Q4 e-tron highway range and real-world range

At a steady 120 km/h, we estimate the Audi Q4 e-tron 45 e-tron covers about 358 km on a full charge, versus 463 km rated.

Q4 e-tron highway range at 120 km/h

NRCan's tests show the 45 e-tron using 20% more energy on the highway than in the city, so highway range is lower the combined rating. NRCan's highway cycle averages well under 100 km/h, so we take its highway figure and reduce it by 15% for 120 km/h. The Q4 e-tron ranks #47 of 62 on this estimate.

Q4 e-tron real-world range

Real-world range depends on speed, temperature, wheels and load. Mixed driving in mild weather usually lands near the rated 463 km. Sustained highway speeds pull it toward the 358 km estimate, and a cold highway trip can drop it further; see the Q4 e-tron winter range. For trip planning, most drivers use between 10% and 80% (charging stops) or 100% (leaving home) of the battery, which is about 266 to 341 km of highway driving.
