Porsche 911 GT3 dukes it out with MP4-12C on track and GT-R on spectacular roads

The Porsche 911 GT3 has always been a favorite among auto journalists and car enthusiasts alike, but with the introduction of the new 991-generation GT3, which is the first GT3 with electric power steering and no manual gearbox option, how does it stack up to the competition from McLaren and Nissan?
Evo's Jethro Bovingdon attempts to answer that question by pitting the rear-engine Porsche against the mid-engine McLaren MP4-12C on a racetrack and the front-engine, all-wheel-drive Nissan GT-R on some amazing, twisty European back roads. We won't give away the victor of either comparison, but we will say that, in Evo's test, the McLaren's 141-horsepower advantage doesn't give it as much of an edge over the Porsche on a racetrack as one might think, and the lack of a manual gearbox and the inclusion of electric power steering on the GT3 isn't detrimental to enjoying the car on a back road.
Watch the video below to find out which car Bovingdon prefers on road and track - we think you'll be happy to see him drift around turns every chance he gets.

The mid-engine Porsche backstory

As an automaker's identity evolves over years, its signature becomes defined by any number of factors - heritage (Mercedes-Benz), image (Lamborghini), or market share (Toyota). In the case of Porsche, it was an engineering quirk that forged the German company's most enduring character trait.
Porsche would not have survived - let alone, thrived - in today's saturated landscape had it not been for the 911, and that slope-tailed sports car wouldn't have sprung to life without its predecessor, the 356. While phenomenal success of those rear-engine icons built the company, forays into the mid-engine configuration have played a significant part in establishing the brand's identity.

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.
