The driver of a Ferrari 458 Spider decided to "stalk" a McLaren P1 on its way back to the McLaren Technology Center.

The McLaren P1 is probably one of the most spied cars ever, and there are enough reasons for that. All will be revealed in early March at the 2013 Geneva Motor Show. The F1 successor has already been confirmed with a 916 HP output from its hybrid powertrain.

The carbon fiber encapsulated interior cabin has been partially exposed a while ago, showing two steering wheel-mounted buttons. One of them is for Drag Reduction System (DRS) while the other one is labeled IPAS – Instant Power Assist System. Once the driver presses the IPAS button, the P1's electric motor will be activated and will provide the supercar with the throttle response of a normally-aspirated engine.
