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:

Bugatti and Rimac joint venture profitable 'beyond expectations'

WARWICK, England — The joint venture between Croatian electric carmaker Rimac and Bugatti has been far more profitable than anticipated as the two brands work on developing vehicles together under one roof, Rimac's top executive said on Wednesday. "It's highly profitable and cash flow positive beyond anybody's expectations," Rimac CEO Mate Rimac told Reuters in an interview at the UK offices of the carmaker's Rimac Technology unit in Warwick. "It's such a win-win situation for everybody." Rimac added the joint venture has brought "lots of synergies going both ways." The Rimac Group comprises the Bugatti-Rimac JV, producing the electric sportscar Nevera and the Bugatti Chiron — which is owned 45% by Porsche AG — and a technology unit which supplies battery systems and powertrain components to other carmakers. Earlier this year the group raised 500 million euros ($519 million) in a new funding round. Rimac's CEO said the company has developed a "really close strategic relationship" with Porsche, which was listed by its parent Volkswagen in October. Porsche holds a 20% stake in the Rimac group. "We are really collaborating on many levels, developing and producing lots of key elements of their (Porsche's) future hybridization and electrification," he said. Rimac's CEO said the group must become more like Ferrari with a predictable, stable and profitable business before it can contemplate an initial public offering. "They (Ferrari) make projections and they always achieve," he said. "What I want to have is some kind of stability and certainty before we do an IPO because we don't want to make promises we can't keep." An IPO could happen anytime from three years to a decade from now, and could involve going public as a group or spinning off a unit, he said, but is definitely coming because "we obviously have financial investors that at some point want to exit."

Jack Olsen built one Porsche to do it all

Jack Olsen has built himself a lair called the 12-Gauge Garage, and inside that garage he built a lairy Porsche 911 nicknamed Black Beauty II. Although it looks like one of Stuttgart's models from the sixties or seventies, it is actually four decades of 911 gubbins from 1965 to 2000 thrown under one shell: the lightweight body is from 1972, the transaxle from 1977, the brakes from a 1986 Turbo, the engine from 1995, for example. It weighs 2,400 pounds and it's got 272 horsepower to get it going, but it's still a pure Porsche, Olsen saying, "If you stop thinking about what you're doing, it will remind you in very abrupt ways."
Olsen said the real point has been to have one car that does it all, so he does everything in his 911 from neighborhood runs to 7-11 to track racing - he loads the aero bits in the car and bolts them on trackside. And he says he'll never stop tweaking the suspension.
You can watch and hear the rest in Olsen's words in the video below.
