Audi RS3 and Volkswagen Golf R face off in Evo test

Typically when an automotive publication pits two rivals against each other, they come from different companies. After all, why would one automaker – even one parent company – develop two distinct models to compete against each other? Well, the Volkswagen Group isn't like most. It pits Porsches against Lamborghinis, Audis against Bentleys, Seats against Skodas... all under the same roof. In the high-powered hot hatch market, it offers both the VW Golf R and the Audi RS3. The question is, which is the better drive? Evo put them both on track for a quick bout of sibling rivalry to find out. On paper it would seem like an unfair fight. Sure, both are based on the same platform and channel their power to the tarmac through all four wheels. But the Audi's five-cylinder engine packs considerably more muscle than the Golf's four: 362 horsepower and 343 pound-feet of torque trump 296 hp and 280 lb-ft. There's just no way around that – at least until the Golf R 400 comes along. The Audi, as you might have guessed, also costs substantially more than the Volkswagen. But that's not Evo's concern here. This is a cost-no-object, bare-knuckle throw-down. Watch the ten-minute video above to find out if the cheaper, less powerful Golf R can keep pace with its more upscale and brawnier brother.

VW quite interested in solid-state batteries for EVs

Volkswagen is about to make a decision about which advanced battery technology the automaker will seriously investigate to give its electric vehicles more range. VW will decide by July if it will use solid-state batteries made by US-based QuantumScape Corp. in future EVs, according to Bloomberg News. Last year, VW bought a five-percent stake in QuantumScape, which was founded by ex-Stanford University researchers. The lure is that QuantumScape's solid-state batteries may provide a single-charge range of as long as 430 miles. That's more than three times the current range of the VW e-Golf electric vehicle the company recently started selling to the public and is substantially longer than the single-charge range of the Tesla Model S electric sedan. The batteries are also fireproof, making VW's potential decision one with an eye towards more vehicle safety. Solid-state battery technology, in which solid lithium electrodes are used instead of liquid electrodes such as those in lithium-ion batteries, are the subject of research at other automakers and suppliers as well. Toyota says they could be here by 2020. Recently, the cordless vacuum cleaner maker Dyson acquired a $15-million equity stake in Michigan-based battery maker Sakti3 with the idea of using the startup's solid-state batteries in its products. General Motors also has a minority stake in Sakti3, which was spun off from the University of Michigan.

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.
