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.

Next-generation Panamera will spawn variants, Sport Turismo in the running

A few years ago it took actual willpower not to consider what kinds of cool derivatives Porsche could make with the Panamera. Our fancies were helped by patent drawings of a Panamera convertible, rumors of a two-door 928 GT and internal Porsche sketches of such a car, and report after report after report that the current, second-generation Panamera would begin to expand the family. That hasn't happened, but according to a new report in Auto Express, the next Panamera will be the one to begin the bifurcation. Wolfgang Hatz, the brand's head of research and development, told the mag that, "We have prepared it for a lot of derivatives, personally I like very much the Sport Turismo." The Panamera Sport Turismo, remember, was the hybrid, concept wagon that rolled into the 2012 Paris Motor Show and made everyone ask, "Why didn't you build this design from the beginning?" It could have been Hatz's English, but after professing his ardor for the Sport Turismo, the executive said, "But there is a good chance for more derivatives." We're not sure if that means the Sport Turismo is all but approved, or if he was speaking of the third generation Panamera's new MSB platform in general. Even though Hatz mentioned a coupe and convertible, it sounds like that latter variant won't be happening, Hatz saying that the brand already has the Boxster and 911 Cabriolet. We're willing to forgive that omission – who's really looking for a four-door convertible, anyway? – and welcome the Sport Turismo first if Hatz will please please please get us a new 928.

Are you the 2017 Porsche 911 GTS Targa?

Our spy shooters have caught a strange, mash-up beast wearing a Porsche badge. Superficially, this is a facelift for the 911 Targa that features new bumpers, door handles and a redesigned engine cover, along with new light graphics for the front and rear lights. But have a look around back, and you'll find two inboard exhaust pipes; they aren't right up against each other as on the 911 GT3, but are spaced about five inches apart. The shooters said the first time they saw that arrangement was last winter, on a convertible during testing. We saw it again more recently in spy shots of what was thought to be the 911 GTS coupe prototype at the track. But when the production GTS arrived, it wore the traditional quad-pipe at the corners. The theory put forward by the spy photog: the current GTS has a naturally aspirated engine, but facelifted prototypes they've been seeing all have turbo engines, so this could be the facelifted Targa coming in 2017, after the 991-model 911 gets a refresh. In that case, the GTS coupe prototype at the track would have also been a post-refresh, turbo-engined GTS. It's only a hypothesis, but more than one outlet has reported that Porsche is going all-turbo for the updated 2015 models – the new exhaust position and those 911-Turbo-like vents could be their identifiers. We expect to find out when the lineup is unveiled at the 2015 Geneva Motor Show, possibly codenamed 992 instead of 991.2.
