Powertrain & Engine Architecture
The Kaiyi Shiyue 28.08 kWh Electric utilizes a front-wheel-drive configuration powered by a single synchronous electric motor. This motor produces 54 horsepower and 110 Nm (81.13 lb.-ft.) of torque. The energy is supplied by a 28.08 kWh lithium iron phosphate (LiFePO4) battery pack, positioned under the vehicle floor to optimize weight distribution and passenger space. LiFePO4 chemistry is favored for its improved thermal stability and longer cycle life compared to other lithium-ion battery types, though it generally offers a slightly lower energy density. The vehicle employs a single-speed automatic transmission, typical for electric vehicles, providing seamless acceleration. The motor controller manages power delivery and regenerative braking, capturing energy during deceleration to extend the vehicle’s range.
Driving Characteristics
The Shiyue 28.08 kWh Electric prioritizes efficiency and ease of use over outright performance. With 54 hp, acceleration is modest, geared towards smooth urban driving rather than rapid overtaking. The single-speed transmission provides linear power delivery, and the electric motor offers instant torque, making it responsive in city traffic. The vehicle’s relatively light weight (1040 kg / 2292.81 lbs.) helps to mitigate the limited power output. While not comparable to higher-powered electric vehicles or even gasoline-powered cars, the Shiyue offers adequate performance for its intended purpose. The regenerative braking system contributes to a more intuitive driving experience, allowing for one-pedal driving in certain conditions.
Equipment & Trim Levels
As an entry-level model, the Kaiyi Shiyue 28.08 kWh Electric is equipped with essential features. Standard equipment typically includes air conditioning, power windows, a basic infotainment system with Bluetooth connectivity, and ABS (Anti-lock Braking System). Interior upholstery is likely to be cloth, and the dashboard design is functional and straightforward. Optional extras may include a rearview camera, upgraded infotainment with a larger touchscreen, and alloy wheels. The focus is on providing a practical and affordable transportation solution, so luxury features are limited.
Chassis & Braking
The Shiyue utilizes a McPherson strut independent suspension system at the front, providing a comfortable ride and responsive handling. The rear suspension employs a torsion beam setup, which is a cost-effective solution for compact vehicles. The braking system features ventilated discs at the front and drum brakes at the rear. While the front discs offer better stopping power, the rear drums represent a cost-saving measure. Electric power steering provides light and easy steering feel, making it maneuverable in urban environments. The vehicle rides on 15-inch wheels with 165/65 R15 tires.
Market Reception & Comparison
The Kaiyi Shiyue 28.08 kWh Electric is positioned to compete with other affordable electric hatchbacks in the Chinese market. Critics have generally praised its affordability and practicality, but have noted its limited range and modest performance. Compared to other trims within the Shiyue lineup (if available), this variant offers the lowest price point but also the shortest range and slowest acceleration. Its fuel economy, measured in kilowatt-hours per 100 kilometers, is competitive with other EVs in its class. Reliability data is still emerging, but the use of LiFePO4 battery technology suggests good long-term durability.
Legacy
The Kaiyi Shiyue 28.08 kWh Electric represents a significant step for Kaiyi in the electric vehicle market. While it may not be a groundbreaking vehicle in terms of technology or performance, it provides an accessible entry point for consumers looking to transition to electric mobility. The long-term reliability of the powertrain remains to be seen, but the LiFePO4 battery pack is expected to offer a long service life. In the used car market, this variant is likely to appeal to budget-conscious buyers seeking a practical and efficient city car. Its success will depend on Kaiyi’s ability to establish a strong reputation for quality and reliability in the competitive EV landscape.
