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.

Mini to offer a double-clutch transmission, but not in U.S.

Mini has padded next year's option sheet with a seven-speed dual-clutch transmission, so long as you're not buying in America. Available for the three-door, five-door, and convertible Mini models using "selected engine types," the DCT will provide a third transmission option after the standard six-speed manual and six-speed Steptronic automatic. Minis fitted the twin-clutch will be known by the meaty new gearshift lever that, BMW style, returns to its central position after the car's put into gear. A button at the top of the lever activates Park. Sensibly, you push the lever forward to downshift, and pull it back to upshift. When a buyer springs for navigation and the DCT, the transmission taps into map routing data and camera images to hone shift programming; the gearbox will downshift early when approaching a turn, or read a series of bends to know when to shift and when to hold steady. Fitted with a crawl function for ease of use in stop-and-go traffic, the DCT additionally supports stop/start, and coasting in Mid and Green driving modes for those times the driver takes his foot off the accelerator. For the time being, though, we're not invited to the party. Mini USA Communications Manager Mariella Kapsaskis told Motor1 that manufacturing the wet-clutch, dual-mass flywheel DCT "takes up lots of capacity." Which is the automaker equivalent of being told, "We're just not that into you right now." We expect that would change at some point; however, some of Mini's most sporting U.S. competitors also don't offer DCTs, so who knows.

Mini Superleggera gets the green light

With the fairly lackluster designs coming out of Mini recently, leave it to a group from outside the company to get things right. The minds behind the Berlinetta Lusso and Disco Volante at Touring Superleggera did just that with the retro-inspired Mini Superleggera Vision Concept from last year's Villa d'Este Concours d'Elegance. Now, according to Car in the UK, the droptop has a green light for production from the BMW board and could arrive in showrooms by 2018. The concept stole our hearts with its rounded shape, rear fin and Union-Jack-shaped taillights. Inside, the interior went for extreme minimalism with an aluminum dashboard that positioned just a simple tachometer and thin steering wheel in front of the driver. The production version reportedly rides on the third-gen Mini platform but retains all of the concept's major styling elements. In place of the electric motor, expect the current engine offerings with a 1.5-liter three-cylinder and a 2.0-liter four-cylinder available under the hood. Patent documents might provide an even better hint at what to expect. They also show the design not changing much, other than the lights no longer in the grille, a framed windshield and slightly smaller fin. The Union Jack taillights remain, though. Peter Schwarzenbauer, BMW Group member in charge of Mini, asserted the company was testing the waters for production shortly after the Superleggera's debut. At the time, the price was speculated to be around 35,000 euros if the car arrived on the market in Europe. Related Video:
