New McLaren to debut on Saturday

(GMM) McLaren on Friday unveiled the MP4-24; the car bearing the number 1 with which Lewis Hamilton will defend his world championship.

The low-key launch event took place at the Mercedes-powered team's pristine Woking headquarters, but the first example of the new model is already at the Portimao circuit in Portugal.

Ahead of next week's group test in the Algarve region, McLaren has booked a private session at the circuit on Saturday, where Spanish test driver Pedro de la Rosa will give the 2009 car its track debut.
