Why it matters

The Treo was shown at the 2003 Tokyo Motor Show as an urban Jeep concept aimed at young city buyers. Its two-plus-one layout put two seats at the front and one at the rear. Only one was built, so it is a single prototype rather than a production model.

02Production & history

Production

Every figure says what it counts.

What is countedFigureBasisStatus
Total model productiononly Treo in existence, per a 2003 press drive (Auto Express) 12 Surviving examples Independently researched
Total model productionsingle running concept (described as a one-off) 11 Factory production Independently researched

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

Auto Express drove the Treo two weeks after its unveiling at the 2003 Tokyo Motor Show. It was built on a truncated Wrangler platform with permanent four-wheel drive; its designer said it had not been tried off-road because it was a one-off.
