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.

2017 Audi A4 First Drive [w/video]

Internally, Audi refers to the A4 lineage with a B designation. Why the discrepancy? The model legacy traces back to the 1972 Audi 80, and the A4 name wasn't adopted until 1996 for the North American market. So the fifth-generation A4 is code-named B9. There is no confusion about what this car means to Audi. In 19 years, the brand has sold more than 12 million A4s around the world, which puts this new generation on the A-list when it comes to brand importance. If you squint, the new car looks like a facelifted version of the last-generation facelift unveiled in 2013. We get the same impression of the new A4 as we do with the third-generation Audi TT: it hasn't been comprehensively reconceived, it's been comprehensively re-detailed. But with a move to the updated VW group platform known as MLB Evo, 90 percent of the components on this car are new. On the outside, those changes are reflected through deeper sculpting on a body that's about the same height as before but 0.5-inches wider, one-inch longer, and with a wheelbase stretched 0.7 inches. The tweaked grille separates reworked Bi-Xenon headlights, which are standard across the lineup now – halogens go bye-bye. LED headlights are optional, as are the matrix units in other markets. Audi claims US-market cars will lose anywhere from 70 to 100 pounds depending on specification. Above those lights is a version of a clamshell hood – its shutline forms the front third of the pronounced shoulder line along the sedan's flanks. Audi designed a new hinge that keeps the hood lined up properly over the life of a car because small misalignments show more easily on the vertical seams. In back there are updated taillights, a standard rearview camera, and a trunk opening that's an even one meter across. In the press presentations, any conversation quickly turns to weight loss and aerodynamic efficiency. The only curb weight we have from Audi so far is for the base sedan, empty and without a driver, with the 1.4 TFSI engine that we don't get, coming in at 2,910 pounds. The current US-spec A4 is listed at 3,583 pounds, and Audi claims US-market cars will lose anywhere from 70 to 100 pounds depending on specification. About 35 pounds of that comes from the chassis, with new forged aluminum links on the suspension, fixed-caliper, four-piston brakes up front, and wheels that are never heavier than 26 pounds. The rest of the weight loss comes from the body, mostly through greater use of aluminum.

One Lap of America, with three times the madness

Instead of celebrating last weekend face down in a sombrero full of tequila-spiked OJ and a few lime wedges, 71 racing teams with one set of tires each and no support crews began Cinco De Mayo — and this year's 35th running of the One Lap of America — by hitting the wet skid pad at Tire Rack's headquarters in South Bend, Ind. There were Porsches, Vettes, Camaros and BMWs galore. There was a Miata, a vintage NSX, a Honda S2000 and even an old VW Rabbit. There were GTIs, the odd Evo and, oh yeah, six Toyotas, a couple of Vipers and a couple of GTRs. When the skidding stopped, a 2011 BMW 1M emerged triumphant and led the pack out into the heartland, where it will spend 5,000 miles this week hitting road courses, dragstrips and time trials at tracks as far west as Denver, as south as Fort Worth and then New Orleans. From there, it will barrel north through Mississippi, Alabama, Nashville, Kentucky and back home again to Tire Rack in Indiana. Twenty events, eight venues, with a three-hour window for each event. It's a nonstop, no-sleep, one-week road trip comprising 150-ish friends and brothers, partiers and pro racing drivers, spouses and other family-member combo packs. Some will never speak to each other again, some might end up divorced, some might get married. All of them are nuts. I know this because I made three laps. Three laps I will never forget.LAP ONE: 1984 Vehicle: 1984 Dodge Van Team #0: Jean Lindamood (Jennings), Walker Evans, Parnelli Jones I was present for the inaugural 1984 One Lap of America because I worked at Car and Driver back then and so did Brock Yates. He was the guy who came up with the clandestine, illegal, unsanctioned Cannonball Baker Sea-to-Shining-Sea Memorial Trophy Dash from Connecticut to Redondo Beach, Calif. It ran five times in the 1970s, with Yates joining Dan Gurney in a Ferrari Daytona for the second run. They won, Gurney insisting that "at no time did we exceed 175 miles per hour." One Lap was born of Cannonball nostalgia (read: Brock was bored), and I was beyond game for it. After securing a van from Dodge and two giant decals for the van sides, along with $5,000 in sponsorship from local Detroit Stroh's Brewery, I coaxed my friend, nine-time Baja 1000 winner Walker Evans, into running One Lap by suggesting he didn't have a hair on his ass if he refused. Then I suggested that if he didn't get his best friend and longtime road trip buddy, Parnelli Jones, to go with us, I would actually have to drive the van, too.
