Fuel consumption is an important concern among car users. There are predictions that futuristic cars will run on other substances. But for now, most cars need fuel to move an inch. It isn’t a one-off but a routine.
The more fuel your car consumes, the more money you spend. Hence, ensuring that your car consumes as minimal fuel as possible is of utmost importance. This gives rise to the question about fast driving and slow driving. Which one consumes fuel more? You’d like to know the answer to the question, wouldn’t you? Naijauto.com has your best interest at heart. That explains why we have put this piece together.
Fast driving vs slow driving in fuel consumption
There are some factors in a car speed that determine the quantity of fuel consumed. To arrive at a conclusion, it’s important to understand the variables involved and how they work. Without further ado, let’s unravel the mystery.
1. Upshot – slow speed
Right in every vehicle, lies the hub bulge that reflects the impact of car speed – slow, middle or fast on the quantity of fuel consumed by the car engine. An average engine does an RPM turning of 1,300. Despite enduring the low speed, the gear remains in the lower gear position.
Consequently, regular RPM spinning absorbs more fuel for every fuel consumption. By this explanation, slow driving isn’t always favorable for fuel management.
2. Efficiency of sweet spot in vehicles
Average speed is what’s referred to as sweet spot. It goes between the mph range of 30-50. Air resistance at this speed is low. This leads to transmissions that are high enough to attain substantial distance for each rev.
What this simply means is that it’s easier for the car to arrive at the middle when it moves at low speed on high load road. There are a number of factors responsible for road load. They include:
- Quantity needed to drag the tires: Big cars like SUVs have higher weight than the smaller ones.
- Frontal area: The frontal area is determined by the car size. The bigger the car, the bigger the frontal area, and vice versa. This explains why the frontal area of SUVs is way bigger than that of smaller cars.

Fast driving often consumes more fuel but it's not always the case
3. Fast speed fuel consumption
Cars are often made to move on high speed – that’s how you get to your destination on time. However, when you move on high speed, the transmission attains the higher gear modes, creating chances for a 1000 – 3000mph glide. However, it’s possible for the locomotive to disseminate a little quantity of revs/m, using little fuel.
Air opposition is small while moving slowly but increases up to four times when you double each speed. Hence, the engine has to work harder in order to survive the air resistance. As a result of this, there’s a reduction in the mileage in line with the increment in velocity. In regard to this, fast driving consumes more fuel.
Fast driving takes more fuel especially due to energy consumed in taking up haul that increases along with the speed. However, in various cars, a threshold is set as the burning up increases. The average car on the road today hits this threshold at about 120kmph. Same cannot be said for stronger and higher cars because they have a higher threshold.
To answer the question: Do fast driving cars consume more fuel than slow driving cars? None of them is the better option. Moderate speed takes the cake. Don’t go too fast and don’t go too slow. Not only will you be protecting yourself from the dangers of high speed, you’ll also be saving up some money when you stay in the middle.
