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.

Audi's lunar rover is nearly ready for the moon

Last year, Audi announced it was working on a lunar rover with a group called the Part-Time Scientists. Now the company says the design of its Lunar Quattro is complete, and all that's left is final testing before it's ready to head for the moon. Since Audi and its 16 engineers became involved with the project, the rover has actually increased in size, as have its tires. The company says this is for added stability. Despite the added size, the rover is now lighter, bringing it down from 38 to 30 kilograms (what we'd call 66 pounds). Otherwise, the rover is generally the same as it was last year. All four wheels are still powered by electricity, so Audi touts it as being both a Quattro and an E-tron vehicle. Cute. The rover will undergo final testing in the Middle East where it will run through simulations of the mission. For those unfamiliar, the mission parameters were set by Google for the Google Lunar XPRIZE. The prize is worth $30 million and will go to the first team to land a privately funded lander and rover on the moon, drive the rover 500 meters, and send back photos. If the mission is successful, we should get some great 3D and 360-degree shots of the lunar rover left behind by the Apollo 17 mission in 1972, since the proposed landing site is nearby. The Part-Time Scientists team that Audi partnered with has also booked a launch for its ALINA lunar lander, which will carry a pair of the Lunar Quattro rovers to the moon's surface. The launch was scheduled with Spaceflight Industries and is set for the end of 2017. Spaceflight Industries has managed 11 rocket launches with different companies and rockets between 2013 and 2015, and will also launch a probe from Israeli XPRIZE competitor SpaceIL sometime next year on a SpaceX Falcon 9 rocket.

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.
