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 GT3 wows the crowds in Geneva

Porsche has a long and storied history of taking its range-topping 911 sportscar racing, with an enviable record of achievements in tow. The latest machine with which the automaker will take to the track can be seen above: the fifth-generation 2014 911 GT3.
With 475 horsepower strumming through the 3.8-liter six-cylinder boxer engine, this is the pinnacle of naturally aspirated performance from Porsche. It can go from 0 to 60 in just 3.3 seconds, hit a top speed of 195 miles per hour and has lapped the Nürburgring Nordschleife in less than seven and a half minutes.
A dual-clutch PDK transmission (no standard manual gearbox will be offered) with shorter gearing than lesser 911 models sends power to the rear wheels. Providing forward motion isn't the only thing those rear wheels will be doing - Porsche says the 2014 911 GT3 is fitted with the manufacturer's first active rear-wheel steering.

Watch 1,208 Porsche 911s collect at Silverstone for world record

Porsche has been spending the majority of 2013 celebrating the 50th birthday of the 911, with its latest stunt taking the German brand to the home of British motorsports, Silverstone. To celebrate, Porsche invited enthusiasts to take their personal 911s on a lap of the former airfield, and boy, did the Porschephiles show up. 1,208 911s took part in the lap around the Grand Prix circuit, making it the largest-ever gathering of the iconic, rear-engined cars.
This wasn't just a celebration of 50 years for the 911, though. Funds raised were channeled towards Hope For Tomorrow, a cancer charity that works with the United Kingdom's National Health Service in operating mobile chemothereapy units that make life just a little bit easier on cancer patients.
Take a look at the long video below, and enjoy the passing of what are likely examples of every 911 model ever built.
