This complete engine assembly is a premium replacement option designed specifically for the BYD F3 and F3R models, featuring the renowned BYD473QB 1.5-liter inline-four powerplant. Engineered with advanced materials and cutting-edge technology, this long-block engine delivers reliable performance, improved fuel economy, and reduced emissions—ideal for drivers seeking durability and efficiency in urban and highway driving conditions.
Key Features:
- All-aluminum cylinder block for lightweight construction and enhanced thermal efficiency
- 16-valve DOHC configuration for optimized airflow and combustion
- Bosch-developed electronic fuel injection system for precise air-fuel mixture control
- Individual coil-on-plug ignition per cylinder for improved spark accuracy and reduced misfires
- Maintenance-free silent timing chain ensuring smooth operation without periodic adjustments
- Maximum output of 79kW at 5800 rpm and peak torque of 144 N·m available from 2800 rpm
The BYD473QB engine stands out due to its innovative engineering—featuring an all-aluminum alloy construction that reduces overall vehicle mass while improving handling dynamics and reducing wear on suspension components. Its compact design integrates seamlessly into existing chassis layouts, making it a practical choice for both OEM replacements and performance upgrades. The Bosch ECU-controlled fuel injection system ensures consistent power delivery across varying loads, enhancing drivability in city traffic or on open roads.
With a focus on longevity and low maintenance, this engine uses a silent timing chain instead of a traditional belt, eliminating the need for scheduled replacements and minimizing mechanical noise during operation. Each cylinder benefits from dedicated ignition coils, which improve combustion efficiency and reduce hydrocarbon emissions—an important factor for compliance with international environmental standards such as Euro 4/5.
Designed primarily for use in the BYD F3 and F3R models—including high-end variants like the Gold Diamond Edition—the BYD473QB long block offers a direct fitment solution for mechanics and DIY enthusiasts alike. Whether you're restoring a classic model or upgrading an older unit, this engine provides modern reliability and proven real-world performance.
Users frequently report smoother idling, quicker throttle response, and significantly better fuel economy compared to earlier versions of the F3’s original powertrains. Many owners note that after installing this engine, their vehicles feel more responsive in stop-and-go traffic, thanks to the early torque delivery at just 2800 RPM—a key advantage for city driving.
Common Questions:
Is this engine compatible with other BYD models? While engineered for the F3 and F3R, compatibility with similar platforms should be verified through professional assessment of mounting points and wiring harness integration.
Does it require special tools for installation? Standard automotive tools are sufficient; however, proper alignment of the timing chain and secure mounting of sensors are recommended for optimal results.
Can I expect improved fuel consumption? Yes—due to the combination of aluminum construction, efficient combustion chamber design, and Bosch EFI calibration, many users report up to 10–15% improvement in average miles per gallon when replacing older engines.
What makes this engine different from generic replacements? Unlike off-brand or reconditioned units, the BYD473QB assembly uses factory-grade components, including precision-machined internals, genuine timing components, and certified electronic modules—ensuring consistent performance over time.
For global consumers aged 18 and above who prioritize performance, dependability, and cost-effective ownership, this engine assembly represents a smart investment in vehicle longevity and driving satisfaction.
