The McLaren P1 has been sighted at the recent McLaren MP4-28 launch on Thursday 31 January.

The supercar was making its public debut as the MP4-28 Formula One car got a run-out ahead of the new season.

The P1 was driven by former title winner Jenson Button, who put the wrapped car through its paces.

The car first appeared at the Paris Motor Show in September 2012, and will be fully unveiled in production form at the Geneva Motor Show in March.

The McLaren P1 that was driven on the day was one of the manufacturer's experimental prototype versions of the hybrid.

Other cars featured at the launch included a phenomenal number of cars from its rich championship-winning heritage.

Appearing at the event were famous McLarens including the 1970s M8D sportscar, and other models such as the McLaren 12C Spider.

Also at the event were Emerson Fittipaldi's iconic 1974 M23, Ayrton Senna's dominant 1988 MP4/4, the 1995 Le Mans-winning F1 GTR, Mika Hakkinen's MP4-13 car from 1998, and the most recent championship winning car to wear the McLaren badge, the MP4-23 from 2008.

The P1 outshone them all though, with its powerful turbocharged V8 engine heard from miles around.

The 12C Spider was driven by McLaren's newest F1 driver Sergio Perez. It's understood that both Button and Perez will have some input into the P1's development.

McLaren will be celebrating its 50th birthday on 2 September 2013, which is when P1 customers will accept deliveries of the car.

The car has been hailed as the successor to the McLaren F1 hypercar, with the manufacturer aiming to make the P1 the best driver's car in the world both on road and on track.

P1 owners looking to compare car insurance prices for the P1 will likely find the car sitting in higher insurance categories when the car is released.
