BYD Sealion 7 Comfort vs Nissan Qashqai e-POWER N-Connecta: the UK family cost and space comparison

This is a comparison of a genuinely visible Chinese EV, rather than an unlaunched export model. SMMT's September 2026 BEV model table lists 3,191 Sealion 7 registrations, third among the EVs shown. It is a model-line count; it does not tell us how many were Comfort trims or prove a complete Chinese-EV Top 10. SMMT's 2026 facts book lists 41,141 Qashqai registrations in 2025's lower-medium segment, making Nissan a meaningful familiar reference, though these different periods cannot be read as head-to-head sales. CathayEV's British GSC final window of 18 September-15 October contained 44 query rows with “sealion 7”, 422 impressions and no clicks. This is exposure of our pages, not national search volume. An existing UK pair result shows that buyers ask the question; its listed numbers are not used as specifications or a measured pair keyword volume. This gives the subject a B-level editorial signal, not a claim that the exact phrase is high volume.

The BYD UK specification identifies the rear-wheel-drive Comfort, not Design AWD or Excellence. Its rated 82.5-kWh Blade Battery feeds a 230-kW rear motor. The Nissan October 2026 UK brochure identifies e-POWER Gen3 205 PS N-Connecta: a front-wheel-drive hybrid with a 1.5-litre petrol generator and a small, 1.97-kWh usable battery. You cannot plug in the Nissan, and its petrol use cannot be compared with the BYD's electric WLTP range as though they were the same metric. Nissan's October price list gives the e-POWER N-Connecta an on-the-road reference price of £36,855. BYD's UK retail reference and current retailer listing give the Comfort £47,025 RRP. The reference-price difference is £10,170. Lookers also shows a lower stock/retailer cash figure, but it is conditional on the exact car, dealer and time. BYD national finance examples found online ended on 30 September and are not treated as current offers. Obtain both written, same-day on-the-road quotations with identical assumptions about paint, fees, finance and trade-in before comparing actual expenditure.

BYD publishes a 4,830-mm length, 1,925-mm body width excluding mirrors and 2,930-mm wheelbase. Nissan quotes 4,425 mm, 1,835 mm and 2,665 mm. The Sealion 7 is therefore 405 mm longer and 90 mm wider before mirrors. Put tape on the driveway or garage before assuming either will fit with doors open. Nissan also quotes 2,084 mm including mirrors; obtain the corresponding BYD mirror measurement for the exact UK vehicle before judging the narrowest point. The BYD has a quoted 520-L rear boot and 58-L front storage. Nissan says up to 504 L under the luggage cover, with boot space varying by configuration. A 16-L paper difference in the rear is too small to decide a pushchair purchase; the height of the boot opening, rear-seat angle, spare wheel or floor position may matter more. Bring the actual pram, rear-facing child seat and everyday bags to both dealers. The longer BYD wheelbase suggests more room to investigate, not a measured guarantee of better legroom or child-seat fit.

The Sealion 7 Comfort is quoted at 6.7 seconds 0-62 mph and 230 kW. Nissan's e-POWER specifications give 7.9 seconds in Standard mode or 7.6 in Sport mode from 0-62 mph; its motor drives the front wheels while the engine produces electricity. BYD wins the maker-quoted sprint. We have no shared-road test of throttle response, motorway noise, braking or ride quality, so those are test-drive questions. With the Nissan, a driver never has to plan a charger. It does, however, use petrol and need the servicing appropriate to an engine. With the BYD, routine home charging can replace filling-station visits, but a household without a suitable parking/charging arrangement should price its likely public charging before committing. Neither vehicle's instrument-panel range estimate is a substitute for a cold, loaded motorway test on the routes you actually take.

BYD quotes 300 miles combined WLTP for the Comfort, a 150-kW peak DC charge rate and about 32 minutes from 10% to 80% in favourable conditions. It has an 11-kW AC onboard charger, though a single-phase home installation typically supplies less than that. A 150-kW label is not a sustained power curve; temperature, charger output and state of charge affect the session. Plan a motorway stop with a margin rather than treating 300 miles as a guaranteed winter leg. Nissan quotes 4.3-4.5 L/100 km WLTP combined across e-POWER configurations and a 55-L petrol tank. It does not publish a plug-in charging time because there is no external charging port. A petrol stop is quicker than an EV charge stop, but the driver's actual stop duration and annual cost depend on the journey and prices. Do not convert a tank-plus-WLTP calculation into a guaranteed single-tank range.

Here is a transparent illustration, not a tariff quote or a forecast. Ten thousand miles is about 16,093 km. At Nissan's 4.3-4.5 L/100 km test figure, that is about 692-724 litres. If petrol were £1.45 per litre, it would cost roughly £1,004-£1,050 before real-world variation. For the BYD, a current retailer specification displays 3.1 miles/kWh WLTP; 10,000 ÷ 3.1 gives about 3,226 kWh on that test basis. At an assumed 25p/kWh, that is about £806. At 70p/kWh, it is about £2,258. Electricity losses, charging fees, seasonal efficiency, tyres and driving style can change both sides materially. Even the favourable home-electricity illustration saves only roughly £200-£244 a year against the stated petrol assumption before other costs. It would be misleading to say this automatically repays the £10,170 reference-price gap: finance interest, insurance, charger installation, servicing, tyres, tax, residual value and any real purchase discounts are unknown. Ask each dealer for an insurance group, tyre size/replacement quote and annual service estimate, then build a five-year calculation with your own energy prices and mileage. The value of quieter EV use is a preference, not a line on our unmeasured bill.

The UK BYD Comfort specification gives 750 kg braked; Nissan's October e-POWER technical page gives 770 kg. Other Sealion 7 trims or continental leaflets must not be substituted for this British Comfort. The 20-kg paper gap is too small to establish caravan suitability. Check the exact vehicle's certificate of conformity, gross train weight, approved towbar, nose weight, loaded trailer and driving licence. A caravan's quoted unladen mass is not its loaded mass, and passenger and luggage weights can reduce the remaining legal margin. Ask the selling dealer to confirm the installed towbar's own rating.

BYD's British Comfort equipment includes a rotating central display, panoramic roof, heated and ventilated front seats, heated rear seats and vehicle-to-load capability. Nissan's N-Connecta has 18-inch wheels and a 360-degree camera; a heat pack and panoramic roof are separately priced options in its October UK brochure. Confirm the exact stock build and try the infotainment, phone connection, child-seat access and controls before signing. A high-trim press car may have equipment the quoted car does not. Check whether the chosen wheel and roof configuration changes the homologated consumption or load-carrying figure.

Euro NCAP assessed the Sealion 7 and Qashqai under 2025 protocols; the Nissan listing includes right-hand-drive e-POWER 4x2. Both reports contain strengths and weaknesses. In the full-width frontal test, Euro NCAP described rear-passenger chest protection as weak for the BYD and marginal for the Nissan. A laboratory score is no substitute for installing your own restraint or confirming the ordered car's safety equipment. We do not declare a universal safety winner. Read the child-occupant and vulnerable-road-user sections too, and ask whether any post-test production changes affect the particular VIN being purchased.

BYD UK's warranty summary says six years/93,750 miles basic cover and eight years/125,000 miles for the battery, subject to model/VIN wording. Nissan UK lists three years/60,000 miles for a new passenger car, including e-POWER. Nissan's separate full-EV battery guarantee must not be applied to the Qashqai's hybrid buffer pack. Ask for the exact booklet and written local service prices, repair lead time and roadside terms. We have no matched reliability cohort for these exact versions. Confirm the service interval, any required dealer-network maintenance, parts availability and courtesy-car policy with both local workshops.

Choose a Sealion 7 Comfort test drive first if your family can charge at home, your parking space takes a 4.83-metre SUV, you want the larger footprint and richer heated-seat equipment, and the written purchase/insurance quote stays within budget. Check its real motorway consumption on your route and the actual tow certificate if a trailer matters. Choose a Qashqai e-POWER N-Connecta test drive first if you need a 405-mm shorter car, cannot charge conveniently, or the roughly £10,170 RRP gap dominates the decision. Check the actual N-Connecta options and whether the up-to-504-L boot holds your real load. Remember that e-POWER still burns petrol and is not a plug-in EV. If you are deciding principally on monthly cost, do not pick from the headline WLTP figures alone. Get two like-for-like signed quotations, home/public charging tariffs, insurance and maintenance quotes, then compare over the ownership period you expect. This is a source-checked UK desk analysis. It does not claim a road test, matched owner feedback, verified winter range or measured depreciation. ### Questions for the dealer 1. What is the exact registration/VIN and on-the-road cash price today, including colour, accessories, tax, discounts and finance conditions? 2. What are the approved WLTP and towing figures for this exact car, and which towbar is homologated? 3. Can we install our child seats and load our pushchair with the rear seats in normal position? 4. For the BYD, what would our actual home and public charging mix cost? For the Nissan, what service plan and petrol use should we budget at our mileage? 5. What are the written warranty exclusions, maintenance intervals and earliest repair appointment at our nearest workshop?
