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.

Audi reveals facelifted A7 and S7 in Europe [w/videos]

Audi has revealed the nip/tuck and stylistic upgrades for the A7 that we got clues to in spy shots from back in January. The single-frame grille has been subtly reworked along with the lower front fascia and headlilghts. Those bulbs are underlined by a new design for the LED DRLs, and - in Europe - they can be had with Matrix Beam LEDs that come with dynamic turn signals. Out back is a tweaked bumper, as well as new exhaust tips and taillights with an LED pattern that mimics the front lights.
Cockpit inhabitants get new surface treatments like the aluminum and Beaufort walnut inlays, Valcona leather and five possible colors for the seats. The company's MMI Navigation Plus with MMI Touch is fitted with an Nvidia chip for faster graphics processing, and LTE-enabled internet connectivity is standard.
Up front, the 3.0-liter bi-turbo TDI gets a power boost to 320 horsepower and is attached to an eight-speed transmission; a seven-speed S tronic transmission is paired to the rest of the line. The revised 3.0-liter V6 TDI recently discussed at the Vienna Motor Symposium also joins the lineup, here offered in both the 272-hp and 218-hp variants, that latter "ultra" version said to return 50 US miles per gallon.

The 2018 Audi A5 and S5 Cabriolets are here just in time for winter

There are no big surprises with the 2018 A5 and S5 Cabriolet. As you'd expect, the convertibles share a design with their coupe counterparts, the A5 and S5 coupes, refreshed versions of which were unveiled earlier this year. Alongside the coupes and upcoming sportback models, the Cabriolets complete the A5 lineup. At least until another RS 5 comes along. In Europe, the A5 will have five available engine options, including three TDI engines maxing out at a 286-horsepower 3.0-liter, and two TFSI gas engines, with the most powerful putting out 252 hp. There will also be a choice of three transmissions including a six-speed manual, a seven-speed S-Tronic dual-clutch gearbox, and as an eight-speed automatic. For the US, though, the powertrains should be the same as the new coupe's, with a 2.0-liter turbocharged four-cylinder generating 252 hp and 273 lb-ft of torque in the A5, replacing the 220-hp turbo four in the previous model. An eight-speed automatic is a definite, although the existence of a manual A4 sedan for our market leaves some hope that a six-speed could be available in the A5 Cabriolet or at least the coupe. Audi also hasn't made final decisions on whether a front-drive model will be available here as it has been in the past. View 13 Photos The S5 Cabriolet, just like the two-door model, uses a new 3.0-liter turbocharged V6 engine that produces 354 hp and 369 lb-ft of torque, which is 21 more horsepower and 44 more pound-feet of torque than the old 3.0-liter supercharged V6 made. Despite the bump in power, the new S5 Cab hits 62 miles per hour in 5.1 seconds, just like the previous model. It is again electronically limited to 155 mph. And like the coupe, it will use an eight-speed automatic and get Quattro all-wheel drive standard. The A5 Cabriolet loses roughly 88 pounds compared to the previous model. The cars use an updated five-link front suspension and Audi claims the chassis is 40 percent stiffer than before. The soft tops have more insulation to cancel out road noise, take 15 seconds to open, and 18 seconds to close. You can do either at speeds up to 31 mph. The A5 Cabriolet will be available with Audi's latest array of driver assistance systems, including its navigation-linked adaptive cruise control and collision avoidance assist. A seven-inch display, seat belt microphones, Audi's Virtual Cockpit infotainment and gauge package, and a head-up display are available on the inside.
