Optiq highway range and real-world range

At a steady 120 km/h, we estimate the Cadillac Optiq FWD covers about 383 km on a full charge, versus 510 km rated.

Optiq highway range at 120 km/h

NRCan's tests show the FWD using 26% 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 Optiq ranks #33 of 62 on this estimate.

Optiq real-world range

Real-world range depends on speed, temperature, wheels and load. Mixed driving in mild weather usually lands near the rated 510 km. Sustained highway speeds pull it toward the 383 km estimate, and a cold highway trip can drop it further; see the Optiq winter range. For trip planning, most drivers use between 10% and 80% (charging stops) or 100% (leaving home) of the battery, which is about 284 to 365 km of highway driving.
