Geely has unveiled the Thunder 16-in-1 intelligent electric powertrain, developed by its subsidiary InfiMotion. According to the manufacturer, the system provides a combined efficiency of 93.8%, which is a record for production solutions.
The main feature of the new product is its high degree of integration. Twelve hardware components are combined in one module, including an electric motor, inverter, gearbox, power converters, battery and vehicle control units, and a thermal management system. In addition, four software functions are implemented: intelligent energy management, charging, driving dynamics, and powertrain technical condition.
Thanks to this architecture, the developers were able to eliminate more than 180 individual components. The system's power density reaches 11.8 kW/kg, and its mass is 75 kg, which is approximately 15% less than most similar solutions. The length of high-voltage wiring has also been reduced by 30%, and low-voltage wiring by 15%. The compact design, with a height of less than 325 mm, has increased trunk volume by approximately 28 liters.
The powertrain is designed to work with an 800-volt architecture and is equipped with One-Chip technology, which reduces command processing delay from the usual 40 ms to 2 ms, increasing vehicle response speed.
During tests around Qinghai Lake, a car with the new drive demonstrated energy consumption of 8.2 kWh per 100 km. In the standard CLTC cycle, the declared consumption starts from 10.7 kWh per 100 km. The manufacturer also reports that AI-based algorithms optimize system operation in low temperatures and at high speeds. At –18 °C, the unit can accumulate about 7 kWh of thermal energy, which reduces energy consumption for cabin heating by more than 40%.
The first car with the new powertrain is the Geely Galaxy TT electric sedan, which debuted in July. The 4999 mm long model with a 2920 mm wheelbase is offered in two versions: a rear-wheel drive with 245 kW (329 hp) and an all-wheel drive with 425 kW (570 hp), which accelerates to 100 km/h in 3.8 seconds.
For the Galaxy TT, batteries with capacities of 52.4, 63.8, and 75.2 kWh are provided. Depending on the modification, the range according to the CLTC cycle ranges from 540 to 725 km.
