BYD Dolphin Specifications: The Complete Verified Spec Sheet
Share
The BYD Dolphin comes in two variants. The Standard Range has a 70 kW motor, a 135 Ah LFP Blade battery, and a 150 km/h top speed. The Extended Range has a 150 kW motor, a 150 Ah battery, and 160 km/h. Both measure 4,290 mm long with a 2,700 mm wheelbase. Every figure on this page is verified against the BYD Dolphin owner's manual, making it a spec sheet you can trust.
Why This Spec Sheet Is Different
Specification pages online often mix markets, model years, and guesswork. This one takes a different approach: every number below comes from the BYD Dolphin owner's manual, the document BYD itself provides with the car.
Where a commonly quoted figure is not in the manual, such as battery kilowatt-hours, it is flagged clearly so you know its source. The result is the specification sheet as BYD documents it, section by section.
Powertrain
| Measurement | Standard Range | Extended Range |
|---|---|---|
| Motor model | TZ180XSF | TZ200XSQ |
| Motor type | Permanent magnet synchronous | |
| Peak power | 70 kW | 150 kW |
| Peak torque | 180 Nm | 310 Nm |
| Rated power | 35 kW | 65 kW |
| Drive type | 2WD (front) | |
The peak figures are what you feel when accelerating, and the gap between variants is significant: the Extended Range more than doubles the Standard's power, transforming the car's character.
Performance and Economy
| Measurement | Standard Range | Extended Range |
|---|---|---|
| Top speed | 150 km/h | 160 km/h |
| Consumption (NEDC) | 12.6 kWh/100 km | 14.2 kWh/100 km |
| Max gradeability | 30 percent | |
The NEDC consumption figures are the manual's official baseline. Real-world use varies with conditions, but they show the Standard Range as the marginally more efficient car.
Battery
| Measurement | Standard Range | Extended Range |
|---|---|---|
| Type | Lithium iron phosphate (LFP Blade) | |
| Rated capacity | 135 Ah | 150 Ah |
| Usable energy (market) | About 44.9 kWh | About 60.5 kWh |
The manual quotes capacity in amp-hours, while the familiar kilowatt-hour figures come from market specifications. Because it is LFP, the battery is designed to be charged to 100 percent, and our Blade battery guide for the Dolphin explains the chemistry and the right charging habits in detail.
Dimensions
| Measurement | Figure |
|---|---|
| Length | 4,290 mm |
| Width (excluding mirrors) | 1,770 mm |
| Height | 1,570 mm |
| Wheelbase | 2,700 mm |
| Front / rear track | 1,530 mm / 1,530 mm |
| Front / rear overhang | 830 mm / 760 mm |
| Approach / departure angle | 16 degrees / 23 degrees |
Weights
| Measurement | Standard Range | Extended Range |
|---|---|---|
| Curb weight | 1,506 kg | 1,658 kg |
| Max total mass (GVM) | 1,916 kg | 2,068 kg |
| Payload (calculated) | 410 kg | 410 kg |
| Occupants | 5 | |
Wheels and Tyres
| Measurement | Standard Range | Extended Range |
|---|---|---|
| Tyre size | 195/60R16 | 205/50R17 |
| Recommended pressure | 250 kPa (36 psi) | |
| Wheel balance requirement | 10 g or less | |
Brakes and Chassis
| Measurement | Specification |
|---|---|
| Front friction plate thickness | 2.5 to 8 mm |
| Rear friction plate thickness | 2 to 6.5 mm |
| Front camber (at curb weight) | -0.82 degrees, plus or minus 0.75 |
The friction plate ranges are the manual's service limits, useful when a workshop assesses brake wear. Remember that regenerative braking does much of the everyday slowing on an EV, so the physical brakes typically wear more slowly than on a petrol car.
Fluids and Consumables
| Measurement | Specification |
|---|---|
| Transmission oil | Castrol BOT384, 450 ml (Standard) / 600 ml (Extended) |
| Brake fluid | HZY6, 1,100 ml |
| Motor coolant | Glycol organic acid, -40 C freezing point, 3.1 L / 3.3 L |
| A/C refrigerant | R1234yf, 1,000 g |
These fluid specifications are gold for servicing, and few spec pages publish them. They are exactly what a workshop needs to service the car to BYD's standard.
What the Two Spec Columns Really Mean
A useful insight for buyers: the manual's two specification columns correspond to the two variants sold in markets like Australia. The Standard Range pairs the smaller battery with the 70 kW motor and 16-inch wheels, while the Extended Range pairs the larger battery with the 150 kW motor and 17-inch wheels.
So when you compare trims at a dealership, you are effectively choosing between these two manual columns. The differences run through power, battery, wheels, weight, and even coolant volume.
