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 Cayman S and Caterham 7 go head to head on the drag strip

We recently saw the standard Porsche Cayman go up against a Subaru WRX STI in a one-mile drag race with surprising results. Apparently, Evo had a similar idea of evaluating the Cayman's quickness. However, it opted for the more powerful S model and chose a flyweight Caterham Roadsport 140 as the challenger. Will the results of this battle be as close at the end of the kilometer-long (0.62-mile) drag?
Neither of these are cars you'd usually associate with drag racing, but they are nearly evenly matched. Evo selected them based on power-to-weight ratio, with the Caterham offering a scant 140 horsepower in a lithe 1,213-pound package. The Porsche is a quite svelte 2,910 pounds but has 325 hp to haul it around.
Of course, power-to-weight ratio isn't everything. There are a ton of other variables like aerodynamics and gearing that play a huge role, as well. Can the little Caterham's weight advantage overcome the better aero and additional power of the Porsche? Scroll down watch the video and find out.

Porsche digitally dissects its 918 Spyder for your viewing pleasure

At this point, you'd think we'd know all there is to know about the 2015 Porsche 918 Spyder - except what it's like to drive - but Porsche has released a new video giving us a more in-depth look at its new plug-in hypercar all the same. The animated video gives us numerous cutaway looks at the 918 Spyder while giving a visual demonstration of the car's four hybrid driving modes.
Though nowhere near as exciting as watching the 918 blast around the Nürburgring in record time, this new video is nonetheless both interesting and informative. Scroll down to watch the video yourself, and be sure to check out our live gallery of the production version of the car along with a stock gallery.
