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 Cayman GT4 Clubsport delivers track-only thrills for $165K

Among the cars on display in Los Angeles, production and concept cars are normal. Racers, though, are rather rare. And race-specific models that can be had for less than $200,000 are more or less unheard of. Don't tell that to Porsche, though, because the German automaker has introduced the new Cayman GT4 Clubsport for the relatively reasonable sum of $165,000. For that supercar-worthy price, you'll be getting a number of race-derived parts. As we covered in our preview post, that will include a strong roster of safety equipment, including a full roll cage and six-point harnesses that will keep you pinned in a purposeful racing bucket. The standard 18.5-gallon fuel tank can be replaced with an optional 26.5-gallon setup, while a central fire extinguisher keeps things from getting too hot out on the track. Mechanically, the Clubsport adjusts the Cayman GT4 formula for the track. The road car's 3.8-liter flat-six engine is still mounted amidships, but it's paired with super-quick, six-speed dual-clutch transmission, the critically acclaimed PDK. It's the suspension, though, that sees the most dramatic changes, as Porsche has pressed the front and rear strut suspension from the 911 GT3 Cup into duty for the GT4 Clubsport. The new system is lighter, and contributes to the track star's 2,866-pound curb weight. That's nearly a 100-pound drop over the road car. A set of four 15-inch steel rotors clamped by six-piston calipers up front and four-piston units in the rear should deliver stopping power as impressive as the cornering and acceleration. Amateur racers interested in the new coupe can purchase it directly from Porsche Motorsports North America for competition in the 2016 racing season. Homologation is still being hammered out, but Porsche expects the GT4 Clubsport to be certified for the "VLN Long Distance Championship Nurburgring, the Ultra 94 GT3 Cup Challenge Canada, the PCA Club Racing Cayman GT4 Clubsport Trophy East as well as for other club-level competition events around the world." Read on for the official press release. New Porsche Cayman GT4 Clubsport for the racetrack World premiere in Los Angeles LOS ANGELES, Nov. 18, 2015 /PRNewswire/ -- Porsche has added a new sports car for amateur and club racing to its Motorsports fleet: The Cayman GT4 Clubsport celebrated its world premiere today at the Los Angeles Auto Show.

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.
