Porsche 918 RSR Concept

The Porsche 918 RSR concept car debuted at the 2011 North American International Auto Show was, not surprisingly, met with rave reviews and not a small amount of gawking. After a three-year hiatus from the Detroit venue, Porsche spared no expense or technological ingenuity with this new spin on the "traditional" hybrid, resulting in superior mechanical features.


The Porsche 918 RSR concept car was indeed worth the wait. And no one can accuse the designers of skimping on the bells and whistles either. Here's the specs:

Porsche more than delivered on its promise of a 500 plus hp version after its unveiling of the Spyder at the 2010 Geneva auto show. The 918 RSR combines a direct injection V8 with dual 75 kW electric motors to achieve a jaw-dropping 767hp capability. And if that's not enough to convince you that this is not your run-of-the mill racecar, the 10,300 rpm output is enough to seal the deal.

Unlike a typical hybrid, the RSR's electric motors fire the front half of the vehicle only and charge upon braking rather than relying on a battery pack, resulting in a light-weight, energy efficient power-source. Unlike the Spyder which was reportedly able to power itself for sixteen miles, the RSR uses the brake to charge for up to eight seconds, sacrificing longevity for the quick bursts of power necessary for a racecar. This design further advances the car's competitiveness on the track by decreasing the weight of the gasoline tank and lessening potential pit stops.

In the words of Porsche's chief designer, Michael Mauer, the 918 is not only a tribute to the Porsche 917 that took home the 24 Hours of Le Mans trophy in 1971(thus, the number 22 showcased on the car's hood as well as on its wing doors), but it is a testimony to the world that Porsche is still the leader in race-car designing. Considering that this two-seater with an on-board engine enhanced by flywheel technology boasting 36,000 rpms, who can disagree?

Not only is this car a work of mechanical and engineering genius, but it's not hard to look at either. The sleekly-designed racecar gleams of liquid blue chrome and is adorned with Porsche's signature orange stripes from front to back.

The dramatically angular spoiler and the sculpted wheel arches are the marks of a traditionally testosterone-driven racecar while the visible fan wheel on the top rear is evidence that there's really nothing traditional about what Porsche itself calls a laboratory experiment racecar. The brown leather interior conveys both simplicity and rugged masculinity, and the basic console and driver displays offset the complexity of the exposed engine.

There's no doubt this car will be both a beauty and a beast on the track, and who knows, depending on what Porsche has up its sleeve, we may just see a street version in the not-so-distant future.
