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 918 Spyder burns to ground in gas station conflagration

There's one fewer Porsche 918 Spyder zipping along the roads of Toronto, Canada, today. A fire at a gas station over the weekend claimed one of the hybrid supercars in a massive blaze, and a portion of the inferno was caught on video.
According to our partners to the North at Autoblog Canada, the cause of the fire hasn't been officially confirmed yet, but witnesses reportedly claimed gasoline somehow came into contact with the hot exhaust outlets that exit out of the top of the supercar's engine bay. This was just one of two 918s believed to be in the Toronto area.
Other than a possible broken heart from the owner, the fire reportedly caused no injuries, and only the Porsche and gas pump appeared to sustain serious damage. Warning, the video of the conflagration does contain some explicit language.

Is Porsche planning a GT5?

A trademark application filed in Europe suggests Porsche could be planning a GT5 model to slot at the bottom of its track-focused sports car lineup. The German automaker's GT skunkworks division in Weissach earned its reputation with enthusiasts producing the GT3 and GT3 RS versions of the 911, and previously offered GT2 and even GT1 models as well (although the latter was a limited homologation special). It recently extended itself slightly downmarket with the launch of the Cayman GT4, but this trademark application – already reportedly accepted in Germany and currently being reviewed by the European office – suggests an even more accessible model could be on its way, Autocar reports. Just what form a GT5 would take, however, remains a mystery. The numerical progression would suggest that Porsche is planning a hardcore version of an even smaller sports car, if such a project ever got off the ground to slot in below the Boxster and Cayman. Given that the 911 has bred both GT2 and GT3 versions, Weissach could alternatively be planning an additional GT version of the Cayman, or planning a hardcore version of the Boxster. The prospect of a GT5 version of the Macan, Cayenne, or Panamera seems unlikely as the alphanumeric designation has never been applied to anything other than a two-door coupe, but then we never really know what the future will bring: Before 2002 Porsche had never done anything with more than two doors altogether. These designations are typically borrowed from their corresponding racing class, and of course there is no GT5 category. But then most of these racing classes have been amalgamated into GT3 anyway, unless Porsche is planning on using the name for its own entry-level spec racing series. But at this point we're just spitballing. It's just as likely that the company has simply filed the trademark application to keep its options open for the future. Related Video:
