A Quatro Rodas editor’s daily drive from Indaiatuba to São Paulo illustrates how highway speed affects the BYD Dolphin’s range. The route is 101 km each way. At a steady 120 km/h on the Bandeirantes highway, the car can average more than 18 kWh/100 km and reach the office with about 50% charge, prompting the driver to recharge before heading home.
