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.

Watch the incredibly complicated operation of Porsche's new targa roof

Despite Porsche having claimed the name, targa tops are nothing new. In addition to the semi-roofless version of the 911, plenty of cars in the past have used removable roof panels - the new Corvette Stingray has one (as have prior generations), and this type of open-air experience has been available on past vehicles like the Pontiac Solstice Coupe and Honda Civic del Sol.
But when Porsche took the top off its brand new 911 Targa here at the Detroit Auto Show, it was indeed cause for pause. Simply put, this is one of the most complicated and intricate electronic roof panel removal techniques we've ever seen, save perhaps, for the setup found on the Japanese-market Civic del Sol from the 1990s.
We won't spoil the video for you, but basically, rather than just the roof panel coming off, the entire rear glass area lifts away the body in order for the small section over the passenger compartment to slide back. This has to be incredibly expensive to repair once it inevitably breaks. And we highly doubt you'll be able to operate this mechanism at any speed.

2017 Porsche Panamera revealed: It's finally pretty

Things are looking up for the Porsche Panamera. Dynamically, it's always been good – fast, comfortable, and much more spacious than something like a 911 – but the general consensus is that the first-gen Panamera's styling was, shall we say, less successful. All that changes for the second-generation car. Despite being longer, wider, and taller than before, it's much more attractive, with a lower roofline that sweeps back toward the rear haunches with a pleasing arc. There's a clear styling link to Porsche's mainstay, the 911. The new Panamera's body is made mostly from aluminum, minus some high-strength steel and the optional large, panoramic roof overhead. LED lighting elements front and rear look suitably up-to-date, especially the interconnected design of the taillights. Wheels range from 19 inches to 21, with 20s standard on the Turbo. Porsche isn't just recalling its current sports car with the new Panamera. The central tachometer is designed to evoke the one in the 1955 356 A, more colloquially known as the Speedster. Beside that one analog throwback, however, the latest Panamera is fully modern and technologically advanced. Two seven-inch screens flank the tach, and the Porsche Advanced Cockpit includes a 12.3-inch tablet-like touchscreen in front of the driver. Apple CarPlay is available, but there's no mention of Android Auto. A new thermal imaging camera makes it easier to see in the dark. A completely new range of engines powers the second-gen Panamera, starting with a twin-turbo 2.9-liter V6 that puts out 440 horsepower and 405 pound-feet of torque. In the Panamera 4S, that's enough to launch the saloon to 60 in 4.4 seconds (4.2 with the optional Sport Chrono Package) and to hit a top speed of 180 miles per hour. The Panamera Turbo boasts a 4.0-liter, twin-turbo V8 with 550 hp and 567 lb-ft. The 0–60 run takes just 3.6 seconds (3.4 with Sport Chrono) and the top speed is 190 mph. Both the 4S and the Turbo come with standard all-wheel drive and an eight-speed PDK dual-clutch automatic transmission. Much of the chassis tech from the last Panamera is carried over, including Porsche Active Suspension Management, Porsche Torque Vectoring Plus, and active roll stabilization. The available active air suspension has been updated with a three-chamber design. The 2017 model adds rear-wheel steering as an option, borrowed from the 911 line.
