Efficiency can cut EV prices by $5k, charging costs by nearly a third (www.greencarreports.com)

In a new white paper, the group notes that boosting efficiency allows for smaller battery sizes, which in turn cuts costs. Most EVs average 2.5 miles per kwh, according to the paper, but the Tesla Model Y averages 3.5 miles per kwh. That's a 40% increase which, assuming similar range, allows for a 40% reduction in battery size that's worth up to $4,800 in cost savings, the ACEEE reasons.

Does the Tesla model Y actually get 3.5 miles per kwh though?

Since the current EV production focus is on either sport or large models, it should be obvious that they are going to be less efficient, just like ICE sports and large model vehicles. The white paper is correct that smaller and more economically designed models would be far more efficient, but obvious conclusion is obvious.

A german car club tested the (european) model Y and got this result

  • The 2021 test vehicle had an efficiency of approximately 2.75 miles/kWh (22.6 kwh/100km)

  • The recently tested model has an efficiency of approximately 2.93 miles/kWh (21.2 kwh/100km)

  • The promised efficiency is approximately 3.68 miles/kWh (16.9 kwh/100km)
