Porsche finally moving ahead with flat four engine

When Porsche released the first Boxster in 1996 and the first Cayman in 2005, the idea was to create an entry-level model for the German automaker's sports car range. The latest iterations of both closely related models, however, have begun to encroach dangerously on the 911's territory, particularly in their newest GTS specifications. That could be about to change, however, with the introduction of a four-cylinder engine for the compact mid-engined coupe and roadster.
According to Automotive News, Porsche is finally preparing to launch a new boxer four engine in the Boxster and Cayman, following years of speculation. The engine would be based on the same architecture as the company's famous flat six, but with two fewer cylinders to cut weight. Don't expect it to cut much in the way of performance, however: Porsche chief Matthias Muller indicates that the new engine could produce as much as 395 horsepower - significantly more than even the 340hp flat six in the Cayman GTS, suggesting that the engine could even find its way into the 911 as well.
It's no more clear which markets would get the four-cylinder engine, either. But wherever it is offered and in whichever form, it wouldn't be the first time we'd see a Porsche with a four-pot engine. Not by a long shot. Both the classic 912 and 356 were powered by boxer fours, as was the 914 - not to mention the 718 pictured above and the iconic 550 Spyder. The front-engined 924, 944 and 968 packed inline-four engines, but the last of those were discontinued in the 1990s. The prospect of a four-cylinder Boxster/Cayman has been rumored for many years now, most recently joined by the possibility of a four-pot Macan as well.

Chris Harris hits the track in the Porsche 911 GT3 RS

One of the wonderful things about Chris Harris on Cars is the enthusiasm that the host brings to the screen. Granted, it would be hard not to enjoy a day driving around in a supercar that you don't own. Still, Harris brings a sense that he knows how rare these opportunities are and relishes them. In his latest look at the two sides of the latest Porsche 911 GT3 RS, you can tell this guy is having a lot of fun. The GT3 RS is a 500-horsepower, track-focused weapon, but it's expected to drive to and away from the circuit after a day of laps. Therefore, Harris decides to evaluate the attributes of this Porsche in both environments. On the road, he sweeps an orange example over some beautifully, undulating German backroads but keeps things rather tidy. However, in the latter half of the video, he arrives at the Weissach test track for a go in a purple RS. There, he really lets the rear hang out.

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.
