Visit “Random Useless Info” and browse a variety of information including a study on the fuel economy of a 1996 BMW 318ti in dependence of underlying average or constant speed. The study clearly illustrates the negative influence of stop-and-go traffic on fuel economy and revealed the optimal constant speed for lowest fuel consumption of the vehicle: 40 miles/h (64 km/h).

On his blog “La Prius à Côté”, Stéphane Côté published two comprehensive studies done with his Toyota Prius 2010 (Prius III). First, he assessed the accuracy of the vehicle’s fuel gauge by comparison of the average (tank-wise) fuel consumption displayed by the trip computer (L/100 km) with the real value calculated after each complete fill-up. Based on 54 data pairs, he demonstrates that the fuel sensor of the Prius underestimated volumes in a temperature-dependent manner by approx. 8% on average. The second study focused on the factors that affect the fuel consumption of the vehicle. Analysis was done on defined routes and revealed that, compared to parameters like the type of tires, driving style, the vehicle’s weight or average speed, the outside temperature had by far the highest impact on achieved fuel economy. All findings are interpreted and discussed in light of the physical factors involved.
