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.

The Bearable Lightness Of Being
Start with a standard Porsche 911 Carrera and its 350-horsepower, 3.6-liter flat six-cylinder engine. Bore a crepe-thin slice of aluminum from each cylinder to get to 3.8 liters, add a wider track out back and two extra exhaust pipes and voila, you can append an S to the Carrera's name. Hang two sets of wet, multi-disc clutches along its spine and you can make that a 4, or a 4S. Bolt on two forced-induction compressors and piping, add two fender vents and comically wide rear tires and you've redeemed your ticket to a Turbo. Increase the boost pressure and swell the corral to 560 horses and you have the Turbo S, which is the Virginia Slims of the 911 line-up because it's come a long way, baby.
Or you can go in a different direction. At that second stop, grab the 3.8-liter and cart it over to the engineers at Porsche's development center in Weissach, Germany. If racing were meat, they would be among the alpha carnivores. The baseboards in their homes are probably painted with miniature billboards for motor oil and vintage cigarettes along the straights, red-and-white stripes around every corner.

The entire Porsche 911 history in under 90 seconds

Over more than 50 years Porsche has taken a terrible idea - hanging an engine behind the rear wheels so that the car will try to go backwards through corners - and turned it into an automotive icon. One way that happened was keeping that unmistakable shape. As you'll see in the video above, the proportions are true to the original even with the relatively radical changes with recent models. The animation includes price and power figures, and even has the model designations, so you can keep up in conversation when a Porschephile starts rambling about random numbers.
