West Virginia researcher describes how Volkswagen got caught

The cheating scandal engulfing the world's largest automaker started with a road trip. In the spring of 2014, researchers from West Virginia were evaluating the tailpipe emissions of diesel cars made for the American market by European manufacturers, something never before studied in the academic realm. Excited by the prospect of breaking new ground, the team of two professors and two students wanted to gather as much data as possible. "And being academics, we went a little overboard," said Arvind Thiruvengadam, one of the students. "Being academics, we went a little overboard." Overboard included driving the cars for more miles than they needed to test and verify results. Drivers put about 1,500 miles on each of the first two cars in the study, a Volkswagen Jetta and BMW X5, along California roadways. For their final car, a Volkswagen Passat, they wanted even more mileage. So they took the car on a road trip from Los Angeles to Seattle and back again, collecting data from more than 2,000 miles of testing. The road trip was Volkswagen's undoing. When the West Virginia team returned to Los Angeles, they were befuddled by the test results. In theory, the Passat should have spewed the lowest levels of pollutants among the three cars. Equipped with the more modern selective catalytic reduction technology, the team expected to find minimal levels of nitrogen oxide. But the car, which had been certified at a California Air Resources Board facility prior to the start of the road trip, had elevated levels of NOx that were 20 times the baseline levels established beforehand. The researchers, comprised of professors Gregory Thompson and Dan Carder and students Marc Besch and Thiruvengadam, knew their on-board equipment functioned properly because, early in their research, they had double-checked its accuracy after recording sky-high NOx readings from the Jetta that showed 30 times the level of its baseline testing at the CARB facility. It was particularly noteworthy because the Jetta contained the first-generation Lean NOx Trap technology, not the more efficient SCR, yet both produced large discrepancies. The BMW, on the other hand, performed as expected. Today, Thiruvengadam is careful to say the research team never suspected Volkswagen of cheating on emissions testing, nor did the researchers report such a finding. They merely reported their findings to CARB officials who then further investigated.

Volkswagen poised to enter F1 with Red Bull

The Volkswagen Group could finally be preparing to enter Formula One, and enter it in a big way. That is, at least, if the latest reports prove accurate. And given the source, we're taking notice. The word around the paddock this weekend in Singapore has it that VW is entering into a partnership with Red Bull Racing that would see the German auto giant not only supply the team with engines, but buy the team altogether. The move would come as a welcome development for Red Bull, which took four consecutive world championships between 2010 and 2013, but has fallen off pace over the past couple of seasons due in large part to the under-performance of its Renault engines. The deal, which according to the report is currently being finalized, would see VW develop an all-new engine for Red Bull (and potentially for Toro Rosso and other customer teams), but the new power unit wouldn't be ready before 2018. In the interim, Red Bull would break off its current deal with Renault a year early and switch to another customer engine arrangement, with Ferrari currently rumored to be the favorite. The energy drink company that currently owns the team, in turn, would revert to a (prominent) sponsorship role - similar, it bears noting, to the role it plays with VW's World Rally Championship team. The termination of the relationship with Red Bull could spell the end of Renault's current F1 program, unless the French manufacturer carries through with plans to reacquire its stake in the Lotus team that was once its own. The VW deal would also ostensibly put to rest the mooted arrangement that would have seen Red Bull switch from Infiniti sponsorship and Renault engines to a similar deal with Aston Martin and Mercedes. What isn't clear at this moment is which brand Volkswagen would choose to promote with the new F1 program. Audi is speculated to be the favorite, which would likely spell the end of its Le Mans prototype endurance racing program – leaving that realm to Porsche after a solid decade and a half of dominance. The board in Stuttgart could, however, opt to hand the opportunity to one of its other brands, including Bugatti, Bentley, Lamborghini, Seat, Skoda, or the Volkswagen brand itself. The news comes from not only from the BBC, but from its analyst Eddie Jordan – a man who knows a thing or two about running an F1 team... and selling one. Jordan ran his eponymous grand prix team from 1991 through 2005.

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.
