Construction took 2,725 hours from start to finish, while the design and development took just over 2,000 hours. The car itself is built to an exact 1:1 specification in size, and includes a ton of bits from the actual Senna. Borrowed parts include a seat, steering wheel, pedals and infotainment system. Those in the driver's seat are able to operate the lights and play around with the big center infotainment screen. When you push the "start button," an engine simulation plays over the speakers to try and convince you that the twin-turbo V8 is actually behind you.
Real McLaren badges right off its cars are fitted anywhere you'd normally see one. Then the wheels and Pirelli tires from the Senna are mounted to the chassis. Getting in and out through the Lego dihedral doors is apparently a bit difficult, but they're removable to allow easy access to the seats. In total, the Lego Senna weighs a hefty 3,348 pounds, which McLaren says is 1,102 pounds more than the real Senna weighs. Keep in mind that this one doesn't even have an engine. It also took nine times longer to produce than a road-going McLaren Senna takes (which is 300 hours if you were wondering).
The details and structures to make this thing stick together are impressive, especially that huge wing hanging out the back. McLaren fitted some properly insane aero to the production Senna, and replicating the shapes and angles with Legos couldn't have been easy. Sadly, this one doesn't appear to have any real ability to drive at low speeds like the Chiron does with its electric motor. McLaren plans to show it off at car shows and events like the Goodwood Festival of Speed this summer.
