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.

See what the Chevy C7 ZR1 may be benchmarked against

One of the greatest things every Corvette has had going for it, and also one of the most re-used arguments against it, is its price-to-performance equation - long before the Nissan GT-R became the de facto Porsche 911 comparator the Corvette spent decades as Exhibit A. Depending on which side of the argument you stressed, supporters crowed about how much performance you got for how (comparatively) little, detractors carped on how little you got everywhere else in the bargain.
It appears Chevrolet is working as hard as ever to render the argument meaningless. Spy shooters at KGP captured a convocation of European birds of prey leaving the General Motors test center, and aimed at benchmarking the C7 Corvette ZR1. The road train comprised of two C7 Corvette Stingrays, a 2013 Corvette ZR1, McLaren MP4-12C, Ferrari 458 Italia, Audi R8 V10 Spyder and Porsche 911 Carrera S and it was last seen heading down the same kinked-up back roads used to hone the Corvette Stingray.
The C7-series ZR1 and its possible 700 horsepower are still a ways off. If it really is being positioned to compete with the celestial exotica in the testing group, could it be the first Corvette to regularly be the first answer to the question "Cost no object, which would would you rather have?"

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."
