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 spotted testing next-gen Panamera in the snow

It's winter testing season in northern Sweden, and the latest spy shots our paparazzi on the ground have brought us is the upcoming Porsche Panamera testing in the cold and snow. The upcoming new four-door Porsche, spied wearing only minimal camouflage, appears to have a more elegant and sloping roofline than the existing model. Other details like the lights, mirrors and grille openings look fairly consistent with what we've been seeing on Porsche's other models as they've trickled out. Based on the new MSB platform, the new Panamera is set to share its underpinnings with the next Bentley Continental and possibly an Audi variant as well – though the prospect of a Lamborghini version to follow the Estoque concept seems to be off the table. The new platform will, however, make the new Panamera lighter than the current model. A new range of V6 and V8 engines are expected to provide motivation, driving the rear wheels or all four, along with the available e-hybrid system. Porsche's first four-door sedan was introduced in 2009 and underwent a facelift in 2013, so the all-new second-generation model should arrive sometime later this year or next as a 2017 model. This new model could provide the impetus for Porsche to put the Sport Turismo shooting brake version into production as well, and maybe – just maybe – a two-door coupe and possible convertible versions to follow in the footsteps of the 928.

Porsche offering new tire option for Carrera GT

Let's face it: finding new tires for older cars can be challenging if tire manufacturers have stopped carrying the right sizes (this writer went through Hell to find a set of 205/60-13s). But what about tires for low-volume supercars, which use sizes that often won't fit on high-volume production vehicles? The Porsche Carrera GT isn't that old and tires are still available in the correct sizes, but the German automaker has shown its support of keeping them on the road by working with Michelin to give owners yet another tire option. Enter the Carrera GT-specific Pilot Super Sport.
It's common knowledge that tires are one of the most important pieces of the performance puzzle, and Porsche claims that the PSS tires, sized 265/35ZR-19 front and 335/30ZR-20 with Porsche's "N0" rating, will improve the Carrera GT's handling and stability all the way up to its claimed top speed of 205 miles per hour. That's important for a car with razor-sharp handling characteristics. They'll also net drivers a 10-percent increase in fuel economy on regular roads and up to 20 percent on racetracks, Porsche says.
The PSSs use cutting-edge tire technology to harness the Carrera GT's 610-horsepower. They have a dual-compound tread that's different from the inside of the tire to the outside, which, Porsche says, helps steering precision and increases maximum grip. Aramid fibers, which are lightweight but just as strong as steel, are used in the tire's belt to reduce unsprung weight.
