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.

The dream of the '90s is alive in Porsche 968 retro review

Only a month after Porsche confirmed that the next-generation Boxster and Cayman will get four-cylinder engines, it is apt that we have a MotorWeek retro review of the 1992 Porsche 968. Porsche hoped the 968 – nee 944 – and its naturally-aspirated, 3.0-liter, four-cylinder would revive sales of its entry-level line, but that didn't happen: going on sale in 1992, 1995 was its last year on the market. This was at a time when a stock 968 coupe cost $39,850, surpassing the out-the-door price of a loaded Chevrolet Corvette. The 968 convertible cost $51,000. That didn't stop MotorWeek's unanimous support of the 968, praising its design, the delivery of its 236 horsepower and 225 pound-feet of torque, and its handling - MotorWeek called it "Pure 90s performance," in spite of some fiddly switchgear and a noisy, firm ride. You can watch the review above. We have a feeling Porsche's four-cylinder fortunes will go much better this time around.

Used Porsche 911 Rs are selling for nearly $1.3 million

Some cars are just born to be collector's items. Prices of Porsches of all years and styles have started to rise in recent years, particularly air-cooled 911s, but the 911 R seems to take the cake. Used ones are trading hands for almost $1.3 million on the used car market. For a car that sold new for $185,950, that's quite a steep markup. In fact, at seven times the original MSRP, high-end car finance company Magnitude Finance told Motoring Research that it may be an appreciation record. Porsche only built 991 911 Rs. The number is a reference to the current 991 chassis code for this generation of the 911. When it was announced, it was heralded as the purists 911: a lightweight special equipped with a manual transmission and backed by the 4.0 liter flat-six from the GT3 RS. It's hard to say if this is a trend or simply an anomaly. The car hasn't been on sale for long, so few have publicly changed hands. Hopefully the next 911 GT3 will satiate those who desire a driver focused 911 experience at a slightly more reasonable price point. Related Video:
