LeasePlan’s 2020 Car Cost Index is a comprehensive analysis of the costs of leasing and driving a subcompact to executive-size car (B1-E2 segments) in 18 European countries (Austria, Belgium, the Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Ireland, Italy, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom). The data is based on a four-year operational lease contract for corporates and assumes an annual mileage of 30,000 km. The analysis focuses on the average costs per month in each country. A true like-for-like comparison is important, but difficult due to so many possible vehicle combinations and fundamental differences between EVs and vehicles with internal combustion engines (ICEs). Therefore, to fairly assess the cost competitiveness of EVs compared to ICEs, the study strived to evaluate approximately the same balance of the same total cost of ownership (TCO) components for all types of vehicles, including fuel/energy, depreciation, taxes, insurance and maintenance. An EV is defined as ‘cost competitive’ when its TCO is within a 5% margin of the TCO of the most comparable ICE vehicle.
