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.

Porsche tipped to reveal purist's 911 R in Geneva

Update: The 911 R dam has broken well ahead of its official reveal at Geneva. Stay tuned for full coverage, but take a look at this image from Twitter user @PistonHeads and let us know what you think in the comments below. This content is hosted by a third party.

With much of the 911 family going turbo, there's room in the lineup for a purist's Porsche: a naturally-aspirated, rear-drive, manual-only model that'll essentially be a stripped-down GT3. The latest reports indicate that this model, initially expected to be called the 911 GT but now more likely to get the 911 R moniker, will be unveiled in Geneva. It's also tipped to wear skinnier tires that will sacrifice grip for a more linear driving experience, and jettison the big wings in favor of a sleeker, more classic profile. What that all boils down to is a GT3 in its essence, and it will likely pack the non-turbo engine from either the GT3 or GT3 RS (pictured above) – or some version thereof. Recall that both the GT3 and the GT3 RS are PDK-only, although Porsche has decided that the next-generation GT3 should give customers the option of shifting for themselves. According to Motoring.com.au, which recently spoke to 911 product line manager August Achleitner, the purist's 911 will be unveiled at the Geneva Motor Show less than two months from now. "Come to Geneva and you'll find out," said Achleitner "but for now this is all I can talk about." Don't get your hopes up too much, because production is expected to be severely limited, with the entire production run likely to be pre-sold. Related Video:

'Faster. Farther.' dives into the history of Porsche racing tech

No doubt, Porsche has produced some of the best endurance racecars around, such as the turbocharged, slant-nose 935 of the 1970s and the ground-effects-enhanced 956 and 962 of the 1980s. But the company's most famous racecar, its first overall winner at the 24 Hours of Le Mans, was the 917.
The 917 embodied many of Porsche's technological achievements up to that point, such as the company's first 12- and 16-cylinder engines (the flat-16 was never used in competition), fiberglass bodies that implemented early aerodynamic practices and the use of new, exotic materials, such as magnesium and titanium.
The racecar was commissioned by the head of Porsche Motorsports, Ferdinand Piëch, to win overall at the 24 Hours of Le Mans in 1970, after he realized a loophole in the rules that allowed cars to compete with engines up to five liters in the Sport category if they were also production models. Piëch saw opportunity: the top prototype class was restricted to three liters; the production minimum to compete in Sport was 25 cars. And so, with much effort, Porsche assembled 25 "production" 4.5-liter 917s and had them parked in a neat line for the race inspectors to verify their legitimacy. It didn't take long before people realized the new Porsches were much faster than the prototype racers, with a top speed approaching 250 miles per hour.
