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.

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.

Ex-Fiat exec: VW diesel scandal will hurt plug-in hybrids

It doesn't sound right at first blush, but former Fiat executive and noted diesel-powertrain expert Rinaldo Rinolfi thinks that plug-in hybrid sales may be more impacted by the VW diesel-emissions scandal than diesel sales. Rinolfi, who worked for Fiat for 40 years, told Automotive News Europe, said that the Euro 6 emissions rules that went into effect in 2015 have already increased diesel-engine production costs enough to raise prices and ultimately flatten demand. By the end of the decade, diesel-vehicle sales will settle in at a 40-percent market share of new European vehicles, and that was going to happen with or without the scandal. "Every carmaker has found ways to achieve fuel consumption and emissions results that have progressively diverged from the real driving conditions." - Rinaldo Rinolfi Makers of plug-in hybrids have more to lose, though, because every PHEV maker has figured out a way to keep emissions figures artificially low, Rinolfi said. Under New European Driving Cycle (NEDC) standards, PHEVs can be tested part of the time with the electric motor in action, meaning emissions get driven down to 30 percent to 40 percent less than real-world figures. With the VW scandal pushing regulators to use real-world figures, those PHEV emissions numbers are expected to rise substantially. To a lesser extent, hybrid emissions figures are also tested as artificially low. "Over the years, even without defeat devices, every carmaker has found ways to achieve fuel consumption and emissions results that have progressively diverged from the real driving conditions the customer experiences," Rinolfi said in the Automotive News Europe interview. Rinolfi is a little sunnier about compressed natural gas (CNG) vehicles, estimating that CNG emissions are as much as 25 percent lower compared to conventional vehicles. As for battery-electrics, he's not so optimistic, estimating that there needs to be at least a tenfold improvement in energy efficiency for EVs to be truly competitive with conventional vehicles. "I've been waiting for a true breakthrough for the past 25 years, but I've not seen it yet," Rinolfi said about EVs in the Automotive News Europe interview.
