For the last three months we've meticulously analysed the costs and energy consumption of our Tesla and compared them with a combustion car, a mid-range Octavia. We calculated the costs of the standard routes we drive every month:
- Commute to Julia's work: 4 times a month
- Trip to grandma's: 4 times a month
- Trips around town: 16 times a month
- Sightseeing trips: 2 times a month
Consumption and Cost Analysis
We compared fuel and energy consumption on different types of routes: in town, on national roads (DK) and on motorways. For the Tesla we calculated the actual cost of electricity, taking into account tax deductions, rebates and discounts. For the Octavia we looked at real fuel costs.
Cost Categories
Below are the detailed cost categories:
- Standard: The standard fuel price in our area (the real invoice cost)
- DKV: The cost after the DKV discount
- Tesla MMz: The cost of charging at the DC charger in Mińsk Mazowiecki
- Tesla Max: The cost per 1 kWh according to Tessie, including the GreenWay and EVklub.pl subscriptions
- Tesla Realnie (real-world): The Tesla Max cost, but based on actual energy use over three months, accounting for energy losses, parking, heating etc.
For longer routes we additionally analysed:
- Tesla Trasy (road trips): Costs when charging exclusively at DC chargers (higher costs).
Cost Chart
The first chart shows the costs for the categories above. In addition, in the second chart we compared the costs for our three most popular routes:
- Sopot
- Wrocław
- Szczyrk
Conclusions
The analysis shows that in everyday running costs the Tesla doesn't come out more expensive than the Octavia. It's not a huge difference, but considering we can't charge the Tesla from a home socket, the results are very satisfying.
Of course, you could wonder how much the costs would drop with home charging, but that option isn't available to us, so we focus on real-world data.
