The fuel consumption performance of the Leapmotor C11 varies by powertrain version. The extended-range version has an official fuel consumption of 5.2L/100km (WLTC cycle) when battery-depleted, with real-world measured consumption averaging 5.8-6L/100km (using 92-octane petrol). The pure electric version operates solely on electricity, with typical energy consumption ranging from 13-18kWh/100km, reducible to 9.9kWh/100km in efficient driving mode (urban commuting). Its CLTC range realization rate reaches 82%-84%, though consumption may increase slightly to 15-18kWh/100km in cold winter conditions. The extended-range version combines a 1.5L Atkinson cycle range extender with a 94.3% efficient motor, enabling seamless fuel-electric transitions. With a 300km pure electric range sufficient for daily commutes, the per-kilometre electricity cost drops to 0.06-0.07 MYR when home-charged. For annual mileage of 20,000 km (80% electric/20% fuel), total energy costs approximate 3,000 MYR - merely 25% of comparable fuel vehicles. Enabling strong regenerative braking and maintaining tyre pressure at 2.5-2.7Bar further enhances efficiency.
