German prosecutors investigating Audi for emissions scandal

After weeks of investigation into Volkswagen by prosecutors in Braunschweig, Germany, attorneys in Ingolstadt will also begin an examination into Audi's potential role in the emissions scandal. They reportedly received multiple criminal complaints that requested an inquiry, including one from Audi, according to Bloomberg. The prosecutors in Ingolstadt want to focus on people within the automaker that are responsible for emissions. However, the investigation is still too early in the process to identify any specific suspects. The German lawyers might also eventually combine their cases, but they remain separate for now. "Braunschweig took those parts that are clearly located at Volkswagen and asked us to keep the elements limited to Audi," a spokesperson for the Ingolstadt attorneys told Bloomberg. Audi has 2.1 million vehicles worldwide with Volkswagen Group's emissions-cheating four-cylinder diesel, including an estimated 13,000-14,000 of them in the US. The Environmental Protection Agency also recently filed a second violation notice against the 3.0-liter TDI V6 that was used in several of the company's models here, and the automaker responded with a stop sale for them. VW Group's carbon-dioxide emissions cheating in Europe also reportedly involves some Audi models. In that case, engineers admitted to artificially improving test results to achieve the cuts that the automaker requested.

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.

New safety and connected features help distinguish VW's lineup

Volkswagen may have wrested the title of world's largest carmaker away from Toyota this week, but the company still has some work to do in the United States. Despite its worldwide dominance, Volkswagen's American sales have languished. Unlike its red-hot Audi brand, mainstream Volkswagen sales have been afflicted by an assortment of maladies. An aging lineup, a reputation for mechanical gremlins and a lack of a competitive crossover vehicle have all hurt. In the US, the brand's cars claim only two percent of the overall market. As we reported earlier today, Volkswagen took steps this week to upgrade some broader aspects of its weaknesses here. At its Electronics Research Laboratory in Silicon Valley, the company announced it would make several advanced safety features and connectivity options available throughout the bulk of its lineup. Features that have long been available on its premium Audi cars will spread to its more economical offerings. In one big way, they will overstep their premium siblings. Volkswagen said Apple CarPlay, Android Auto (pictured below) and MirrorLink will all be available on a revamped infotainment system. Cars equipped with the new Car-Net-branded systems are arriving in showrooms now. Only last month, Hyundai became the first to offer CarPlay, debuting the smartphone-projection system in its 2015 Sonata. Chevy, Honda, and now Volkswagen, have quickly followed suit. On the safety-minded side, features like adaptive cruise control, forward collision warning, autonomous emergency braking, park steering assist and automatic post-collision braking will be optional equipment on most of the brand's 2016 model-year cars. Previously, the features had only been available on the Touareg SUV. They're now available on most Golf variants, the CC, Jetta, Sportwagen and some Beetles. Though the Passat sedan is one of the company's most competitive cars, it was curiously absent from the announcements, though an update could come later this year. While the advanced safety equipment is a boon for motorists increasingly interested in the technology, Volkswagen also added some basic safety tech that's long been available in mainstream competitors' cars, adding features like blind-spot monitoring and lane-departure warning. One of the big differences consumers might note is the cost of the driver-assistance systems.
