Sure. The average car gets 25 mpg, consuming ~1400 Wh/mi. A Tesla Model 3 uses ~240 Wh/mi. Thats almost a factor of 6 difference. You don't need quite as much energy when you are significantly more efficient and it is only getting more efficient as time goes on. Also add in the factor of recovering energy using regenerative braking which is impossible with ICE.
With a car, unless you have a specific use-case where you are driving 200+ miles a day, an EV is a no-brainer when it comes to efficiency in operating cost as well as emissions and overall energy use.
- asdfadsfgfdda 6y agoA Model 3 is smaller than the average car, it should be compared to something like a Honda Accord hybrid. Both have a similar cabin volume of ~100 ft^3. The fuel economy for a hybrid Accord is 48 mpg, or 760 Wh/mile. The Accord is also $10k cheaper, presumably that is because the Model 3 requires more materials and more embodied energy.

- dmos62 6y agoWhat are the energy requirements and emissions for just building the vehicle? I've heard rumours that it's non-negligible when considering total emissions that a car will have caused.
