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.

Audi A3 E-Tron could launch in October in US

When we test drove the Audi A3 E-Tron plug-in hybrid in Europe last summer, Audi was talking about the vehicle's introduction in the US, but left the exact date up in the air. Summer or Fall 2015 was as specific as anyone was willing to get. Now it looks like the plug-in will arrive in October. One of the rumors we heard over the last few months was that the A3 E-Tron was not ready for the US because of poor cold-weather performance. From what we've heard, under a certain temperature limit, the engine needs to kick in at all times, no matter what the battery state of charge is, and some European A3 E-Tron owners are disappointed that their EV sometimes isn't all that electric. Audi's solution needs to take into consideration how to balance utilization of battery power in less-than-optimal temperature ranges with passenger comfort and how any excess battery use impacts longevity. Audi's "fairly conservative" position will "ensure the long-term credibility of the E-Tron platform and plug-in technology." - Brad Stertz Brad Stertz, the corporate communications manager for Audi of America, told AutoblogGreen that, "Audi is taking a fairly conservative position to ensure the long-term credibility of the E-Tron platform and plug-in technology, while still creating the best experience for our drivers in each region. Overall, I think it is safe to say low temps affect performance in all vehicles to some degree, but that plug-ins face unique challenges that we will continue to work through with the A3 e-tron and other plug-in models to follow." Stertz also said in April that the US configuration for the A3 E-Tron was still being fine-tuned. For example, there were some software differences under consideration to meet US driving preferences. Looks like we only have four more months to wait and see. Related Video:

More next-gen Audi TT details revealed

We still only have rumors about the third-generation Audi TT said to be scheduled for launch in late 2014, but based on a report in Car and Driver, we know a tiny bit more about it. The base engine will be the 2.0-liter turbo four-cylinder with direct injection, but horsepower is said to be 220 horsepower - that would make for a nine-hp jump over the current output. The TTS would get an even larger power boost, going from 265 currently to 300 hp. The TT RS would stick with it's 2.5-liter five cylinder, with output increased from 360 to 380 hp. If Audi includes a nice dose of the go-light engineering involved in the TT Ultra Quattro, these horsepower numbers might be even more impressive.
As with the TT concept and first-generation production car, though, it sounds like the brand is concentrating on aesthetics. It's been widely reported that Audi wants to reclaim the juju conjured by the original TT, and while we still don't know what that means outside, CD reports that the interior gets simplified, "futuristic-feeling" styling thanks to instruments served up on a TFT screen. Remember, the first Audi TT had a cockpit that Car magazine dubbed simply, "The Cabin."
About a year after the coupe comes, the Audi TT Roadster will show up and should be joined by the next A5. The news for the next version of the subtly beautiful coupe is the arrival of a plug-in hybrid with torque vectoring via an electric motor for the rear axle. Beyond that is wilder speculation of an A9, which might be called Q9, and which was the four-door-coupe flavor of the month two years ago when it was possibly going to share a platform with the Lamborghini Estoque. According to the CD story, the thinking now is around "a combination of fastback and crossover proportions," a two-fer we've yet to see any carmaker pull off without making us go, "Oh. I see."
