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.

A few pre-race notes and a lot of photos from the 24 Hours of Le Mans

The 82nd running of the 24 Hours of Le Mans is on.
Audi has won 12 of the last 15 events, the scion of Auto Union is trying to make it 13 this year. To do so, it will have to overcome a situation faced only three other times during its dominance of La Sarthe: underdog status. Toyota has won the first two races of the year and claimed pole for this race, the rumor being that this year it's Toyota's race to lose.
And then there's Porsche. It's been 16 years since the Stuttgart brand raced on the top rung at Le Mans, three years years since it announced its return, just a year since it acquired Mark Webber in a signing that wasn't subtle and a few months since we got eyes on the 919 Hybrid.

Porsche Boxster spied in the buff

Porsche is preparing a significant update to its entry level Boxster convertible, and while visually this might appear to be a simple refresh, the changes are more than skin deep. Following a number of rumors, Porsche will finally make the jump to turbocharged engines on a broad scale, and it starts with this new Boxster. According to our spies, it's the larger side intakes featured on this prototype that give away its smaller, force-induced flat-four engine. The dual exhaust pipes, meanwhile, say Boxster S to us, rather than just the basic model. Beyond the mechanical changes, this marks the first time we've seen the new Boxster completely free of camouflage. We can see that Porsche's stylists – famous for revolutionary designs slowly tweaking the same style for decads on end – adjusted the look of the front and rear fascias. We like the more aggressively canted headlights, which get the same four-pointed LEDs as its big brother, the 911. The slimmer taillights are a minor improvement on the inoffensive lamps fitted to the current car, and serve to take some attention off the all-plastic exhaust surround, which is much more simply styled than the current car's. It should also be noted that the aesthetics featured on the new Boxster are very, very likely to be transferred directly onto the new Cayman. You can check out our full gallery of shots of the all-new, totally undisguised Boxster in the gallery up top. Expect to see the new roadster around this time next year, with a debut at the 2016 Geneva Motor Show likely. Related Video:
