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.

VW confirms development of 10-speed dual clutch, 134-hp/liter diesel

Each year, the Vienna International Motor Symposium showcases some of the up-and-coming technologies automakers are engineering for the use in passenger cars, and Volkswagen AG CEO Martin Winterkorn revealed some big developments VW is working on for its future products. Winterkorn discussed a multi-faceted approach that VW is looking to reduce its fleet fuel consumption and exhaust emissions.
Some of the bigger news he discussed included a "high-performance" diesel engine that will produce 134 horsepower per liter and a 10-speed DSG automatic transmission. While no specific applications were mentioned, we can only hope this is for the Audi R4 we keep hearing about.
Another topic he touched on that caused us to perk up our ears was had to do with VW's plug-in hybrid technology. While we know the PHEV versions of the Audi A3 and Porsche Panamera are on the way, Winterkorn also said that these two models will be followed up by Golf, Passat, Audi A6 and Porsche Cayenne plug-in models. Scroll down for a press release highlighting the automaker's future fuel-saving initiatives.

Porsche updates 919 Hybrid LMP1 for 2015 assault [w/video]

Last season, Porsche returned to the top level of endurance racing with the 919 Hybrid, picking up a mantle that has seen the German marque win the 24 Hours of Le Mans a record sixteen times – more than any other manufacturer ever to compete at the legendary French race. Of course, Porsche didn't beat its sister company Audi right out of the box, but managed to win the last race in the FIA World Endurance Championship in Brazil before the season was done. This year it undoubtedly hopes to do even better, and this is the machine with which it will endeavor to take the top honors. Newly revised and optimized for the 2015 season, the new 919 Hybrid was just revealed on the eve of the first test session of the season at the Paul Ricard test track in the South of France. It may look largely the same as the model it succeeds, but benefits from numerous advancements made to help Porsche catch up with Audi and Toyota. For starters, Zuffenhausen has opted to step up to the eight-megajoule category, favoring the electric side of its hybrid powertrain over the internal combustion engine. So the compact 2.0-liter turbocharged V4 now drives in excess of 500 horsepower to the rear wheels, and the electric motor – powered by two energy recovery systems and a liquid-cooled lithium-ion battery – kicks in upwards of 400 hp to the front wheels. The rest of the package has been comprehensively updated as well, giving it a lower weight, improved rigidity, revised suspension and reshaped aerodynamic elements. Porsche will field two cars at most of the races this season, but will increase its team to three cars for certain races – one in black, one in white and one in red. Following the "prologue" test session at Paul Ricard this weekend, the season kicks off with the 6 Hours of Silverstone on April 12, when the new Porsche 919 Hybrid will take on the similarly revised Audi R18 E-Tron Quattro and Toyota TS040 Hybrid for the first time in earnest.
