For a long time, how to drive to save fuel has become a topic of concern for many drivers. Many factors such as model design, displacement size, road conditions, vehicle conditions, vehicle speed, driving Xi, fuel quality, vehicle maintenance, and vehicle environment may affect fuel consumption. However, among these factors, the impact of personal driving Xi on the fuel consumption of a car is particularly obvious, and may even lead to a difference of 10%-30%.
Take the Cadillac CT6 as an example, which is a 2The 0-liter turbocharged model produces 276 hp. According to the experience of a veteran driver with 15 years of driving experience, he found that the average fuel consumption of his CT6 is about 11 liters when driving in the city, and as low as 5-6 liters per 100 kilometers on the highway. However, when his wife took over the drive, fuel consumption in the city skyrocketed to 135 liters. After a comparative analysis, they found three main driving Xi that led to an increase in fuel consumption.
First of all, the throttle is not properly controlled when starting, overtaking, and climbing. If the throttle is too big or too small, it will increase fuel consumption. For example, in a turbocharged model, the turbo intervenes when the engine speed exceeds 1800 or 2000 rpm. If you press the accelerator too much at the start, it is easy to trigger the turbo intervention, which will increase fuel consumption.
Secondly, it does not predict the road conditions and brakes frequently. Novice drivers often have difficulty controlling the throttle accurately, resulting in sharp braking and deceleration. For example, seeing that there are only a few seconds left at the traffic light ahead and there are still vehicles ahead of them, some novices will choose to brake early and drive slowly. Not only does this waste of fuel, but it can also lead to traffic congestion.
Finally, the incorrect "one step and one loose" driving style. Although some veteran drivers will recommend the "one pedal, one loose" method to save fuel, if this method is not used properly, it may increase fuel consumption. On the highway, for example, driving at a constant speed is more fuel-efficient than accelerating and decelerating frequently.
As for the relationship between vehicle speed and fuel consumption, there is no absolute fuel economy. Generally speaking, the vehicle is kept at a constant speed of 60 km/h without load, which may be an economical speed for small and medium-displacement vehicles. However, for large displacement models, such as 2The 0-t turbo model, driving at 60 km/h on city roads, may have an engine speed of 1,600 rpm, which leads to higher fuel consumption.
Therefore, in order to save fuel, we need to adjust the speed and throttle in a timely manner according to factors such as vehicle type, load, displacement, road conditions, etc. On the highway, the speed can be maintained in the range of 95-105 km/h, which ensures safety and is relatively fuel-efficient.
In addition to driving Xi habits and speed, factors such as vehicle maintenance, vehicle condition, and fuel quality can also affect fuel consumption. For example, changing oil and filters regularly, avoiding poor quality fuel, and paying attention to tire pressure can help us reduce fuel consumption.
To make a car more fuel-efficient, we need to consider a variety of factors and adjust our driving habits in Xi right time. Although we can't be absolutely fuel-efficient, the difference in fuel consumption between an experienced veteran driver and a newbie can sometimes be as high as 30% or more. Therefore, it is important to develop good driving Xi. Every day, I will share some tips about how to use the car, if it is useful to you, please like it and pay attention to it.
