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 engine wizard Wolfgang Hatz resigns

Wolfganag Hatz has resigned from his position as Member of the Porsche Executive Board with responsibility for Research and Development. He has held that title since 2011. Hatz's storied career came to an abrupt end in September when he was suspended pending investigation into the Volkswagen diesel scandal. Before the Porsche job, Hatz was the head of engine and powertrain development for the Volkswagen Group. It has been alleged that he is at the center of the investigation into the company cheating on emissions testing, but so far there has been no direct link made to him, according to Porsche's announcement today. Hatz has worked at a variety of European automakers, including Audi, BMW, Opel, and Fiat. He is considered the father of the BMW S14 engine, which powered the E30 M3, and also developed the Porsche 911 Carrera RS 3.8. He was also very involved in Porsche's motorsports efforts, including the recent return to the prototype class and a short-lived F1 V12 engine project. Ulrich Hackenberg, most recently VW's lead engineer and a board member at Audi, was also suspended at the same time as Hatz and resigned shortly thereafter. It's not clear why Hatz waited so long to do the same, but Porsche claims his resignation was voluntary. Michael Steiner has been named Hatz's replacement as head of Porsche R&D. Steiner has been with Porsche since 2002 and seems like a forward-thinking sort, having headed the innovation and concepts division, lead Panamera development, and, most recently, been in charge of complete vehicle engineering. Prior to his time at Porsche, Steiner held positions at Daimler. The change in leadership is effective immediately. Related Video:

Porsche caught testing sub-Panamera-sized sedan

Anyone remember the Porsche Pajun? It was supposed to be Porsche's long-rumored entry level sedan before it mostly dropped off the radar. Now, it might have blipped its way back onto our screens, thanks to a series of spy shots showing what on the surface looks like a Panamera. While our spies point to this being a coupe mule riding on a shortened version of the Panamera's platform, we're leaning towards a smaller sedan. Even with the rear windows obscured, the wheelbase and driver's seating position (which we'll admit is remarkably low and coupe-like) seem wrong for a two-door model, even a disguised one. The cutlines in the rear doors look too deep to be camouflage, and based on the look of those door handles, the rear doors are definitely real. As for what's not real, we wouldn't read too much into those rivet-like things at the front and rear. They're just there to secure the camouflage. We might not be on the same page as our spies about what this car actually is, but they make a strong argument for its eventual styling, which should be a mix of 911 and Panamera. There's a slim strip of taillight hiding beneath the rear camo – you'll need to zoom way in, but the white housings are there – that reminds us of the new 911. It should be more Panamera in the front fascia, aside from the headlights, which might be the only styling element that draws inspiration from the 718. Based on the state of this car, we're thinking it's still quite early in the Pajun's development process. Whether the development timeline lines up with this 2019 prediction remains to be seen.
