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 Panamera gets new diesel in time for Frankfurt

Diesel may not be the first thing that comes to mind when you think of Porsche, but in the European market - that vital one which Porsche calls home - diesels are indispensable. Particularly when you're trying to extend beyond niche sports cars and into the mainstream luxury sedan market as Zuffenhausen has with the Panamera. In fact, diesels account for 15 percent of Panamera sales worldwide (even though they're not offered Stateside), so to keep oil-burning customers happy, Porsche has announced a series of upgrades.
Set to be unveiled in the flesh at the fast-approaching Frankfurt Motor Show, the new Panamera Diesel packs 300 horsepower. That's 50 hp (or 20 percent) more than the model it replaces, significantly dropping the 0-62 sprint from 6.8 seconds to 6 flat, and raising top speed from 152 miles per Autobahn-crunching hour to 161. While they were at it, Porsche's engineers also fitted the rear differential with torque vectoring (previously reserved for gasoline-burning models) and retuned the transmission and suspension.
You can delve into the press release below for all the details - including the new model's improved towing capacity! - but the reality, for better or worse, is that the Panamera Diesel isn't offered here. So if you've been celebrating Labor Day (or even Labour Day, for our friends to the north) like we have, don't go looking for it at your local dealer, who will have only a Cayenne Diesel to show you instead.

Porsche Cayman gets a new face

We've already seen photos of the facelifted Porsche Boxster out testing, but we're now seeing these same changes making their way onto the hardtop Cayman coupe. Cosmetically, the next round of Porsche's smallest sports cars isn't vastly different, with redesigned headlamps, LED running lights (like its big brother, the 911), and new taillamps that actually aren't visible on the prototype seen here.
The big news for the updated Boxster/Cayman range is the long-rumored four-cylinder engine. Recent reports suggest we could see four-pots with displacements of 1.6, 2.0, or 2.5 liters, and with output ratings as high as 360 horsepower. Of course, these new four-cylinder mills would be both turbocharged and direct-injected.
It's unclear whether or not the six-cylinder engine range will also be updated when this new Cayman comes to market. In any case, we expect to see it bow in the relatively near future. Stay tuned.
