Some lucky bloke (Shmee150 on YouTube) was luck enough to come across the McLaren P1 out in the wild while riding around in a Ferrari 458 Spider. What are the chances of that! This comes on the Heels of McLarens announcement that it will be powered by a 903 horsepower Hybrid V8.

What do those buttons do?
That little blue button to the right and the red to the left, may be the reason that the interior of the P1 was not shown to the public at earlier previews(unless your Jay Leno perhaps). The DRS is used for the Drag Reduction System and the IPAS (IPAS on the pun that could be used here) is the Instant Power assist.
PAS and DRS optimise performance and throttle response
The power available via the petrol engine and electric motor is further enhanced on the McLaren P1™ through two steering wheel-mounted buttons which activate the DRS (Drag Reduction System) and IPAS (Instant Power Assist System).
The Drag Reduction System used on the McLaren P1™ is a technology similar to that employed on Formula 1 cars. Speed is increased by reducing the amount of drag on the rear wing and, where the MP4-28 has a moveable flap on the rear wing, the McLaren P1™ has a wing that reduces in angle to lower drag by 23%. The system immediately deactivates when the button is released, or if the driver touches the brake pedal.
IPAS is designed to deliver power rapidly for high performance acceleration, and provides 179PS of instant additional power. In developing the IPAS technology for the McLaren P1™, power delivery was prioritised over energy storage. This is achieved through a groundbreaking, lightweight battery pack, which offers greater power density than any other automotive battery pack on sale today.
Look for more detials at the 2013 Geneva Motor Show in March and Nice job to Shmee150 on the P1 video.
