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.

Porsche testing four-cylinder Boxster at the N?rburgring

Porsche recently introduced a four-cylinder version of the new Macan for markets outside of North America, carrying Zuffenhausen's first four-pot since the 968 ended its production run the better part of two decades ago. But you can bet the compact crossover won't be the only Porsche to get the four banger before all's said and done. These spy shots, we're told, are evidence of just that.
Spotted undergoing testing at the Nürburgring (where else), this modified Boxster, our spy photographers tell us, sounds more like a four-cylinder engine than the flat six that's powered (in displacements ranging from 2.5 liters to 3.4) every version of the little roadster since its introduction in 1996, the year after the last four-cylinder Porsche ended production.
The test mule is also wearing modified wheel arches and aerodynamic aids under the bumpers, front and rear. Just what they're doing there we're not sure, but we'll probably find out sooner or later.

Autocar pits Porsche 911 Turbo S against Formula 4 racer

There is a long-running argument among performance car fans: power vs. weight. In one corner you get cars generally with small engines making modest numbers but able to corner like they are telepathic, and in the other there are big thumping mills that are rocketships in a straight line but lumber in the turns. Autocar takes an interesting look this continuum in a recent video pitting a 552-hp Porsche 911 Turbo S against a 185-hp Formula 4 racecar. It hopes to find whether the Porsche's huge power advantage is enough to defeat the better grip and aero offered by the nimble racer.
There's no doubt that the Porsche is an utterly fantastic road car. The 911 Turbo looks mean with all of those intakes to suck in cool air, and it backs up the posture with huge amounts of grip available thanks to its all-wheel drive-system. However, at 3,538 pounds, it's a bit of a porker compared to the 1,135-pound Formula 4 car. The open-wheel car boasts just a 2.0-liter naturally aspirated four-cylinder from Ford and a six-speed sequential-manual gearbox, but it has loads of downforce to make up for it.
It shouldn't be a surprise that the formula car wins in the corners. After all, that's what it's made for. So do you think the massive horsepower superiority of the Porsche is enough to even the playing field? Scroll down to watch the video and find out, and even if you're not curious of the winner the 911 does some mean powerslides.
