Trends in global fuel economy of new vehicles: 2005 - 2022

This data contains information on the fuel economy of new light-duty vehicle sales in major automotive markets and underpins the report - Trends in the global vehicle fleet 2023: managing the SUV shift and the EV transition. This report is the 2023 installment of the Global Fuel Economy Initiative (https://www.globalfueleconomy.org/) which, among other things, tracks progress in the efficiency of the global vehicle fleet. 

Yearly vehicle sales are defined by segment (small car, medium car, large car, small SUV, large SUV, Light Commercial Vehicle) and powertrain ( internal combustion engine, mild hybrid, hybrid, plug-in hybrid, battery electric, fuel cell hydrogen). For each combination of segment and powertrain the data contains information on sales, average weight (kg), average footprint (m2), and average specific energy consumption (lge/100 km). The data was obtained from a set of sources and processed to gain the best possible estimate of global trends in energy consumption for light duty vehicles. More information on the methodologies underpinning the data analysis can be found in the report.

  • pivots_country, pivots_powertrain, pivots_segment: intermediate step 
  • Powertrain: registrations, specific fuel consumption, weight and footprint  by powertrain
  • Segment: registrations, specific fuel consumption, weight and footprint  by segment
  • Graphs: Includes plots of the above two tabs, contains a country selector in I2
• sdmx.zip
  • Data structures and data in SDMX-ML format, containing exactly the same information as supplementary_information_GFEI2023_TDC.xlsx, converted using the code at https://github.com/transport-data/gfei-2023

Nota Bene: Older versions of Excel might encounter issues with titles in graphs, that is likely caused by the CONCAT function not being availble - substituting the CONCAT function with CONCATENATE should solve the problem.
