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 going all-turbo this year save for GT3 and GT3 RS

The coming Porsche 911 GT3 RS will represent another high-water mark for the brand, and another milestone. Its 500-or-so horsepower and extreme aero are predicted to lop more than five seconds off the 7:20 Nurburgring lap time of the current GT3, making it "comfortably less" than 7:20. Beyond that, its naturally-aspirated 3.8-liter will form the basis of the turbocharged engines going into the standard range of 911s later this year as 2016 models. That's right – if you're looking for a sub-GT3 911 that gulps its air without compressed assistance, then you've only got a few months to get a new one into your garage. Emissions regulations are the reason, of course, with Porsche's R&D chief Wolfgang Hatz saying that, "Every new model will have lower CO2 than before," and "if you look at euro per g/km, then it's turbo." We don't know what the engine lineup will look like, however; a few months ago Car reported that the base 911 would get a smaller-displacement version of the engine, while the S would stick with 3.8-liter displacement and jump to 520 horsepower, which is the same as the current Turbo. After that, Hatz said, "at the end of the decade electrification has to be the next huge step." That means a hybrid 911 is being cooked up somewhere. Yet even as the brand leaps into the new, there's a chance it could dip a toe back into the old: the 911 GT3 RS will launch with a PDK, but Hatz's team is considering adding the option of a seven-speed manual. Elsewhere in the range, the Cayman GT4 is being engineered by Porsche Motorsport as an entry-level racer, with more power than the current Cayman GTS to go with some serious weight loss. They are also developing a track-only model for privateers. The standard Boxster and Cayman will get turbocharged flat-four engines, but there'll be a sporty Boxster that also loses weight and gets more power than the 325-hp Boxster GTS. And that mid-level supercar that's been floating in the ether for years and supposedly sent to purgatory again just last November? It's on the way by 2020 "at the latest," and will use a version of the new V8 that will eventually go into the Cayenne and Panamera.

Chris Harris pits Aston GT12 vs 911 GT3 RS vs McLaren 650S

The Geneva Motor Show is never lacking in exciting performance machinery. And this year was no exception. Our eyes, like those of Chris Harris, were drawn by two hardcore, track-focused versions of existing sports cars. Both wore the name GT3, and now Harris has brought them together for a supercar shootout. And he's thrown one more in for good measure. Those natural rivals are the Aston Martin Vantage GT12 and Porsche 911 GT3 RS, the latter manufacturer having pressed the former to drop the GT3 name to which it claims exclusive domain. There's a great deal that separates them, of course: one's got a V12 up front, the other a flat-six way in the back. But what binds them together is a common approach of taking an existing model, stripping it down, and tightening everything up to make it more of a weapon than a grand tourer. What that means in the Aston's case is a rather high price tag, much higher than that of the Porsche. But scarce demand and speculation on the open market have left British customers, at least, paying as much for the GT3 RS as for the limited-edition Aston. And that takes both into proper supercar territory. So to show what else that kind of money can get you, Monkey has brought along a McLaren. Not the similarly track-focused 675LT, but the standard 650S... Spider, no less, and with worn hard rubber. So which one performs best on the road? Which clocks the fastest lap time on the track? And which gets Harris' vote? You'll have to watch the video for yourself to find out, but it's well worth the 25 minutes of your lunch break.
