What the Volkswagen I.D. concept tells us about the post-TDI future

If you've been paying attention, 2016 hasn't been a great year for Volkswagen. The TDI scandal removed VW's last crutch between our internal combustion present and the electric future, and so the company found itself scrambling to shift resources to show what's next right now. It's naive to assume that this is truly the sort of fairytale comeback story that VW's spin doctors would have us all believe, but it's notable that instead of flinching or pointing fingers, the engineers got to work. What they've produced is the I.D. concept, the third wave in VW's volume car history after the Beetle and Golf. The transaxle Golf was more than simply an updated Beetle, and likewise the I.D. is more than an electrified Golf. VW says the I.D. won't replace the Golf, but they said the same thing about that car replacing the Beetle. It's only a matter of time. VW says the I.D. won't replace the Golf, but they said the same thing about that car replacing the Beetle. It's only a matter of time. The I.D. approach is refreshingly simple: no carbon fiber chassis, no exotic battery chemistry, no outrageous concept car styling. The MEB chassis (the German acronym for modular electric platform) is made out of a traditional mix of high-strength steel grades to save costs and utilize existing factories. The battery is integral, not swappable, to reduce complexity and increase structural rigidity. It's also uses lithium-ion chemistry because of a proven track record and an existing (albeit deficient) supply chain. Contrast that with the e-Golf, which shares its chassis with the conventional internal-combustion cars. Fitting the battery and its ancillary systems became complicated and expensive. The skateboard installation in the I.D. will allow the pack to be optimized for the space available, reducing costs. As we've already reported, MEB will be shared across all VW Group brands to achieve an economy of scale, and the modular platform can be stretched to the size of roughly a Passat and down to a car slightly smaller than the I.D. It can be given all-wheel drive, although VW's e-mobility chief Christian Senger is quick to point out that the standard rear-drive configuration provides plenty of traction because of optimal weight distribution achieved with battery in the middle of the chassis. It makes all-wheel drive more of a bonus rather than a necessity in bad weather.

Stay in the house from the Audi R8 Emmy ad

Audi is sponsoring the Emmys again, and launching an ad alongside the awards show that features a family living in the middle of the desert simply to have an excuse to drive their R8s as much, and as fast, as possible. Which is crazy. Even crazier, you can live in the exact house from the ad for a few days as part of an airbnb promotion. The stay includes chauffeured transportation from Las Vegas McCarran airport, all meals prepared by a personal chef, and an R8 V10 Plus in the driveway available for driving. Did we mention it's a real house and not just an advertising prop? It is. The 1,200 square foot Rondolino Residence sits on 80 acres near Scotty's Junction, Nevada, just over 2 hours northwest of Las Vegas. Beginning September 18, seven three-night stays in October will become available - one booking opens up each day at 9 PM Eastern. The rate is listed at $610 per night, with the bookings running October 10th through November 1st. You can book the experience, or try, on the airbnb page. As for the ad, titled "Desolation," at first it seems like a entertaining jaunt about the lengths people will go to for an amazing driving experience. A deeper (and totally unreasonable - it's just an ad) analysis suggests some truly troubling things going on. For starters, the lackadaisical parents let the children taunt a poisonous scorpion. Will the isolated upbringing and history of cruelty towards animals produce a future serial killer? In our deranged version of this fictional universe, yes. Second, the R8 - spoiler alert, both R8s - get super dirty on the run to the corner store. A corner store, which, seemingly unequipped for coffee roasting nevertheless has fresh artisanal beans sold in half-pound bags. Lacking a bulk purchase option, the plot of the ad surely repeats itself several times a week. That sounds insane, but hey, it's all about the drive. And we do love the "Leadfoot Coffee" easter egg. But we digress. Where is the car wash that left the R8 clean before the drive through the desert? And where is the second R8 parked? The male protagonist clearly drives out of the garage from a position that doesn't leave room for the second car. We can only surmise that there is a underground component to the house in the ad. To be clear, we're still in fictional universe of this ad - the real Rondolino Residence, like the Alamo, lacks a basement.

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.

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.
