Porsche 911 going all-turbo this year save for GT3 and GT3 RS

The coming Porsche 911 GT3 RS will represent another high-water mark for the brand, and another milestone. Its 500-or-so horsepower and extreme aero are predicted to lop more than five seconds off the 7:20 Nurburgring lap time of the current GT3, making it "comfortably less" than 7:20. Beyond that, its naturally-aspirated 3.8-liter will form the basis of the turbocharged engines going into the standard range of 911s later this year as 2016 models. That's right – if you're looking for a sub-GT3 911 that gulps its air without compressed assistance, then you've only got a few months to get a new one into your garage. Emissions regulations are the reason, of course, with Porsche's R&D chief Wolfgang Hatz saying that, "Every new model will have lower CO2 than before," and "if you look at euro per g/km, then it's turbo." We don't know what the engine lineup will look like, however; a few months ago Car reported that the base 911 would get a smaller-displacement version of the engine, while the S would stick with 3.8-liter displacement and jump to 520 horsepower, which is the same as the current Turbo. After that, Hatz said, "at the end of the decade electrification has to be the next huge step." That means a hybrid 911 is being cooked up somewhere. Yet even as the brand leaps into the new, there's a chance it could dip a toe back into the old: the 911 GT3 RS will launch with a PDK, but Hatz's team is considering adding the option of a seven-speed manual. Elsewhere in the range, the Cayman GT4 is being engineered by Porsche Motorsport as an entry-level racer, with more power than the current Cayman GTS to go with some serious weight loss. They are also developing a track-only model for privateers. The standard Boxster and Cayman will get turbocharged flat-four engines, but there'll be a sporty Boxster that also loses weight and gets more power than the 325-hp Boxster GTS. And that mid-level supercar that's been floating in the ether for years and supposedly sent to purgatory again just last November? It's on the way by 2020 "at the latest," and will use a version of the new V8 that will eventually go into the Cayenne and Panamera.

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.
