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 Macan spied, all lit up and dodging flurries

We've seen the upcoming Porsche Macan testing on surface roads and even on the Nürburgring, but here we have our first spy shots showing a disguised prototype doing some winter testing in snowy conditions. Still obscured by plenty of camouflage attempting to mimic its larger Cayenne sibling, we still can't get a clear look at what the Macan's face and rump are going to look like, although it does appear that some details for the front lighting are starting to emerge.
Below the headlights, those are obviously decals trying to look like turn signal lenses, but it appears that there is still some sort of lighting being hidden judging by the small circles cut into the camo. Lower in the fascia, we can also see there are LED running lights not revealed on past prototypes. The entire rear end of this Macan prototype still appears to be tacked-on camo, but the side view appears to be in production form save for the poorly disguised rear quarter windows.
As we've seen in the past, Porsche engineers are still testing the Macan alongside the Audi Q5 with which it shares its platform. There has been no word as to when we could expect to see the Macan in production or concept form, but we'd have to guess that this compact crossover is getting ready to shed its camo very soon.

Motor Trend holds World's Greatest Drag Race for the third time

As part of Motor Trend's Best Driver's Car competition, the buff book has held its third iteration of the World's Greatest Drag Race. With an airfield and a dozen of the world's finest performance cars at its disposal (oh, and a helicopter), the MT team did what any good group of enthusiasts would do, and tried to figure what car could cover a quarter mile the quickest. World's greatest drag race, indeed.
The contestants, as MT points out, cover a huge variety of engine types, drivelines, aspiration types and body styles, making for a genuinely varied and interesting field of competitors. Here's the full list of cars taking part.
