What “Buildable” Means Here
  • VERIFIED only when a locked Studio .io, exported Wanted List XML, and matching instructions link are provided.
  • Otherwise it is DRAFT — a PRO design spec requiring Studio validation and a step-build pass.
  • Level 3 must be build-executable (micro-steps, gates, coordinates) — not an echo of Level 1.

When all three are present, the badge flips to VERIFIED and Level 4 wording is allowed to claim Studio-validated Real-Build.

Real-Build Update Notice: If you ever see a duplicate generator page, the newer one is likely the updated Real-Build logic version. Use the newest version unless it clearly says it is already current.

  • One-off 1966 mid-engine endurance prototype; V12 behind driver; never raced; crashed at MIRA in 1971, later rebuilt.
    • 
                  
  • Engine often cited as 5.0L quad-cam V12 (~502 bhp); ZF 5-speed; aluminum monocoque with engine as structural member concept.
    • 
                  
  • Commonly cited overall size: ~4,810 mm length, ~2,410 mm wheelbase, ~998 kg; top speed figures vary by source.
    • 
                

              


              

                
                

                  Studio validation is mandatory before claiming “Real-Build”:
                  collisions = none, legal clutch connections only, no stressed geometry, no floating parts, and a full step-build pass.
                

              


              

                
                

                  Import a Wanted List XML as a palette, lock colors to availability, then re-run substitutions.
                  Keep the final render pack faithful to the locked Studio model (same parts/colors/geometry; no invented seams).

BrickLink Studio Upgrade (VERIFIED vs DRAFT)


  

    Has .io? — VERIFIED path
    No .io? — DRAFT path + Starter Module Pack
  


  

    Upgrade any LEGO1 Build Pack into a Studio-compatible plans package. Copy your generator outputs for
    #3 and #4, then use the Upgrade Prompt below. If you provide a locked
    Studio .io, the result can be labeled VERIFIED; otherwise it must remain DRAFT.
