2017 Audi A4 Deep Dive

Unchanged. Plain. Boring. These words have been used to describe the new 2017 Audi A4, but they all miss the point entirely. Yes, the design of the new A4 is evolutionary, rather than a ground-up restyling. But as they say in ancient High German, "If it ain't broke, don't fix it." Of course, if you're at all interested in the 2017 Audi A4, you've probably read all about it in the official press release a few days ago. So we'll cut to the chase and tell you the bits you don't already know: the American-market details. We spent a day at Audi headquarters in Ingolstadt last week finding out the latest and poking around the A4 in the metal. The new A4 is wider, longer, and roomier than before. The lines are crisper and sharper, but yes, the proportions have remained very similar. That was done on purpose, thoughtfully. Not out of laziness. Stand any two sequential generations of Porsche 911 next to each other and you'll find they are rather similar. And yes, people do complain about that. But they also complain about the property tax rate on their third home in Monaco. That familiar-looking body gets a shockingly low coefficient of drag of just 0.23. The improvements in drag come from fine-tuning details down to the placement of the side mirror (now on the door, rather than the triangular window panel) and the contouring of the inner edge of the side mirror, which gets little vortex generating bumps to improve the turbulent airflow in that area, reducing drag. Attention to detail and refinement of a successful design – not boring, lazy repetition. Another notable departure in the styling of the new A4 is equally subtle, but even more significant from a precision manufacturing perspective: the hood has no cut lines on its upper surface. Instead, the hood now wraps around the tops of the fenders, the cut line integrating with the sharp crease that runs down the entire body side. The creation of this cut line requires extremely tight manufacturing tolerances to enable the precise alignment of the hood and fender gap with the stamped-in crease in the door panel; misalignment would be obvious and catastrophic to the clean, simple design's flow. Now, let's rip off this Band-Aid: no, we won't be getting the Avant. Why? Because no one buys it, vociferous vocalizations on the Internet aside.

Audi Prologue Concept [w/videos]

What you're looking at here is a preview of Audi's next-gen exterior and interior design. You can't tell, but in these photos, I'm wearing what can only be described as an ultra-white cloth spacesuit. Before opening the large driver's door of the Audi Prologue concept outside of the SLS Hotel in Beverly Hills, Audi requested that I don a super-attractive onesie so as to not let my flannel-covered human flesh touch the untreated leather surfaces of the Prologue's interior. I tied the spacesuit around me just above the waist, let my Converse poke out the footholes, and promised to hold in any sneezes. After all, I was being granted a serious privilege. I was about to drive the multi-million dollar, only-one-in-the-world Prologue that had just stunned crowds at the Los Angeles Auto Show days earlier. This isn't the first time Audi has bravely let the media sample its conceptual wares. In 2010, the German automaker granted us access to its incredibly enticing Quattro concept, probably hoping that the media would rave about the thing enough to convince the higher powers to actually green-light and build it. (We're still waiting on that one, of course.) You could argue that this same logic was applied when allowing me to drive the Prologue – it's no secret that Audi has been dreaming of a range-topping A9, though company officials told me that there is currently no decision on whether or not to produce such a car. But that's not really what the Prologue is about. As its name suggests, what you're looking at here is a preview of Audi's next-generation exterior and interior design, in a fully baked, fully functional package. Suit up, and behold the future. While the Prologue won't necessarily spawn its own production model, its elements will be incorporated on the next A6, A7 and A8. "Timeless but progressive." That's the key takeaway of the Prologue's aesthetic, according to exterior designer Parys Cybulski. The focus here is on beautiful, yet modern, simplicity. A design that looks both contemporary and forward-thinking at the same time, and something that will still look up-to-date in several years' time. After all, while the Prologue won't necessarily spawn its own production model, its elements will be incorporated on the next A6, A7 and A8. Up front, the most prominent feature is, of course, Audi's single-frame grille, seen here with a larger breadth than anything else in the brand's lineup, though its closest resemblance is seen on the new TT.

Recharge Wrap-up: Ferrock a carbon-negative cement substitute, Audi makes e-diesel

A cement alternative uses recycled materials and traps CO2 rather than producing it. Invented by David Stone at the University of Arizona, Ferrock uses recycled steel dust and glass to produce a substance stronger than conventional concrete. Cement has a high carbon footprint from the high heat needed to process the limestone. Ferrock needs no such heat, and it actually uses CO2 to harden, making it, as Stone calls it, a carbon-negative material.

Part of the Firmware 6.2 update, Valet Mode allows the owner to disable certain performance features and block personal information when letting someone else drive the car. It limits the car's to speed to 70 miles per hour, and caps output at 80 kW. It can also disable mobile app access, Homelink, Bluetooth and wifi and the "Places" function, which stores addresses for you. The folks at Teslarati did find some shortcomings in the new feature, though. Read more at Teslarati. Audi has produced its first batch of e-diesel made from water and CO2. The fuel is made by reacting hydrogen from the water with CO2 to make long-chain hydrocarbon compounds called "blue crude." That can then be refined similarly to crude oil to make e-diesel, which is a fuel free from sulfur and aromatic hydrocarbons. That e-diesel can be used on its own, or mixed with fossil fuel diesel to power a vehicle. "In developing Audi e-diesel we are promoting another fuel based on CO2 that will allow long-distance mobility with virtually no impact on the climate," says Audi Head of Sustainable Product Development Reiner Mangold.

Fuel of the future: Research facility in Dresden produces first batch of Audi e-diesel - The verdict: Pilot plant produces high-quality diesel fuel - No need for mineral oil: e-diesel made from water, CO2 and green power - Minister Wanka: "Synthetic diesel using CO2 is a huge success" Audi has taken another big step in the development of new, CO2 neutral fuels: A pilot plant in Dresden has started production of the synthetic fuel Audi e diesel. After a commissioning phase of just four months, the research facility in Dresden started producing its first batches of high-quality diesel fuel a few days ago. To demonstrate its suitability for everyday use, Federal Minister of Education and Research Prof.
