Powertrain & Engine Architecture

The Stelato S9T utilizes a single, rear-mounted synchronous electric motor producing 309 horsepower and 396 Nm (292.07 lb.-ft.) of torque. This motor, designated TZ210XYA03, is powered by a 100 kWh lithium-nickel-manganese-cobalt oxide (Li-NMC) battery pack located under the vehicle floor. The 800V architecture allows for rapid charging capabilities, significantly reducing charging times compared to older 400V systems. The single-speed automatic transmission is a direct-drive unit, typical of electric vehicles, maximizing efficiency and providing seamless acceleration. The battery management system (BMS) is crucial for optimizing battery life, performance, and safety, constantly monitoring cell voltages, temperatures, and overall health.

Driving Characteristics

The rear-wheel-drive configuration of the S9T contributes to a balanced driving experience. Acceleration from 0 to 60 mph is achieved in approximately 5.6 seconds, and 0-100 km/h in 5.92 seconds. While not a performance-focused EV, the instant torque delivery of the electric motor provides brisk acceleration in everyday driving situations. The single-speed transmission offers a linear power delivery, without the gear changes associated with internal combustion engines. The air suspension, standard on the S9T, provides a comfortable ride quality, absorbing road imperfections effectively. The relatively low center of gravity, due to the battery pack’s placement, enhances stability during cornering.

Equipment & Trim Levels

The Stelato S9T comes standard with a comprehensive suite of features, reflecting its premium positioning. Interior appointments include high-quality synthetic leather upholstery, a large touchscreen infotainment system with integrated navigation, and a digital instrument cluster. Standard safety features include ABS, traction control, stability control, and a suite of advanced driver-assistance systems (ADAS) such as automatic emergency braking and lane-keeping assist. Optional extras include a panoramic sunroof, premium audio system, and ventilated front seats. The interior design emphasizes minimalism and functionality, with a focus on creating a spacious and comfortable cabin.

Chassis & Braking

The S9T features a double wishbone suspension setup at the front and an independent multi-link suspension at the rear, both incorporating a transverse stabilizer bar and air suspension. This configuration provides a good balance between ride comfort and handling. Ventilated disc brakes are used on all four wheels, providing ample stopping power. The electric regenerative braking system captures energy during deceleration, increasing efficiency and extending range. The steering system utilizes an electric power steering (EPS) system, offering precise and responsive steering feel.

Market Reception & Comparison

Initial reviews of the Stelato S9T have been positive, with critics praising its long range, comfortable ride, and spacious interior. The 801 km (497.72 mi) range is competitive with other long-range EVs in the market. Fuel economy is rated at 13.5 kWh/100 km (21.73 kWh/100 mi), translating to 155 MPGe. Compared to potential competitors like the Tesla Model Y Long Range or the Polestar 2 Long Range Single Motor, the S9T offers a compelling combination of range, practicality, and value. Some reviewers have noted that the infotainment system could be more intuitive, and the brand lacks the established reputation of its rivals.

Legacy

The long-term reliability of the Stelato S9T powertrain remains to be seen, as it is a relatively new vehicle. However, the use of proven Li-NMC battery technology and a robust electric motor design suggests good durability. The 800V architecture and advanced battery management system should contribute to extended battery life. As the used car market matures, the S9T is expected to hold its value well, particularly among buyers seeking a practical and efficient electric station wagon. The S9T represents a significant step forward for Stelato, establishing the brand as a serious contender in the rapidly evolving electric vehicle landscape.
