Most of us would love to have McLaren’s Elva roadster tucked away in our garage, but with just 149 set to be produced – and costing more than £1.4m each – it’s safe to say it’s a model reserved for the lucky few.

But fear not as Lego has now joined forces with the British supercar maker to allow fans to build their own model – and at £17.99, for a fraction of the budget.

The firm says it will allow children and enthusiasts to ‘collect, build and explore one of the world’s most exclusive open top speedsters’. The 263-piece kit is said to feature a similar open cockpit, detailing and ‘air bubble’ as the real deal, despite measuring just 16cm long and 4cm tall.

The Lego model will also be accompanied by a McLaren driver minifigure, which is modelled on the sports car brand’s principal engineer Rachel Brown, who is in charge of the firm’s flagship Ultimate Series models, including the Senna GTR and the Elva.

Brown said: “It is amazing to have witnessed the Elva go from a boundary pushing concept drawing all the way to final vehicle production. It feels even more special now to see all of that hard work transformed into the Lego Speed Champions Elva model for us to share with children and fans across the world.

“Ever since I was a child I have dreamed of driving and testing cars and I still can’t believe that it’s a part of my job. I hope that it inspires other young people to follow their passions and pursue careers in the automotive or design and engineering industries. There are so many incredible opportunities.’’

The Elva is McLaren’s first true open-top roadster, with no ‘windscreen’ coming as standard, but rather an airflow system that can distribute the air away from the driver. Powered by an 814bhp twin-turbo V8, the Elva can reach 0-60mph in under three seconds and is McLaren’s lightest road car yet thanks to its carbon-fibre design.

The new Lego Elva follows on from a range of projects between the two firms, including the P1 hypercar, 720S supercar and track-ready Senna.
