Audi moves to patent electric Quattro and active-shutter wheels

Audi might have a few tricks up its sleeve for the coming years, with the Brits at Autocar uncovering a pair of patent filings made by the German luxury brand. The first is something we've seen before - wheel flaps - while the second is an evolution of one of Audi's trademark technologies.
We last saw wheel flaps on the Ford Atlas Concept in 2013, but the futuristic fuel-saving tech has so far failed to arrive on a production car. Audi may be seeking to change that, patenting the flaps that open and close automagically based on airflow. They can also open if the brakes get too hot.
The second patent is an evolution of Audi's Quattro all-wheel drive. The new AWD system uses an electrically driven rear axle and wheel sensors to figure out when and at which corner the car might lose traction, and is targeted largely at hybrid offerings, which is a field Audi has only recently dipped its toe into.

2019 Infiniti QX50 vs. compact luxury SUV rivals: How they compare

With apologies to the EX35, or whatever it was eventually renamed, Infiniti has been without a proper, competitive entry in the compact luxury SUV segment. You know, the segment that's growing faster in sales and entries than any other? To say the 2019 Infiniti QX50 is long awaited would therefore be an understatement. At first glance and drive, the new QX50 would indeed seem to be wildly more competitive than its predecessor, which come to think of it, was eventually called the QX50 as well. This one is based on an all-new front-wheel-drive platform, and although it lacks the inherent verve of the old, rear-drive- and 370Z-based one, the resulting increase in cabin space should be a welcome tradeoff. In fact, as you'll see below, the QX50 has gone from one of the smallest compact SUVs to the most spacious. How does it stack up in every other way? Say, against the segment's four best-selling entries last year: the 2018 Lexus NX 300, 2018 Acura RDX, 2018 Audi Q5 and 2018 BMW X3. On paper at least, really well as it turns out. Let's go to the spreadsheet! Discover and compare other luxury crossovers with our Car Finder and Compare tools. Comparing engines, drivetrains and transmissions With the exception of the Acura, all of the contenders come with 2.0-liter turbocharged four-cylinder engines. As you can see, the Infiniti is the heavyweight amongst the four-bangers, boasting the most horsepower and torque. The Acura V6 nips it by 11 hp, but the QX50 is still the overall torque champ. Plus, as we documented in the QX50 first drive, the Infiniti's new VC-Turbo engine is also the most technologically advanced. The Lexus is the wimp of the group and is also the second-heaviest, which isn't exactly the ideal scenario. The Infiniti is the only one in the group to feature a continuously variable transmission. That's not going to generate much applause around here. The BMW tops the gear count with eight, while the Audi is the only entry with a dual-clutch automated manual. The Acura and Lexus have only six gears, but they're good transmissions and it's not like their fuel economy is off the pace. The Audi and BMW come standard with all-wheel drive, while the others offer a choice of front- or all-wheel drive. Comparing cargo and interior space The new front-wheel-drive platform is paying dividends inside for the 2019 QX50, as it now boasts the most maximum cargo space at 65.1 cubic feet.

VW confirms development of 10-speed dual clutch, 134-hp/liter diesel

Each year, the Vienna International Motor Symposium showcases some of the up-and-coming technologies automakers are engineering for the use in passenger cars, and Volkswagen AG CEO Martin Winterkorn revealed some big developments VW is working on for its future products. Winterkorn discussed a multi-faceted approach that VW is looking to reduce its fleet fuel consumption and exhaust emissions.
Some of the bigger news he discussed included a "high-performance" diesel engine that will produce 134 horsepower per liter and a 10-speed DSG automatic transmission. While no specific applications were mentioned, we can only hope this is for the Audi R4 we keep hearing about.
Another topic he touched on that caused us to perk up our ears was had to do with VW's plug-in hybrid technology. While we know the PHEV versions of the Audi A3 and Porsche Panamera are on the way, Winterkorn also said that these two models will be followed up by Golf, Passat, Audi A6 and Porsche Cayenne plug-in models.
