[5] Distinctive body features include front styling dominated by a large grille, and the absence of side central pillars with the rear doors opening backwards, to evoke the design of the Lancia Aurelia saloon of the 1950s.

Other interior features includes: a steering wheel and instrument panel located at the centre for ease of access but that can slide on either side depending on the prevailing driving direction; 2 screens fitted in the back of the front seats; a tactile thin film of softwood bonded to a layer of resin and foam for the dashboard and some other areas; a personal electronic key, known as the "Ego Card", which allows the car to adapt to an individual's needs associated with seat position, multi-zone climate control settings, steering-wheel and pedal position; automatically opening driver's door upon approaching the car.

Mechanically, although not equipped with an engine, the Diàlogos is said to feature an active differential and adjustable drive-torque distribution to both axles as well as advanced multilink suspensions.

The rear suspension too uses a virtual pitch center such that, when riding over an obstacle, the wheel moves back to reduce interference transmitted to the body.
