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.

Are you the next Porsche 911 GT3 RS or GT2?

Porsche typically keeps to a suitably fast schedule when it comes to rolling out increasingly hard-core performance versions of the 911. After the 997 Carrera debuted in 2004, the GT3 version followed in 2006, and by the end of the 2007, Porsche had rolled out both the GT3 RS and GT2 versions. Then the facelifted 997.5 came out in 2008 and it was back to the start: the GT3 came in 2009, the GT3 RS and GT2 RS in 2010, and the GT3 RS 4.0 in 2011. But things have slowed down some with the latest 991 generation.
The new Carrera came in 2011 and the GT3 followed in 2012. By recent history's example, we should have at least two more hardcore models by now, but we don't. Maybe the engineers in Zuffenhausen have had their hands full fixing the spontaneous-combustion issues with the existing GT3, or maybe their attentions have been focused elsewhere altogether. But if these spy shots are anything to go by, it seems like they're back on the job.
Now we don't know if this prototype foreshadows a new GT3 RS or a GT2, but it sure looks more hard-core than the existing GT3 that many purists have derided as too soft, what with its automatic transmission and four-wheel steering.

2017 Porsche 911 Turbo First Drive [w/video]

Remember when turbos were a big fat middle finger to the naturally aspirated status quo? The horsepower renaissance has seen the forced induction phenomenon go from badass add-on (Turbo 'Vette!) to battle cry for efficiency (Kia Optima Turbo). From econoboxes to high-end holdovers like Ferrari and Aston Martin, everybody's doing the turbo shuffle. But what does that mean for the gang from Stuttgart – and more importantly, the top-of-the-line 911 that has called itself Turbo since the mid-1970s? I spent a day in the 2017 Porsche 911 Turbo and Turbo S to find out. Now is a particularly fitting time to evaluate the latest iteration of the venerable Porsche 911 Turbo. Our scrutiny comes at a moment when standard-issue Boxsters, Caymans, and Carreras have finally adopted turbocharged platforms. The Turbo S has a top speed of 205 mph, marking the first time the model has crested the 200-mph barrier. Spoiler alert: Rather than radically transforming its long-evolved essence, the 2017 Porsche 911 Turbo has made incremental changes that makes it, well, more Turbo than ever. Horsepower for the Turbo and Turbo S climbs 20 each, to 540 and 580, respectively; 0-60 times drop to a scant 2.9 and 2.8 seconds, and these top dogs now have terminal velocities of 198 and 205 miles per hour, marking the first time the model has crested the 200-mph barrier. The forced-induction flagships have different engine hardware, another first for the lineup, with the S gaining larger turbo impellers and housings. A revised differential enhances the precision of power transfer, while the PDK dual-clutch transmission (the only gearbox available) gains a centrifugal pendulum for smoothness. The dynamic engine mounts now work harder for crisper response, and the variable damping rates have been extended at both ends for a wider range of settings. If you're a fan of hanging the tail out, you'll be pleased to know that a new Sport mode enables greater yaw angles. And if you dig indiscreet bursts of acceleration, there's now a Dynamic Boost function that preps the drivetrain for a little extra oomph by dropping down a gear and holding the throttle open to maintain turbo pressure, increasing torque from 487 to 523 pound-feet, and from 516 to 553 lb-ft in the S. Standard equipment now includes a Sport Chrono Package, camera-equipped parking sensor, and the Porsche Dynamic Light System. Engine flexibility is outstanding, allowing peak torque to start at only 2,250 rpm.
