The 2025 BYD Atto 2 DM-i is a new plug-in hybrid (PHEV) SUV positioned as the smallest offering in BYD’s growing UK lineup. Measuring 4.3 meters in length, it’s a direct competitor to popular models like the MG ZS, Renault Captur, and Toyota C-HR. This vehicle builds on the already-released electric Atto 2, adding a gasoline engine for extended range and flexibility.
How BYD’s DM-i System Works
BYD’s DM-i (Dual-Mode – Intelligent) powertrain is a unique hybrid approach. It combines elements of Toyota’s self-charging hybrids and Nissan’s range-extender systems. The gasoline engine primarily generates electricity to recharge the battery, which then powers the electric motor driving the wheels. Under high loads or at highway speeds, the engine can directly connect to the drivetrain for maximum power.
The Atto 2 DM-i uses a 1.5-liter four-cylinder engine running on the efficient Atkinson cycle, paired with a 194-horsepower electric motor. The top-spec “Boost” model boasts an 18.3 kWh battery, providing up to 56 miles of electric-only range. A cheaper “Active” trim uses a smaller 7.8 kWh battery for 25 miles of electric driving but suffers from slower charging speeds.
Interior and Tech: Familiar Yet Refined
The interior of the Atto 2 DM-i is nearly identical to its electric counterpart. It features a 12.8-inch central touchscreen (no longer rotating, following customer feedback), an 8.8-inch digital instrument display, and essential physical controls. While the interface is functional, some menu structures are illogical and can feel overwhelming.
Despite the smaller battery in the PHEV version, interior space remains competitive. Rear seats are spacious, and the 425-liter boot matches most rivals in its class.
Driving Experience: Seamless and Efficient
The DM-i system operates smoothly, often feeling like a pure electric vehicle. Acceleration is brisk, with a responsive torque curve. The engine engages only when needed, and even then, it does so almost imperceptibly. A “hold” mode allows the engine to run continuously, but the system is most efficient in hybrid mode.
In real-world testing, the Atto 2 DM-i achieved impressive fuel economy: 157 mpg combined with a 9.12 mpkWh electricity consumption rate. However, these figures depend on starting with a fully charged battery.
Ride and Handling: Comfortable and Competent
The Atto 2 DM-i delivers a comfortable ride, absorbing speed bumps and potholes effectively. Steering is weighted appropriately, providing good maneuverability. The car remains stable at highway speeds, with ample power for overtaking. Some wind noise is present, but no more than typical for this class.
Charging and Value: Key Considerations
To maximize efficiency, the Atto 2 DM-i requires regular charging. Without it, fuel economy will be similar to traditional hybrids like the Toyota Yaris Cross or Renault Captur. The 6.6 kW maximum charging speed is relatively slow, meaning public chargers may take hours to provide a significant charge.
The cheaper “Active” trim is not recommended due to its limited electric range (25 miles) and painfully slow 3.3 kW charging speed. The benefits of the PHEV system are less pronounced in this configuration.
Conclusion: The BYD Atto 2 DM-i is a well-executed PHEV that offers a compelling blend of electric efficiency and gasoline-powered range. Its seamless hybrid operation, comfortable ride, and competitive pricing make it a strong contender in the compact SUV segment, but consistent charging is essential to unlock its full potential.
