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.

Manuals return to the Mini lineup for 2021

The 2021 Mini Cooper will offer a manual transmission again, after the 2020 model had to go without a stick shift due to problems certifying that powertrain. It had been hoped that the emissions issue would be straightened out in only a few months, but as it turned out, Mini had to go through the entire 2020 model year with its cars offering only two pedals. The 2020 Cooper and Cooper S models got a seven-speed dual-clutch automatic, while the John Cooper Works variants and the ALL4 versions of the Clubman and the Countryman got an eight-speed unit. For 2021, the standard Mini Cooper with the 134-hp 1.5-liter turbo three-cylinder will offer a six-speed manual in the hardtop, four-door, and convertible body styles. The 2021 Mini Cooper S, with its 189-hp 2.0-liter turbo four, also will come standard with the six-speed stick in hardtop, four-door, and convertible form. The John Cooper Works hardtop, with its 228-hp 2.0L turbo, shares in the manual-transmission goodness, but the JCW convertible remains automatic-only, with the seven-speed DCT. The 2021 301-hp John Cooper Works GP hardtop will be eight-speed automatic only. For the 2021 Clubman and the Countryman, the picture is still murky. It's likely that the JCW Clubman and JCW Countryman, which also get the 301-hp engine, will continue to be offered only with the eight-speed automatic gearbox, although the less-powerful versions could get a stick shift again. Mini says, "Manual transmission offerings will be confirmed once 2021 model year information for these models is released later this spring." Given the persona Mini has cultivated, this brand seems like one that should continue to offer stick shifts for as long as possible. Mini spokesman Andrew Cutler claims that the Mini hardtop generally has had the highest take rate for manuals in the U.S. market, with 45% buyers of the (2019-model) John Cooper Works version opting to row their own gears.

Mini moving away from leather as it shifts to recycled interiors

In the midst of a far-reaching transformation, Mini announced that it will gradually phase leather upholstery out of its range in the coming years. It plans to fully adopt recycled fabrics in a bid to make its cars more eco-friendly. "We don't need leather any more in the future, because we don't believe it's sustainable. We're totally convinced that we will have modern and high-value products without leather," affirmed Oliver Heilmer, the firm's design boss, in an interview with British magazine Autocar. He didn't reveal when leather will disappear completely, however. Demand for real hides nonetheless remains relatively high; Autocar pointed out that about 54% of the new cars that Mini sells in the United Kingdom are ordered with leather upholstery, which is generally either sold at an extra cost or made standard on upmarket trim levels that come with a price premium. We've asked the company's American division to provide us with the take rate on our shores, and we'll update this story if we learn more. Mini's shift towards recycled materials is ongoing. As of writing, 100% of the fabric it uses to upholster seats is recycled, according to the same report, and 70% of the material underneath the cloth is, too. Looking ahead, it will make interior trim pieces with recycled materials. Cork was used in the Urbanaut concept, for example. Heilmer's comments add another piece to the next-generation Hardtop puzzle. Tentatively due out in 2023, so possibly as a 2024 model, it will embody the nameplate's biggest evolution since BMW rebooted it in 2000. It will likely still be offered with two or four doors, though the convertible is allegedly living on borrowed time, and both will be smaller than their respective predecessors. It will also showcase a purer approach to design. Heritage will continue to shape the exterior design. Inside, the theme will come "more from a home perspective rather than an automotive one," Heilmer noted, which partially explains why stylists want to incorporate different materials. His team is still debating whether features like the toggle switches need to come back, or if they're outdated. Most can be replaced with a menu in the infotainment system, but tapping a screen is not as satisfying and a lot more anodyne than flipping a switch. Designing a new Mini requires balancing the past and the future. "We're looking to create a timeless design.
