The designers bring the smart brand aesthetic to life with the smart forease, creating a light-heartedness that results from the unconventional approach typical of smart (ease by being unconventional): unconventional beauty, lightness and energy (energizing lightness) are achieved by reduction to the essential (clever reduction).

Like the concept vehicles "crossblade" (2001) and "forspeed" (2011) before it, the smart forease pays no heed to the convention that a car generally has a roof. It is open to the sun's rays and the wind, allowing its passengers to enjoy a liberated and pure driving experience. The shorter windscreen offers little resistance to the headwind.

The smart forease cleverly focuses on what is essential for urban driving enjoyment. Its manoeuvrability and relaxed openness exert a liberating and invigorating effect on the occupants. Safety comes courtesy of the two domes behind the seats.

The door handles, which are seamlessly recessed in the door, make for an elegant touch. The smart forease has a paint finish in effect-rich metallic-white. This offers a subtle contrast with the matt-silver Tridion cell and the brilliant "stream green" accents both inside and outside. Some of these are instantly noticeable, such as the contrasting green decorative seams on the upholstery, the green border around the media interface and the "stream green" contrast surfaces on the sides of the seats. Others become apparent at second glance from certain angles, such as the green honeycomb look inside the air vents plus further details on the headlamps and wheels.

The open vehicle concept produces a link between exterior and interior, the entire play of colour being at all times in evidence. The interior therefore contributes to the exterior impact of the vehicle. This is also reflected in technical details in the interior. A particular feature is the two round displays in place of centre air vents in the instrument panel - as if there were not already enough fresh air! The displays can be used, for example, to present content from the "ready to" app, which allows the driver to share their smart with friends or to monitor its functions. The speakers of the audio system, which provide a perfect sound for listening to music or making phone calls, are visibly integrated in the rear wall of the cockpit, emphasising the car's cool, playful character.
