The Soueast S09 2.0 TGDI (254 Hp) DCT is a five to seven-seat sport utility vehicle (SUV) introduced by the Chinese manufacturer Soueast Motor in September 2024. Representing a significant step up in the Soueast lineup, the S09 is positioned as a premium offering, targeting consumers seeking a blend of performance, technology, and spaciousness. It is built on a dedicated SUV platform and represents Soueast’s ambition to compete in the increasingly competitive mid-size SUV segment. The 2.0 TGDI DCT variant is the top-tier trim level, distinguished by its powerful turbocharged engine and dual-clutch transmission.
Soueast S09 2.0 TGDI: Powertrain & Engine Architecture
At the heart of the S09 2.0 TGDI is the SQRF4J20, a 2.0-liter inline-four cylinder gasoline engine. This engine utilizes direct fuel injection and is coupled with a single turbocharger and intercooler to achieve a power output of 254 horsepower at 5500 rpm and 390 Nm (287.65 lb-ft) of torque available from 1750 to 4000 rpm. This configuration results in a specific power output of 127.1 hp per liter. The engine features a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, optimizing airflow for enhanced performance. A Start & Stop system is included as standard, contributing to improved fuel efficiency in urban driving conditions.
The engine is paired with a 7-speed dual-clutch transmission (DCT). DCTs are known for their rapid and smooth gear changes, offering a more engaging driving experience compared to traditional automatic transmissions. The DCT in the S09 is tuned for both performance and efficiency, providing quick acceleration while maintaining reasonable fuel economy. The powertrain is front-wheel drive, a common configuration for vehicles in this class.
Engine Specifications
The SQRF4J20 engine boasts a bore of 80.5 mm (3.17 in) and a stroke of 98.12 mm (3.86 in), resulting in a displacement of 1998 cm³ (121.93 cu. in). The compression ratio is set at 10.2:1, a balance between efficiency and performance. The engine’s design incorporates modern materials and manufacturing techniques to ensure durability and reliability.
Driving Characteristics
The Soueast S09 2.0 TGDI delivers brisk acceleration, achieving 0-100 km/h (0-62 mph) in approximately 8 seconds, and 0-60 mph in 7.6 seconds. The turbocharger provides a noticeable boost in power, particularly in the mid-range, making overtaking maneuvers effortless. The DCT contributes to a responsive driving experience, with minimal torque interruption during gear changes. While not a dedicated sports SUV, the S09 offers a level of performance that is competitive within its segment. The front-wheel-drive configuration provides adequate traction in most conditions, although it may exhibit some torque steer under hard acceleration.
The gear ratios of the 7-speed DCT are optimized for both acceleration and fuel efficiency. Lower gears provide quick off-the-line acceleration, while higher gears allow for relaxed cruising at highway speeds. The transmission’s shift logic is designed to adapt to driving conditions and driver input, providing a seamless and intuitive driving experience.
Equipment & Trim Levels
The 2.0 TGDI variant of the Soueast S09 is the highest trim level and comes standard with a comprehensive suite of features. Interior appointments include premium upholstery, likely leather or a high-quality synthetic material, and a modern dashboard design. Standard equipment typically includes a large touchscreen infotainment system with navigation, smartphone integration (Apple CarPlay and Android Auto), a panoramic sunroof, automatic climate control, and a suite of advanced driver-assistance systems (ADAS). These ADAS features may include adaptive cruise control, lane departure warning, automatic emergency braking, and blind-spot monitoring. Optional extras may include upgraded sound systems, premium interior trim packages, and additional safety features.
Chassis & Braking
The Soueast S09 utilizes an independent suspension system on both the front and rear axles. The front suspension employs a McPherson strut design with coil springs and an anti-roll bar, while the rear suspension features a multi-link setup with a stabilizer bar. This configuration is designed to provide a comfortable ride while maintaining good handling characteristics. The vehicle is equipped with ventilated disc brakes on the front wheels and solid disc brakes on the rear wheels. The braking system is assisted by ABS (Anti-lock Braking System) to enhance safety and control during emergency braking situations. The S09 rides on 255/45 R20 tires mounted on 8.5J x 20 inch alloy wheels.
Market Reception & Comparison
As a relatively new entrant to the market, the Soueast S09 2.0 TGDI has received mixed reviews. Critics have praised its spacious interior, comfortable ride, and powerful engine. However, some have noted that the interior materials, while improved, may not be on par with established competitors. Fuel economy is rated at 8.1 l/100 km (29 US mpg, 34.9 UK mpg, 12.3 km/l), which is competitive for a vehicle of this size and performance. Compared to other trims in the S09 lineup, the 2.0 TGDI offers significantly more power and a more engaging driving experience, but at a higher price point. Reliability data is still emerging, but Soueast has been working to improve the overall quality and durability of its vehicles.

However, Soueast has been investing in quality control and engineering improvements in recent years. The DCT, while offering performance benefits, can be more complex and potentially more expensive to maintain than traditional automatic transmissions. In the used car market, the S09 2.0 TGDI is expected to hold its value reasonably well, particularly if it proves to be a reliable and well-maintained vehicle. Its combination of performance, features, and spaciousness should appeal to a wide range of buyers.
