BYD Dolphin Surf vs Dacia Spring: which small EV fits UK city life?
The verdict

Buy the BYD Dolphin Surf if
The Surf camera shown on the UK listing is important to you and the actual UK car has that equipment.
Buy the Dacia Spring if

The practical choice and the exact UK trims
Choose the Spring if its shorter body is the constraint; choose the Surf if a reversing camera matters, since BYD’s UK listing shows one as standard. The Spring is 289mm shorter, but length alone cannot tell you whether either car will fit or manoeuvre in your bay.
This comparison covers Dacia Spring Expression Electric 70 MY26 and BYD Dolphin Surf Active as listed in the UK. BYD’s Spain notice describes four- and five-seat Surf versions by market and trim; it does not confirm UK Active seating. Check the exact car’s seats and equipment.

China-side evidence
China context: what the official evidence does and does not show
BYD says Dolphin Surf is known in China as Seagull; the name does not establish identical UK equipment. BYD’s September 2026 Spain notice describes four- and five-seat versions by market and trim, which cannot confirm the UK Active layout.
The Renault Group’s September 2026 announcement concerns a newly announced Spring generation to be built in Slovenia; it does not establish a China-market counterpart for the UK Expression 70. The official sources reviewed provide no comparable China price or owner dataset for these UK variants, so no cross-market price or owner score is used.

| China vs UK spec difference | BYD Dolphin SurfKnown in China as Seagull; identical UK trim/equipment is not established. Spain MY26 shows market variation. | Dacia SpringNo China-market counterpart for UK Expression established. Renault’s new-generation notice says Slovenia production. |

Price: keep the two published bases separate
Dacia labels £11,990 as MRRP excluding metallic paint; BYD UK Media lists £18,650 OTR. These are different price bases, not a saving comparison. Neither figure is a personal quote. For a purchase decision, compare dated cash OTR quotes with paint, delivery and options itemised. If considering finance, keep deposit, monthly payment, term, mileage limits and optional final payment separate from the cash price. Confirm the price and included equipment against the exact vehicle you are offered. Ask for any eligible discount in writing.

| UK advertised price | Dacia Spring Expression£11,990 MRRP excluding metallic; not a buyer-specific OTR quote. | BYD Dolphin Surf Active£18,650 OTR on the UK Media listing; verify the price for the actual MY26 vehicle. |
Also noted
- Like-for-like price differenceNot calculated: the published bases differ and no matched quotes were obtained.
Parking: one is shorter, but neither has been tested in your bay
The Spring is 3,701mm long; the Surf is 3,990mm. That 289mm difference compares front-to-back length only, it does not establish fit or manoeuvrability. Dacia lists a 9.63m turning circle; no Surf figure was verified.
Width figures are not directly comparable: BYD gives 1,720mm without stating mirror position, while Dacia gives 1,767mm mirrors extended and 1,583mm folded. Both UK pages list rear sensors; BYD lists a standard rear camera, while Expression camera availability is unknown. Check the exact car, bay approach, door opening and cable access.
Range, charging and carrying: read the conditions
Dacia’s current UK technical table lists 140 miles WLTP combined. Its configurator read on 15 October 2026 showed 139 miles for Expression 70; the difference is unresolved. Neither figure is a winter-road result. BYD UK Media lists 137 miles WLTP combined for Surf Active; WLTP is not a promise of winter range.
Published DC charge times use different windows: Surf 10 to 80% in 30 minutes, Spring 20 to 80% in 29 minutes, so they cannot be ranked directly. Dacia lists up to 7kW AC and BYD 11kW AC. No same-condition charging test is available.
Dacia lists four seats and a 308-litre minimum boot. BYD’s UK page lists four seats and a 308-litre boot; because its MY26 notice describes market-specific layouts, confirm the exact UK car.

- WLTP to winter rangeNo winter or real-world comparative test performed; do not infer winter performance from published WLTP figures.
- Comparable DC charge rankingNot established: charge windows differ and no same-condition charging test was conducted.
Which one to shortlist
Shortlist the Spring if its shorter body helps with your front-to-back space and its equipment suits you. Shortlist the Surf if the UK-listed camera matters and the exact Active car has the seats and features you need. If neither decides it, inspect both in your bay and try your regular load. Check door opening and charging-cable access too. Before committing, compare the written cash OTR price and confirm the vehicle’s trim, model year, seat layout and camera equipment. Do not assume either listing matches every car in stock.
