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.

Porsche Cayman S and Caterham 7 go head to head on the drag strip

We recently saw the standard Porsche Cayman go up against a Subaru WRX STI in a one-mile drag race with surprising results. Apparently, Evo had a similar idea of evaluating the Cayman's quickness. However, it opted for the more powerful S model and chose a flyweight Caterham Roadsport 140 as the challenger. Will the results of this battle be as close at the end of the kilometer-long (0.62-mile) drag?
Neither of these are cars you'd usually associate with drag racing, but they are nearly evenly matched. Evo selected them based on power-to-weight ratio, with the Caterham offering a scant 140 horsepower in a lithe 1,213-pound package. The Porsche is a quite svelte 2,910 pounds but has 325 hp to haul it around.
Of course, power-to-weight ratio isn't everything. There are a ton of other variables like aerodynamics and gearing that play a huge role, as well. Can the little Caterham's weight advantage overcome the better aero and additional power of the Porsche? Scroll down watch the video and find out.
