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.

Xcar spots the differences of refreshed Bentley Continental GT

Bentley unfurled the details about the refresh of its second-generation Continental GT earlier this year and gave the high-speed cruiser an official unveiling at the Geneva Motor Show. Even with the tweaks, the British brand kept its most popular model very refined, though. If you're still having a problem spotting all the differences for this posh coupe, Xcar is here to help with an informative new video. Rather than putting the focus exclusively on driving impressions, Xcar really leans heavily into listing the specific updates for the latest Conti GT. Beyond the updated front end, likely the most obvious change for the refreshed model are the big, B-shaped pieces of chrome trim around the side vents. If not obvious already, they make it exceedingly clear that this is a Bentley. A neat touch is the nip and tuck at the rear to create a spoiler on the trunk lid, which does a great job of communicating the intent of the company's sporty model. Xcar ranks the Continental GT as Britain's best grand tourer, although this video doesn't really explain why in much detail. If you learn about all of the coupe's changes from this clip but still want to know how the vehicle drives, check out Autoblog's First Drive of both the V8 and W12 models for a much more thorough impression.

Xcar asks why the W in the Bentley Continental GT

There aren't a lot of automakers producing V12 engines these days: There's BMW and Mercedes, of course, and the Rolls-Royces and Paganis they power. There's Ferrari, Lamborghini and Aston Martin. But the largest producer of twelve-cylinder engines doesn't make them in a V. That'd be Bentley, and it produces more dozen-piston engines than anyone else, but arranges them in a W configuration. It's a compelling story of innovation, one as interesting as the history of the marque itself. And Xcar tells the tale in its latest video installment, tracing it back to the development of the compact VR6 engine and the autocratic mastermind at the helm of the Volkswagen Group who made the W12 a reality. By this point it would be all too easy to consign the W12 to the dustbin of history as the smaller, more efficient and nearly as powerful V8 has slotted in below to push the W12 to the margins of relevance. But it's still the more refined option, and the more innovative one. Little wonder it's the only type of twelve-cylinder engine (the Aventador's notwithstanding) that the Volkswagen Group still makes.
