EPA Range, Claimed Range, Real-World Range
"Range" on an electric car hides three different numbers: the EPA's test-cycle estimate, the manufacturer's own claim, and what a reviewer measured on real roads. They are not interchangeable — and this site publishes only the first, with the fueleconomy.gov record ID printed beside every figure.
The three senses, defined
- EPA estimated range — the U.S. government test-cycle figure on fueleconomy.gov, per configuration. The only range this desk scores.
- Manufacturer-claimed range — the number in a maker's own materials, on its own test assumptions. Where it differs from the EPA figure, both get written down — never averaged.
- Real-world range — what an instrumented reviewer records on public roads. Car and Driver's range column is drawn from this world, and this desk restates its scores without re-judging them.
The 2026 evidence for keeping them separate
The conflicts are in the 2026 set, with record IDs. Car and Driver prints 420–480 miles for the Lucid Air; fueleconomy.gov rates the Air G Touring XR AWD on 19-inch wheels at 512 miles (record 49966). C&D prints 251–293 for the Porsche Taycan; the EPA's top configuration is 315 miles (record 50456). The reverse check: for the Model 3, C&D's printed 309–363 matches the EPA trim set exactly (309/314/321/346/363) — the magazine's figure is drawn from the same government well, just not for every trim. Configuration moves the number too: the i4 drops from 333 to 307 miles on bigger wheels (records 50188/50189), the CLA from 374 to 317 on regular tires (records 50031/50030).
The rule that follows is mechanical, and it is the whole reason this desk can publish range at all without a test fleet: EPA figure, configuration name, record ID — or the field is omitted.
FAQ
What is EPA estimated range?
It is the range figure produced by the U.S. EPA's test cycle and published on fueleconomy.gov, the Department of Energy database. It is the only range number this site publishes, and every figure on our ranking names its fueleconomy.gov vehicle record ID so it can be opened and checked.
Why do magazine range figures differ from EPA records?
Because printed figures are not always pulled for every configuration. In our 2026 set, Car and Driver prints 420–480 miles for the Lucid Air where the EPA record for the Air G Touring XR AWD (19-inch wheels) says 512, and 251–293 for the Porsche Taycan where the EPA tops out at 315. The same check vindicates the source on the Model 3: C&D prints 309–363 and the EPA trims land exactly on 309/314/321/346/363.
Does wheel or tire choice really change EPA range?
Yes, measurably. The EPA rates the BMW i4 eDrive40 Gran Coupe at 333 miles on 18-inch wheels and 307 on 19s (records 50188 and 50189). The Mercedes CLA250 Plus with EQ Technology is rated 374 miles on low-rolling-resistance tires and 317 on regular ones (records 50031 and 50030). This is why every range on this site names its configuration.
