Fig. 5From: Understanding the origins and variability of the fuel consumption gap: lessons learned from laboratory tests and a real-driving campaignVariation in FC gap grouped by drivers and sorted by mean values (from lowest to highest value). The box represents the 1st and 3rd quartile; line is the median; red dot is the mean; whiskers represent 1.5*IQR; and dots values below or higher than 1.5*IQR (red dashed line represents the official NEDC-based FC gap (0%); blue dashed line represents the WLTP FC gap; and green dashed line represents the PEMS FC gap)Back to article page
