Traffic Light Thought - Windy Corollas?

When they named the Toyota Corolla II Windy I wonder which definition they were thinking of ;

• Characterised by or abounding in wind: a windy night.
• Open to the wind; unsheltered: a windy terrace.
• Resembling the wind in speed, force, or variability: a windy dash homeward.
• Lacking substance; empty: windy promises.
• Given to or characterised by wearisome verbosity: a windy speaker.
• Flatulent.
