As we reported earlier, McLaren P1 hyper car is currently on a tour of America, visiting the cities with the highest number of billionaires who don’t mind spending over a million dollars on a car. After New York and Chicago, the it has now landed in Beverly Hills for another private preview party.

And is the case with such events, new details emerge after each one revealing more facts about the production version of the car.

The P1 uses a carbon fiber tub like that of the McLaren 12C, which teams up with a carbon roof to make the passenger compartment. Most of the body panels are carbon as well, with aluminum used to make crumple zones. Other metal bits in this car are all made of titanium, which as far as metals go, is quite exotic. Thanks to this blend of lightweight materials, the P1 won’t be heavier than 1,300 kg.

McLaren is yet to reveal what kind of powertrain they’re going to put in the P1, but it is likely to be a more powerful version of the twin-turbo V8 found in the 12C, boosted with a clever KERS system, and/or an electric motor on the front axle. The combination of turbocharger and KERS will guarantee the P1 will match the output of its main rivals, Porsche 918 and Ferrari F150, both making well over 800 horsepower.

Production will be limited to 500 units worldwide, and the price is expected to start from $1.2 million before any personalization.
