Geely has introduced a new EV motor that combines most of the hardware and software needed for an electric drivetrain into a single, compact unit. The “Thunder” system cuts high‑voltage wiring by roughly 30 % and low‑voltage wiring by about 15 % compared with traditional setups, according to the company’s release.
Integrated design trims weight and size
The drive unit weighs 165 pounds (75 kg) yet delivers 328 horsepower in its single‑motor configuration. The enclosure is built from magnesium and stands just 12.8 inches (325 mm) tall. By integrating twelve components—motor, motor controller, DC‑to‑DC converter, on‑board charger, vehicle control unit, active pre‑charge controller, low‑voltage and high‑voltage battery management systems, and power domain gateway—into one housing, the firm eliminated more than 180 separate parts.
That consolidation translates to a power density of 11.8 kilowatts per kilogram. The reduced wiring and component count free up to one cubic foot (28 liters) of trunk space that would otherwise be occupied by conventional drive‑system hardware. The system’s efficiency reaches 93.8 %, a figure described as a production‑level record in the industry.

First application appears in Geely Galaxy TT
The inaugural vehicle to use the “Thunder” drive is the Geely Galaxy TT, marketed as an electric sports sedan. Its single‑motor version produces the same output, while a dual‑motor all‑wheel‑drive variant reaches 570 horsepower. The car runs on an 800‑volt architecture and can be equipped with battery packs of 52.4 kWh, 63.8 kWh, or 75.2 kWh. The company lists a maximum CLTL range of 450 miles (725 km) for the top‑end configuration.
Beyond the raw numbers, the compact drive could influence vehicle packaging decisions across the market. Automakers that struggle with limited interior space may find the reduced footprint attractive, especially for models that prioritize cargo capacity without sacrificing performance.
The real test will be how the integrated system performs over time and under varied operating conditions. If efficiency and durability hold up in real‑world use, other manufacturers might adopt similar consolidation strategies to stay competitive. However, the long‑term reliability of housing so many functions in a single magnesium case remains to be proven, and service networks will need to adapt to new diagnostic and repair protocols.

Geely’s announcement comes as the global EV market continues to expand, with many players seeking ways to lower vehicle weight and improve efficiency. The “Thunder” drive’s claimed 15 % weight advantage over comparable mainstream units could help shave energy consumption, potentially extending range without increasing battery size. Yet, the actual impact on consumer‑level pricing and overall vehicle cost is still unclear, as the integration may shift expenses from parts to more complex manufacturing processes.
Industry observers note that the move toward highly integrated drive units aligns with broader trends toward modular vehicle platforms. By reducing the number of separate components, manufacturers can streamline supply chains and simplify assembly lines. This could also lower the environmental footprint of production, though the extent of such benefits depends on the sourcing of magnesium and the recyclability of the integrated system.
