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.

I think one of the coolest bits about Aptera’s approach is how you don’t really need to worry as much about cooling. If you trust their 100Wh/mi estimate, that’s an average draw of around 6kW compared to 15kW in even a Model 3.

Assume 90% efficiency (conservative), and its the difference between dissipating 600W of heat (midrange computer) vs 1.5kW (hairdryer). Passive cooling options especially around the batteries become more viable at that point.

I'd still want active cooling on the batteries for charging in hot areas or with fast charging
