By , editorUpdated How we work out these numbers

The EPA rates the 2027 Cadillac Optiq RWD at 317 miles combined and 32.1 kWh per 100 miles measured at the wall, which is 105 MPGe. City and highway split 354 and 281 miles, a 21 per cent drop on the highway.

Those figures come from the regulator and are used in the comparison tables, the efficiency and range rankings and the per-state charging costs on this site. The rest of the record is not yet sourced: the 10–80 per cent charging time has no published figure credited here, so this page does not state it. It will appear when it can be credited to a named source, and not before.

Range & efficiency

EPA, WLTP and CLTC are different tests, not different opinions about one number. They sit side by side here and are never converted into one another.

Peak power is a marketing number. The 10 to 80 percent time and the shape of the curve are what you actually wait through.

Safety & risk

Crash ratings come from the testing bodies. The battery safety score is our own composite and its formula is published on the methodology page.

Projected battery capacity

Projected straight-line from 2.7% a year — the published rate for this vehicle class, not a measurement of this car. Nobody releases per-model degradation data: the one fleet dataset large enough to matter anonymises the models. Capacity loss is driven as much by calendar age as by mileage, which is why it is reported per year rather than per kilometre. Real packs vary with climate, how long the car sits at a high state of charge, and how much of its charging is done at high-power DC.
