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.

Preparing for Le Mans 2014 Porsche remembers 1971 and the 917 [w/video]

Porsche has given us another look back at its successes at the 24 Hours of Le Mans. This time it's 1971, the year that its 917 set records that haven't all been eclipsed. It's 45-kilogram magnesium tube frame was the lightest, Jackie Oliver set the fastest in-race lap with a time that still stands, and winning drivers Helmut Marko - the same Helmut Marko currently with Infiniti Red Bull Racing - and Gilles Lethem did so many laps that their distance wasn't exceeded until the Audi R15 TDI did it in 2010.
1971 was also the year of the "Pink Pig." With bodywork created by a French aerodynamics firm, the wider, rounder 917 earned the porcine moniker so Porsche painted it pink and labeled it with the cuts you'd get from a pig. Sponsor Martini was so miffed they demanded all Martini branding be removed. No one can remove the thousands of photographs taken of the car ever since. Enjoy that and more in the video below.

Jaguar F-Type squares off against Porsche 911, Aston V8 Vantage with Chris Harris

Chris Harris is back on the job, taking on really really difficult car questions like: Which enormously sexy and good-to-drive, high-performance convertible is the top of the heap? As one of the hottest cars in the luxury space right now, the Jaguar F-Type S is, of course, in on the action. Competition comes in the form of the Aston Martin V8 Vantage Roadster and the Porsche 911 Carrera S Cabriolet. Sun-loving CEOs who despise test-driving need look no further.
Scroll on below for a fully featured (with a running time of more than 20 minutes) comparison video. Harris does his best to entertain - in a typically nitpicky and made-up-British-words fashion - and the moving pictures are lovely to look at. Kick back, pour a pint and get your weekend started off right.
