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 919 Hybrid revives Porsche's factory Le Mans efforts

After months of teasing with camouflaged testers, Porsche has finally unveiled its prototype entry for the 2014 World Endurance Championship, the 919 Hybrid. Porsche, you may recall, hasn't had campaigned a factory team at Le Mans in years, so the 919 is nothing less than their recommitment to endurance racing.
Combining a 2.0-liter V4 (yes, a V4) that revs to 9,000 rpm, the 919 produces around 500 horsepower with a pair of energy recovery systems. The first system recovers the heat energy from exhaust gasses as they pass through an electrical generator, while the second system is a bit more familiar. Using a setup similar to what is found on the production 918 Spyder, a generator on the front axle recovers kinetic energy from the brakes, which is subsequently stored in a battery system. That power can then be sent to the front wheels at the driver's command, effectively turning the 919 into an all-wheel-drive racecar.
Despite these various forms of motivation, Porsche doesn't claim to be seeking outright power supremacy, with Chairman Matthias Müller saying, "In 2014, it will not be the fastest car that wins the World Endurance Championship series and the 24 hours of Le Mans, rather it will be the car that goes the furthest with a defined amount of energy. And it is precisely this challenge that carmakers must overcome. The 919 Hybrid is our fastest mobile research laboratory and the most complex race car that Porsche has ever built."

Porsche to only build next Panamera in Leipzig?

Manufacture of the next-generation Porsche Panamera could be moving, if a report from Reuters is true. The current-generation Panamera range has its bodies welded together and painted at a Volkswagen facility in Hanover before being shipped to Leipzig where final assembly takes place.
According to Reuters, Porsche is looking to cut VW out of the equation and focus production of the Panamera in Leipzig. While this could cost 800 of the 14,300 workers at Hanover their jobs, it's not entirely clear what Porsche stands to gain by the move. It recently invested 50- million euros (about $680 million at today's rates) on a paint and body shop for its Leipzig factory, ostensibly so the facility could have Macan production underway by that car's spring 2014 on-sale date. If the facility was also designed with next-generation Panamera production in mind, then Porsche's decision to put all of its eggs in one basket could make a lot of sense. It currently ships the semi-completed Panameras from Hanover to Leipzig, a distance of around 160 miles by road, and presumably it's a costly and time-consuming process.
The Leipzig factory produced 27,000 Panameras last year, although it's unclear just what its production capacity really is. Besides the Panamera and the upcoming Macan, the factory also builds the Porsche Cayenne.
