BYD Dolphin Surf
Leapmotor T03
The BYD Dolphin Surf costs £2,655 more than the Leapmotor T03. For that premium it adds 98 litres more boot space and a 1.6s quicker 0-62mph time. The Leapmotor T03 is not just cheaper - it also offers 27 miles more WLTP range. On EVcarsguide's combined category scores, the BYD Dolphin Surf comes out ahead overall.
The Leapmotor T03 is £2,655 cheaper to buy. Running costs are almost identical - about £176 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Leapmotor T03 comes out roughly £2,695 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
EVcarsguide estimates a real-world motorway range of about 87 miles for the BYD Dolphin Surf and 112 miles for the Leapmotor T03 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Leapmotor T03 goes roughly 25 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 30-36 minutes.
The Leapmotor T03 is the easier car for tight UK car parks: it is 68 mm narrower than the BYD Dolphin Surf. In a standard 2,400 mm bay that leaves about 748 mm of total clearance for the Leapmotor T03 and about 680 mm of total clearance for the BYD Dolphin Surf. The Leapmotor T03 also turns in a 0.7 m tighter circle, which helps with U-turns and multi-storey ramps.
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 90% battery health for the BYD Dolphin Surf and 90% for the Leapmotor T03. That is close enough that capacity loss should not decide between them. Both use LFP-type cells, which are happy charged to 100% every day.
