The 750 km range is calculated based on the 19-inch wheels. Currently, the official offer includes 21-inch wheels. How much will the range decrease with the 21-inch wheels?

Can't they offer 20-inch like the 7x?

The range remains almost unchanged because the tire contact surface significantly affects the range, and the contact surfaces of 19 and 21 are the same.

The debate about the range difference is intense online, but it won't really affect real-life experience. The focus for 21-inch wheels should be on the cost of use. With a tire lifespan of 60,000-80,000 km, changing 21-inch tires is quite expensive compared to 19-inch ones.
