2016 Porsche 911 GT3 RS First Drive [w/video]

Imagine a regular Porsche 911 GT3 in your garage, parked next to a brand-new, no-options Boxster. Now imagine your garage with just a 911 GT3 RS inside. From a cost standpoint, you could have either for roughly the same amount of money. Trying to figure out if the RS goodies are worth the $50,000 over a standard 911 GT3 – roughly the price of that no-frills Boxster – might drive you mad. We're trying to suss this out at 120 miles per hour on the long downhill back straight at Road Atlanta. It's pouring. Rivulets of water are streaming across the track. Ahead, in a 911 Turbo leading the pack, is Le Mans- and Daytona-winning driver David Donohue. He's helpfully warned us to avoid nipping the curbing, since that's where water pools. Hydroplaning could end someone's day. Through the blinding spray, Donohue mercifully has reduced the pace. There's enough speed to evaluate what the GT3 RS does well, which is essentially everything. There's also enough time to figure out what sort of sports car this is. Horsepower swells to an even 500 and torque to 338 pound-feet – bumps of 25 hp and 14 lb-ft over the GT3. As is fitting and proper for the traditional sports car par excellence, at the top of the large and expensive 911 heap is the GT3. While the base is shaken by the encroachment of turbocharging on basic 911 models, the summit is, like mountain air, all-natural. The GT3 was subject to a beyond-galling recall due to faulty con-rods with a penchant for ventilating crankcases and starting catastrophic fires, but storms crash upon every peak. Progress is inevitable for German engineers. The GT3 RS is the 911 reforged in those embarrassing fires. The GT3 itself was a false summit, but the RS is the real deal. Underneath the very purple bodywork, this is a lither and more athletic thing than the already superb GT3. Lightweighting is accomplished with a healthy dose of carbon fiber on the engine cover and the frunk. The roof, with a slick-looking depressed slash running longitudinally, is made of magnesium. That serves to lower the center of gravity, Porsche assures us. Even the rear silencer is made of titanium. In total, the RS is 22 pounds lighter than the GT3 it's based on – seemingly small gains considering all the exotic materials, but less so considering what's been added back. The RS is also more powerful, thanks to a 200cc displacement increase.

Porsche Cayman GT4 speeds back into view

We're all familiar with the succession of numbers that follow the letters GT on a hard-core Porsche 911: the GT1 that was Stuttgart's Le Mans contender in the late 90s, the GT2 that packs turbochargers but without the Turbo's all-wheel drive and excess weight, and the naturally aspirated GT3 that's the enthusiast's choice. But a GT4? That's something new, and exactly what Porsche has in store.
Spied testing in Germany once again is the upcoming GT4 version of the Porsche Cayman, set to supersede the existing GTS and take the place of the previous Cayman R at the top of Porsche's junior sports car range. This latest batch of spy shots doesn't show us much more than the last crop, but gives us a much clearer view at what promises to be the most hardcore Cayman to date.
As you can see, the Cayman GT4 packs a much more aggressive aero kit and rolling stock than any version we've seen to date. It's got a lip spoiler, big air dam and GT3-style vent in front of the hood, deep air scoops along the flanks, a set of spindly alloys packing oversized brakes, a diffuser with twin central exhaust tips around back and a rear wing that's likely to be replaced with a sleeker unit before the GT4 reaches production.

Magnus Walker and Alex Ross stop by Leno's garage with their 997 GT2

The market is littered with Porsche 911 tuners, with names like 9ff, Gemballa and TechArt leading the field. Seldom do any two ever collaborate on a joint project, but that's just the kind of match that was made at Jay Leno's Garage. That's where Alex Ross of SharkWerks and restomodder Magnus Walker first met, sparking a collaboration that yielded the car you see here. And fittingly, they've brought it back to the garage to show off what resulted. Though Walker usually deals with older Elfens, this time he applied his eye for style on a more contemporary 2008 997 GT2, decking it out with grey stripes, orange bumpers, gold wheels and decals and a tartan-upholstered interior. He left the mechanical bits to Ross and company, who dropped the suspension and increased output to 650 horsepower at the wheels (775 at the crank), surpassing the stock GT2 and even the later GT2 RS. The result is pretty hard-core and old-school, but you'll want to watch the video above to see for yourself.
