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.

Porsche Panamera wagon may appear next year

Following the second-generation Panamera's debut this past summer, it seems Porsche is planning the unveiling of a more practical wagon version next year. Based on previous information, this seems like a strong possibility. Automotive News spoke with anonymous sources at Porsche who said the car will probably be shown at the 2017 Geneva show. This would fall in line with a report that slated the wagon for a 2018 release, which would make sense to reveal the car in 2017. We've also seen a Panamera prototype with a lengthened roof testing at the Nurburgring, indicating that Porsche is working on one that could be close to production-ready. In addition, Porsche's North American CEO confirmed the US will get a Panamera wagon if it reaches production. If it reaches production, the Panamera will be almost without competition in the US. While it would compete with the Mercedes-Benz CLS Shooting Brake, as Automotive News points out, and the Audi RS 6 Avant in Europe, the US really only has one midsize, luxury wagon left on the market it would face-off with. That would be the Mercedes-Benz E-Class wagon. The current generation is only available as the E400, but we expect an AMG E63 model to be official soon. While an impressive vehicle in and of itself, the E-Class still has traditional, upright wagon proportions instead of the sleek, raked shape of the possible Panamera wagon. The E400's 329-horsepower twin-turbo V6 is also a perfectly competent engine, but the standard Panamera packs a 440-horsepower V6, and it only gets more powerful as you move up to the hybrid with 462 and the V8 with 550. All are engines that would likely be available on the wagon. UPDATE: A previous version of this story incorrectly stated that the E-Class wagon was rear wheel drive. It actually comes with all wheel drive standard. The text has been altered for accuracy. Related Video:
