The 2017 Porsche 911 RSR goes mid-engine, purists be damned

Porsche unveiled its World Endurance Championship and IMSA WeatherTech Championship competitor with the 2017 911 RSR. And this 911 is different from the rest, as the 4.0-liter flat-six engine powering this beast is in front of the rear axle, not behind it. That's right, this 24 Hours of Le Mans competitor ditches the iconic rear-engine layout. Porsche isn't talking specifics on how exactly things are arranged back there. The engine is new, now based on the 991 911's block instead of the previous Mezger motor that's been used for years. The transmission design is new as well – it would have to be to accommodate the new location relative to the engine. The racecar has been engineered to meet the LM-GTE class, where it will go up against other mid-engine cars like the Ford GT and Ferrari 488 GTE. Moving the engine to the middle has given Porsche the ability to fit the 911 RSR with massive bits of aero, like the humongous rear diffuser that looks like it would be more at home on a machine of war. The only thing that can compete with the diffuser for size is the top-mounted rear wing, which shares a similar design to the one found on the 919 Hybrid. Going back to the engine, the direct-injected boxer motor, depending on the size of the restrictor, generates as much as 510 horsepower and sends all of its fury to the rear wheels. The engine is paired to a six-speed sequential gearbox, which drivers can employ through paddles on the steering wheel. The new engine doesn't have a lot of weight to push around as the 911 RSR, as required by regulations, weighs 2,740 pounds. Speaking of weight, the engine layout isn't the only change for the 911 RSR. For 2017, the car ditches its steel body for one that's made out of carbon fiber. The body attaches to the chassis via quick-release fasteners, making the vehicle easier to service as exterior elements can be removed with minimal effort. The racecar also gets a radar-based collision system – aptly named the "Collision Avoid System" – which is meant to limit the 911 RSR's encounters with faster LMP prototypes. Only time will tell if the new layout and aerodynamic components help the 911 RSR beat its competition. But there will be plenty of opportunities to see the racecar in action as Porsche plans to run the 911 RSR in 19 races during the 2017 season, the first of which will take place at the IMSA opener on January 28th at Daytona, where the racecar will make its track day debut.

Audi, Porsche ensnared in new Volkswagen cheating allegations

The scope of the Volkswagen emissions cheating scandal that has enveloped the global automaker for the past six weeks widened Monday. Now, some of the automaker's premium brands are further ensnared in the mess. Officials with the Environmental Protection Agency issued a second notice of violations Monday, accusing Volkswagen of violating the Clean Air Act by using defeat devices that circumvent emissions testing on diesel versions of certain vehicles equipped with 3.0-liter engines. Roughly 10,000 vehicles in the United States contain the illegal software, the EPA alleges. That's a far smaller number than the 482,000 vehicles affected by the first instances of cheating, which Volkswagen confessed to in September. But this latest violation alleges the cheating occurred broadly through the Volkswagen empire and includes vehicles from the Porsche and Audi brands. Audi had one model, the A3, involved in the first round of announced violations. But the brand, which has enjoyed skyrocketing sales in the US in recent years, is more extensively involved in violations announced Monday. The 2016 Audi A6 Quattro, A7 Quattro, A8, A8L and Q5 are among the cars which contain the illegal software, which permits the cars to emit nitrogen oxide at up to nine times the allowable thresholds set in the Clean Air Act, according to the EPA. The 2015 Porsche Cayenne and '14 Volkswagen Toureg SUV are also affected. "There is clear evidence of additional violations and it's important to put Volkswagen on notice and to inform the public." - Janet McCabe. "Audi, which has been on a roll in terms of sales, reputation and image of late, now is being drawn deeper into the quagmire," said Michelle Krebs, senior analyst for Autotrader. "Previously, only the low-volume A3 was under scrutiny, but now Audi's core models are under fire." Audi officials did not respond to a request for comment Monday. In a written statement issued late Monday afternoon, a Porsche spokesperson said, "We are surprised to learn this information. Until this notice, all our information was that the Porsche Cayenne Diesel is fully compliant." Porsche said it would cooperate with authorities.

Porsche 911 GT2 RS vs. Mercedes SLS AMG Black in battle of who can shred more rubber

We might be looking at the end of an era in European performance models. Mercedes-Benz is doing away with the SLS in favor of a rumored smaller and cheaper SLC, and Porsche has said that a new 911 GT2 isn't necessarily a sure thing, which means another 911 GT2 RS is even farther away. In its latest video, Evo's Jethro Bovingdon pits the ultimate versions of these German sports coupes against each other and finds two of the fastest cars the magazine has ever lapped around its track.
In one corner, there is the Mercedes SLS AMG Black Series that sits as the pinnacle of the company's halo model. It relies on the classic setup of a V8 mounted in front powering the rear wheels. On the other side, there is the 911 GT2 RS with a turbocharged flat-six mounted at the back, spinning the rear wheels. It was conceived to be Porsche's ultimate expression of a turbocharged 911, and while it's a few years old, Bovingdon shows that it's up to the task of racing a more modern rival.
Both of these rear-wheel-drive monsters are more than capable of some fantastically smoky power-slides, but they also show how great the last generation of sports cars was. Scroll down to check out the video.
