The short answer
- Lowest price right now: the Deepal New S07 at ฿1,099,000. Its reference price is ฿1,219,000, which is actually ฿19,100 above the Sealion 7 Premium. The saving depends on the October campaign.
- Bigger battery, more power, longer vehicle warranty, AWD option: the Sealion 7. The Premium has a 82.5 kWh battery against the S07's 68.8 kWh, and the Performance and Ultimate add all-wheel drive.
- Where it is closer than it looks: both include a home charger with installation in October offers, and the S07 claims fast DC charging (30–80% in 15 minutes, a manufacturer claim).
- What nobody can tell you yet: a fair head-to-head efficiency test, resale value, and parts and repair times. We found no controlled Thai comparison, and we say so below.
Side-by-side specs (Thai-market versions)
We compare the current Deepal New S07 (68.8 kWh LFP) against all three Sealion 7 variants. Older S07 versions (66.8 kWh and 79.97 kWh NMC) were sold earlier at ฿1,399,000 and ฿1,499,000; we could not confirm remaining new stock, so they are not compared here.

*Campaign prices: BYD (Rêver) 2 October 2026; Deepal (Changan) campaign valid 1–31 October 2026. Sealion 7 power, battery, range and AC figures were checked on Rêver's Thai model page. Deepal figures come from Changan's leaflet and Thai launch reports and were not all re-checked on the manufacturer site. Range is NEDC, which is generous; see the efficiency section. "Reported" means a media figure, not a manufacturer-confirmed one.
What the price gap really buys
- You give up: 13.7 kWh of battery (68.8 vs 82.5), about 82 km of NEDC range (485 vs 567), about 55 PS, and one year plus 30,000 km of vehicle warranty
- You give up: AC speed on paper (about 7 kW reported vs 11 kW)
- You gain: 8 years of roadside assistance (vs 5), a large frunk (125 L reported), a swivelling 15.6-inch screen, AR-HUD and a claimed faster DC charge
- Home charger and installation are included in both offers; the allowance covers 15 m of work for Deepal and 10 m for BYD
- Performance: all-wheel drive, 390 kW, 4.5 s to 100 km/h, same 82.5 kWh battery (NEDC range drops to 542 km), about 115 kg heavier
- Ultimate: adds a 91.3 kWh battery, 600 km NEDC, 230 kW DC peak and a 520 L boot; 800V architecture is reported but not confirmed by a Thai primary source
- Ultimate's charger and installation is a ฿10,000 purchase option, not free
Charging at home and on the road
At home, the car sets the limit, not the wallbox. The Sealion 7 accepts 11 kW AC, but only if your house supplies it (single-phase homes top out around 7 kW). The S07's AC limit is reported at about 7 kW, with another catalogue listing 6.6 kW, so ask the dealer for it in writing. Either way, a 22 kW wallbox is wasted money. Read our Thailand home charger guide for realistic installed costs of ฿35,000–65,000 if you pay yourself.
On the road, the Sealion Premium and Performance peak at 150 kW and the Ultimate at 230 kW. Changan claims the New S07 can go from 30% to 80% in 15 minutes, with a peak reported at 163 or 167 kW. These are manufacturer claims, and the Sealion Ultimate's own charging window is reported differently in different sources (10–80% in 24 minutes vs 30–80%). We could not verify real charging times under Thai heat for any of them.
Real-world efficiency: no fair winner yet
| Test | Result | Why it can't be compared |
|---|---|---|
| Sealion 7 AWD Performance (Clubza, Dec 2024) | 16.8 city / 20.9 highway / 18.8 combined kWh per 100 km | Dashboard readings, earlier model year |
| Original S07, 66.8 kWh NMC (Headlightmag, Mar 2024) | about 23.3 kWh per 100 km at 110 km/h, A/C on | Different battery generation; measured at the charger |
| New S07 LFP (Sanook, Jan 2026) | about 300 km driven hard, a suggested 400 km if restrained | Road-test observation, not a controlled full-depletion run |
Safety and features
| Sealion 7 | Deepal New S07 | |
|---|---|---|
| Euro NCAP | 5 stars (2025): adult 87%, child 93%, vulnerable road users 76%, safety assist 79% | 5 stars originally; reassessed in Dec 2025 after driver-monitoring changes |
| Display | 15.6-inch + 10.25-inch driver display + HUD | 15.6-inch swivelling screen, AR-HUD |
| Phone projection | Apple CarPlay and Android Auto | Wireless CarPlay; Android Auto not confirmed for Thailand |
| Audio | Dynaudio, 12 speakers | Sony, 14 speakers (reported) |
| ADAS | Adaptive cruise, AEB, lane assistance, blind-spot warning, cross-traffic alerts and surround cameras are listed for both | |
| Airbags | 8 or 9 (sources conflict) | 6 (reported) |
| Heat pump | Not confirmed for either Thai version | |
Euro NCAP tested European-specification cars. Whether Thai cars carry identical equipment is unverified. We found no ASEAN NCAP result for either model.
Ownership: service, resale and known issues
Service network. BYD's official locator shows 158 results, including North Star in Mahidol and Sansai (Chiang Mai) and outlets in Chiang Rai. Changan lists Sangchai and Charoen Auto in Chiang Mai, plus Chiang Rai and Lampang dealers, and its 2026 plan targets 100 locations across 60 provinces; whether that has been reached is unverified. Changan also announced a battery and e-drive service centre with CATL's service arm in July 2026. We found no parts-availability or repair-time data for either brand, so any claim that one is better supported is unverified.
Resale. We found a single 2025 Sealion 7 AWD Performance with 70–75,000 km asking ฿947,000 (One2car, Sept 2026) and a 2024 original S07 at ฿699,000. Those are asking prices for different cars, so they do not show a depreciation rate. Prices for both brands have moved sharply in Thailand, so treat any resale forecast with caution.
Reported problems. Individual owners have reported a steering pull on an early S07, a broken interior door handle and parts-cost dispute on a Sealion 7, and a Sealion battery fault after water exposure that was later approved under warranty. These are single reports, not proof of how common the faults are. The New S07's suspension was re-tuned for Thailand and one reviewer found the ride improved but the steering too light at speed. We found no model-specific official recall for either car, but that is not the same as confirmed clearance; ask the dealer to check your VIN.
Which one should you buy?
Deepal New S07
- Mostly city and regional driving, family of four or fewer
- You want the lowest price with a free home charger
- You are comfortable with a younger brand and a 5-year vehicle warranty
- Not for you if you need AWD or a very large battery
BYD Sealion 7 Premium
- You want the bigger battery and longer vehicle warranty
- You value a larger dealer network, including in the north
- You want 11 kW AC charging if your home supports it
- Costs about ฿100,900 more than the Deepal this month
Sealion 7 AWD Performance / Ultimate
- Hilly northern roads or frequent long trips
- You want AWD and strong performance
- Ultimate adds the largest battery and 230 kW DC charging
- Heavier cars: expect higher insurance and tyre costs
