Just picked up 2024 Ram 1500 e torque sport. currently 400km on it. On my first drive on the hwy i got arround 15L per 100km average fuel economy, somewhat normal driving (10.5Lper 100km as per Factory). Sims to run on higher rpms, little over 2000 on speed of 100km/h .i drove 2023 classic before and the rpms where around 1500. Any suggestions?
