The Tesla Model 3 averages around 6km per kWh or 165 Wh/km. For local driving below 50 km/h with windows open but no air con it goes as low as 120 Wh/km or 8km per kWh, but the bulk of our kilometres are on the open road at 110km/h with the windows closed and climate control on. At speeds over 70km/h the drag from open windows has a greater impact on energy consumption than climate control.
On the Synergy Midday Saver, 1kWh costs roughly 6¢, so in the middle of Winter when I have to charge from the grid, as long as I do it between 9:00 am and 3:00 pm, the Tesla Model 3 costs on average 1¢ per km to drive. In the Summer, when I use my own solar panels to charge the Tesla, the cost per km is zero.
The reported range on my Tesla Model 3 is 420km. This is lower than the range in the brochure, I presume because the brochure is based on an urban model, while the range reported by the car’s computer is based on our actual usage. If I go beyond that range, the economics switch, because the Synergy EV network chargers cost around 60¢ per kWh, and cost of driving the Tesla Model 3 is now 10¢/km.
The RAV4 hybrid averages 6 litres per 100km. If petrol costs $1.67/litre, that is an average cost of 10¢/km. The RAV4 hybrid is the opposite of the Tesla in that short journeys, especially on cold days with the automatic choke hard on, fuel consumption is 3 or 4 times the average, so the cost per km might range between 30-40¢/km.
So if you are mostly taking short journeys, the Tesla Model 3 wins hands down over the Hybrid. But if you are planning a trip round Australia, the RAV4 hybrid is the go. It is a bigger vehicle, and fits more luggage. You won’t have to look for DC charging stations, and waste up to an hour at a time sitting there. And the cost per km is roughly the same as the EV.
