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:

Le Mans-winning Porsche 956 up for auction at Pebble Beach

Collectors looking to get their hands on a piece of racing history will want to be in Monterey this August. That's where Gooding & Company will be auctioning off the genuine Le Mans winner you see here. One of the finest examples of the Group C era, this 1982 Porsche 956 won the 24 Hours of Le Mans in 1983 – the eighth time the German marque won the legendary French endurance race, en route to the record seventeenth win it racked up at La Sarthe this year. This 956 was the third of only ten examples made, complete with Rothmans livery and unimpeachable history. It debuted at Le Mans in 1982, where it placed second behind another Rothmans-liveried 956, and went on to win the next four races it entered. The following year, the two Porsches switched places in the winner's circle at Le Mans, securing this car's place in the annals of racing history. Now set to cross the auction block at the Pebble Beach Concours d'Elegance, Gooding projects this most historically significant Porsche to fetch between $7,000,000 and $9,000,000 once the gavel drops. According to the Sports Car Market database, that would make this the most valuable Porsche ever sold at auction, eclipsing the 1972 Porsche 917/10 Can-Am racer that Mecum sold for $5.83 million in Monterey three years ago. It would also far exceed the ˆ2.35 million ($3.15m) paid at RM's auction in Paris last year for another Rothmans-liveried 956 that completed the 1-2-3 finish at Le Mans in '82. That is, assuming 956 #003 sells this time: the last time it crossed the auction block, it failed to sell after a high bid of $2 million. Le Mans-Winning Rothmans Porsche 956 Roars its Way to Gooding & Company's Pebble Beach Auctions SANTA MONICA, Calif. (June 19, 2015) – Gooding & Company, the official auction house of the Pebble Beach Concours d'Elegance®, is thrilled to announce the addition of one of the most important and desirable competition cars of all time to its Pebble Beach Auctions. The 1982 Porsche 956, chassis 003, was the outright winner of the 1983 24 Hours of Le Mans and the most successful example of this revolutionary and dominating series of Group C cars. The sale of this factory Porsche racing machine presents an incredible opportunity to own a significant piece of motorsport history and it is sure to be a highlight of Gooding & Company's internationally renowned auction, taking place on August 15 and 16, 2015 in Pebble Beach, California.

Porsche still deciding on one or two new 911 plug-in hybrids

Back in March, Porsche CEO Oliver Blume told Autocar that the coming Porsche 911 plug-in hybrid "will be the most powerful 911 we've ever had." That quote portended a 992-series 911 with 700 horsepower or more. A new report in Auto Express, however, suggests Porsche is having energetic debates about just what the 911's hybrid strategy will be, and that the only agreed-upon plug-in hybrid 911 so far is a milder version to sit in the middle of the range. Putting all our rumors in a row, in January, Automobile reported on an electrically-assisted 911 with 485 hp and 561 pound-feet of torque. The new AE piece effectively endorses that, saying the mid-range hybrid would follow the program established by the all-wheel drive Cayenne e-Hybrid that produces a combined 455 hp and 516 lb-ft. The 911 would naturally use a flat-six instead of the Cayenne's 3.0-liter V6, and the sports car would be tuned for better sound response and sharper reflexes. AE says fuel economy for this hybrid should be at least 80 eMPG, with emissions of less than 80 grams per kilometer. The current base Carrera is currently rated at a maximum 38.2 mpg in the UK, with minimum emissions of 169 g/km. The hybrid, fitted with a double-clutch gearbox and Porsche's mechanical all-wheel-drive system, could run from a stop to 62 miles per hour in less than four seconds, making it more efficient than a base Carrera and much faster than a Carrera 4S. AE says there remains only "the potential for Porsche to add a second, more powerful hybrid 911," and says its sources claim that's what's "causing the most consternation behind closed doors." This one would be the twin-turbocharged, 700-hp beastie that, as a series production car, would have a hard time not usurping the 540-hp Turbo, 580-hp Turbo S, and 607-hp Turbo S Exclusive. True, the hybrid would be handicapped with a 550-pound battery pack, but the instant acceleration and handling benefits of electric AWD — with no connection between the axles — could provide the final edge over the other three. As such, it makes sense that there'd be a whole lot of debate about a flagship 911 hybrid. On the other hand, such a monster seems like an eventuality in view of Porsche's electrified aspirations, the lessons gained from the 918 Hybrid and the 919 Hybrid Le Mans racer, and the fact that CEO Blume has already spoken. The Stuttgart carmaker expects a sales mix of 25 percent electric, 25 percent hybrid, and 50 percent conventional powertrains by 2025.
