LTE technology puts Audi in the driver's seat

The recently-launched Audi A3 Sportback was first-to-market with Long Term Evolution (LTE), or 4G, and LTE integration for connectivity on the move is an idea swirling all through the automotive world. Automakers see the faster speeds and faster responses of LTE compared to 3G as making it possible to one day have streaming video, cloud gaming, more intensive apps and even a virtual office with videoconferencing in your car. It will also enable more progress in machine-to-machine (M2M) adoption, giving cars a real-time ability to speak to one another and to infrastructure.
A video by Audi Deutschland looks at what might be possible not only for the average driver in an LTE-equipped car, but how a professional chauffeur might make the most of a car that can help him get his VIP passengers from carport to red carpet safely and on time. You can watch it below.

Next Audi RS4 to get an electric turbo?

We don't yet know if the next Audi RS4 will come to the US, but whoever gets it could find an electric turbocharger under the hood according to a report in Auto Express. The 4.2-liter V8 that has served for two RS4 generations is retiring from the line, replaced by a twin-turbocharged version of the supercharged 3.0-liter V6 used in the S4. But instead of using two sequential turbochargers - a smaller one to eliminate lag while a larger, more powerful turbo spools up - batteries charged by brake regeneration could power a first-stage electric turbo. The idea hasn't been publicly appointed for a particular model, as Audi's technical chief Ulrich Hackerberg has said that due to expense, that kind of setup "would only be used be used on the very top end models." Since the technology cuts down on the use of exhaust gases, it would also also help in markets like Europe where CO2 emissions are a factor. No matter whether it benefits from all conventional or some electric boost, the horsepower number for the twin-turbo V6 will be more than 420 hp but less than 503 hp, the rating of the V8-powered Mercedes-Benz C63 AMG. Auto Express believes Audi will want to maintain the power gap between the 333-hp S4 and previous, 444-hp RS4. With Hackenberg saying the new S4 will make more than 350 hp, that gets the coming RS4 up to at least 461, but AE figures it "could deliver as much as 480 hp." We'll find out sometime after the S4 launches next year.

The Audi R8 e-tron is dead with less than 100 built

According to a report from Car and Driver, the Audi R8 e-tron is dead (again!) after fewer than 100 examples of the all-electric model were built. This is an anticlimactic end to what could be termed an e-saga, with enough twists and turns to make a Hollywood scriptwriter sit up and start pecking out a screenplay. But here's the important number to keep in mind: 100. That's the production number the R8 e-tron failed to reach. The final tally is less than that, an Audi rep told Car and Driver. And what few were built were sold furtively, and only in Europe, in a strange back-channel in which dealers referred potential buyers right to Audi HQ, says the report. All of these transactions happened without the benefit of an online configurator or any published materials, we understand. That doesn't sound like a recipe for wild success – and neither did the $1,000,000+ pricetag. And this is just the latest stumbling block for the R8 e-tron, which was cancelled the first time back in 2012 when it was still based on the sinister, classic shape of the first-generation R8. If you recall, there was some confusion about the limited run of those first-generation cars, which were initially tipped to be sold to the public. In a strange move, Audi walked that back and held onto the cars for "internal purposes." So it was, until 2015, when we saw the second-generation R8 e-tron in Geneva. Audi promised it'd go on sale in 2015 "upon customer request," which was some foreshadowing to the unusual dealership referral sales model we discussed above. Nonetheless, it seemed like it would be a supremely interesting electric sportscar, with 456 horsepower, 679 pound-feet of torque, a 0-62 mph time of 3.9 seconds, and a range of up to 280 miles. Alas, except for the fewer than 100 European owners who managed to take delivery before Audi yanked the cord, the R8 e-tron's emissionless charms will go unappreciated. We're hoping to get more specific confirmation from Audi about the nature of the cancellation and the exact number produced; until then, stay tuned. Related Video:
