Real-world efficiency
2021 Polestar 2
Midsize Car · All-Wheel Drive · EPA 2.73 mi/kWh · EPA range 233 mi
Across 11 drives and 38 mi by 1 PlugLog driver, the 2021 Polestar 2 averaged 3.56 mi/kWh, 11% better than its EPA rating. That works out to about 259 mi of range.
From one driver so far: the numbers will firm up as more 2 drivers share.

Efficiency by outside temperature
Cold batteries and cabin heat cost range. Here's how much, for these drives.
- 50–68°F3.87 mi/kWh≈ 281 mi range · 6 drives
- 68–86°F3.16 mi/kWh≈ 229 mi range · 5 drives
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.
- Under 20 mph2.86 mi/kWh≈ 208 mi range · 4 drives
- 20–40 mph3.87 mi/kWh≈ 281 mi range · 7 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 usable battery, measured from shared drives (or estimated from the EPA figures), × the real efficiency. EPA ratings include charging losses, so vs EPA compares at the battery.

All EVsHow 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.
