Sealion 7 Premium vs 2026 Outlander PHEV XLS: NZ seven-seat and towing choice

Start with the Sealion 7 Premium if this is mainly a five-person household, you can charge overnight, your parking bay accepts a 1,925 mm-wide SUV and you do not need a braked trailer above 750 kg. It eliminates petrol stops and has the longer single-charge electric-trip proposition. Start with the Outlander PHEV XLS if occasional sixth and seventh passengers, all-wheel traction or a 1,600 kg published tow ceiling actually matter. Its petrol engine also makes an unplanned regional journey less dependent on a public plug. The Outlander is a plug-in hybrid, so failing to charge it still leaves the petrol and service systems to pay for; neither drivetrain wins every household.

September 2026 MIA registration figures reported locally put the Sealion 7 at 125 new registrations and 533 year to date. It was fifth in the displayed all-brand BEV table, useful evidence that New Zealand buyers are paying attention to this Chinese electric SUV. Those counts cover the model, not Premium sales, and are not a Chinese-only top-ten ranking. We did not find verified local search volume for this exact pair. The comparison instead answers a concrete question that a five-seat electric-versus-hybrid page cannot: is a seven-seat plug-in hybrid with a real tow rating worth its extra systems and charging routine? The current Outlander XLS is listed in New Zealand at a price close to the BYD, creating a plausible same-budget shortlist. This is selection type B: dated local model attention and a distinct buyer problem, with exact-pair demand unmeasured.

The Sealion 7 is 4,830 mm long, 1,925 mm wide and has a 2,930 mm wheelbase. The Outlander XLS dealer sheet gives 4,720 mm by 1,862 mm and a 2,704 mm wheelbase. BYD is 110 mm longer and 63 mm wider; this can affect a narrow garage more than the advertised seat count. The Mitsubishi's third row gives occasional seats, but ANCAP explicitly says the optional third row has no top tethers and does not recommend child-restraint installation there. Families with three young children should trial their exact restraint combination in the second row. With the third row erected, the Outlander's quoted boot is 217 L to the seatback; folded, it is 468 L behind row two. BYD quotes 500 L rear plus 58 L front. These figures come from manufacturer/dealer methods that are not confirmed identical; bring a pram and holiday bags rather than declaring a 32 L winner on paper.

The BYD Premium uses one rear motor rated 230 kW and 380 Nm; BYD claims 0-100 km/h in 6.7 seconds. Mitsubishi lists a 2.4-litre petrol engine, two electric motors, 221 kW combined system output and Super All Wheel Control four-wheel drive for the XLS. Comparing peak kW alone will not tell you how each feels with a full family or on wet gravel. A family needing regular steep, slippery access has a reason to test the Mitsubishi's 4WD, while the BYD's immediate electric response may appeal in commuting. These are hardware-based expectations, not a same-route road-test result. Drive both over the same coarse surface and low-speed parking manoeuvre; listen for tyre and engine noise and check visibility with your own child seats in place.

New Zealand's road-user charges apply to both cars. NZTA lists NZ$76 per 1,000 km for this light BEV type and NZ$38 per 1,000 km for a plug-in petrol hybrid. At 15,000 km the licence-distance components are NZ$1,140 for the BYD and NZ$570 for the Mitsubishi, before transaction fees. The Outlander also burns petrol when the battery is depleted or the engine is called upon; its 1.3 L/100 km converted combined laboratory figure assumes a test pattern and cannot be multiplied across a household's year as if every journey had a fresh charge. Both cars pay for electricity, with actual wall losses and public charging premiums. Build three scenarios from your own commute, home tariff, public-charge share and petrol receipts. Include insurance, tyres, scheduled servicing and resale uncertainty separately. Without these inputs, an annual saving or payback period would be invented.

For the exact variants, BYD's March 2026 sheet gives the Premium a 750 kg braked limit. The 1,500 kg number sometimes attached to a Sealion 7 belongs to the Performance grade and must not be borrowed. Mitsubishi's current XLS listing gives 1,600 kg braked and 750 kg unbraked, and publishes 2,865 kg gross vehicle mass and 4,465 kg gross combination mass. A 1,100 kg braked trailer exceeds the BYD Premium headline rating while fitting below the Mitsubishi headline rating, subject to the loaded car, towball, towbar and combination limits. Seven passengers and luggage can consume payload quickly. Get the VIN-specific handbook and accessory rating; weigh the actual trailer rather than using an empty brochure mass. Ask whether charging and regenerative behaviour change under towing, and plan materially lower electric range with a trailer.

BYD's local specification lists a 15.6-inch rotating central display, 10.25-inch driver display, heated and ventilated front seats, panoramic glass roof, Dynaudio audio and vehicle-to-load using the supplied adaptor. The Mitsubishi XLS dealer equipment list emphasises three-zone climate, heated front seats, wireless phone charging, wireless Apple CarPlay/Android Auto, an eight-speaker Yamaha system, rear-console USB-C and a 1,500 W vehicle-to-load outlet. It also lists an around-view monitor and 12.3-inch display. Check the showroom car for actual software and accessories: a rotating display is useful only if key controls remain easy on a bumpy road. Try climate adjustment, phone pairing, navigation, the reversing camera and row-three access with everyone seated. Power outlets are not a substitute for checking continuous-load limits in the manual.

ANCAP's 2025 Sealion 7 five-star result applies to all Australian and New Zealand variants, with 87% adult, 93% child, 76% vulnerable-road-user and 78% safety-assist scores. The current Outlander five-star result is a 2025 reassessment, with 85%, 84%, 79% and 70% respectively; the updated PHEV applicability begins with July 2025 production. Do not substitute the older Outlander rating for a newly built car. Confirm the XLS VIN falls under the updated specification and ask to see the relevant report. ANCAP explicitly notes that the optional third row lacks child-restraint top tethers, so extra seats are not an invitation to put young children back there. Both published ratings are useful evidence, but percentage differences alone are not a probability of injury in any individual crash. Fit your family's restraints in the second row before deciding.

BYD New Zealand advertises six years/150,000 km for the Sealion 7 vehicle and eight years/160,000 km for the traction battery, subject to exclusions, plus a separate roadside-assistance statement. Mitsubishi New Zealand states five years/130,000 km new-vehicle cover, ten years/160,000 km powertrain cover and eight years/160,000 km PHEV battery cover. Its Diamond Advantage page says conditions and non-transferability matter, while its battery page limits covered components to inside the drive-battery case. These are not identical products, and the ten-year label does not mean every component is covered for ten years. Compare the complete booklets, service intervals, battery-capacity wording, authorised-dealer distance, loan-car availability and tyre replacement cost. Request the VIN-specific schedule and a written first-five-year service estimate.

The Sealion 7's wide body and 750 kg braked tow cap are concrete limitations. It needs reliable charging to avoid regular public-charge planning, and an occasional regional trip needs a realistic CCS2 stop plan. The Outlander XLS offers seven seats and greater towing headroom but keeps both an internal-combustion maintenance schedule and an electricity bill; its charging connector is CHAdeMO for DC, so availability must be checked locally. Its displayed price is higher, and a seven-seat configuration leaves only 217 L quoted boot volume behind row three to the seatback. Neither car has been driven back-to-back here. Resale, insurance, charger installation and real loaded efficiency remain household-specific uncertainties. A claim that the PHEV uses only 1.3 L/100 km all year or that the BEV always does 482 km on the motorway would mislead.

For a five-person maximum household with an overnight plug, no heavy trailer and room for a 1,925 mm-wide body, the BYD gives the cleaner electric routine and a lower displayed starting number. For a family that occasionally carries six or seven older passengers, tows above 750 kg within loaded limits, or wants 4WD and petrol back-up on charger-sparse trips, the Outlander XLS is the more credible shortlist entry. If your third-row passengers need child seats, verify the restraints and anchors: ANCAP does not recommend installing them in the Outlander's third row. Before signing, collect same-day delivered quotes, calculate 15,000 km using NZ$76 versus NZ$38 RUC plus your own electricity and petrol use, and test identical luggage and parking conditions. Confirm the Mitsubishi VIN/build and correct 2026 range document because official and dealer pages show different electric-range figures.

Sources were checked on 28 October 2026. Only the New Zealand Premium and current listed XLS DX9XLS45 were used. September registrations establish attention for the Sealion 7 model, not a certified Chinese-only top-ten list or exact-pair search traffic. Price numbers are pre-on-road advertised figures rather than contracts. BYD's 482 km is WLTP; Mitsubishi's 103 km current dealer brochure figure is not asserted to be WLTP, and the brand overview's 84 km appears to describe an older specification. Petrol-plus-electric laboratory fuel consumption cannot be compared as one number with BEV range. ANCAP applicability is tied to build date. No independent same-route range, cabin, tow, charging or ride test is claimed. The conclusions are conditional and should be retested against VIN, household use and written dealer documentation.
