This page lists 3 cars: the BYD Dolphin, the BYD Atto 3 and the BYD Seal. All are electric, automatic and have 5 seats. Body types here are crossover, hatchback and sedan.
Daily prices on this page run from ฿850 to ฿1400. The BYD Dolphin is ฿850 per day, the BYD Atto 3 is ฿1200 per day and the BYD Seal is ฿1400 per day.
Thailand's Ministry of Transport says a foreigner drives on a valid Thai licence, a valid international driving permit or an ASEAN licence. The document does not state any stay limits. Some Koh Samui rental shops ask for licences with Latin-script details.
Compulsory insurance is included in every BYD car rental in Koh Samui from Rent-Trip. Three electric cars are on this page — the BYD Dolphin from ฿850 a day, the BYD Atto 3 at ฿1,200 and the BYD Seal at ฿1,400 — each with five seats and an automatic transmission.
The table below sets out what separates them.
| Model | Body | Battery | Power | Drive | Seats | Transmission | Price per day |
|---|---|---|---|---|---|---|---|
| BYD Dolphin | Hatchback | 44.9 kWh | 95 hp | Front-wheel | 5 | Automatic | ฿850 |
| BYD Atto 3 | Crossover | 60.5 kWh | 204 hp | Front-wheel | 5 | Automatic | ฿1,200 |
| BYD Seal | Sedan | 82.5 kWh | 313 hp | Rear-wheel | 5 | Automatic | ฿1,400 |
The sedan carries the largest pack at 82.5 kWh and puts its power through the rear wheels.
The longer you book, the lower the per-day figure — worth checking before you split a stay into separate short bookings. In October and November, when rainfall peaks at 294.9 mm and 444.6 mm, a monthly booking also spares you re-booking every few days between showers.
Battery size, power output and drive layout decide how each of the three cars behaves on the 51 km ring road that links Nathon, Lipa Noi, Lamai, Chaweng, Bophut and Maenam. Here is what the numbers look like in practice.
The Dolphin carries a 44.9 kWh pack and sends 95 hp through the front axle, the Atto 3 pairs 60.5 kWh with 204 hp, likewise front-driven, and the Seal tops the trio with 82.5 kWh and 313 hp routed to the rear. Check the charge level against your planned distance before you set off rather than trusting a percentage on the dash.
The one habit worth breaking early is reaching for the gear selector with your right hand — it sits on your left here, so the first few kilometres through Chaweng or Lamai are the ones to take slowly. Set your mirrors and seat before you leave the delivery point, not in traffic.
If you are unsure which body suits your route, tell us what your days look like and we will match the car to the trip rather than the other way round.
Longer bookings on this page follow a fixed rule, not a negotiation: weekly is the daily rate times six, monthly is the daily rate times twenty-one. That makes the arithmetic simple enough to do before you message us.
| Model | Per day | Per week | Per month |
|---|---|---|---|
| BYD Dolphin | ฿850 | ฿5,100 | ฿17,850 |
| BYD Atto 3 | ฿1,200 | ฿7,200 | ฿25,200 |
| BYD Seal | ฿1,400 | ฿8,400 | ฿29,400 |
The multiplier is fixed across the fleet, so you can work out any model's longer rate yourself before you ask. Bookings start from one day, so nothing stops you combining a short hire at the beginning of a trip with a longer one later.
Nothing above is a figure we can quote from memory — where a number is not printed here, it belongs to the agreement you sign, not to this page.
If your stay on Koh Samui runs past a week, it is worth checking the monthly figure before you split the trip into separate short bookings — the second one usually starts the count again at the daily rate.
We deliver the car to any address on Koh Samui and to Samui International Airport (USM). The delivery address, the date and the time are agreed with a manager before the booking is fixed, and a delivery fee, if any, is agreed when booking. Nothing about the hand-over is left to guesswork: you tell us where you are staying, we confirm what works.
Documents are passport, home driving licence, International Driving Permit unless you hold an ASEAN licence, and a bank card in the main driver's name. Minimum driver age is 21; conditions for drivers under 25 are set out in the rental agreement. The card is used for the security hold, and the amount is set out in the agreement. Since 30 December 2025 a car rental agreement is a contract controlled by the OCPB: it is written in Thai, and all fees and penalties are disclosed in it. Traffic-camera fines are issued to the car owner and re-invoiced to the renter.
Day trips we have pages for include the round-the-island loop, Na Muang waterfall, Secret Buddha Garden, the Lamai viewpoint and Ang Thong Marine Park.
Thai traffic keeps to the left, which is why every car in our BYD fleet is right-hand drive — the same as every registered vehicle on the island. Before you take the wheel, two documents matter more than anything else in the agreement.
Every registered car carries compulsory motor insurance (Por Ror Bor), which covers injury to third parties. First-class (Class 1) insurance covers damage to the car itself; its terms and the excess sit in the rental agreement, as do the security hold taken on the bank card and the minimum driver age of 21. Conditions for drivers under 25 and for premium classes sit in the same agreement. VAT 7% is already included in the prices shown.
The ring road is 51 km and connects the lowland with the coast; Nathon, Lipa Noi, Lamai, Chaweng, Bophut and Maenam all sit on it.
Most operators here do not allow their cars to leave the island: a breakdown or a crash on the mainland gets expensive. Raja Ferry Port runs Don Sak to Lipa Noi in about 1 h 30 min, hourly from 05:00 to 19:00, 15 sailings, with extra departures when the queue builds. The provincial tariff is ฿200 per passenger and ฿640 for a four-wheeled car, and electric and hybrid vehicles go in a separate category in the booking form. Once on the mainland, Khanom is 26.5 km from the Don Sak pier, Surat Thani 66.1 km, Krabi 208.9 km.
October to December is the wet stretch: 294.9 mm in October, 444.6 mm in November, 263.1 mm in December, against 64.3 mm in February. The other local habit is parking — the kerb painted red-and-white or yellow-and-white is a no-stopping zone, and the penalty for it is set out in the rental agreement.
