We are WEY UAE, so we are naturally proud of our WEY 03. But we believe in honest comparisons. Let us look at both brands fairly.
Brand Background
WEY
WEY is positioned as a premium Chinese SUV brand. It was created with the specific intention of competing at the upper end of the market. WEY vehicles prioritize refined design, advanced hybrid systems, and connected technology. The WEY 03 is a compact plug-in hybrid SUV built for drivers who want premium quality with intelligent efficiency.
BYD
BYD is one of the world’s largest electric vehicle manufacturers. The company has developed its own battery technology and dual-mode hybrid systems. BYD has an extensive range globally, including both fully electric and plug-in hybrid models available in the UAE.
Battery Technology
WEY 03 Battery
The WEY 03 uses a 27.5 kWh battery in lithium iron phosphate and ternary lithium configurations. This is a substantial battery for a compact SUV. It provides up to 130 km of electric range under WLTC testing.

- Structural integration, the battery pack is built into the vehicle body, increasing rigidity
- Strong compressive resistance of up to 445 kN

- Total torque: 750 Nm
- Acceleration: 0-100 km/h in 6 seconds

- Front motor: 70 kW / Rear motor: 150 kW
BYD
BYD’s DM-i system targets fuel economy. Its fuel consumption in power-loss mode can go as low as 3.8 L per 100 km. The DM-p system targets performance, with 0-100 km/h times around 4.5 seconds in top variants.
In performance terms, the WEY 03 at 378 hp and 750 Nm sits firmly in the high-performance hybrid category. The BYD DM-p performance models are also strong, while DM-i variants prioritize economy over outright speed.
Electric Range
WEY 03
The WEY 03 delivers 130 km of electric range. For UAE daily driving, this covers virtually all regular commutes without touching the fuel tank.
BYD
BYD models vary significantly in range depending on model and specification. Some BYD PHEVs offer comparable or longer electric ranges in larger battery configurations.
The WEY 03’s 130 km WLTC figure is strong for UAE city driving. It comfortably covers most commuters’ daily needs.
Fuel Efficiency
WEY 03
- WLTC Combined Fuel Consumption: 0.99 L/100 km
- WLTC Minimum Charge State: 5.68 L/100 km
These are excellent figures. Less than 1 litre per 100 km with a charged battery is outstanding.
BYD
BYD’s DM-i system is specifically engineered for ultra-low fuel consumption. Figures as low as 3.8 L per 100 km in power-loss state are achievable in some models. For pure fuel economy, BYD DM-i is competitive.
