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 911 Carrera 4S named Motor Trend Best Driver's Car [w/video]

Motor Trend has named the 2013 Porsche 911 Carrera 4S its best driver's car for 2013. The annual
competition for the title included some of the best performance cars that have gone on sale in the past year. The new C4S follows the 2012 Best Driver's Car award winner, a two-wheel-drive Carrera S.
Determining the winner of the coveted title isn't easy. Each vehicle is pushed through Motor Trend's normal battery of instrumented tests. Editors then spend time with each car over a 500-mile tour of mixed conditions before a final batch of testing at Mazda Raceway Laguna Seca, with pro racer Randy Pobst at the wheel.

Will Roegge makes 4K art of Jeff Zwart's 911 build and run up Pikes Peak

Will Roegge has turned his camera on Jeff Zwart and provided another gem, this time documenting Zwart's run up Pikes Peak and BBI Autosport. Bertim Besha dropped out of high school, then worked his way up to founding his own shop, BBI, that gathers a crew of tuners who are just as fastidious about their work as the customers are about their cars.
They prepped the 991-series Porsche 911 GT3 Cup Turbo, the product of combining a 911 GT2 that was the most powerful car Zwart drove up the mountain with a GT3 Cup that Zwart thought had the best handling. Two TiAL turbos and a lot of fettling make for a 3.8-liter flat-six with 700 horsepower, 700 pound-feet of torque and a 7,800-rpm redline. Zwart drove it to a heartbreaking second place this year, finishing less than 1.2 seconds behind the Time Attack 1 class winner when his car suffered its first mechanical issue of the week.
The first video below covers Besha, BBI and the build, the second is Zwart's run. As if the visuals weren't enough, sit back and enjoy the shrieking of the "Hill Climb Special," which is what the constellation Sirius would sound like if it could bark.
