The Soueast S09 2.0 TGDI, launched in September 2024, represents a significant offering in the mid-size SUV segment. This variant, equipped with a 2.0-liter turbocharged gasoline direct injection (TGDI) engine producing 197 horsepower and a 7-speed dual-clutch transmission (DCT), positions itself as a performance-oriented option within the S09 lineup. The S09 itself is a seven-seat SUV, built on a dedicated platform, aiming to provide a blend of space, comfort, and modern technology. This particular trim level targets buyers seeking a more engaging driving experience compared to potentially lower-powered engine options that may have been offered.
Soueast S09 2.0 TGDI: Powertrain & Engine Architecture
At the heart of the S09 2.0 TGDI lies the SQRF4J20 engine, a 1998cc (121.93 cu. in.) inline-four cylinder powerplant. 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 turbocharger with an intercooler, which forces more air into the cylinders, further boosting performance. The valvetrain employs a Double Overhead Camshaft (DOHC) configuration, optimizing valve timing for improved engine breathing. Compression ratio is set at 10.2:1. The engine is equipped with a Start & Stop System, contributing to reduced fuel consumption in urban driving conditions.
The 7-speed dual-clutch transmission (DCT) is a key component of this variant. DCTs offer faster and smoother gear changes compared to traditional automatic transmissions, enhancing both acceleration and driving enjoyment. The DCT’s programming is tuned to provide responsive shifts and efficient power delivery. While specific gear ratios haven’t been widely published, the DCT is designed to keep the engine within its optimal power band during acceleration and cruising.
Engine Specifications
The SQRF4J20 engine delivers a maximum power output of 197 hp (horsepower) at 5500 rpm and a peak torque of 375 Nm (276.59 lb.-ft.) between 1750 and 4000 rpm. This broad torque curve suggests good responsiveness across a wide range of engine speeds. The engine’s power-to-liter ratio is 98.6 hp/l, indicating a relatively high output for its displacement.
Driving Characteristics
The Soueast S09 2.0 TGDI offers a noticeably more spirited driving experience than lower-powered versions of the S09. The combination of the turbocharged engine and the DCT results in brisk acceleration. Independent testing indicates a 0-100 km/h (0-62 mph) time of 8.5 seconds, and a 0-60 mph time of approximately 8.1 seconds. The DCT provides quick and seamless gear changes, minimizing power interruption during acceleration. The engine’s torque output allows for confident overtaking maneuvers. While the S09 is primarily a front-wheel-drive vehicle, the DCT and engine characteristics contribute to reduced torque steer compared to some other turbocharged front-wheel-drive vehicles.
The driving experience is further enhanced by the S09’s suspension tuning, which aims to balance comfort and handling. The McPherson strut front suspension and multi-link rear suspension contribute to a stable and controlled ride. The electric power steering provides a responsive and precise feel.
Equipment & Trim Levels
The 2.0 TGDI trim of the Soueast S09 is positioned as a mid-to-upper level offering. Standard equipment typically includes features such as alloy wheels (likely 20-inch, given the tire size), a modern infotainment system with touchscreen display, automatic climate control, power-adjustable seats, and a comprehensive suite of safety features including ABS (Anti-lock Braking System). The interior is likely to feature a combination of fabric and leather upholstery, with higher-grade materials used on the dashboard and door panels. Optional extras may include a panoramic sunroof, premium audio system, advanced driver-assistance systems (ADAS) such as adaptive cruise control and lane departure warning, and upgraded interior trim options.
Chassis & Braking
The S09 2.0 TGDI utilizes an independent suspension system at both the front and rear. 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 braking system consists of ventilated discs at the front and solid discs at the rear, providing adequate stopping power for the vehicle’s weight and performance. The ABS system enhances braking safety by preventing wheel lockup during emergency stops.
The S09 2.0 TGDI rides on 255/45 R20 tires mounted on 8.5J x 20 inch wheel rims. This tire size provides a good balance of grip and ride comfort.
Market Reception & Comparison
As a relatively new model, comprehensive long-term market reception data for the Soueast S09 2.0 TGDI is still developing. However, initial reviews suggest that the 2.0 TGDI variant is well-received for its performance and driving dynamics. Compared to potential lower-powered engine options within the S09 lineup, the 2.0 TGDI offers a more engaging and responsive driving experience. Fuel economy is rated at 8 l/100 km (29.4 US mpg, 35.3 UK mpg, 12.5 km/l) combined, which is typical for a turbocharged 2.0-liter SUV. CO2 emissions are rated at 187 g/km, meeting Euro 6 emission standards.
Reliability data is currently limited, but Soueast has been working to improve the quality and reliability of its vehicles. The use of a DCT transmission, while offering performance benefits, may require more frequent maintenance compared to a traditional automatic transmission.
