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.

Listen to the Porsche Macan's exhaust note ahead of its LA debut

As if we need further proof that the Porsche Macan won't just be another small CUV, it'll be a small Porsche CUV, the German automaker has released a video of the vehicle's raucous exhaust note. In short, the Macan will sport a far racier soundtrack than most of its competitors.
The raspy sound coming from one of the Macan's two turbocharged V6 engines sounds great (the video isn't clear as to whether we're listening to the base 3.0-liter or the Turbo model's 3.6-liter engine), and it's accompanied by a nice crackle on overrun. It isn't like a 911 or other flat-six model, but it is more or less what we expect a Porsche to sound like. We'll have all the details on the newest member of the Porsche lineup when it debuts later this month at the 2013 Los Angeles Auto Show. Scroll down for an official press release from Porsche, as well as the video of the Macan, and be sure to turn your speakers up.

Jaguar F-Type squares off against Porsche 911, Aston V8 Vantage with Chris Harris

Chris Harris is back on the job, taking on really really difficult car questions like: Which enormously sexy and good-to-drive, high-performance convertible is the top of the heap? As one of the hottest cars in the luxury space right now, the Jaguar F-Type S is, of course, in on the action. Competition comes in the form of the Aston Martin V8 Vantage Roadster and the Porsche 911 Carrera S Cabriolet. Sun-loving CEOs who despise test-driving need look no further.
Scroll on below for a fully featured (with a running time of more than 20 minutes) comparison video. Harris does his best to entertain - in a typically nitpicky and made-up-British-words fashion - and the moving pictures are lovely to look at. Kick back, pour a pint and get your weekend started off right.
