One very special McLaren 720S is set to make an appearance at Goodwood in the U.K., swapping its usual aluminium and carbon fibre structure for bright orange Lego bricks. Following on from the launch of the 'Lego Speed Champions McLaren 720S (75880)' miniature set, McLaren's all new supercar will be fully realised in Lego form at the Festival of Speed. But there's a twist. The 1:1 scale model will arrive at the Goodwood stand incomplete.

In order to finish the build, visitors to the McLaren stand will need to place orange McLaren bricks in designated parts of the car, with the 720S reaching completion by the Sunday at the end of the Festival of Speed.

Just preparing the car for Goodwood has required more than 267,300 Lego bricks, with McLaren fans visiting the stand expected to add over 12,700 to completely finish the build.

The end result will be a full-size Lego 720S weighing in at no less than 1.6 tonnes, more than the road-going 720S's 1,283kg lightest dry weight. In order to produce such an accurate representation of the 720S, McLaren Automotive worked closely with the Speed Champions Lego team based in Billund, Denmark, providing in-depth vehicle computer-aided design data so that the model could be fully realised.

The model was built-up around a steel frame, with a team of six working for over 2,000 hours to build the car by hand. For comparison, a real-world production 720S takes around 12 working days in the McLaren Production Centre to assemble. Also featured on the Lego 720S build is the all new Pirelli P Zero Corsa tyre used in its road-going equivalent, complete with silver 'Pirelli Colour Edition' graphics.
