There is a difference between the 4th and 5th gears of the Refine M3 transmission. Here are the specific details: 1. The 5th gear is more fuel-efficient than the 4th gear: According to the engine response characteristic curve, the most fuel-efficient part only occupies a small portion of the curve. The more gears a transmission has, the easier it is to keep the engine operating in the most fuel-efficient state. Therefore, theoretically, the 5th gear is more fuel-efficient than the 4th gear. 2. The 5th gear offers better shifting quality than the 4th gear: For the same vehicle, to adapt to various working conditions such as climbing and high-speed driving, the highest and lowest gears of the transmission are fixed. The ratio range is obtained by dividing the highest gear by the lowest gear. The more gears there are, the smaller the intervals between each gear, resulting in less shifting impact and better shifting quality.
Experienced drivers of the JAC Refine M3, let's talk about gear experience. 4th gear is a direct drive gear, particularly effective around 70km/h, with quick throttle response for decisive overtaking; shifting up to 5th gear noticeably lightens the engine sound, reducing RPM by at least 500, making it especially fuel-efficient on highways. In the city, 5th gear is hardly ever needed—if the speed isn't sufficient, engaging 5th gear feels like an ox dragging a cart. I once tried climbing a gentle slope at 60km/h in 5th gear, and the engine shook so much it was unnerving. The key is speed: 5th gear's advantages only kick in above 80km/h, where fuel consumption can drop by 20%. When fully loaded and climbing, you must downshift to 4th gear for enough power, or the transmission will protest. Mastering gear shifts is all about experience.
