2014 Porsche 911 Turbo S

A Wicked-Fast Street Legal Multi-Tool
Walter Röhrl was carving up the circuit in the Porsche 911 Turbo S like a skilled Jedi Master - and I was sitting next to him, mesmerized by the breathtaking show. I had strapped myself securely into the front passenger bucket of the all-new coupe less than a minute earlier, expecting nothing more than a few quick laps around a track at the hands of another celebrated race driver. Been there, done that. Many times, actually.
Yet this was different. Röhrl was not only calculated and methodical in his approach, but his rally-tuned cerebrum appeared to be actively reading available grip levels while effortlessly tossing the all-wheel-drive Porsche into each corner at gut-wrenching speeds. His hands were moving rapidly, sending tiny steering corrections to the front tires, and he was using every inch of the track to extract more speed. We launched over a curb, dropped a wheel in the dirt and then drifted around a wide off-camber turn. His human precision and focus was astounding, and the performance he was extracting from the machine was just short of breathtaking.

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.

Ring Taxi BMW M3 chases an Aventador SV and Cayman GT4

On paper, a BMW M3 that's loaded with three passengers probably shouldn't have a chance at keeping up around a track with a Porsche Cayman GT4 and a Lamborghini Aventador LP 750-4 Superveloce. In the real world, driver skill and track knowledge can make all the difference, though. And when the M3 is a Nurburgring Taxi with a driver that knows the course incredibly well, we end up getting a fantastic lap like this one. The 'Ring Taxi driver starts by teasing his passengers that they'll see whether the Lambo is fast. Before the two of them get on track, the GT4 cuts in to join the party. What follows is a fascinating lap of the Nordschleife. It's impressive how the BMW driver's skill allows him to keep up with the two other cars and blow past tons of other traffic. During faster sections, the Porsche and Aventador start to pull away, but as soon as the course gets curvy again, the M3 is right back in the action. As the group pulls back into the parking lot, even the Ring Taxi driver sounds impressed with his performance. See the impressive show in the video above. Related Video:
