Electric car: here is the savings you will make driving at 110 km/h on the motorway!

news hardware Electric car: here is the savings you will make driving at 110 km/h on the motorway!

Driving long trips in electric cars can be stressful. Autonomy is usually the number one criticism we make of them. But can driving at 110 km/h save energy, but also money?

Driving 800 km on the highway in a Tesla Model 3, is it easy?

Electric cars are extremely practical for daily journeys of less than 100 km. But when you overcome this distance, the stress begins to grow to go further. Results, we changed our way of driving, We slowed down and crossed our fingers to make it to the end.

However, the solution adopted by many is to drive at 110 km/h instead of 130 km/h on the highway. We imagine saving money and potentially even saving loading time in Superchargers. When is it really?

In a distance of 800 km between Pau and Paris, we actually save money. Especially with the recent price increase on Tesla Superchargers. On the other hand, in terms of total time, 800 km is an intermediate stage that does not save time. Worse, it increases travel time.

The Tesla Model 3 in front of the highway

About the classic Tesla Model 3, therefore not long-range, with a 61 kWh battery, the manufacturer announces Autonomy of 491 km in WLTP standard. So should we be able to complete a full ride on a single charge on the go? Nope..

In reality, the motorway consumes more, compared to mixed consumption (motorway/city), on which the autonomy of the WLTP standard is based. According to Tesla, it is possible to drive at 12 kWh/100 km. Actually on the road we turn between 16 and 18 kWh/100 km.

In practice, on a 800 km trip, with a 100% charged car, it is necessary to recharge four times while driving at 130 km/h, even if it is possible to do so with only three recharges. This will have taken a little over an hour of Supercharger time. The cost, with Tesla’s price increase, is 77 euros total.

Passing at 110 km/h, consumption drops to 16 kWh/100 km and allows you to stop calmly 3 times, for a total time of 50 minutes. Rate level we drop to a total of 60 euros

In terms of travel time, saving 10 minutes will not be enough to exceed 130 km/h. When driving at the maximum speed limit, it takes about 8h15 versus 8h40 driving at 110 km/h.

What to remember:

tesla model 3
Cost of the trip at 110 km/h €60
Cost of the trip at 130 km/h €77
Travel time at 110 km/h 8:40 a.m.
Travel time at 130 km/h 8:15 a.m.
Average fuel consumption at 110 km/h 16kWh/100km
Average fuel consumption at 130 km/h 18.2kWh/100km

In the end, for people who want to go as fast as possible, driving at 130 km/h is the best option. On the other hand, to save money and electricity, driving at 110 km/h is more eco-responsible. Increasing travel time is only 5% at the end.
