Total cost of ownership: How electric vehicles and ICE vehicles compare

Electric vehicles (EVs) are becoming more and more popular. No longer limited to tech-savvy early adopters, they are capturing the attention of a far wider audience and rapidly changing the face of the overall automotive landscape.

Total cost of ownership: How electric vehicles and ICE vehicles compare There are two main reasons for this: first, the introduction of many new EV models in recent years, and second, the growing affordability of electric driving. In fact, Ayvens’ Car Cost Index 2021 shows that in many European countries, EVs are even cheaper to drive than traditional internal combustion engine (ICE) vehicles (*source CCI 2021). But how much does it cost to drive an EV compared to a similar ICE model, and where exactly can the differences be seen? In this blog, we compare the total cost of ownership (TCO) between EVs and ICE vehicles.

Taken as an overall figure, on average across the 22 countries in scope, the TCOs for the Volkswagen Golf and the Volkswagen ID.3 are similar. However, there are clear differences in the individual cost elements, as illustrated in the figure below. The cost elements of the Golf are set as the baseline, with the ID.3 cost elements compared against them. This method highlights the differences between EVs and ICE vehicles.

In 2021, the price of electricity (EU/kWh) and the price of petrol (EU/litres) rose. Naturally, an increase in this cost element of the TCO will result in an increase in the overall TCO. However, the effect of an energy price increase on an EV versus the same energy price increase on an ICE vehicle is different, since electricity costs are a smaller part of the TCO than fuel costs are. For the Volkswagen ID.3, energy accounts for 11% of the TCO while, for the Volkswagen Golf, energy accounts for 22% of the TCO. See the figure below for an illustration.

An increase in the price of electricity therefore has a different impact from an increase in the price of petrol/diesel. For example, when the price of both electricity and fuel increases by 50%, this results in a TCO increase of 6% for the Volkswagen ID.3, but a TCO increase of 11% for the Volkswagen Golf. This shows that the ID.3 is more resilient to energy price fluctuations than the Golf. In addition, an EV can be charged from renewable energy sources – so if you have solar panels on your roof and (partly) charge your car with electricity from those panels, you are even less affected by price fluctuations.

Conclusion

This comparison shows the TCO of a Volkswagen ID.3 is on average lower than that of a Volkswagen Golf. Clearly, from a cost perspective, EVs are a suitable alternative to ICE vehicles in car policies, and there are few reasons to avoid them. Most of the countries included in this study show scenarios in which an EV is the lower-cost option (see CCI 2021*). We also see that, in general, a longer lease duration and higher mileage will produce greater cost advantages for the EV compared to the ICE vehicle, both because of the lower running costs (primarily road taxes and fuel) and because of the (higher) investment value that can be spread over a longer period.

The analysis also shows differences in the individual cost elements when comparing ICE vehicles to EVs. One of the most significant factors is fuel and electricity costs, which come out in favour of EVs and which should therefore always be included in a fair TCO comparison. Furthermore, not only are EVs are less sensitive to energy price fluctuations but they can also be charged (at least in part) by renewable energy sources. **
