DOLPHIN 44.9 kWh Boost (MY24)

The BYD DOLPHIN 44.9 kWh Boost (MY24) is a 5-seat hatchback with front-wheel drive, sold new from 2023 to 2025, when it cost £27,195 in the UK, and now only available second-hand. It accelerates from 0 to 62 mph in 8.0 seconds, slower than 72% of the electric cars on sale in the UK. Its estimated real-world range is 165 miles (265 km) in a mix of town, country and motorway driving. That puts it among the shortest-range 10% of the 471 electric cars on sale in the UK, and 45th of 67 hatchbacks.

It uses around 3.7 mi/kWh (169 Wh/km), more efficient than the typical EV on sale (3.5 mi/kWh). The usable battery holds 44.9 kWh and on a rapid charger it averages 50 kW between 10% and 80%. With one 15-minute charging stop, it can cover an estimated 156 miles (251 km) at motorway speeds.

It has a heat pump, which helps preserve range in cold weather, and it does not support vehicle-to-load (V2L). The battery uses LFP chemistry, which manufacturers generally allow to be charged to 100% routinely.

Second-hand, a 2023 example is estimated at £10,300–£11,400 and a 2025 one at £15,500–£17,700, based on typical EV depreciation. After typical battery wear, a 2023 car should still manage about 155 miles of real-world range. These are estimates, not valuations: check real prices before you buy.
