The 1:1 scale model was completed with help by museum visitors, who placed the final orange bricks on the Lego McLaren 720S on June 2.
The model is made of more than 280,000 Lego bricks to weigh in at 1,451kg compared to the road-going 720S at 1,283kg.
In order to produce an accurate representation of the second-generation of McLaren Super Series, McLaren Automotive worked closely with the only UK certified LEGO professional builders by providing extensive vehicle CAD data.
The model was built up around a steel frame, with a team of six working at one time for over 2,000 hours to build the car by hand.
In comparison, a real-world production 720S takes around 12 working days in the McLaren Production Centre to assemble.
Lego and McLaren fans will be able to customise their own mini Lego Speed Champions McLaren on an interactive iPad app next to the car.
The customisation app will offer the choice to add racing stripes, flames, chequered flags, license plates, backgrounds, and also add their name with an option to print a custom sticker of the car they have designed.
The Petersen’s Discovery Center located near the full scale car will host daily access to race ramps and build tables for museum attendees who want to build their own Lego Speed Champions race cars.
The McLaren 720S is available to order pre-assembled with a starting price of US$284,745 (RM1,132,000).
Smaller fans of the brand might be more interested in the 75880 Lego Speed Champions McLaren 720S miniature set, available in the Petersen Store for a fraction of the price.
