Porsche reportedly working on new turbocharged flat-four boxer engine?

These days, we've seen just about every automaker dropping cylinders in an effort to appease tightening fuel economy and emission standards - and Porsche is no exception. Nearly three years after introducing an all-new V6 powerplant under the front hood of its Panamera sedan (launched with a range of V8 engines) comes word that Porsche is working on an all-new turbocharged flat-four boxer to replace the flat-six engines mid-mounted in its Cayman and Boxster models.
Specifics have yet to be learned, but reports say the engine is a derivative of the current 3.8-liter six (shown above) found under the rear decklid of the Carrera S, yet with two fewer cylinders. Fitted with a turbocharger, direct-injection and the automaker's VarioCam Plus, the new all-aluminum 2.5-liter flat-four will likely develop upwards of 350 horsepower and 360 pound-feet of torque. Redline should be about 7,500 rpm. Initial indications say that Porsche will only offer the new engine with its seven-speed PDK dual-clutch automatic, tuned to take advantage of the low-end torque, but a traditional six-speed manual gearbox has not been ruled out. Despite the loss of two cylinders, enthusiasts will likely embrace the new engine as it promises to be lighter, more fuel efficient and more powerful than the 2.7-liter and 3.4-liter sixes in the Cayman/Boxster today.
Even though Porsche has been using Volkswagen Group engines for years (e.g., Cayenne V6, Cayenne Diesel and upcoming Macan), all indications are that the new flat-four will not be shared. Instead, it will be kept in-house for the automaker's sports cars and possible future fitment in an entry-level 911.

eGarage video features Helmuth Bott's personal Porsche 959 prototype

"We thought we were going to build a super-911," said Peter Schutz, former CEO of Porsche AG of the development of the Porsche 959. That was before it started getting expensive. At that point, Helmuth Bott, Porsche R&D director got frightened. Costs ballooned because of the all-wheel drive, sequential turbocharging and other technology Porsche had never even thought about when it set out to build a 911 to compete in Group B. Schutz continued, "The amount of resources we were committing got totally out of hand." Instead of pulling the plug, Bott doubled down and drew on the strength of his brilliant team to build a car whose impact is still echoing aross the industry.
"It's probably one of our most prized possessions" says Don Leatherwood, Director of the Brumos collection where Dr. Bott's personal prototype resides, and where Frazer Spowart went to see the car and create a video for eGarage. Check out the sights and sounds of the 959 before it was the 959, and get personal takes on the car from Hurley Haywood, Peter Schutz and Don Leatherwood. Keep reading to see the video.

Porsche names new motorsport chief

Though it may have expanded into crossovers and sedans, Porsche is still a company with racing at its heart. You might even argue that Cayenne and Panamera sales only serve to fund the company's motorsports activities. Competition-spec 911 coupes still make up a large portion of the grid in any GT racing series, and those activities are presided over by the Porsche GT division (separate from its LMP1 program), which has just announced a changing of the guard.
Porsche's GT unit - which is responsible both for racing models like the 911 RSR and road-going models like the 911 GT3 - has until now been steered by Hartmut Kristen (pictured above, left) in his capacity as Vice President of Motorsport at Porsche AG. During his ten-year tenure, Kristen gave birth to the RS Spyder that competed in the American Le Mans Series and the pioneering 911 GT3 R Hybrid. He also fostered what Porsche characterizes as "arguably the most comprehensive youth development program in motor racing" and saw the marque return to Le Mans last year with a dominant 1-2 class victory.
Kristen, now 59 years old, is leaving the German automaker, but will remain an advisor to the company's R&D department. Taking over as VP of Motorsport will be Dr. Frank-Steffen Walliser, who has until now been head of the 918 Spyder project (a responsibility he will continue). Walliser (pictured above, right) was previously Porsche's general manager for motorsport strategies and will now be responsible for Porsche's GT projects on and off the track, while Fritz Enzinger continues at the helm of the LMP1 program in pursuit of better results next year than the 919 Hybrid achieved at Le Mans last month.
