How much real-world range loss should I expect on a used Model Y in Canada?
Average Tesla battery degradation after 80,000 km runs between 5% and 10% based on TeslaFi community data. A new Long Range Model Y is rated at 533 km; at 80,000 km expect 480-505 km in summer. In Canadian winter at -20°C, real-world range drops to roughly 60-65% of capacity — around 310-330 km. Pre-conditioning the battery via the app while still plugged into a Level 2 charger before heading to a Supercharger recovers 10-15% of that cold-weather penalty.
