You talking about a specific car? Most times that's marketing mumbo-jumbo that just means another gear.

Ford Contour has a button you press that keeps it out from 4th gear. This does EXACTLY the same thing as taking your Honda & putting the shift lever into D3.

The days are long gone when top gear in any transmission was direct-drive. Manual transmissions with separate OD gears (old british cars, '76 Volvos...) are something else entirely.
