Audi pushing DOT to allow its sequential LED turn signals [w/videos]

Still in the process of trying to get its trick LED Matrix Beam headlights legalized in the US, Audi is now trying to get its front and rear sequential LED turn signals approved by the National Highway Traffic Safety Administration. Just like its auto-dimming headlights, the sequentially illuminating turn signals don't meet NHTSA's Federal Motor Vehicle Safety Standard 108.
The problem, according to Automotive News, is that the individual lighting elements are too small to meet current US safety regulations. The rule states that each lamp should be 22 square centimeters (8.6 square inches) and the whole lighted combined area must be 50 square centimeters (19.6 square inches). In the individual sequence, Audi's lights are much smaller than that. As for the Ford Mustang, which has had sequential turn signals since 2010, this system is legal since the first lens is large enough to meet the required size, so the other two lights really aren't even necessary.
It sounds like it could be some time before we see these turn signals on Audis in the US, which is a shame because in addition to their styling bebefuts, we think they're more effective at signaling the vehicle's intended direction of travel, and they do a better job of grabbing the eye. Scroll down to watch a pair of videos showing the headlights in action on the redesigned A8/S8 as well as the recently updated R8.

2018 Buick Regal TourX vs. wagon competitors: How it compares on paper

To the great joy of auto enthusiasts nationwide, wagons are back! Well, at least there's a few more of them. The latest is the 2018 Buick Regal TourX, which we just had our first drive of and found to actually be quite good with pleasant handling, solid power and plenty of space. But, how does the TourX compare to other cladded wagons? Well, let's dive into the specs and fire up the ol' spreadsheet maker for Buick Regal TourX vs Subaru Outback vs Audi A4 Allroad vs VW Alltrack vs Volvo V60 Cross Country. True, some are from mainstream brands and others are from luxury marques, but Buick straddles both realms, so it's appropriate to look at them all. Of course, there's more to these cars than just the numbers, but they're still important, and in the case of this class of crossover-aping wagons, can vary more than you'd expect. So check out the specs in the chart below, which are followed by more analysis and photos of each. Discover and compare other wagons and crossovers with our Car Finder and Compare tools. Engines and Transmissions When comparing powertrains, the Buick is far-and-away the winner as far as torque is concerned, and is in a nearly three-way tie for horsepower. Its 295 pound-feet of torque is 22 lb-ft more twist than the next-most-grunty Audi A4 Allroad. And in regards to power, the Buick's 250-horsepower engine is only down 6 hp to the most-powerful Subaru and its optional naturally aspirated flat-six, and just 2 hp less than the Audi. At the bottom of the pack is the Subaru Outback with the standard naturally aspirated flat-four, which only makes 174 hp and 174 lb-ft of torque. That may not seem too bad compared with the VW Golf Alltrack, which only makes 170 hp and 199 lb-ft of torque, but the VW is much lighter by between 200 and 300 pounds. Transmission-wise, there's quite a bit of variation in the group. The Regal TourX and the Volvo V60 Cross Country rely on eight-speed automatics, all Outbacks use CVTs, and the Alltrack and Allroad have dual-clutch automated manual transmissions with six and seven gears, respectively. But for people that want to shift for themselves, the only option is the Volkswagen, which offers a traditional six-speed manual transmission on the Golf Alltrack. Cargo and Interior Space One of the main reasons to buy a wagon is for the body style's large cargo capacity. And for the most space for things and stuff, you'll want to check out the Subaru and the Buick.

Auto Express gets close-up look at the 2016 Audi R8

Audi invited Auto Express to the Ascari circuit in Spain to get a ride in the new R8 that will be introduced at the Geneva Motor Show. Jack Rix starts by giving us a walkaround of the camouflage-covered coupe, the obvious difference between it and the leaked image from a couple of weeks ago being the slatted front intakes. However, those intakes are present on the image Audi teased showing off one new, slimmer, laser headlight. The biggest shock: there will be no V8 model at launch - there will be one engine in two levels of tune. The first is the 5.2-liter R8 V10 with 540 horsepower, a bump of 15 hp over the present car. The second is the 5.2-liter R8 V10 Plus with 610 hp, a leap of 60 hp over the current model. That hotter trim, identified by its fixed rear wing, drops the 0-60 mile per hour time by a half-second to 3.2 seconds, and increases top speed seven miles per hour to 205 mph. Rix ran his fingers along the intakes behind the door and said he could feel sideblades, so all is not lost - what would an R8 be without sideblades? More obviously, on the V10 Plus Rix looked over there are new trapezoidal exhaust tips framing a serious diffuser in back. Underneath, the aluminum chassis adapted from the Lamborghini Huracan is 15 percent lighter than before and 40 percent stiffer. Shifting will be done via a seven-speed S-tronic dual-clutch transmission only. There are seven driving modes, a switchable exhaust note, and more direct variable steering. The German test driver Rix rode with said the new R8 is easier to drive faster, which - no matter what you think of the looks - will make it pretty special.
