Extremely fuel-efficient. The X-Trail e-POWER has an outstanding WLTC combined fuel consumption of 18.4 km/L. For a 2-tonne, 204 hp 7-seat SUV, this is exceptional. Realistically, you can expect about 15-17 km/L in the city and 20-22 km/L on the highway, resulting in a fuel cost of approximately HK0.9to0.9to1.1 per kilometre.
