Machine learning vehicle fuel efficiency prediction. [PDF]

open access: yesSci Rep
To address the challenges associated with fuel consumption in vehicles with low fuel efficiency, several factors must be recognized. Identifying the key factors of fuel efficiency prediction is crucial for making accurate decisions. Therefore, we propose a comprehensive framework that uses machine learning to predict fuel efficiency by integrating ...

Framing car fuel efficiency: linearity heuristic for fuel consumption and fuel-efficiency ratings [PDF]

open access: yesEnergy Efficiency, 2014
People are sensitive to the way information on fuel efficiency is conveyed. When the fuel efficiency of cars is framed in terms of fuel per distance (FPD; e.g. l/100 km), instead of distance per units of fuel (DPF; e.g. km/l), people have a more accurate perception of potential fuel savings.
