A beastly 1979 Porsche 930 is unleashed by Petrolicious

The 911 Turbo held a special place in Porsche's lineup for decades. Much of the mystique came from its performance potential, but that huge capability also required a deft hand and foot to keep things in check. These days even the most basic 911 packs turbos, but Grant Karnes and his 1979 Porsche 930 demonstrate why the early models remain classics in the latest video from Petrolicious. Karnes says he gets attention from everyone he passes in his 930, and it's easy to understand why. Even before the coupe comes into view, the upgraded, turbocharged engine pops and crackles with a wonderfully raw sound. People then see the Porsche's classic combination of wide fenders and a big rear spoiler. Karnes also adds a vintage racing vibe with Martini decals on the hood and doors, and his license plate tells folks exactly what kind of machine this is. Plus, if you happen to spot this car at night, the exhaust can shoot bursts of flames. Porsches are a fairly common subject in Petrolicious' videos, and they run the gamut from well-worn classics to heavily modded canyon carvers. Karnes' 930 leans more in the latter direction but still maintains a vintage look. He promises the coupe is always exciting to drive, and this clip does a fantastic job of showing why.

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.

2016 Porsche 911 GT3 RS First Drive [w/video]

Imagine a regular Porsche 911 GT3 in your garage, parked next to a brand-new, no-options Boxster. Now imagine your garage with just a 911 GT3 RS inside. From a cost standpoint, you could have either for roughly the same amount of money. Trying to figure out if the RS goodies are worth the $50,000 over a standard 911 GT3 – roughly the price of that no-frills Boxster – might drive you mad. We're trying to suss this out at 120 miles per hour on the long downhill back straight at Road Atlanta. It's pouring. Rivulets of water are streaming across the track. Ahead, in a 911 Turbo leading the pack, is Le Mans- and Daytona-winning driver David Donohue. He's helpfully warned us to avoid nipping the curbing, since that's where water pools. Hydroplaning could end someone's day. Through the blinding spray, Donohue mercifully has reduced the pace. There's enough speed to evaluate what the GT3 RS does well, which is essentially everything. There's also enough time to figure out what sort of sports car this is. Horsepower swells to an even 500 and torque to 338 pound-feet – bumps of 25 hp and 14 lb-ft over the GT3. As is fitting and proper for the traditional sports car par excellence, at the top of the large and expensive 911 heap is the GT3. While the base is shaken by the encroachment of turbocharging on basic 911 models, the summit is, like mountain air, all-natural. The GT3 was subject to a beyond-galling recall due to faulty con-rods with a penchant for ventilating crankcases and starting catastrophic fires, but storms crash upon every peak. Progress is inevitable for German engineers. The GT3 RS is the 911 reforged in those embarrassing fires. The GT3 itself was a false summit, but the RS is the real deal. Underneath the very purple bodywork, this is a lither and more athletic thing than the already superb GT3. Lightweighting is accomplished with a healthy dose of carbon fiber on the engine cover and the frunk. The roof, with a slick-looking depressed slash running longitudinally, is made of magnesium. That serves to lower the center of gravity, Porsche assures us. Even the rear silencer is made of titanium. In total, the RS is 22 pounds lighter than the GT3 it's based on – seemingly small gains considering all the exotic materials, but less so considering what's been added back. The RS is also more powerful, thanks to a 200cc displacement increase.
