EPA message to automakers: You're on notice

With top administrator Gina McCarthy speaking about the "moral obligation for climate action" on Friday, the Environmental Protection Agency announced it would ramp up its oversight of the auto industry in the wake of Volkswagen's emissions cheating. In a letter sent to manufacturers Friday, the agency said it would begin examining cars to see whether they contained defeat devices "in addition to the standard emissions test cycles." "We are putting vehicle manufacturers on notice." Exactly how the agency plans to test for these devices – which are not devices per se, but algorithms contained in millions of lines of software code that govern vehicle functions – remains unclear. Christopher Grundler, the director of the EPA Office of Transportation and Air Quality, divulged few details in how the agency would uncover so-called defeat devices used by cheaters. "Not today – or actually ever – I'm not going to be describing what new ways we'll be using to detect these defeat devices." Later, he said engineers will have to "come up with some clever ways to do this." The only insight he offered was that the EPA, California Air Resources Board, and Environment Canada would partner on testing more cars for emissions and anomalies. Grundler also said the EPA would diversify its testing fleet. In addition to relying on vehicles provided by manufacturers, the federal agency will now also borrow cars from "private citizens" and utilize rental cars for tests. "We are putting vehicle manufacturers on notice," he said. Joint investigations between EPA and CARB have "been very successful in protecting human health and the environment," said Janet McCabe, the agency's acting administrator in the Office of Air and Radiation. "But we also know, and the Volkswagen violations before us now make it clear, we need to adapt and step up our oversight." That may include an increase in on-road testing in addition to the five emissions tests now more relied upon. The EPA owns and maintains 23 portable emissions-monitoring systems like the one used by West Virginia University researchers who first detected elevated levels of nitrogen oxide emissions from two Volkswagen diesel vehicles. Right now, they're almost exclusively deployed to monitor emission from heavy-duty vehicles, whose NOx emissions "dwarf" the amount produced by light-duty vehicles, which produce less than 2 percent of the total, according to the agency's figures.

VW reveals Outback-rivaling Golf Alltrack ahead of Paris

The Volkswagen Passat Alltrack is getting a baby brother at this year's 2014 Paris Motor Show in the form of a new Golf Alltrack. Like its larger sibling, the little wagon is supposed to offer light-duty off-road driving ability combined with a more rugged look to show it off.
To give the Golf Alltrack that soft-road ability, VW is outfitting the wagon with its latest 4Motion all-wheel drive system from Haldex. The setup can decouple power from the rear-axle when not needed to save fuel. To further improve traction, the Alltrack gets VW's electronic differential lock, and the car can individually brake its inside wheel during hard cornering for better handling.
Volkswagen also wants the Alltrack to be able to visually show that it can handle getting away from the pavement, even though it starts life as a standard Golf wagon. That means jacking up the suspension an extra 0.75 inches and adding black moldings all the way around the car. There are also redesigned bumpers for the front and rear and silver underbody protection, plus new accents like anodized roof rails and silver mirror caps. The interior is essentially unchanged from the wagon, except for altered trim and Alltrack badges.

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.
