Porsche finally moving ahead with flat four engine

When Porsche released the first Boxster in 1996 and the first Cayman in 2005, the idea was to create an entry-level model for the German automaker's sports car range. The latest iterations of both closely related models, however, have begun to encroach dangerously on the 911's territory, particularly in their newest GTS specifications. That could be about to change, however, with the introduction of a four-cylinder engine for the compact mid-engined coupe and roadster.
According to Automotive News, Porsche is finally preparing to launch a new boxer four engine in the Boxster and Cayman, following years of speculation. The engine would be based on the same architecture as the company's famous flat six, but with two fewer cylinders to cut weight. Don't expect it to cut much in the way of performance, however: Porsche chief Matthias Muller indicates that the new engine could produce as much as 395 horsepower - significantly more than even the 340hp flat six in the Cayman GTS, suggesting that the engine could even find its way into the 911 as well.
It's no more clear which markets would get the four-cylinder engine, either. But wherever it is offered and in whichever form, it wouldn't be the first time we'd see a Porsche with a four-pot engine. Not by a long shot. Both the classic 912 and 356 were powered by boxer fours, as was the 914 - not to mention the 718 pictured above and the iconic 550 Spyder. The front-engined 924, 944 and 968 packed inline-four engines, but the last of those were discontinued in the 1990s. The prospect of a four-cylinder Boxster/Cayman has been rumored for many years now, most recently joined by the possibility of a four-pot Macan as well.

Porsche 911 Aerodynamic prototype cheated the wind ahead of its time

You might think that sports cars would have the lowest drag coefficient of all cars. And yes, they do tend to be more slippery than, say, SUVs or convertibles, but the sleekest vehicles on the road tend to be EVs, hybrids and luxury sedans. Sports cars, on the other hand, have aerodynamically detrimental needs for downforce and additional engine cooling. Still, the Porsche 911 is better than most, and has only gotten more so over the years. Its relatively narrow track and compact form mean it has a smaller frontal area than some other sports cars, and the gradual sweeping back of its headlights and windshield have only augmented its capacity for cheating the wind.
This 911 prototype, however, is even more aerodynamic than most. It's based on a "G model" 911 from 1984, but employed such features as covered wheels, a new rear spoiler and a reprofiled front end to drop its drag coefficient from 0.40 to 0.27, making it as slippery as a modern sedan and better at cheating the wind than just about anything built up to that point, save for maybe the Tatra 77, Citroën SM or Tucker Torpedo.
Elements of this prototype ended up gradually making it into production Porsches for years to come, and you can clearly see early influences on the second-generation 964 and even on the 959. It's featured here as the latest installment in a video series on rare historic Porsches unearthed from the company archives, following previous clips that featured a rare V8-powered 911 and a mid-engined 911 prototype. Scope out the latest episode in the video below.

All Porsche 911s to get turbos in 2015?

Currently, Porsche builds two turbocharged 911s - the Turbo and the Turbo S (and their cabriolet counterparts). The rest of the 911 range, meanwhile, is motivated by either 3.4- or 3.8-liter flat-sixes of varying outputs. This clear separation could be set to change in the very near future, though, as rumors continue to swirl that Porsche's rear-engined range could switch exclusively to turbocharged power.
This time, it's Car projecting that the 911 range will go turbocharged as part of a mid-cycle refresh, with the base Carrera's 3.4-liter dropping to 2.9 liters and adding an iron lung, bumping the entry level 911 up to 400 horsepower. Yes, a 400-horsepower, entry level 911. The Carrera S, meanwhile, will retain its 3.8-liter engine, but will also benefit from turbocharging, increasing output to 530 horsepower and 520 pound-feet of torque. So basically, it sounds like the current, 520-hp 911 Turbo will become the next Carrera S.
What does that mean for Porsche's traditional high-performance models? Well, it's a safe bet that the Turbo, Turbo S and eventual GT2 will be producing seriously huge power figures. Based on pure speculation, we wouldn't be shocked to see a 600-hp Turbo, with the S and GT2 increasing output markedly from there.
