McLaren-Honda MCL32 – The Launch

The lights dimmed and the MCL32 sat, under covers for the moment, waiting to reveal itself to the racing world. Simon Lazenby stepped out to address the gathered guests of McLaren and spoke fondly of the history surrounding the team.

Would the rumours of the orange livery be fulfilled?

The room became dark, the speakers boomed into life as snippets of past McLaren cars faded in and zipped out of focus, the excited tones of Murray Walker echoing around the centre to be replaced by the calm voice of Ayrton Senna.

The moment had arrived, the time was now.

Spinning majestically on a dark turntable the bright livery of the MCL32 was revealed for the first time and there was a collected gasp from McLaren fans around the world as the orange sparkled proudly under the studio lights.

Zak Brown strode proudly onto the stage and revealed that he had listened to those fans who wanted to see orange on the car, he understands the history of the team and he knows full well the passion of the fans who not only craved a hark back to a past full of glory but a history that is tinged with so many emotions.

The McLaren MCL32 was revealed to the world today and with it the hope that, finally, the past can become the present and the future can be as successful as the past.
