Porsche 911 R is made for the purist

Who wouldn't welcome a new version of the Porsche 911 with ultra-light weight, a GT3 RS motor, a stripper interior, and a core philosophy of driving fun over outright lap times? The iconic Porsche 911 has been getting larger and more complicated with each passing generation, and that hasn't sat well with every engineer at Porsche. So there's a ready market out there for 911 R, a limited-edition show stopper of just 911 cars, due to start production in Zuffenhausen, Germany, in May. It's a car that combines a unique version of the six-speed manual gearbox, plenty of raw, naturally aspirated flat-six power, and all the feel of a cut-price version of the 911 GT3 RS pseudo racer. Yes, Porsche is bringing the beloved six-speed stick back to the sharp end of the 911, even though the brand's quickest cars are now dominated by the seven-speed dual-clutch transmission (and the less loved seven-speed manual). Porsche insists that the RS is still the 911 to have if it's stopwatch-bashing you need to do. Instead, the 911 R developers focused on trying to give it the most driving purity it could cram in. The most traditional way for motorsport operations to do that has always been to rip out weight. And Porsche Motorsport didn't diverge from the plan. The 911's rear seats have been thrown out, along with a raft of other pieces Porsche Motorsport thought it could either do without completely, redesign to be lighter or stronger, or both.

The pound-cutting starts at the body and bores all the way into the 911 R's chassis components, though there are some obvious nods to the marketing department that survived the dietician's axe. There is a lot of 911 GT3 in the body, with a combination of a carbon fiber (bonnet and front guards), a magnesium roof, polycarbonate front and side "glass," and aluminum everywhere else. The R cuts 110 pounds from the next-lightest 911 variant, hitting 3,020 pounds on the scales. While the 911 R has lurid (and deletable) red or green racing stripes as standard, it's not supposed to be as wild looking as the GT3. Porsche replaced the GT3's adjustable, tall-standing rear spoiler with a more-subtle pop-up version, and the R uses a rear diffuser under the bumper to offset any loss of rear downforce. The rear seats are gone, and the two remaining seats use carbon fiber shells upholstered in tartan cloth (another nod to early 911s).

Porsche 911 GT3 RS getting all-new atmospheric engine

Porsche surprised many of its most puritanical enthusiasts when it took a decidedly more usable approach with the current 911 GT3. But when the new GT3 RS debuts, it promises to be a much more extreme departure. And a big part of that comes down to the engine. At the Detroit Auto Show this week, Auto Express spoke with Porsche R&D chief Wolfgang Hatz – who also happens to be head of engine and transmission development for the entire Volkswagen group. Hatz revealed that Porsche has developed a completely new engine for the GT3 RS, and while previous rumors suggested the RS would go turbo to fill in for the lack of a GT2 (and make the most out of its displacement), Hatz confirmed that it will be naturally aspirated. Considering that Porsche rarely goes downwards when it comes to 911 engine displacement, only upwards, we'd expect the new RS to pick up where the previous 4.0 left off. The new GT3 RS is also expected to pack a more extreme suspension, aero and stripped-out interior, but those hoping for an old-school approach may be disappointed to learn that the new RS will (at least at launch) only be available with the seven-speed dual-clutch transmission – though a manual version could follow if there's enough demand. In a related development, Hatz also hinted that the Cayman GT4 could debut at the Geneva Motor Show in March, with an even more extreme approach than the previous Cayman R. The new top-of-the-line Cayman is reportedly being developed to comply with GT4 class racing regulations but be fully homologated for road use. Related Video:

Patrick Dempsey to take break from racing after career season

The popular American actor has decided to take a step back from racing to focus on his "family and acting career." Outside of motorsports, Dempsey's tenure on the hit TV show Grey's Anatomy as Derek Shepherd ended last year, as did his 16-year marriage to makeup artist Jillian Fink. They have since reconciled. Reaching the top step of the podium During that same year, Dempsey finally reached the top step of the podium in his professional sports car racing career, winning the Fuji round of the 2015 FIA World Endurance Championship. Earlier in the season, he placed second in class in the prestigious 24 Hours of Le Mans endurance classic. His Dempsey-Proton Racing Porsche squad ended 2015 sixth in the GTE-Am standings. Along with four starts at Le Mans between 2009 and 2015, Dempsey competed in a total of 68 races between Grand-Am, ALMS and the recently formed hybrid of the two -- The IMSA WeatherTech SportsCar championship. He scored nine podiums, which includes high profile races such as the Rolex 24, Sebring 12 Hours and Petit Le Mans at Road Atlanta. Patrick Dempsey to focus on "family and acting" in 2016 But he will not add on to his growing racing resume this year. Dempsey has released a statement, announcing that he will not compete in any events this season, although his team will continue to do so. My motorsports journey has been a rewarding one and allowed me to meet so many interesting people. While the focus so often is the performance of the car, in reality it is all the various personalities, from team mates to competitors to officials to fans that I remember the most. I have loved being part of part of different teams and sharing the experience with so many great friends. I want to thank everyone who made this possible and helped me along the way. I also wanted to especially thank the fans for their support and friendship. None of this would happen without you buying the tickets and attending the races, so I am grateful for that investment in my passion. It makes me especially happy to see how many people have become race fans during my racing career. At this point in my life, after an amazing season thanks to my friends at Porsche and TAG Huer, I need to take a step back and focus on both my family and my acting career. Dempsey-Proton Racing will continue on racing a Porsche 911 RSR in the World Endurance Championship season. I hope my schedule permits me to enjoy some race weekends at least as a team owner.
