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.

Porsche planning new 911 Speedster as 550 tribute

Some look at the emergence of a new Porsche 911 and see a car. But to Porsche engineers, it might as well be a reset button. Because every time a new 911 comes out, it sets off a tidal wave of new variants to follow, including convertibles, turbos, targas, GT3s... the works.
The next down the pipeline, though, could be one of the most desirable. That, according to German publication Auto Bild, will be a new 911 Speedster. When it arrives early in 2015, the special roadster will reportedly be limited to just 550 examples in tribute to the original 550 Spyder.
It'll reportedly have hidden door handles, a chopped-down windshield and a fabric top to be used only in case of emergency, manually disappearing below a carbon-fiber cowling. All of which makes it sounds as much like a bigger version of the Boxster Spyder as a successor to the last 911 Speedster (pictured above), and that's no bad thing at all.

Porsche busts out new Boxster GTS and Cayman GTS

Baby 911. The poor man's Porsche. That's what they called the Boxster when it debuted some 20 years ago. They said the same of the first Cayman when it arrived a decade later, but they stopped saying it when the latest iterations hit the scene two years ago. That's because Zuffenhausen's entry-level models have long since stepped out of their big brother's shadow and into their own. And that's all the more true of the new Boxster GTS and Cayman GTS.
Based on the Boxster S and Cayman S, the new GTS models benefit from an enhanced 3.4-liter flat six that produces 330 horsepower and 273 pound-feet of torque in the roadster or 340 hp and 280 lb-ft in the coupe - representing an increase of 15 hp and 7 lb-ft in either model. Both also come with the Sport Chrono package as standard, along with adjustable suspension and 20-inch alloys, blacked out to match the dynamic headlight surrounds and other muted trim.
Those disappointed by the unavailability of a manual transmission in the fire-prone 911 GT3 will be pleased to note that a six-speed manual comes standard, but those enamored of letting a pair of clutches shift themselves seamlessly will want to spring for the optional seven-speed DCT. So equipped and with launch control engaged, the Boxster GTS will rocket from a standstill to 62 miles per hour in 4.7 seconds, while the incrementally lighter, more powerful Cayman will hit it in 4.6. Either way you're looking at a third of a second quicker than the Boxster/Cayman S. There's also a 20-millimeter lowered suspension on offer for track-day enthusiasts.
