The evolution in the engines of current vehicles has led brands to offer cars with lower consumption, in relation to what their older brothers spent. An evolution that reduces fuel costs and helps improve the environment.
Currently, the goal of vehicle manufacturers is to reduce CO2 emissions from cars to a minimum, while maintaining high power and good road performance. An approach where they all compete to offer the best possible diesel or gasoline engine, to place their model among the least polluting cars on the market. If you are thinking of buying a car with reduced gasoline consumption or a diesel that really saves, we reveal to you which are the 10 cars that consume the least on the current market.
The Hyundai Ioniq always stands out in any comparison of plug-in hybrids for its good consumption data. This car has a 141-horsepower gasoline engine and an 8.9-kw battery electric motor. The result is an official consumption of 1.1 liters, with an electric range of 63 kilometers. However, if you run out of power, you always have the combustion engine, to keep you moving.
The Kia Niro is the twin brother of the Hyundai Ioniq that we just mentioned and is among the least consuming SUVs on the market. However, despite their similarities, their consumption rises a bit, up to 1.3 liters per 100 kilometers.
3. Mercedes A-Class
The plug-in hybrid version of the Mercedes class A is another of the models that we highlight. This version has 218 horsepower in its gasoline engine, along with another 102-horsepower electric motor. The result is a vehicle with the brand’s own response and an approved consumption of just 1.5 litres.
4. BMW 330e
We continue within the high range to talk about the BMW 330e. Another plug-in hybrid capable of reaching 292 horsepower, through the XtraBoost function. All this with a consumption of just 1.7 liters per 100 kilometres, so it is obvious that this vehicle is never lacking when we talk about the low consumption cars of the moment.
5. Mercedes E 300 DE
The Mercedes E 300 DE model breaks the trend of this comparison. And not because it is not a plug-in hybrid, but because it is one of the diesel cars that consume the least, within its segment. This vehicle has a total power of 306 horsepower, 194 from the diesel engine and 122 from the electric one, leaving consumption at 1.7 liters per 100.
6. Citroën C5 Aircross
If you need space for your suitcases or you want to go camping with your tent, any of the Campingaz barbecues on the market and the rest of what you need to enjoy, this choice is for you. The Citroën C5 Aircross is an agile SUV on and off the road, keeping consumption at bay thanks to a 225-horsepower electric motor and a booster gasoline engine. A mixture that hardly spends 1.7 liters per 100.
7. Volkswagen Golf GTE
Among the powerful small cars in our selection, we have the Volkswagen Golf GTE. A vehicle that has an approved consumption of 1.8 liters at 100 and a power of 204 horses. If that sounds like a lot to you, the new generation of this model, already in design, will reduce consumption thanks to an even more powerful motor and a larger battery, with a capacity of 13 Kw.
8.Mitsubishi Outlander PHEV
Although it may seem surprising, this large SUV of the brand has a consumption of just 1.8 liters per 100. Something to which a 230-horsepower electric motor contributes, with good-sized car batteries, supported by a gasoline engine of 2.4 liters and 135 horses.
The presence of the BMW i8 is another interesting surprise. We are talking about a supercar that mounts the plug-in hybrid technology that we have been discussing and that has an approved consumption of 1.9 liters. However, if you want to squeeze its 374 horsepower, surely the real consumption is much higher.
We close the list with another BMW, the i8. This compact MPV has an approved consumption of 2 liters, a good interior space and all the sporty character of the brand. In fact, the declared power of the vehicle is no less than 224 horsepower.
How to calculate the consumption of a car
Before getting into the matter, it is convenient to know the procedure used to calculate the cost of gasoline per kilometer of a vehicle, whether you want to make that calculation on your own vehicle or if it is done professionally. Situations that differ, as we will see below.
When it comes to executing this calculation when homologating engines, a series of running-in tests are carried out. This test is carried out on a roller machine, where the vehicle circulates about 11 kilometers in the “city”, at an average speed of 19 kilometers per hour, and another 7 kilometers on the motorway, at high speed. The result of the test is the approved consumption of the engine.
However, this test is anything but realistic. Let’s think that in it there are 12 stops of traffic lights in about 20 minutes, which are surely few for a shoot in the city. In addition, on the motorway part, it hardly drives at 120 kilometers per hour, the normal speed on these roads.
This causes that the result of the test has little to do with the real consumption of cars on the street. Some real figures that are easy to calculate and, in addition, adapt to your specific use. To do this, fill the car’s tank, set the on-board computer to 0 and record the distance traveled in normal use. For the test to be representative, it is recommended to travel at least 200 kilometers.
Once you’ve completed the route, which you don’t have to do all at once, go back to the gas station and fill up the tank. Write down the mileage traveled and check how many liters you add to the tank to fill it up again. With these data, we only have to divide the mileage between the liters refueled on this second occasion, multiply the result by 100 and we will immediately obtain the data that allows us to know if our vehicle is among the cars that consume the least and to be clear about what it is your actual fuel cost.
