Efficiency by outside temperature

Cold batteries and cabin heat cost range. Here's how much, for these drives.

  • 68–86°F3.32 mi/kWh≈ 678 mi range · 1 drive
  • Above 86°F2.42 mi/kWh≈ 493 mi range · 1 drive

Longer bars go further on each kWh.

Efficiency by speed

Air resistance climbs quickly with speed. Here's what it costs, by each drive's average speed.

  • 20–40 mph2.81 mi/kWh≈ 574 mi range · 2 drives

Longer bars go further on each kWh.

Only drives from drivers who chose to share their efficiency data, with no names or locations. Efficiency is distance ÷ the energy each battery reported using, net of regen. Real-world range is the EPA range scaled by how the real efficiency compares. How it's measured

How it's measured

Real drives, straight from the battery.

EPA ratings come from a lab cycle. These come from the road: every drive shared by a PlugLog driver, recorded by the car itself.

Measured, not estimated

The PlugLog car app reads your battery's power many times a minute and checks it against the battery level. Efficiency is distance over the energy actually used, net of regen.

Shared on purpose

Drives count only if their driver turned on efficiency sharing, and then all of them do, so no one picks their best. No names, no routes, no locations: just how the EV did.

Every condition

Cold mornings, highway runs, short hops. Filter by the weather, speed and trip length to see the numbers that match how you'd drive.

PlugLog logs every drive and charge, works out what your EV really gets, and lets you share it to help the next buyer.
