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 rolls out new Macan GTS with 360 horsepower [w/video]

Porsche is expanding both its Macan line and its range of GTS models with the launch of the new Macan GTS. The new performance model slots in between the Macan S and Macan Turbo, packing a mightier punch, upgraded equipment, and sportier styling. The enhancements naturally start under the hood, where the Macan GTS packs a 3.0-liter twin-turbo V6 good for 360 horsepower and 369 pound-feet of torque. That's 20 more horses than the Macan S but 40 less than the Turbo, driving all four wheels through a seven-speed dual-clutch transmission. The result is a 0-60 time quoted at 5.0 seconds (or 4.8 with the optional Sport Chrono pack) and a top speed of 159 miles per hour. You know, just to stick it to the other German cars that limit themselves to "only" 155. Of course, Porsche didn't just tinker with the engine and leave it at that. Compared to the Macan S, the GTS features a retuned air suspension, recalibrated electronics, ride height lowered by 10 millimeters, and 20-inch wheels with a matte black finish. The interior also benefits from specific sport seats with Alcantara trim, and the new Porsche Communication Management system. There's a new exhaust system and upgraded brakes, as well. The Macan GTS is just the latest such model to join the range, alongside GTS versions of the Boxster, Cayman, 911, Panamera, and Cayenne. While sales of the new Macan GTS start today in its home market, US customers will have to wait until March to place their orders. MSRP is listed at $67,200 (plus destination), pretty evenly splitting the difference between the existing S and Turbo models. This content is hosted by a third party.

Porsche 911 Aerodynamic prototype cheated the wind ahead of its time

You might think that sports cars would have the lowest drag coefficient of all cars. And yes, they do tend to be more slippery than, say, SUVs or convertibles, but the sleekest vehicles on the road tend to be EVs, hybrids and luxury sedans. Sports cars, on the other hand, have aerodynamically detrimental needs for downforce and additional engine cooling. Still, the Porsche 911 is better than most, and has only gotten more so over the years. Its relatively narrow track and compact form mean it has a smaller frontal area than some other sports cars, and the gradual sweeping back of its headlights and windshield have only augmented its capacity for cheating the wind.
This 911 prototype, however, is even more aerodynamic than most. It's based on a "G model" 911 from 1984, but employed such features as covered wheels, a new rear spoiler and a reprofiled front end to drop its drag coefficient from 0.40 to 0.27, making it as slippery as a modern sedan and better at cheating the wind than just about anything built up to that point, save for maybe the Tatra 77, Citroën SM or Tucker Torpedo.
Elements of this prototype ended up gradually making it into production Porsches for years to come, and you can clearly see early influences on the second-generation 964 and even on the 959. It's featured here as the latest installment in a video series on rare historic Porsches unearthed from the company archives, following previous clips that featured a rare V8-powered 911 and a mid-engined 911 prototype. Scope out the latest episode in the video below.
