RZ highway range at 120 km/h
NRCan's tests show the RZ 350e using 17% 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 RZ ranks #40 of 62 on this estimate.

RZ real-world range
Real-world range depends on speed, temperature, wheels and load. Mixed driving in mild weather usually lands near the rated 478 km. Sustained highway speeds pull it toward the 373 km estimate, and a cold highway trip can drop it further; see the RZ winter range. For trip planning, most drivers use between 10% and 80% (charging stops) or 100% (leaving home) of the battery, which is about 277 to 356 km of highway driving.
