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.

VW recalls 1.1M Jetta, Beetle models in US, China over suspension fears

Volkswagen is recalling about 1.1 million vehicles in China and North America in a newly announced campaign affecting the rear suspensions on some models. For the US, the action covers about 442,265 vehicles, including 400,602 examples of its 2011-2013 Jetta and 41,663 units of the 2012-2013 Beetle and Beetle Convertible. According to Reuters, the recall affects a further 126,000 vehicles in Canada and about 581,090 in China, including related market-specific models like the Sagitar.
The problem can occur if the affected models have a collision to the rear or the side-rear of the vehicle. It's then possible for the trailing arms on the torsion-beam rear suspension to be damaged. If the harm isn't noticed, then the part could fracture while driving. Obviously, a broken rear suspension is going to have an adverse effect on handling.
To fix things, VW dealers will inspect the trailing arms on the models, and they will all receive a sheetmetal part that will make a distinctive sound if broken in the future. If already damaged, the entire torsion beam will be replaced. Obviously, this work will be done at no charge to owners.

MotorWeek looks back at the 1986.5 VW Scirocco 16V

It's back to the past with MotorWeek for a video dive into the 1986.5 Volkswagen Scirocco 16V, the coupe that carried the pennant for VW's performance aspirations for 15 years, from 1974 to 1989. This one, the last generation, got the hottest of all by adding a head with four valves per cylinder. The 1.8-liter DOHC engine cranked out "an amazing" 123 horsepower and 120 pound-feet of torque, and made this model the fastest VW to ever be sold in America; it went from 0 to 60 miles per hour in 8.5 seconds, faster than a Porsche 944. To compare vintage apples to modern ones, the New Scirocco with a 123-hp 1.4-liter TSI engine and a manual transmission takes 9.3 seconds. We like MotorWeek's Retro Review series not only for the cars, but for how they also remind us of what we used to find important in cars. The Scirocco here gets upvoted for its throttle response and handling, downvoted for an oddly placed oil pressure gauge and lack of battery voltage meter. We can't remember the last time a voltage meter was mentioned in a review, either its presence or lack. Check out the video above for what the definition of "US hot hatch" used to be.
