LEGO® Technic reveal: 42123 McLaren Senna GTR

Posted by Admin

Just revealed, and available 1 January 2021, LEGO® Technic 42123 McLaren Senna GTR contains 830 parts and will cost 49,99€/ US$49.99/ £44.99/ AU$89.99/ CA$69.99. The age mark is 10+, and the model is 32cm (12in.) long. We will be reviewing this set just as soon as it is released, but in the meantime we thought we'd share some of the new elements we spotted in the official images.

This will be the first McLaren supercar to be recreated in LEGO Technic form and follows the Speed Champions versions of the McLaren P1™, the 720S in 2017 and the McLaren Senna in 2019. It features a V8 engine with moving pistons, opening dihedral doors and the iconic rear spoiler. And a lot of stickers.

New parts in LEGO® Technic reveal: 42123 McLaren Senna GTR 

Just like this happy chappie, the New E team have spotted a new mould which looks to be a Technic Panel 3x2. 

There are at least 2 in Bright Blue/ Blue and 2 in Black. We reckon, if connected to the existing 5x2 panel at the axle connection, it will continue the same shape, allowing for extensions and so on. Extremely exciting! 

There are also several recolours of existing parts into Blue. Here are the ones we spotted, can you find any more? 

  • Technic Panel Car Mudguard Arched 3x9x2 (42531) which comes printed
  • Hose Soft Axle 11 modules long (32199)
  • Left and Right Technic Panel Fairings 11x3 (64681 & 64393)
  • Technic Pin Connector Hub with 2 Axles (27940)

That last one is very exciting as this piece has only ever come in Dark Bluish Gray in the past.

“Recreating a car that is so extreme to the core as the McLaren Senna GTR with LEGO Technic gave us an incredibly interesting challenge” says Uwe Wabra, Senior Designer, LEGO Technic. “This track car is not like any road car I’ve worked on before. It’s got some unique details, like its silhouettes and the awesome rear spoiler, which differentiates the building experience from others. Just like the incredible engineers at McLaren do when designing their supercars, we really pushed things to the max so the resulting model perfectly honours the art form that is the McLaren Senna GTR.”

Robert Melville, Design Director McLaren Automotive, comments: “The team responsible for the design of the McLaren Senna GTR worked incredibly closely with their design counterparts at the LEGO Group to capture the extreme looks, excitement and essence of such an incredible supercar for LEGO Technic builders. Just like the real thing, the LEGO model is packed full of incredible details from the rear spoiler to the moving pistons in the V8 engine to the dihedral doors meaning that we’re as proud of the model as we are of the real car.”

  1. Huge disappointment LEGO should be able to do better than this. won't was my money on this atrocity. "Brick On"

    1. It's Lego, not a scale model. Why do you hate it so much?

  2. I wrote this on another site and sums up my feelings:

    I wish the Technic line would dial back on the panels. They’re trying too hard to model the surfaces and rather than make it look good it just looks awkward, especially when contrasted to the Creator large vehicles.

    IMO they should go back to a more “structural” look with fewer panels, more exposed mechanicals, and use the part count to include more technic features. Yes, use a few flex axles and a wheel arch here or there to give the general impression of the car, but if you’re trying to really accurately represent the real thing just admit that it needs to use more system bricks to accomplish that.
