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.

Jay Leno chats with Magnus Walker about his 1972 Porsche 911 72STR

Magnus Walker has stopped by the Big Dog Garage again to pay Jay Leno a visit in the latest episode of Jay Leno's Garage. This time, the Porsche builder brought along his 1972 911 72STR 002. Walker calls the machine his best build to date, and the car is a rolling "best of" from Porsches past, rocking some of the more attractive elements pulled from a wide arc of 911 model years. Of course, the machine also wears a few signature Walker touches, including flush-mount turning indicators, a center-hood fuel filler and plenty of louver work.
Unlike some of Walker's other creations, the 72STR 002 is clean enough to lick. Leno seems suitably impressed with the creation, and while apparently isn't typically a fan of Porsche models in general, Walker's tastefully modified 911 has him singing a different tune. You can check out the car in the video below.

2015 Porsche Macan Turbo

I knew it was a softball question, but I asked it anyway. It's pretty standard for automakers to offer up some examples of competitors when they invite the media to drive a new vehicle for the first time. If not stated outright, it's just as standard for some journalist to query about the competitive set as soon as the Q&A begins. I knew full well that Porsche believes it has a valuable new niche to itself with the 2015 Macan (and especially with the Macan Turbo), but I wanted to hear the answer to the competitor cars question anyway.
Porsche CEO Matthias Müller didn't hesitate for a second to respond. With a half-smirk appropriate to an executive that is about to launch the (very probably) most profitable and best-selling product in his brand's lineup he chuckled, "Of course, I could be arrogant and say this car has no competitors..."
Arrogant? Well, the grinning Müller certainly didn't give off a humble vibe as he proceeded to count down a list of German and British utility vehicles from various classes that are clearly behind the pace of the Macan in either looks, luxury, or sporting prowess - Range Rover Sport, BMW X3 and Mercedes-Benz GLK among them.
