McLaren is pretty much claiming the McLaren P1 as the greatest engineering marvel the world has ever seen. The official performance specs of the highly anticipated McLaren P1 have been unveiled and the Woking, England-based manufacturer is convinced that the ultra-advanced hybrid supercar possesses unmatched levels of engineering in every conceivable shape or form. 

To begin, the McLaren P1 hybrid supercar is powered by a 3.8 liter twin turbo V8 engine mated to a hybrid powertrain produces 903 hp. McLaren promises 0-to-100 km/h (62 mph) will take 2.8 seconds. In fact, 0-to-200 km/h (124 mph) will only take 6.8 seconds. Finally, 0-to 300 km/h (186 mph) will take just 16.5 seconds, a staggering 5.5 seconds quicker to the benchmark than the McLaren F1, its iconic predecessor. 

The McLaren P1 is just as efficient as it is powerful. Thanks to its remarkable hybrid system, the 217 mph P1 averages a U.S. fuel economy of 28.3 mpg. What's more, CO2 emissions is just 194 g/km. On pure-electric, the P1 offers a modest range of only 6.8 miles.

Strong, bespoke Akebono carbon ceramic brake disks stop the McLaren P1 from 82 mph in just 99 feet, or just a third of what it would take an average car. 

Despite the McLaren P1's awe-inspiring numbers and figures, it is the Porsche 918 Spyder that has been the darling of the Nurburgring. Last month, Porsche published the its official 918 Spyder along with an official video demonstrating its record-breaking 6 minute 57 second lap.

The slightly larger 4.6 liter V8 engine in the Porsche 918 Spyder is also mated to a hybrid-electric powertrain. At 608-hp, the V8's 132 hp-per-liter output makes it the most powerful naturally aspirated engine that Porsche has ever created. Combined, the V8 hybrid supercar makes 887 hp.

Despite the lower objective performance figures, Porsche is notorious for understating its specs. When Porsche shared its record breaking lap, motorsports blog Axis of Oversteer shared this:  "Last week, the car internets got very excited about a Mclaren P1 timed at 7:01 around the Nürburgring. Not as excited was Mclaren who did not publicize the fact. Why?"

Of course, the recent activity at McLaren in Germany paints a clear picture-- the British supercar company will not stop until it thoroughly dethrones the Porsche 918 Spyder. Now, a video from earlier today suggests that the McLaren P1 completed the infamous Nurburgring in just 6 minutes 47 seconds, an unreal 10 seconds quicker than the Porsche 918 Spyder.

Only 375 examples of the McLaren P1 hybrid supercar will be built until mid-2015. The first McLaren rolled off the line at the end of September.
