CARB has 20 days to confirm VW's 3.0-liter TDI emission fix

VW's diesel scandal has been in the headlines since last September, but solving the problem it proving difficult. Volkswagen Group has submitted a proposal to the California Air Resources Board (CARB) and the Environmental Protection Agency (EPA) to fix about 85,000 vehicles with the 3.0-liter diesel V6 in the US, Reuters reports. CARB now has 20 business days to test if the plan actually reduces emissions. If accepted, VW could finally begin a recall and end the stop sale on vehicles with these engines. In a statement, CARB pledged to, "respond following a thorough and complete review to make sure the plan addresses the presence of the illegal defeat device and follows the necessary environmental, vehicle and public health and safety regulations." Neither CARB nor the EPA outlined the proposed repairs, but Porsche CEO Oliver Blume already suggested the fix for the engine in the diesel Cayenne. Examples from 2013 and 2014 allegedly need a new catalytic converter and software update, and those from 2015 and 2016 only need the improved code. It's not yet clear whether this procedure would work for all models with the 3.0 TDI. While the EPA issued the notice of violation against VW's 2.0-liter four-cylinder diesel in September, the first one for the 3.0-liter V6 came in early November. By the end of the month, the agency broadened the scope to about 85,000 vehicles, including some examples of the VW Touareg, Audi A6, A7, A8, Q5, Q7, and Porsche Cayenne. The affected companies issued stop sales on new models with the engine. Audi eventually admitted to regulators that it didn't disclose three auxiliary emission control devices in the powerplant's code and promised to develop a software update to fix the problem. CARB gave the automaker 45 business days to submit the proposed solution. If accepted, this repair would allow VW Group to end part of the emissions scandal, but there's no guarantee the regulators consent to this solution. Just a few weeks ago, CARB looked at the automaker's plan to fix the 2.0-liter TDI and rejected it, claiming a lack of detail.

How VW's hyper-efficient XL1 will influence the next Golf

In 2007, the European Union mandated fleet average CO2 emissions of 158.7 g/km. For 2015, that figure will drop to 130 g/km, and the target for 2020 is an ambitions 95 g/km. Thanks to some German politicking, that target will be phased in from 2020 to 2024, but it will still apply to 80 percent of passenger cars in that first year. In US miles per gallon, that's the equivalent of going from about 35 mpg to 42 mpg to 57 mpg. The current Volkswagen Golf is rated from 85 g/km of CO2 to 190 g/km depending on model - and zero for the e-Golf, so for the next-generation MkVIII hatch due in 2019, to meet the goal, Volkswagen engineers will need to introduce a bunch of new tricks. According to a report in Autocar, VW be mining its hyper-efficient XL1 for some of them.
Predictions for the next Golf include a variable-compression engine, an electric flywheel and an electric turbo, along with taking greater advantage of coasting. Volkswagen could be getting help from Audi with the electric turbo and variable-compression engine and electric turbo, with Audi already having shown off the former and brand technical boss Ulrich Hackenberg confirming the VW Group is working on the latter. It's possible the flywheel system could also have the mark of The Four Rings: Autocar mentions a British system that Volvo is testing, but the R18 e-tron Quattro racer has been using one for years.
The need for such features is because the company won't be able to net enough future gains from just aerodynamic improvements and advanced materials. As price will be a factor (the regulations are expected to "add hundreds of euros to the cost of building a car"), adding much more aluminum or carbon fiber is an unlikely option. We're told the next generation won't be longer or wider than the current car, and being Europe's most popular model, VW doesn't want to make a big bet on futuristic aero, but the report says the MkVIII will "likely" have "the most aerodynamic treatment yet seen on a production vehicle," the area where lessons learned from the XL1 will truly be seen.

2015 Volkswagen Golf R [w/video]

Volkswagen hired a photographer to come shoot the handful of journalists that it brought to drive the 2015 Golf R at Buttonwillow Raceway north of Los Angeles. This fact, though unremarkable in and of itself, was something I hadn't noticed until I was well into my track time – probably ten laps deep on a day that would see me run twice that number. In any event, I noticed the intrepid shooter as he was sprinting from one side of the track to the other somewhere before Turn 2, while I was barreling down the main straightaway, still looking through Turn 1. In the roughly two-mile configuration of the track that I drove, Buttonwillow is a big, wide-open circuit, largely flat and with excellent overall visibility. On that layout, and just hours into my Golf R experience, I'd already become confident in endeavoring to push the limits of VW's latest blistering hatch. In fact, the easy nature of driving the thing quickly had me overestimating my pace. So when I saw the photog sprint across the tarmac I instinctively slowed way too much, way too early for Turn 1. Looking back at the incident after I'd pitted for the session, I laughed at myself, knowing I'd have had to be driving almost double my actual speed to put the camera guy in any real danger of being hit. But the experience crystallized what my full test of the R bore out: this is a car that makes you feel much faster than you otherwise would, at least in a competition setting. The 2015 Golf R is an uber hatch that will flatter those hyper-enthusiasts passionate enough to splash out on its steep price tag, but without threatening sales of core models like the GTI and its ilk. That's a good thing for the VW fanboys, to be sure, and, I'd argue, a great thing for the strength of the German brand overall. {C} The R felt both placid and comfortable while I clicked off highway miles in search of the racetrack. My test in California had at least two things in common with the First Drive feature that Steve Ewing brought us with the Golf R in Sweden. First, we both drove European specification cars (though mine didn't suffer from the same sticker abuse that Steve's did). Second, we were both somewhat limited in terms of driving the car in varied, real-world situations. My street route consisted almost entirely of tracking California's I-5 north out of Los Angeles; which any Angelino will tell you is a less-than-riveting mode of travel.
