BYD ATTO 3

Owners love

Watch out for

Owner tips
- Expect about 200 miles in mixed driving and plan longer trips around rapid chargers.
- Get insurance quotes from several providers before you buy.
Tesla Model Y
Long Range Dual Motor
Owners love
- Supercharger network makes long-distance travel easy, with little charging anxiety and simple trip planning
- Spacious and practical: a big boot plus a front boot suits families and road trips
- Efficient, so running costs are low, especially on a cheap overnight home tariff
Watch out for
- Firm suspension: many owners find the ride harsh on rough roads, especially on larger wheels
- Several owners report headlights aimed too high after software updates, dazzling oncoming drivers, and re-aim them in the service menu
- Insurance quotes run well above comparable EVs, owners report
Owner tips
- Choose 19-inch wheels over 21-inch if ride comfort matters
- Set tyre pressures to the label on the door pillar; some cars arrive over-inflated, which makes the ride harsher
