Xcar considers the Porsche 911 GT3's PDK

Porsche ruffled some feathers when it unveiled the latest 911 GT3 a couple of years ago with a dual-clutch transmission instead of an old-school manual. The rationale was (and remains) that the PDK makes the enthusiast's Elfen faster than it would be with a stick. The purists scoffed, but Zuffenhausen held firm – and even did the same with the even more hardcore GT3 RS. In its latest video, the boys at Xcar set out to find out if the GT3 with its fancy automated gearbox is as good as the previous model (or as good as the current model could be) with a manual – and took in some of the track toy's other trickery while they were at it. Check out the video above to find out what conclusion they reached.

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.

Porsche planning something track-focused for Geneva [w/poll]

At the 2015 Geneva Motor Show next month, Porsche has confirmed that it will be showcasing two potentially exciting new models: One is the new Cayman GT4 we've already seen, but we don't know what the other will be just yet. All the German automaker is saying at the moment is that, "the second new model is another exceptional Porsche that sets new standards on the racetrack" and that "this vehicle confirms the sports car manufacturer's commitment to high performance sports cars that manage a very special link between everyday driving and motorsports." Given those two statements, we can probably rule out a crossover or sedan at one end of the spectrum or a purely competition-spec racer at the other. The likelihood is, then, that Porsche's surprise for Geneva will be the new 911 GT3 RS. But then it could be the Boxster-based convertible counterpart to the Cayman GT4 (whether dubbed Boxster GT4, Boxster Spyder or something else), or even a track-tuned version of the 918 Spyder to take on the McLaren P1 GTR and Ferrari FXX K. We'll just have to sit tight to find out, but you're welcome to read the press release below and tell us what you think Zuffenhausen has in store for us at the Swiss expo this year. Double world premiere at the Geneva International Motor Show 2015 Porsche shows two new high-performance cars for the first time Stuttgart. Dr. Ing. h.c. F. Porsche AG is celebrating the world premiere of two extreme sports cars at this year's Geneva International Motor Show. The new Cayman GT4 is the first high-performance sports car belonging to the GT family that is based on the mid-engine coupes. Clocking a lap time of seven minutes and 40 seconds on the North Loop of the Nurburgring, the new entry-level model makes a great debut. The second new model is another exceptional Porsche that sets new standards on the racetrack. The world premiere will take place during the Porsche press conference at the Palexpo Arena in Geneva at 11:30 (CET) on March 3, 2015. A live webcast will be available in German and English on: http://porsche.gomexlive.com/. This vehicle confirms the sports car manufacturer's commitment to high performance sports cars that manage to make a very special link between everyday driving and motorsports. These two premieres continue Porsche's tradition of presenting motorsport highlights at the spring car show on the shores of Lake Geneva. The 911 GT3, 918 Spyder and 919 Hybrid all celebrated their debuts in Geneva in recent years.
