Porsche announces four flavors of updated Cayenne [w/video]

The new Macan may be getting all the attention lately, but Porsche hasn't forgotten about its larger crossover - the one that put it on the map in 2002 and on the road to profitability, with over half a million sold so far. So to keep the Cayenne at the top of its game, Porsche has announced several key upgrades for the 2015 model.
For starters, Porsche has updated the Cayenne's appearance with new front- and rear-end styling. The front bumper, fenders and hood are entirely new, with air fins flanking the nose to direct air into the intercoolers (each model now being artificially aspirated), and new bi-xenon headlamps and daytime running LEDs on every model but the Turbo, which goes all-LED. Around back there's also new taillights, tailgate handle, lower rear fascia and exhaust pipes. Meanwhile the interior has been upgraded with a 918-derived sport steering wheel and reformed rear seats with available ventilation.
The bigger news is under the engine bay, where Porsche is offering four choices. The base model is gone as the range starts with the Cayenne Diesel, followed by the Cayenne S, the new Cayenne S E-Hybrid and the top-of-the-line Cayenne Turbo. The Diesel model carries over the same 3.0-liter turbo diesel with 240 horsepower. The Cayenne S however packs a 3.6-liter twin-turbo V6 that's similar to the one found in the Macan Turbo and packs the same 406 lb-ft of torque but more power at 420 hp, 20 more than either its little brother or the model it replaces to reach 62 mph in 5.2 seconds.

Porsche 911 GT3 RS getting all-new atmospheric engine

Porsche surprised many of its most puritanical enthusiasts when it took a decidedly more usable approach with the current 911 GT3. But when the new GT3 RS debuts, it promises to be a much more extreme departure. And a big part of that comes down to the engine. At the Detroit Auto Show this week, Auto Express spoke with Porsche R&D chief Wolfgang Hatz – who also happens to be head of engine and transmission development for the entire Volkswagen group. Hatz revealed that Porsche has developed a completely new engine for the GT3 RS, and while previous rumors suggested the RS would go turbo to fill in for the lack of a GT2 (and make the most out of its displacement), Hatz confirmed that it will be naturally aspirated. Considering that Porsche rarely goes downwards when it comes to 911 engine displacement, only upwards, we'd expect the new RS to pick up where the previous 4.0 left off. The new GT3 RS is also expected to pack a more extreme suspension, aero and stripped-out interior, but those hoping for an old-school approach may be disappointed to learn that the new RS will (at least at launch) only be available with the seven-speed dual-clutch transmission – though a manual version could follow if there's enough demand. In a related development, Hatz also hinted that the Cayman GT4 could debut at the Geneva Motor Show in March, with an even more extreme approach than the previous Cayman R. The new top-of-the-line Cayman is reportedly being developed to comply with GT4 class racing regulations but be fully homologated for road use. Related Video:

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.
