Dragoman Sloflyr has acknowledged to me that the dimensions are actually correct.
I based the dimensions of my Bugatti model on the best information I have.
Wingspan: 8 m (26.4 ft) - to scale: 4 cm / 1.6 Inch
Length: 7.7 m (or 7.75 m) - 3.85 cm
You can find that information here, for example:
From the reconstruction project website

The length is also confirmed by an original Bugatti drawing in the book about the project (pages 32, 44).

I do not know, at the moment, what data sloflyr used as the base for his statement.
And I answered his personal message an hour after he posted it. It seems he overlooked that before he posted here.
