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.

Which is quicker in the standing mile, a Subaru WRX STI or a Porsche Cayman?

The 2015 Subaru WRX STI and 2014 Porsche Cayman are both saddled with unfair reputations. The STI with its huge wing and gold wheels has the title of the ultimate boy-racer. On the other hand, Porsche brand snobs look down on he base Cayman as just a wannabe 911. In reality, they are both pretty fantastic performance cars. But what would happen if the two of them lined up at a stoplight, and maybe the guy in the suit in the Cayman started throwing some revs at the young man in the STI? Automobile decided to find out in a recent video pitting the two stereotyped hot rods against each other in a standing-mile drag race.
In terms of raw numbers, they are surprisingly close. Both use flat engines and six-speed manual transmissions here, but the Subaru has more power and torque. However, the Porsche makes up for it with 300 pounds less weight. Neither should have a problem with traction either thanks to the STI's sophisticated all-wheel-drive setup, and the Cayman's mid-engine, rear-wheel-drive layout.
The comparable specs certainly show themselves in the real world for the race. We're not going to give away the winner here because it's too exciting, but let's just say the finish is very, very close. Scroll down to watch both of them shrug off their stereotypes and show off their real performance.

Porsche Macan Turbo vs Cayman GTS in track battle

"Well this is stupid." On the surface, that was our reaction to this video, as well. Why would you compare the hottest Porsche Cayman with a crossover of any kind, even if it is the 400-horsepower Macan Turbo?
We're guessing because it'd be bloody good fun, as evidenced Auto Express's latest track battle. To be fair, there is some interesting stuff here. The two do have a similar starting price, separated by less than $3,000 here in the US market. And, factoring in the Macan's hefty horsepower and torque advantages - 60 horsepower and 126 pound-feet - does make for a slightly interesting comparison.
We won't spoil the verdict, so check out the full video from Auto Express, and then let us know what you think in Comments.
