How to get to the nearest gas station or fit into the trip budget.

At this speed, the car is maximally economical

< p>Let's start with the fact that it makes no sense to focus on the efficiency indicators specified in the vehicle specifications and car manuals. It happens that the data given in such documents only come close to the values ​​of real costs, informs Ukr.Media.

However, in most cases, the "documented" a liter, several liters, or even double the literage should be added to the parameter, if the movement is carried out in a large and heavy four-wheel drive car, in adverse conditions (traffic jams, off-road driving, in low gear, etc.).

Why are there such discrepancies? The fact is that any of the methods for calculating consumption is carried out in greenhouse conditions, namely, on stands, where the car only simulates acceleration, braking and acceleration, typical for driving outside the city, in the city and in a mixed mode.

For example, according to the standards of the European evaluation methodology, the consumption results for urban conditions are removed when the car accelerates to 50 km/h in an endless 26 seconds. At the same time, stops in front of a traffic light and an invariably leisurely set of speed are also simulated. When evaluating the parameters of movement in a mixed cycle, movement at a speed of up to 70 km/h is taken as the starting point. At the same time, all power consumers are turned off in the car and tires with the minimum allowable tread are used to reduce frictional energy losses.

It is clear that in real conditions it is problematic to follow this manner of driving – you will interfere with other traffic participants, and it is unlikely that you will be able to maintain an even pace of driving, which contributes to economy. The same applies to driving without the lighting equipment and air conditioner turned on – at night and in the heat, driving like this is unlikely to work.

However, if you are faced with the task of saving fuel as much as possible, then the speed mode of 75 km/h will be optimal. To keep such a speed in the city in the absence of traffic jams, by the way, is quite realistic, if the speed limits allow. As for the speed-setting algorithm, for maximum economy, you should start as the testers do on the stand — accelerate to 50 km/h in the same 26 s and at the same time make sure that the tachometer needle does not climb above the 1500 rpm mark.< /p>

On the track, for maximum economy, you will have to move to the far right row and maintain a cruising speed of 75-80 km/h ideally, if you manage to get behind the same slow-moving vehicle (a truck, a cargo van, a grandfather on an old “zhiguly” #34; etc.). Then it will be possible to reduce fuel consumption to a large extent due to the reduction of frontal drag.

Another important point is related to choosing the right gear in the transmission. It is preferable to activate the highest, direct gear, for which in the case of automated boxes it may be necessary to activate the manual mode. If possible, switch "up" without delay, for example, immediately after "second" include "fourth" and make sure that the tachometer needle remains at low speeds.

At the same time, if driving conditions allow, it will not be superfluous to turn off the climate control unit and other powerful consumers of electricity, which will also contribute to the economy of driving. Yes, working headlights require an additional 0.5 l/100 km, so it is better to use daytime running lights or fog lights during daylight hours. Another life hack is to increase the pressure in the wheels by 0.2 bar – this way you can expect to reduce fuel consumption.

In any case, remember that “vegetable” the manner of driving will surely cause irritation in the neighbors on the stream. Therefore, let's repeat, stay in the slow-moving right row.
