The new McLaren P1 supercar will make its world debut tomorrow at the 2013 Geneva Motor Show, but if you were lucky enough to be in Geneva today you could have already seen the P1 displayed on the Geneva floor, much like the lucky and hard-working YouTube user, Shmee150, who managed to shoot this cool video.

As no surprise, the production version remains pretty much identical to the concept car we saw back in 2012. Under the hood, the P1 will combine a revised 3.8-liter twin-turbo V-8 engine with a low-weight, highly efficient electric motor. This hybrid system will deliver a total of 903 horsepower, which will sprint the P1 from 0 to 60 mph in just 3 seconds and up to a top speed electronically limited to 217 mph.

Full details on the new McLaren P1 will be revealed tomorrow during the car's official debut in Geneva.
