The Soueast S07 1.5T (156 Hp) DCT is a compact SUV produced by the Chinese manufacturer Soueast Motor since September 2024. Representing a significant step forward for the brand, the S07 aims to compete in the increasingly popular SUV segment with a focus on modern styling, technology, and a turbocharged powertrain. This particular variant, equipped with the 1.5-liter turbocharged engine and a dual-clutch transmission (DCT), occupies a mid-range position within the S07 lineup, offering a balance between performance, fuel efficiency, and affordability. It is built on a dedicated SUV platform and is designed to accommodate five to seven passengers, depending on the configuration.
Soueast S07 1.5T: Powertrain & Engine Architecture
At the heart of the S07 1.5T lies the SQRE4T15C engine, a 1.5-liter inline-four cylinder gasoline engine. This engine utilizes a turbocharger and intercooler to boost power output to 156 horsepower at 5500 rpm and 230 Nm (169.64 lb-ft) of torque between 1750 and 4000 rpm. The engine features multi-port fuel injection and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The compression ratio is set at 9.5:1. The engine’s bore and stroke are 77mm and 80.5mm respectively, resulting in a displacement of 1498 cm³ (91.41 cu. in.).
The engine is paired with a 6-speed dual-clutch transmission (DCT). DCTs offer faster and smoother gear changes compared to traditional automatic transmissions, contributing to improved acceleration and fuel efficiency. The DCT in the S07 is designed for front-wheel drive applications, and its gear ratios are tuned to provide a balance between responsive acceleration and comfortable cruising. The specific gear ratios haven’t been publicly released by Soueast, but are likely optimized for the engine’s torque curve.
Engine Code & Specifics
The SQRE4T15C engine code designates a specific iteration of Soueast’s 1.5-liter turbocharged engine. While detailed internal differences between engine code variants are not widely publicized, it’s understood that this version is optimized for the S07’s weight and intended driving characteristics. The engine meets Euro 6 B emission standards, indicating a commitment to reducing harmful emissions.
Driving Characteristics
The Soueast S07 1.5T delivers a respectable driving experience for its class. Acceleration from 0 to 100 km/h (0-62 mph) takes approximately 13 seconds, while 0-60 mph is achieved in around 12.4 seconds. The maximum speed is electronically limited to 180 km/h (111.85 mph). The turbocharger provides a noticeable boost in power during acceleration, making overtaking maneuvers relatively easy. The DCT contributes to smooth and quick gear changes, enhancing the overall driving experience. However, compared to more powerful engine options (if available in other S07 trims), the 1.5T variant offers a more moderate level of performance, prioritizing fuel efficiency and everyday usability.
The front-wheel-drive configuration provides adequate traction in most driving conditions. The suspension setup, consisting of an independent McPherson strut front suspension and an independent multi-link rear suspension, aims to provide a comfortable ride while maintaining reasonable handling characteristics. The steering is electrically assisted, offering light and precise control.
Equipment & Trim Levels
The S07 1.5T typically comes standard with a range of features designed to appeal to modern SUV buyers. These include air conditioning, power windows and locks, a touchscreen infotainment system, and basic safety features such as ABS (Anti-lock Braking System). The interior upholstery is generally cloth, although higher trim levels may offer leather options. The dashboard layout is modern and functional, with a focus on ease of use. Optional extras available for this trim may include a sunroof, upgraded audio system, rear parking sensors, and a rearview camera. The S07 is offered with seating for either five or seven passengers, depending on the chosen configuration. The seven-seat version features a smaller cargo area when all seats are in use.
Chassis & Braking
The S07 1.5T utilizes a front-wheel-drive chassis. The front suspension employs an independent McPherson strut design with coil springs and an anti-roll bar, providing a balance of ride comfort and handling. The rear suspension features an independent multi-link setup with a stabilizer bar, further enhancing ride quality and stability. The braking system consists of ventilated discs at the front and solid discs at the rear. The ABS system helps to prevent wheel lockup during hard braking, improving safety and control. Tire size is 255/45 R20, mounted on 8.5J x 20 inch wheel rims.
Market Reception & Comparison
The Soueast S07 1.5T has been positioned as a competitive offering in the Chinese SUV market. Reviews have generally praised its modern styling, spacious interior, and relatively fuel-efficient engine. Fuel consumption is rated at 7.8 l/100 km (30.2 US mpg, 36.2 UK mpg, 12.8 km/l). While not a performance-oriented vehicle, the 1.5T variant provides adequate power for everyday driving. Compared to potential competitors, the S07 1.5T aims to offer a compelling value proposition, combining a reasonable price with a good level of features and equipment. Long-term reliability data is still emerging, as the S07 is a relatively new model. However, Soueast has been steadily improving its quality control processes in recent years.
