasoline engine needs to kick in. All that without sacrificing the vehicle's utility, maintaining an almost perfectly flat loading floor with 40:20:40 split-folding rear seats, and without sacrificing much on performance, either: with a 0-62 time of seven seconds flat, the X5 eDrive concept is quicker off the line than the production X5 with the 2.5-liter turbodiesel and just a tenth off of the 3.0-liter turbodiesel.
With the full technical details now released (you can delve into it all in the press release below), the only question remains when BMW will actually put the X5 eDrive into production. Given its appearance in New York, though, we gather that whenever it does reach showrooms, it'll reach American ones as well.
