By , editorUpdated How we work out these numbers

The EPA rates the 2026 Audi Q4 45 e-tron at 288 miles combined and 29.4 kWh per 100 miles measured at the wall, which is 115 MPGe. City and highway split 311 and 260 miles, a 16 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: usable battery capacity 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.

Charging

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

Performance

Acceleration is quoted per market: manufacturers publish 0-60 mph in the US and 0-100 km/h in Europe, measured differently.

Cost of ownership

Prices are sourced separately per market. A US price and a European price are two different market prices, not one price at an exchange rate, so this site never converts between them.

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.

100% 90% 80% 70% 60% warranty floor 70% new yr 4 89.2% yr 8 78.4%

The battery warranty replaces the pack below 70% capacity. This projection reaches 78.4% at eight years.
