Pages: 11 (including cover and credits). Sizes: A4 (210 × 297 mm) and US Letter (8.5 × 11 in), both PDFs included in one zip.

Printing: Print at 100% / actual size on A4 or US Letter. Inside pages use light backgrounds and print well in black and white; covers are dark, so start from page 2 to save ink.

Every fact is checked against named sources from the Lane Motor Museum, Octane (2026), WIRED (2017), Hagerty (2019), Agency Impianti and US patent 3,410,357 (checked 9 Nov 2026), and the sources are listed on the pack’s credits page. Things that can change, such as museum details and the car’s current speed and software version, are printed with that date. Where sources give different figures, each is shown with its source.
