Power output varies depending on the hybrid system but typically delivers around 77–82 kW (104–110 hp) from the petrol engine alone, working alongside an electric motor for a combined system output that can exceed 169–171 kW, depending on the model. 

The engine utilizes a timing chain, high-efficiency cooling, integrated exhaust manifold, and Smartstream low-friction technologies designed to reduce wear and improve longevity.

Common Weaknesses & Maintenance Notes.

While the G4FT hybrid engine is highly reliable, a few maintenance areas should be monitored. The high-pressure fuel system may experience injector buildup over high mileage, making periodic cleaning essential. 

Hybrid engines rely heavily on proper cooling, so maintaining coolant levels and monitoring the water pump is important. Some units may develop EGR or intake valve deposits due to direct injection, requiring occasional cleaning for optimal performance. 

Electric-motor integration also means that hybrid system sensors and battery cooling components should be checked regularly. With consistent servicing and high-quality oil, the G4FT engine provides long-lasting, trouble-free hybrid performance.
