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.

Juan Pablo Montoya tests Porsche 919 Hybrid in Bahrain

Sealing the FIA World Endurance Championship wasn't the only thing that Porsche did this past weekend in Bahrain. Alongside its rivals from Audi and Toyota, the German outfit also participated in a test session for potential new drivers, including Juan Pablo Montoya. Driving the Le Mans- and championship-winning Porsche 919 Hybrid at the Bahrain International Circuit this weekend, Montoya set the fastest time of the day. His "qualifying" lap was clocked at 1:40.86, barely more than a second behind the 1:39.67 lap that earned Timo Bernhard pole position in the previous day's race – and a second faster than the fastest lap set in the race by Neel Jani in another 919 Hybrid. That's a mighty impressive feat for a driver relatively unaccustomed to driving a modern hybrid LMP1. Racing fans will know Montoya as a multi-talented driver. The Colombian has competed successfully in Formula One, Indy, NASCAR, and sports prototypes, winning races in all disciplines. Aside from the International Formula 3000 title, three outright victories in the 24 Hours of Daytona, and a handful of NASCAR street-course races, Montoya can count among his many achievements the CART title, two Indianapolis 500 wins, and the checkered flag at the Monaco Grand Prix (along with six other F1 races). Those victories have brought JP among the closest to winning the Triple Crown of motorsports of any driver in racing history, and he's still competing. For those unfamiliar, the Triple Crown is an unofficial measure to gauge the diverse talents of professional racing drivers in three disciplines: Indy, F1, and Le Mans. To win, a driver has to win the Indianapolis 500, the 24 Hours of Le Mans, and either the Monaco Grand Prix or the Formula One World Championship. Graham Hill is the only driver in history to have swept all the categories, but others have come close. The list of near-winners includes Tazio Nuvolari, Mike Hawthrown, Phil Hill, AJ Foyt, Bruce McLaren, Jim Clark, Mario Andretti, and Emerson Fittipaldi. The only contenders still active are Montoya and Jacques Villeneuve, who won at Indy in '95, the F1 championship in '97, and came second at Le Mans in 2008. Villenueve could still steal the crown if he gets another shot at Le Mans, but the more likely scenario would be to see Montoya rise to the throne. Especially if this test session is any indication. Also driving the Porsche was in the rookie test session was Mitch Evans, a former GP3 champion and GP2 race winner from New Zealand.

Super Bowl car commercials: Follow along as we riff on them live

Join Autoblog editors Sunday starting around 6:30 p.m. ET as we react to all of the car commercials during the game. We know Hummer, Porsche, Hyundai and others will have splashy ads, and naturally, there's usually a few surprises. Whether you're a Chiefs or 49ers fan — or don't care about football — the commercials are always a highlight. And for us, the car spots are the most intriguing. Weigh in with your own thoughts in the comments section. Let's kick off.   FIRST QUARTER Editor-in-Chief Greg Migliore liveblogs the first quarter. F9 We'll count this as a car commercial. The latest edition of the Fast & Furious looks like it well, will have cars. We'll punt on further comment. PORSCHE I like it. Creative. Sort of a Night at the Museum feel. The guards stage a theft and then a car chase. The Taycan looked good. Get fired up — the future for Porsche is electric. The spot is meant to illustrate how fun that can be. I don't need any convincing.    SECOND QUARTER Associate Editor Byron Hurd is liveblogging the second quarter.  HYUNDAI Hyundai checked in super early with their Sonata "Smaht Pahk" commercial, which manages to score points for being both cute and clever while also being a fairly good commercial in a vacuum. We saw it last week, so there were no surprises here, but we enjoyed it nonetheless.  Fun note: If you go to the Sonata landing page on Hyundai's web site, you can choose "plain old English" or "the Boston way" for your language; the latter will translate the page. Enjoy.  FORD Hi ho, West Coast Editor James Riswick here. Apparently, the guys in Detroit didn't get the Mustang Mach E ad featuring Idris Elba and a whole boat load of awesome old Mustangs. Pretty sure it's bound to be viewed the exact same way as the car itself: traditionalists will be aghast, while non-car people will be intrigued by a new, all-electric, crossover version of one of the few cars they've heard of.  GENESIS They're coming more rapidly now. Genesis gets some love thanks to Chrissy Teigen and John Legend; this was another known quantity, but Hyundai's luxury brand managed another solid entry here thanks to its choice of stars. Teigen and Legend got the chance to throw back to the latter's "Sexiest Man Alive" honors, which Teigen often teases him for. Another solid all-around spot.  GMC/HUMMER Are there just no surprises left? Don't tell me; I know the answer. LeBron James fronts the revived Hummer, which will be an EV sold as a GMC.
