Porsche reveals new 911 Turbo Cabriolets, starting from $160,700*

Porsche has come a long way from the days when its entire model line revolved essentially around the 911, but its prototypical rear-engined sports car is still what it's known for best, and still keeps the German automaker pretty busy. With a seemingly endless array of variations on the theme, the 911s just keep on coming until a new generation arrives and then it starts all over again. And what we have here is the new king of the hill (for now, anyway).
Set to debut at the Los Angeles Auto Show a little less than two months from now are the new Porsche 911 Turbo Cabriolets. And no, that's not a typo: that's cabriolets, plural, because what you're looking at are two new models. First up is the 911 Turbo Cabriolet, whose 3.8-liter twin-turbo flat-six develops 520 horsepower, driving the droptop to 60 miles per hour in 3.3 seconds. That's Porsche's claim, and we have a feeling it's a bit conservative. But if that's still not enough, the 911 Turbo S Cabriolet adds an extra 40 hp for a total of 560 to drop the benchmark acceleration run down to 3.1 seconds.
That makes the new topless Turbos 30 horses stronger and 0.2 seconds quicker than the respective models they replace, but the weight penalty involved with replacing a fixed roof with a folding one (and the necessary structural reinforcement) does make the new 911 Turbo Cabs a smidgen more lethargic than their contemporary coupe counterparts, which run the gauntlet in 3.2 and 2.9 seconds in standard Turbo and upgraded Turbo S specs, respectively. They only lose a single tick on the top speed, though, which clocks in at a follicle-tickling 195 mph in either spec. Otherwise the specifications are as identical as you might expect.

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.
