2023 TESLA MODEL Y EFFICIENCY IS WORSE THAN MODEL 3 (BUT NOT BY MUCH!)

EV Channels Review

This video details a 1700km round trip road test between a 2023 Tesla Model 3 and a 2023 Tesla Model Y, both rear-wheel drive LFP variants, from Sydney to the Gold Coast. The primary focus is on comparing their real-world efficiency. The reviewer found that the Model 3 achieved a slightly better efficiency (145 Wh/km) compared to the Model Y (153 Wh/km) over the journey. This difference was attributed partly to the Model Y covering more distance for local travel on the Gold Coast, while the Model 3 remained parked. The video also includes an experiment on battery preconditioning for supercharging, suggesting that while it can be beneficial in cold conditions or with low state of charge, its impact is less significant in temperate weather and at higher states of charge, with the non-preconditioned Model 3 even catching up to and surpassing the Model Y's charging rate at times. The reviewer also noted the Model Y's projected range at 100% charge was 435km, while the Model 3's was 439km. Sentry mode drain was also discussed, showing a loss of approximately 7% per day. The reviewer's father-in-law, a first-time EV driver, found the Model 3 easy to drive over the extended journey.
