Where the facts come from

Every factual claim on this site links to its source. This is the full list.

How we checked

Each fact was written in our own words alongside its source. Our build script stores the text of every source and, for each fact, checks that the key words and figures really appear in it. 66 of 66 checks passed when this site was last built (9 November 2026). Where we couldn’t find a named source saying something, we left it out. Where good sources disagree, we say so and give both.

Where sources differ

Engine power: the Lane Motor Museum says 80 hp; Octane says 76 bhp.
Flywheel: the Lane Motor Museum and Hagerty say 22 inches; Octane gives 508 mm and 113 kg. We give both and don’t pick one.
The famous claims (125 mph, 40-degree banked turns, “impossible to skid or flip”) were made at the time. We quote them as claims, next to what later sources say actually happened.
Some sources disagree on how the two seats were arranged and when old film of the car appeared online. We left those details out.
