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.

What hardcore 911 is Porsche working on now?

Porsche has been spotted testing a new hardcore version of the latest 911. The prototype appears to blend the best elements from the recently facelifted 991.2 with those of the outgoing GT3 RS, which both follows logically and bodes well for the German automaker's latest track-focused performance machine. That means new lighting and other touches, but also more ventilation than a toxic chemicals facility. The bigger question, however, is what engine Porsche is hanging off the back. If history teaches us anything, we could be looking at one of several possibilities. For one, this could be a prototype for the updated 911 GT3 RS, carrying a modified version of the existing model's 4.0-liter flat-six, still naturally aspirated, but maybe with a few extra horses kicked in over the outgoing version's 500 hp. For another, it could follow in the footsteps of the previous limited-edition GT3 RS 4.0, but since the existing model already boasts that displacement, this one could go a step further at 4.2 liters. But then it might not be a GT3 at all: we could be looking at the rebirth of the GT2, the primary difference between the two being the absence or presence of turbochargers. Porsche hasn't done a forced-induction GT model since the GT2 RS of 2010, and that was essentially a 911 Turbo sans the all-wheel drive and any shred of sanity. Whatever is lurking under all that aggressive bodywork, we're looking forward to finding out. And we get the distinct feeling that it won't disappoint.

Autoblog Minute: UAW and FCA avoid strike, Clarkson teases new show

FCA avoids a worker strike, a former Top Gear host teases us with a picture from Amazon's new car show, and Toyota predicts autonomous cars by 2020. Autoblog senior editor Greg Migliore reports on this edition of Autoblog Minute Weekly Recap. Show full video transcript text [00:00:00] FCA avoids a worker strike, a former Top Gear host teases us with a picture from Amazon's new car show, and Toyota predicts autonomous cars by 2020. I'm senior editor Greg Migliore and this is your Autoblog Minute Weekly Recap. A UAW strike of FCA was avoided thanks to a zero-hour tentative agreement reached this week. Worker concerns that were renegotiated in the new [00:00:30] deal include adjustments to the two-tier wage scale, health care costs, and production outsourcing. Now check-in with Autoblog as we update our reports on this evolving story. Shooting began on Amazon Prime's new automotive show starring the former Top Gear crew. That's Jeremy Clarkson, Richard Hammond, and James May. Now Clarkson threw out a tweet from day one of filming on location at Algarve Motor Park in Portugal. The picture features the show's [00:01:00] three stars and crew posing with the holy trinity of hyper cars. That's a McLaren P1, a Ferrari LaFerrari, and a Porsche 918 Spyder. This Prime show is being called Gear Knobs though the name is unofficial. Now if a tweet is any indication of what we can expect, who cares what it's called this is gonna be awesome. (Eds Note: Clarkson tweeted Friday that the show will not be called Gear Knobs.) Toyota predicts drivers could be obsolete on highways as early as 2020, with technology dubbed the Toyota Highway Teammate or THT. Toyota is using a modified [00:01:30] Lexus GS to show what this is capable of. THT is already able to create a driverless freeway car that's capable of changing lanes, making passes and taking curves. Plus, it can keep safe distances from other vehicles. Toyota is currently testing this on Tokyo's Shuto Expressway. Those are the highlights from the week that was. Be sure to check out my full recap this Saturday. And I'll have some added insight on the BMW M4 GTS. For Autoblog, I'm Greg Migliore. [00:02:00] Show Logo Autoblog Minute is a short-form video news series reporting on all things automotive.
