BYD Dolphin Comfort vs Corsa Yes Electric: family space or a smaller UK hatch?
Dolphin Comfort is the first family-loading test; Corsa Yes Electric is the shorter-car shortlist. Both publish up to 265 miles WLTP, so battery size alone cannot decide this purchase.
The verdict
Dolphin Comfort is the first test drive when family loading and a longer-wheelbase hatch matter. Corsa Yes Electric is the stronger starting point when a shorter car suits parking and its grant-inclusive quote is available to you. Both publish up to 265 miles WLTP; neither earns a motorway charging victory from peak power or mismatched charge windows.
Buy the Dolphin if
You can use the Dolphin’s larger footprint, your family and luggage fit the actual car, and its complete cash quote justifies the premium over your eligible Corsa offer.
Buy the Corsa if
The Corsa’s shorter body fits your parking better, its actual rear-seat and boot space are sufficient, and the dealer confirms the selected 51 kWh Yes and grant basis.

Buy the named versions and compare the right price labels
This shortlist is BYD Dolphin Comfort with the 60.4 kWh battery and 150 kW motor against Vauxhall Corsa Yes Electric with the 51 kWh battery and 115 kW, 156 PS powertrain. Corsa's cheaper 50 kWh, 100 kW version is a different selection; its price and range cannot be combined with the 51 kWh car. Dolphin Surf is also a separate model. Check the configuration line on each written offer before comparing monthly payments, photographs or a general “from” price.
On 18 October, the Lookers advertisement describes a brand-new Dolphin Comfort available to order, showing £28,581.62 cash price and £30,230 RRP. Its offer terms run from 7 October to 31 December 2026. Availability and the final delivered cash quote still need confirmation; this is not proof that a particular colour is in stock. The Vauxhall MY26 datasheet lists £27,400 for the selected Yes powertrain, explicitly stating that displayed OTR RRP includes the applicable government electric-vehicle grant where eligible. Do not deduct a grant again. The displayed £1,181.62 difference is conditional on those labels and eligibility, not a universal saving. If eligibility or specification changes, compare the revised totals rather than keeping the old subtraction.
The extra footprint should earn its place in your driveway
BYD's currently linked UK specification gives Dolphin a 4,290 mm length and 2,700 mm wheelbase. Vauxhall's regular-body Corsa reference is 4,060 mm long with a 2,538 mm wheelbase; its separate GSE dimensions must not be substituted into Yes. Dolphin is therefore 230 mm longer on these references. That makes the physical choice meaningful even though both cars are sold as electric hatchbacks. A shorter car may be more convenient in a particular bay; a longer wheelbase is a reason to investigate family accommodation, not proof of measured rear legroom.
Take the household to both cars. Set the front seat for the usual driver, fit child seats, sit behind that driver and load the actual pushchair or holiday bags with the rear seats needed for passengers. The new BYD sheet quotes 364 litres with seats up, whereas older Dolphin material used a different number. We do not create a boot-volume victory by pairing that figure with an unverified Corsa value or an uncertain measurement method. The useful result is whether the load fits without compromising seating. Also try access with the doors restricted by a neighbouring parked car. That practical test can outweigh a modest purchase difference far more convincingly than a photo of an empty boot.
More battery capacity does not promise more quoted range
The current-linked Dolphin Comfort sheet gives 60.4 kWh and up to 265 miles combined WLTP range. Vauxhall gives a 51 kWh reference and up to 265 miles for the selected electric powertrain, with its warning that trim and packages affect the result. These manufacturer capacity labels are not a measurement of energy delivered at a charger. Their identical headline range is a useful reminder that battery size alone does not establish the distance a whole car can cover.
For a daily commute both may have ample margin, but a motorway or winter journey still needs its own plan. Speed, temperature, load and starting charge affect the usable distance. Neither quoted figure is our measured motorway range, and a car that starts a journey partly charged cannot be planned as though its whole laboratory distance remains available. Ask how the actual wheel and trim combination changes the quoted specification. Then identify a realistic charging stop and an alternative on your regular longer journey. This article has no matched winter consumption test from which to declare either car the better long-distance EV.

Use the updated Dolphin sheet, then match the charging windows
There is an important version trap. BYD's older UK media page still lists 88 kW DC for Comfort, while the specification currently linked by the UK model page is the 2025-version document showing 110 kW. We followed that live specification link and read the actual table. It quotes 36 minutes for 10 to 80% and 26 minutes for 30 to 80%. The 26-minute figure is not a 10 to 80% claim. A search result pointing at an obsolete download path is not a reason to reuse an older number for a new order.
Vauxhall lists a 100 kW DC maximum, but the datasheet contains different charging-window entries across its electric variants. We have not established a common test of these exact two cars under equivalent conditions, so there is no stop-time winner. A 110 kW peak is not a constant session average or a promise of a shorter break. Both publish 11 kW AC capability; achieving that rate needs a suitable supply, and a typical lower-powered home installation cannot deliver it merely because the car supports it. For an overnight user, verify the energy you need to replace and the installation capacity. For frequent motorway travel, compare applicable windows and real route access rather than the largest number in the specification table.
Value is the delivered car plus the routine it supports
Get two itemised cash quotations with the same assumptions: paint, delivery, registration, required accessories, grant treatment and any trade-in handled separately. A dealership saving, finance deposit contribution and government grant are different items. The Dolphin's listed cash price is not its PCP monthly payment. Corsa's grant-inclusive figure cannot be compared with a second grant subtracted. If one quote changes, update the comparison before making a purchase decision. Insurance should also be quoted for the actual vehicle rather than inferred from another battery version.
For two EVs, the larger running-cost question may be where you charge rather than which badge is on the bonnet. As a sensitivity example only, suppose a car takes 18 kWh from the wall per 100 km. At an assumed £0.25/kWh it costs £4.50 per 100 km; at £0.75 it costs £13.50. Over 10,000 km that difference is £900. These are not measured consumptions for either car, current tariff quotations or a total ownership forecast. They show why a workable cheap charging routine can matter more than a small specification difference. Installation, servicing, tyres, finance and resale still belong in the full budget. No promised fuel-cost or depreciation victory is implied here.
China-side evidence
Match the UK version before using overseas reports
The UK source changes we found are themselves a warning against transferring owner evidence by model name alone. Dolphin Comfort's currently linked specification differs from the older UK media material on charging, and the selected Corsa is the 51 kWh Yes rather than the 50 kWh car or GSE. An overseas report has to identify battery, model version, equipment and relevant software before it can support a conclusion about the vehicle in your quotation. Shared branding is not enough to resolve those details.
No matched Chinese owner cohort, complaint-rate denominator or recall comparison for these precise UK configurations was verified for this draft. We therefore do not add a numerical reliability ranking, an overseas winter-distance claim or a prediction of UK repair experience. The source-supported rows below set the local version boundary. They are not presented as China owner findings. Ask for the exact ordered specification and current UK warranty terms, especially if a review or dealer database describes a different charging configuration. A documented uncertainty is more useful than a confident conclusion borrowed from a car you are not buying.
Owner reports, complaint records and recall notices from the Chinese market, each with the source and the date we read it. Sample sizes are small; read them as signals, not survey results.
The decision to make after the test drives
This is UK buying analysis from current manufacturer and dealer material checked on 18 October 2026. The linked BYD PDF was visually checked because its extracted text loses some numerals; the real table, not a garbled extraction, supplies its figures. We have not performed a back-to-back drive, a luggage measurement or an actual charging test. Grant eligibility, delivery and exact insurance remain matters for the written offers. Company-car users should obtain the current P11D and tax-year calculation instead of treating either retail cash figure as the taxable value.
Start with Dolphin Comfort if family use is the reason for moving beyond the smallest electric hatches. Keep it on the shortlist when the loading test works and the confirmed premium buys space you will use. Start with Corsa Yes Electric if a shorter car is valuable and it comfortably carries your usual passengers and bags. If both fit equally well, let the eligible delivered quote, insurance and charging routine decide. If neither passes the household test, equal WLTP headlines are not a reason to force a choice. The useful answer is the car that meets the real task, with the exact battery and conditions you agreed to buy.
