It should be able to go some 222 miles (357 km) on the highway, according to the EPA.
The 2021 Tesla Model Y Standard Range (rear-wheel drive) has recently received an official EPA range and efficiency rating listed on the EPA's website.
The manufacturer does not encourage customers to buy this version (it's not available in the online design studio and hasn't been since February), but there might be an option to order it through direct contact with Tesla (though some encountered difficulties with it).
Anyway, the "SR" version is the most efficient Model Y, as it has smaller battery and noticeably lower weight (single drive unit in the rear, instead of two probably helps a bit as well).
2021 Tesla Model Y Standard Range
The EPA Combined range value is 244 miles (393 km), but the more important EPA Highway range is 222.1 miles (357 km), which is over 27% less than 305.5 miles (492 km) than in the case of the Long Range AWD version.
The combined energy consumption is estimated at 129 MPGe: 261 Wh/mi (162 Wh/km).

2021 Tesla Model Y Standard Range VS Long Range AWD
For those interested in the comparison between the SR and LR versions, here we have a table that shows that the LR has an advantage of AWD, slightly better acceleration and more range, which comes at a cost of a 20% higher price (the last known value in the online design studio) and slightly higher energy consumption.
