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 911 Cabriolet refresh may hide new engine

If we learned nothing else from our recent frolic through Porsche's secret museum, it's that the automaker goes to incredible lengths to disguise future products during initial testing. Just as a number of cars in that Stuttgart bunker hid the true identity of developmental mules (like the Audi-V8-powered 911), such could very well be the case with these spy shots showing what, on the surface, appears to be simply a facelifted 991 911 Cabriolet.
Similar to what we saw last month on a 911 coupe, this Cabriolet has obvious styling modifications made to the front and rear fascias suggesting that the 911's still-fresh appearance is already set to get a few tweaks. The big news here is at the rear of the car. The additional vents on the lower edge of the fascia and the mocked-up vent above the engine leads our spy photographer to believe that a new engine could be tucked under the body work - likely a smaller-displacement, turbocharged flat-six focusing more on improving fuel efficiency and reducing exhaust emissions rather than performance.
We last heard rumblings of such a detuned 911 back in August, but could this be our first look at said new model? Have a look for yourself, and let us know what you think - either about this mule specifically or the idea of a "green" 911, in Comments below.

Porsche 911 GT2 caught testing, is super bad

Look what spy photographers have spotted sprinting around the Nürburgring. Our shooters nabbed a few photos of the all-new Porsche 911 GT2 in its native habitat without any of the bulky camouflage or cladding we're used to seeing. The result is our first truly clear view at the upcoming successor to the GT2 throne. From the looks of it, the new model will boast wider fender arches front and rear, and hefty air intakes set into the machine's hips should help feed a beastly 3.8-liter flat six-cylinder engine. Early guesses put the engine output somewhere around 560 horsepower.
Mated to a seven-speed dual-clutch transmission, the engine should propel this rear-engined heathen to 62 miles per hour in under three seconds. Top speed? Try somewhere around 200 mph. If that's true, the next-generation 911 GT2 will be the fastest 911 in Porsche history.
