The Hongqi H5 I (facelift, introduced in 2020) 1.8T Mild Hybrid Automatic represents a significant step in the revitalization of the Hongqi brand, a historically important Chinese automaker. Produced from 2020 to 2022, this variant occupied a key position in the H5 lineup, offering a balance of performance, fuel efficiency, and modern technology. The H5 itself is a mid-size sedan designed to compete within the burgeoning Chinese domestic market, aiming to provide a domestically-produced alternative to established international brands. This facelifted version, designated the “I” variant, brought updated styling and powertrain refinements, including the introduction of mild hybrid technology to enhance fuel economy and reduce emissions. It’s built on the Hongqi H5 platform, a front-engine, front-wheel-drive architecture.

Powertrain & Engine Architecture
At the heart of the H5 I 1.8T Mild Hybrid is the CA4GB18TD-30 engine, a 1.8-liter turbocharged inline-four cylinder gasoline engine. This engine utilizes direct fuel injection, a technology that improves fuel efficiency and power output by injecting fuel directly into the combustion chamber. The engine also features a double overhead camshaft (DOHC) valvetrain, optimizing airflow for enhanced performance. The turbocharger, coupled with an intercooler, forces more air into the engine, boosting horsepower and torque. The mild hybrid system incorporates a 48-volt electrical system and a small electric motor that assists the engine during acceleration and allows for regenerative braking, capturing energy normally lost during deceleration to recharge the battery. This system doesn’t allow for fully electric driving, but it significantly improves fuel economy and reduces emissions. The engine is paired with a 6-speed automatic transmission, chosen for its smooth operation and ease of use, catering to the preferences of the target market.
Driving Characteristics
The 197 horsepower and 236 lb-ft of torque delivered by the 1.8T engine provide adequate performance for everyday driving. Acceleration from 0-60 mph in approximately 7.6 seconds is respectable for a mid-size sedan. Compared to lower-powered versions of the H5, the 1.8T offers a noticeably more responsive driving experience. However, it doesn’t match the outright performance of higher-spec models. The automatic transmission is tuned for comfort and efficiency, with gear changes generally smooth and unobtrusive. The mild hybrid system provides a subtle boost during acceleration, enhancing responsiveness without being overly intrusive. The front-wheel-drive configuration provides predictable handling, although it may not offer the same level of dynamic engagement as rear-wheel-drive alternatives.
Equipment & Trim Levels
The H5 I 1.8T Mild Hybrid Automatic typically came well-equipped, reflecting Hongqi’s ambition to offer a premium experience. Standard features generally included leather upholstery, automatic climate control, a touchscreen infotainment system with navigation, and a suite of safety features such as ABS, electronic stability control, and multiple airbags. Higher trim levels offered additional features like a panoramic sunroof, premium audio system, and advanced driver-assistance systems (ADAS) such as adaptive cruise control and lane departure warning. Interior design emphasized a modern and luxurious aesthetic, with high-quality materials and attention to detail.
Chassis & Braking
The H5 I utilizes an independent McPherson strut suspension at the front and an independent multi-link suspension at the rear, providing a comfortable ride and good handling characteristics. Stabilizer bars are fitted to both axles to reduce body roll during cornering. The braking system consists of ventilated discs at the front and solid discs at the rear, providing adequate stopping power. Electric power steering offers light and precise steering feel. The tires are typically sized 225/45 R19, providing a good balance of grip and ride comfort.
Market Reception & Comparison
The Hongqi H5 I 1.8T Mild Hybrid Automatic was generally well-received in the Chinese market. Critics praised its stylish design, comfortable interior, and improved fuel efficiency thanks to the mild hybrid system. Compared to other 1.8-liter turbocharged sedans in its class, the H5 offered a competitive level of performance and features. However, some reviewers noted that the driving experience wasn’t as engaging as some European or Japanese competitors. The mild hybrid system offered a noticeable improvement in fuel economy compared to the non-hybrid versions of the H5, making it an attractive option for environmentally conscious buyers.
Legacy
The Hongqi H5 I 1.8T Mild Hybrid Automatic played a crucial role in establishing Hongqi as a credible competitor in the Chinese automotive market. The powertrain, while not groundbreaking, proved to be reliable and efficient. On the used car market, these models are generally sought after for their combination of comfort, features, and fuel economy. The introduction of mild hybrid technology demonstrated Hongqi’s commitment to innovation and sustainability, paving the way for future electrified models. While long-term reliability data is still emerging, early indications suggest that the CA4GB18TD-30 engine is a durable and dependable unit, provided it receives regular maintenance.
