VW adding particulate filters to gas engines

Volkswagen is working hard to overcome the PR disaster that is its diesel emissions scandal, and part of its efforts is focusing, weirdly, on petrol engines. Starting in June 2017, the embattled German automaker will add particulate filters to the gas-powered Volkswagen Tiguan and Audi A5. The change will eventually impact nearly every direct-injected gas engine the VW Group makes. Audi? Particulate filter. Seat? Particulate filter. Even Bentley is going to get the tech, all in a bid to reduce soot emissions by 90 percent. In fact, by 2022 VAG expects 7 million of its vehicles to boast the emissions-cleaning tech, which has long been a fixture on diesel engines. "Following increases in efficiency and lower CO2 output, we are now bringing about a sustained reduction in the emission levels of our modern petrol engines by fitting particulate filters as standard," Volkswagen Group research and design boss Dr. Ulrich Eichhorn said in a statement. "In the future, all models will be equipped with the latest and most efficient SCR catalytic converter technology." VW's initial rollout focuses on the 1.4-liter, turbocharged Tiguan and the 2.0-liter, turbocharged A5. Considering the popularity of the 2.0-liter across the VW range, we'd expect it's only a matter of time before VW expands its particulate filters tech to additional gas-powered vehicles.

2015 Volkswagen Golf: Green Car of the Year?

As you may recall, VW's compact Golf was voted 2015 North American Car of the Year by a jury of 57 veteran automotive journalists (including this one) and named Car of the Year by Motor Trend and Yahoo Autos and Best Car to Buy 2015 by Green Car Reports. "The range of green options in the 2015 Volkswagen Golf range is hard to beat," says Green Car Reports editor John Voelcker. "With more fuel-efficient gasoline engines, a new TDI diesel option that comes close to real-world hybrid mileage levels, and the all-electric VW e-Golf, the 2015 Golf gives buyers a good-better-best menu of options for driving green." The car was also a finalist for Green Car Journal's "Green Car of the Year," but ultimately lost to the BMW i3 EV. When I saw GCJ editor Ron Cogan at last November's Los Angeles Auto Show, he asked me to guess which finalist would win. Based on its efficiency and versatility, I guessed the Golf. He smiled but the next day, he named the i3 the winner. Okay, the technically impressive, carbon-fiber-bodied i3 is a formidable green machine wearing a prestige German label at a semi-affordable ($43,000) price. But it comes in just one (somewhat odd-looking) body style with a choice of all-electric or range-extending electric powertrains, and its EPA-official ranges are 81 miles for the former and just 150 for the latter, costlier version, which totes a tiny (647cc) 34-hp two-cylinder BMW motorbike engine in its tail. By contrast, the 2015 Golf comes in 3- and 5-door hatchback and even more practical Sportwagen body styles and offers a wide range of eager yet fuel-thrifty turbocharged gas and clean-diesel engines, most with a choice of manual or automatic transmission. An all-electric e-Golf, one of the best EVs we've yet driven, is also available in some areas, and that will be followed, VW says, by a hybrid, a plug-in hybrid and even a CNG-powered model. No question this all-new seventh-generation 2015 VW Golf is easily the best ever. A bit larger, roomier, aerodynamically slicker and more fuel efficient than the Gen VI Golf it replaces, it's built on an all-new modular platform and boasts an amazing range of models, powertrains and features.

VW modular platform strategy goes all-in on EVs

The Volkswagen Group has already revealed or put on sale a broad slate of new electric vehicles: the E-up, the E-Golf (shown above), the Porsche 918 Spyder, the Panamera S E-Hybrid and the XL1. In 2014, there will be at least six more models, including the A3 Sportback E-Tron. And after that? Well, to hear Rudolf Krebs, Group Commissioner For Electric Vehicle Drive Systems, tell it, VW's future is full of plug-in goodness. "With our platform strategy, it is quite easy to bring a lot of electrified vehicles to the market for the different brands in a very short time," he said. "We try, with a minimum of those components, to produce a maximum number of variants of cars" That strategy starts with three platforms: MQB for small cars, MLB for midsize models and MSB for sporty and premium products (there's also the NSF for cars like the E-up). Speaking to AutoblogGreen, Krebs said VW has designed modules, things like engines and electric components (think: AC compressor, on-board chargers and battery management systems), to be used across all three platforms and across all brands all. "We try, with a minimum of those components, to produce a maximum number of variants of cars," he said. "This is only possible if, at an early stage of the design of new vehicles, we implement the idea that these cars are not only designed for gasoline and diesel powertrains but that we can also include CNG concepts, flex-fuel concepts, pure electric vehicles or plug-in hybrid vehicles. With minor changes in the body in white, we can produce those vehicles, bumper-to-bumper, in one factory." "VW wants to be the leader in the electrification of vehicles" In this way, customers can choose the powertrain that they want, or whatever powertrain their local regulations demand. Politicians have already put a lot of pressure on the automotive industry, with ever-stricter CO2 regulations coming into effect in all of the major markets. In the US, the fuel economy regulation numbers require the equivalent of 101 grams of CO2 emissions per kilometer by 2025. Europe, it's 95 grams by 2020. And China, which is asking for 118 grams by 2020, will be a tough scenario, Krebs said. Today, by optimizing conventional technologies and supporting things like CNG and biofuels, more than 300 VW Group models emit less than 120 g/km. A hundred of those are even under 100 g/km. But this is not sufficient, and VW admits that conventional powertrains will not be not enough.
