Which One’s Heavier; The Full Size LEGO Or The Real McLaren Senna?

This full-scale McLaren Senna is built almost entirely out of LEGO bricks, taking specialist assemblers almost 5,000 hours to complete, as it’s comprised of nearly half a million separate components.

Intriguingly, the LEGO Senna is somewhat of a heavyweight, tipping the scales at 1700kg (3,747 pounds), or about 500kg (1,102 pounds) more than the real-life McLaren Senna that sold out as soon as it was announced in 2017.

According to McLaren, this is their most realistic LEGO car ever. While you may not be able to get it out on the road, people can actually sit down behind the wheel, operate the working lights and push the start button on the roof, which will prompt the car to play a simulation of the engine coming to life.

In total, 467,854 individual LEGO elements were used here, which is almost 200,000 more bricks than what was needed to build the LEGO 720S from two years ago. Teams of up to 10 assemblers needed 2,725 hours to click all the pieces together – in this time, McLaren could have hand-assembled nine real Sennas. Including design and development, it took 4,935 hours to create this full-size LEGO hypercar.

This also happens to be the first LEGO McLaren to feature interior parts from the real car, such as the lightweight carbon fiber driver’s seat, steering wheel and pedals. Also present are actual McLaren badges, while the wheels and Pirelli tires are the same as on the real car. As for the dihedral doors, they are removable so as to allow people easy access to the cabin.

The LEGO-built Senna is finished to replicate a Victory Grey finish with contrasting orange highlights, similar to the 15 cm-long, 219-piece Senna LEGO Speed Champions edition that went on sale earlier this year.

McLaren will bring the full-size LEGO Senna to various events this year, including the Goodwood Festival of Speed in July.
