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 throws a Polo-palooza with four new or upgraded models

Volkswagen unveiled a parade of new and upgraded Polo models at the 2014 Geneva Motor Show, including the Polo TSI BlueMotion, Polo TDI BlueMotion, Polo BlueGT and CrossPolo (pictured above). While they will likely never make an appearance this side of the pond, it is fun to see what European subcompact drivers will be driving later this year.
The new BlueMotion models represent the most efficient petrol and diesel options in their class, according to VW. The BlueMotion TDI offers just 73 horsepower from its diesel engine but gives the equivalent of 76 miles per gallon (US) in the EU test. The BlueMotion TSI brings a little more power with its 88-hp petrol engine and has a combined rating of 57 mpg (US) in the EU cycle.
The Polo BlueGT provides a balance of performance and economy, and for the 2014 model, it gains a 9-horsepower boost to its 1.4-liter turbocharged to give drivers 147 hp at the press of the accelerator. This year's car also has an optional Sport Select suspension with electronically controlled dampers to improve handling a bit. It's still fitted with active cylinder management to use as little gas as possible when cruising.

Golf tees up new sales for VW

If you consider the Passat and the CC two different lines, Volkswagen USA lists nine different models on its website, and they have sold a total of 238,074 units in the US this year through the end of August. The Golf, which was voted North American car of the year in 2015, and its variants account for 44,416 sales, an increase of nearly 150 percent compared to the same period last year. That's also the most Golfs ever sold in that time in the US, and almost 19 percent of this year's entire brand sales. This is compared to a compact car segment that has gained just 1.1 percent compared to 2014. A number of factors are responsible, according to a report in Automotive News: the MQB platform allows different powertrains to roll down the same assembly line; VW USA product planners can now configure vehicles to suit our market and they work with a selection of dealers to refine the retail offering; and the Golf maintains its proper European driving experience. The expanse of the Golf range has meant not only increased profits and new buyers, but more breadth in the buying demographic - expanding outward from the standard Golf to five different extremes, from the e-Golf to the Golf R. Room will be made for a new kind of consumer next year when the current Sportwagen model goes all-wheel drive with an Alltrack designation. Unsurprisingly, VW USA says, "Golf is a role model for the US for us. We want to learn from our success and implement those lessons in our future model planning." After decades of uneven effort, perhaps that formula plus a long-awaited range of crossovers can finally deliver on the promise of the US market. Related Video:
