Launched in January 2000 as the second model in the company's new SUW (Smart Utility Wagon) lineup, the Dion was developed to a "Smart Design" and "Ecology Conscious" theme. Although it was a minivan seating seven in three rows of seats in a compact body, the Dion provided generous interior space with its 2705mm wheelbase and flat floor design and with its optimized hip point and low side sills offered excellent occupant access. The second row used separate seats on long-travel slides and fitted with a walk-in mechanism, thereby facilitating access to third row seats even with a child safety seat fitted. The third row of seats can be folded down and stowed under the floor to create a roomy luggage space with a flat floor. And this row of seats can be flipped over to face rearwards. The Dion used a Smart Shift automatic transmission lever mounted on the steering column that operated like a floor shifter. All models used a powertrain mating the environmentally-friendly 2.0L GDI engine to the INVECS-II 4-speed automatic transmission. A medium facelift in May 2002 gave the Dion a more expressive front fascia design and fitted with the INVECS-III CVT transmission.
