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.

Petrolicious details why the Porsche 911 is something special

The Porsche 911 is a special car, if for no other reasons than it's been continuously produced since 1964, with nearly every generation regarded as being at or near the top of its class. But why the rear-engined icon has done so well among enthusiasts and regular drivers alike can't always be explained easily. To truly understand the 911, you have to experience the whole package, and that means driving one.
While just about every publication has raved about the Porsche, commercial director, race driver, photographer and 911 owner Jeff Zwart explains to Petrolicious why he was drawn to the legend as a young child, and why he still loves them today.
Zwart's professional and personal life are inextricably linked to the 911, and hearing him talk about the car and its history makes for fascinating viewing. Watch the video below to hear Zwart's story and see him drive a couple examples from his collection: an early 911 and the 964-generation Carrera 4 he won Pikes Peak with for the first time - a car that happens to be equipped with the 959 Paris-Dakar's fascinating torque-split transmission. Enjoy!

Porsche drivers escape this horrific VIR crash unscathed

There is no doubting the fact that it takes nerves of steel to be a racecar driver, but the same can also be said for motorsports photographers. Case in point: The American Le Mans Series Oak Tree Grand Prix at the Virginia International Raceway where two Porsche 911 racecars crash hard into the tire barrier, but the dedicated cameraman stays with the shot - diving away only at the last second just as the battered No. 31 car (shown above) comes to rest atop the tire barriers just feet from where he was standing.
The crash occurred when the two Porsches charged hard into a corner. Judging by the video, the white No. 48 car appears to not see the orange No. 31 and the two cars make contact, skidding off track hitting the tire barriers at a high rate of speed. Both drivers walked away from the frightening crash, but the video - posted below - shows just how bad things could have been. Hopefully the close call will serve as a lesson for the woman standing in the track marshal's post who has her back to the racing as the two cars barrel directly toward her.
