The Lancia Dialogos concept car made its debut at the Turin Motor Show in 1998, anticipating the future Thesis in its lines. At the heart of the project was the innovative concept of a "biodynamic car": a place to live, not just a vehicle to drive, a space where matter and technology offered wellbeing as well as aesthetic pleasure. The result was an interior billed as "a healthy bubble", to be inhabited while enjoying a stress-free drive. The Dialogos prototype's style reinterpreted the Lancia tradition in a more contemporary key, with a high front, long bonnet, inverted wedge profile, soft curves, rounded edges and assertive personality. Internally the car is spacious and comfortable, providing exceptional comfort and practicality on board, also thanks to its Top Climate System: this detects external temperature, humidity and pollution conditions, and creates an ideal climate inside. The Lancia Dialogos could rise or sink down, depending on the height of the driver, and its seats rotated and moved outwards to help passengers enter. Once occupied, the seats retracted, the doors closed automatically and the car adapted to the driver's habits: to drive on the right or left and to modify climate settings and vary the diffusion and intensity of illumination and sound. The Dialogos offered an interior with clean shapes and comfortable spaces, but could then produce screens and keyboards, mini-bar, table and document compartments on command. Instead of the traditional dashboard and instrument display, it featured a large panel formed by three liquid crystal display monitors: one reserved to showing performance information to the driver, a second, near the passenger, dedicated to navigation and comfort, and a third in the centre showing images from the rear-view camera.
