More info from The Car Connection:Jeep is joining the Tokyo concept fray with the Treo - not a Handspring PDA/phone, but a three-seat ("two plus gear," also, according to Jeep) off-roader based on a compact-car chassis. A fuel-cell powerplant with zero emissions is anticipated by the design, as is an electric powertrain that would give the Treo all-wheel drive. The classic Jeep seven-slot grille is in evidence on the stubby nose; the rear seats fold flat to allow a third passenger or a mountain bike to ride in back. Stay tuned for more on Treo and more from the Tokyo show next week.
