In order to support drivers in adopting a more fuel efficient driving style, there currently exists a range of fuel economy displays, providing drivers feedback on instantaneous and long-term fuel consumption. While these displays rely almost completely on visual components for conveying relevant information, we argue that there are significant benefits in using auditory interfaces for providing feedback while driving.

We review existing literature and discuss various design strategies for auditory displays that are applicable for supporting a fuel-efficient driving style. Exploring one of these design strategies, we furthermore introduce several prototypical sonification designs.
