2005 Rinspeed Senso

The Rinspeed Senso is a concept car designed by Swiss innovator Frank M. Rinderknecht with a focus on the emotional and psychological well-being of the driver. Introduced at the 2005 Geneva Motor Show, the Senso was developed in collaboration with Bayer MaterialScience, Hewlett-Packard, Sharp, and the University of Zurich. Rather than prioritize just performance or luxury, the Senso aimed to be the “most human-focused car ever created.”

The car monitors biometric data such as heart rate via a special wrist device and analyzes driving behavior using an onboard camera. This information is used to determine the driver’s mental state, after which the vehicle responds with a customized combination of interior lighting, music, and scents to relax or stimulate the driver accordingly. Visual and acoustic therapy are integrated with lighting effects (yellow-orange for stimulation, blue-violet for calming, and green for neutrality), specialized soundtracks, and aromatherapy.

Visually, the car adopts architectural styling cues with sharply defined lines and carbon fiber detailing. The driver sits in a central front seat with two passengers flanking from the rear—emphasizing the driver’s role as the focal point. The concept also retains high performance, using a modified Porsche powertrain that runs on environmentally friendly natural gas.
