Porsche digitally dissects its 918 Spyder for your viewing pleasure

At this point, you'd think we'd know all there is to know about the 2015 Porsche 918 Spyder - except what it's like to drive - but Porsche has released a new video giving us a more in-depth look at its new plug-in hypercar all the same. The animated video gives us numerous cutaway looks at the 918 Spyder while giving a visual demonstration of the car's four hybrid driving modes.
Though nowhere near as exciting as watching the 918 blast around the Nürburgring in record time, this new video is nonetheless both interesting and informative. Scroll down to watch the video yourself, and be sure to check out our live gallery of the production version of the car along with a stock gallery.

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.

Vintage-ish Porsche 911 buying guide

Harry Metcalfe is always great at showing viewers the intricate details of the vehicles in his collection as part of the Harry's Garage series. This time he's helping out future buyers by explaining what to look for when purchasing a classic and slightly more modern Porsche 911. His examples for this lesson are two absolute beauties that are about to cross the block from Silverstone Auctions in the UK: a 1972 2.4 S and a 1991 964-chassis RS Clubsport. The '72 in creamy white here epitomizes the look of early 911s. The coupe is handsome, purposeful, and fairly compact by modern standards. According to Metcalfe, when looking at one, don't worry about a wobbly gearshift. Apparently, they're all like that, even ones as well cared for as this example. As with any used car purchase, he recommends trying to get as many service records as you can. It's just good to know as much about the vehicle's life as possible before throwing down any cash. Where the '72 911 shows the more gentlemanly side of the brand, the '91 RS Clubsport is Porsche proving the company's performance credentials. Metcalfe slightly dings the switch to an aftermarket air filter here, but overall it's hard to find a major fault. These cars were essentially road-going racers in this trim. The engineers in Zuffenhausen chopped out as much weight as possible and then fitted Recaro racing buckets and a roll cage. This thing was meant clock as many laps around the 'Ring as the driver could stand.
