Audi-only rental car company expands

With the lines and occasional hassle, getting a rental car after a long flight can be daunting, even if you already have a reservation. Now, a company called Silvercar is trying to inject some luxury and modern, high-tech features into the process to make it less of a chore. The business recently expanded to O'Hare International Airport to offer visitors to Chicago a fleet exclusively comprised of silver Audi A4s. Silvercar is based in Austin, TX, and is being run by Luke Schneider, a former chief technology officer at ZipCar. He told Crain's Chicago Business that the rental industry "hasn't innovated in 30 to 40 years." Silvercar's big innovation is in the booking process. Like ordering practically anything today, it's all done through a smartphone app. Customers then scan a QR code on the Audi's windshield to get going. At the end of the rental, the bill is emailed to you. Prices start around $59 a day on weekends and $89 during the week, according to Crain's. Because they're all A4s with GPS and Wi-Fi, everyone gets the same car. In the world of ridesharing companies like Uber and Lyft, rental cars might seem passe, but according to Crain's, the rental market at O'Hare alone amounts to over $300 million a year. Silvercar's location there isn't at the actual airport, though. Instead, a shuttle picks up customers to take them to the company's site nearby. The business is working on a national rollout to 10 airports by the end of June, including major locations like LAX and Denver.

Audi kills off its 420-hp four-cylinder engine project

Audi's supercar-slapping, fire-breathing four-cylinder concept engine will remain just that, with Autoblog confirming that it has been internally killed off. Speaking at the launch of the TT RS, the engineering boss of Audi's Quattro GmbH division, Stephan Reil, said the Volkswagen Group had stopped all development of the 420-horsepower, 2.0-liter four it showed in the 2014 TT Quattro Sport Concept car (above). Despite previous assurances that Quattro had roles for both the EA888-based engine and Audi's wildly charismatic 2.5-liter, five-cylinder motor, post-Dieselgate reality has killed the smaller engine. "The 400-horsepower EA888 engine is dead," Reil said. The EA888 engine was conceived and developed by the same man behind AMG's powerhouse 2.0-liter four. Friedrich Eichler left AMG to become the Volkswagen Group's gasoline engine development go-to guy, and he was confident the 420-hp engine could be turned into a production car quickly, as was then-Audi development boss, Ulrich Hackenberg. It was even suggested that because the EA888 engine family bolted straight into the Volkswagen Group's ubiquitous MQB small-car architecture, the little powerhouse could be cheaply and quickly dropped into any of the company's cars that needed an image boost. Since then, Quattro has elevated the five-cylinder motor, switching it to an all-alloy block with a magnesium oil pan to cut down its weight while boosting its power and torque levels. Where the four-cylinder engine was shown with 420 hp and 332 lb-ft of torque, the production version of the TT RS's new five-cylinder engine totes 400 hp and 354 pound-feet of torque. The smaller engine's proponents claimed a 0-62 mph acceleration figure of just 3.7 seconds for the concept TT that carried it, and it might not be a coincidence that the all-new TT RS claims exactly the same figure. The 2.0-liter motor had a torque peak that arrived at 2,400 rpm and began to taper off at 6,300 rpm, while its power apexed at 6,700 rpm, thanks in part to a turbocharger that could feed it up to 1.8 bar of air. Flip to the TT RS' data and you're looking at more torque at lower revs and a touch less power, but at higher revs. That's not a lot of wriggle room for the concept engine to operate, especially when the perceived value of the five-cylinder engine is higher than the four, and the four's development and production costs would be higher than the five's.

Audi could buy back 25,000 older diesel Q7s

Audi will follow the example of Volkswagen here in the US, according to Germany's Der Spiegel. The paper reports that the luxury brand will buy back 25,000 vehicles with 3.0-liter, turbodiesel V6s that don't pass US emissions tests, and repair others. While we can expect an official update on the 3.0-liter TDI during a hearing on November 3, Der Spiegel's report could serve as a preview. The paper reports Audi will only offer owners of older Q7 TDIs buybacks. According to Reuters, Audi will repair an additional 85,000 vehicles that violate emission laws, although the report doesn't specify models. Audi USA's consumer information website lists an EPA "notice of violation" for all diesel-powered A6, A7, and A8 sedans, as well as Q5 crossovers, from model years 2014 through 2016. The Q7, meanwhile, stretches from to 2009 to 2016. We should also consider what Der Spiegel's report means for German consumers. Volkswagen has received a lot of heat across the pond over its decision to not offer buybacks in Europe, owing to the far greater number of affected vehicles. That both VW and Audi are looking at US buybacks is surely something that will irk the brands' critics in their homeland. We'll have more on Volkswagen/Audi's plans for the 3.0-liter TDI V6 on November 3. Related Video:
