The engine model of the Jianghuai S4 is hfc4gb2.4e, which functions to provide the necessary power for the vehicle's movement. The Jianghuai S4 is equipped with a 1.5T inline 4-cylinder turbocharged engine, with a maximum horsepower of 150PS, a maximum power of 110kW, and a maximum torque of 210Nm, paired with a 6-speed automatic manual transmission. The front suspension of the Jianghuai S4 is a MacPherson independent suspension, and the rear suspension is a torsion beam non-independent suspension. Its body dimensions are: 4410mm in length, 1800mm in width, and 1660mm in height, with a wheelbase of 2620mm, a fuel tank capacity of 50L, and a body weight of 1365kg.

I've driven the JAC Refine S4, which is typically equipped with the HFC4GB2.4D engine, a 1.5-liter turbocharged gasoline engine delivering around 150 horsepower and substantial torque. Paired with either a manual or CVT transmission, it runs smoothly. This engine is quite common, developed in-house by JAC, and features direct injection technology to enhance fuel efficiency. Every time I accelerate on the highway, the power delivery feels smooth, with an average fuel consumption of 8-9 liters per 100 kilometers—decent for city driving. The design has some noise issues, but maintenance is straightforward; just change the oil every 5,000 kilometers to keep it in good condition. When purchasing, check the nameplate to confirm the model, as there might be minor variants across different batches—getting the wrong model could affect warranty coverage. Overall, it offers good value for money, suitable for daily commutes or family trips, and is easy to drive without feeling exhausting.

As a JAC S4 owner, my car is equipped with the HFC4GB2.4D engine, a 1.5T displacement model. It provides sufficient power for daily commuting and handles city traffic effortlessly. The engine nameplate is clearly visible on the hood, and mechanics always praise its reliability and low failure rate during maintenance. Fuel consumption is moderate, with one tank lasting about 650km on long trips, though cold starts are slightly slower in winter. When paired with the transmission, it delivers smooth driving with minimal jerkiness. Regular carbon deposit checks are recommended to maintain performance. The engine's overall design emphasizes practicality and outstanding cost-performance ratio. Compared to domestic cars in the same price range, it's slightly noisier but more durable - easily lasting five years with affordable spare parts.

The HFC4GB2.4D is the main engine of the JAC Refine S4, a 1.5T turbocharged unit with approximately 150 horsepower. During my research, I found it belongs to JAC's HFC series, widely used in multiple models, with technology derived from independent development and compliant with China VI emission standards. It delivers linear power output with quick response at low RPMs, making it suitable for urban roads. Daily driving shows good fuel consumption control, but noise becomes noticeable under high load. Compared to older models, it features upgraded fuel systems, compact structure, and easy maintenance. Regular maintenance is recommended to extend lifespan and maintain efficient operation.
