Keep your fuel costs down with the right car
Fuel-efficient cars reduce fuel consumption.
Gasoline prices in germany move the nation. Few topics are discussed as passionately as the ups and downs on the scoreboard at the gas station. Although fuel sellers are currently charging less for diesel, gasoline and the like than they have in a long time, the drop in prices on the crude oil exchange will not last forever and, in view of dwindling oil reserves, will lead to a reverse trend in the long term.
Fuel-efficient cars can reduce monthly expenses in this case. Many drivers are asking: which is germany’s most fuel-efficient car?? An economical car is a good idea, and not just for those who want to save money. A fuel-efficient vehicle also benefits the environment, will be less greenhouse gases and pollutants harmful to the climate how carbon dioxide and nitrogen oxides are blown into the atmosphere. An economical small car, for example, thus contributes to environmental protection.
How to recognize fuel-efficient small cars, which manufacturers offer particularly environmentally friendly models, and how the technology behind them works are all explained below.

FAQ: fuel-efficient cars
A list of different models can be found here.
The weight of the car plays an important role, but an aerodynamic design and thus a reduction in drag can also contribute to fuel economy. In addition, the tires, among other things, are also relevant.
Under real conditions, hardly any vehicle can achieve the values advertised by the manufacturers.
How is fuel consumption determined?
fuel-efficient cars are characterized by their aerodynamic shape.
If you are thinking of buying a new car and you want a car with low fuel consumption, you will usually rely on the manufacturer’s information on standard values.
This however, can seldom really be maintained in reality, even the most fuel-efficient cars still consume more fuel than specified.
The manufacturers test the consumption with the new european driving cycle (nEDC). This also determines the emission of pollutants. However, this figure rarely corresponds to the actual average consumption of the car. If you are interested in fuel-efficient cars, don’t just rely on fuel consumption figures.
They want to find out how much fuel their car uses and whether it is among the most economical? Then the fuel consumption per 100 km, the key parameter for comparing different vehicles.
The low energy vehicle (NEF)
vehicles that consume relatively little energy are also called low-energy vehicles. They consume significantly less fuel than the average fleet consumption.
A fleet can be defined as all vehicles of one brand, one manufacturer or one vehicle class.
Environmentally friendly cars consumption – related on a 100 km long distance – considerable less than five liters of gasoline or. 4.5 liter diesel. Under these conditions, no more than 120 grams of carbon dioxide per kilometer are emitted.
Fuel-efficient cars are often more expensive.
cars with such low fuel consumption are rarely seen on the roads, which is probably due to the high selling prices lies. They still discourage consumers from buying fuel-efficient cars. In addition, they not used to the aerodynamically shaped vehicles, why the sale of the fuel saver fails due to the aesthetic desires of car drivers.
Finally, many car owners prefer to use alternative fuels like E10 back or have their vehicle converted to natural gas in order to more climate-friendly to be on the road than to buy a new, fuel-efficient car.
How a fuel-efficient car must be built to consume less energy
If you want to save as much fuel as possible while driving, you can influence fuel consumption significantly through your own driving behavior. But certain features of the car itself also make it economical to drive.
With the help of fuel, the car must overcome the following resistances:
- air resistance (aerodynamics)
- Frictional resistance (z. B. In engine and transmission)
- inertial forces
- Rolling resistance
Depending on the situation in which the vehicle finds itself, these individual forces vary in magnitude. They can, however, be reduced through technical adjustments. This includes, for example, the use of tires with lower rolling resistance. During braking the tire deforms, in addition, the tread deformed. Hereby heat is generated and energy is lost.
Economical cars work, among other things, with tires whose rubber is specially compounded. This is achieved by adding special carbon blacks and silica, which increases grip on rain-soaked roads and minimizes rolling resistance. But also the adjustment of the tire substructure and a lower total weight of the car can help to consume less fuel.
An economical car has low rolling resistance tires that minimize rolling resistance.
The air resistance – also flow resistance called – is u. A. Reduced with the help of the vehicle’s shape, because aerodynamics have a decisive effect on whether or not a car is economical. The decisive factors here are both the cd value (drag coefficient) and the car’s frontal area. The higher these values are, the more the car is braked by the oncoming wind. This means: an economical car has a streamlined shape on and the occupants sit relatively low, so a gas station rarely has to be approached.
A phenomenon that slows down the progress of the vehicle are z. B. Resistance occurring in the front wheel arches. These can be reduced in fuel-efficient cars through technical adjustments. In addition aerodynamically adapted rims able to contribute its share to the car’s lower fuel consumption.
A car also consumes less fuel with the aid of so-called sail function. This usually comes with hybrid electric vehicles for use in which an electric motor is installed in addition to an internal combustion engine. sailing works as follows: the car continues to glide along with the engine switched off and disengaged, saving energy through the automatic start-stop system. An effect that is also noticeable at the gas station.
Which car consumes the least?
If you want to buy an economical car, you should find out which vehicle stands out for its particularly low fuel consumption values. Every now and then, consumer portals and trade journals check which current models are the most fuel-efficient cars. Therefore, it is best to obtain information from different sources beforehand about the respective different test results. Afterwards you can make an informed decision.
Which car consumes the least? Tests can provide information.
Last has AUTO BILD tested fuel-efficient cars in 2015. In the process, they determined the best fuel-savers in eight different classes, only selected ones of which are presented below, however.
In the category smallest car the stairs were distributed as follows
- 1. Place: škoda citigo 1.0 MPI green tec active (approx. 4,4 l)
- 2. Seat: seat mii 1.0 ecomotive style (ca. 4,5 l)
- 3. Place: fiat 500C 1.3 multijet 16V DPF lounge (ca. 4,6 l)
With the small car a renault came out on top. The ranking is as follows:
- 1. place: renault clio grandtour energy dci 90 start& stop luxe (ca. 4,3 l)
- 2. Place: ford fiesta 1.6 tdci titanium (ca. 4,6 l)
- 3. Place: mitsubishi space star 1.0 (approx. 4,7 l)
In the compact class a toyota worked its way to the top:
- 1. Place: toyota prius plug-in hybrid life (ca. 3,7 l)
- 2. Place: kia cee’d 1.6 crdi 128 spirit (ca. 4,6 l)
- 3. Place: nissan pulsar 1.5 dci tekna (ca. 4,8 l)
The most fuel-efficient car in the middle class currently represents a BMW, according to the results of the AUTO BILD test.
- 1. Place: BMW 320d efficient dynamic edition (ca. 4,6 l)
- 2. Place: opel insignia 2.0 CDTI ecoflex start/stop business edition (ca. 4,8 l)
- 3. Place: BMW 316d sport line (ca. 5 l)
The very same have nothing to do with the reality of most drivers’ lives, measure fuel consumption under laboratory conditions and at no more than 120 km/h, for example. When the freeway is open, many drivers drive much faster. This is also reflected in fuel consumption, even when driving an economical car.
Low-consumption cars can be returned if they consume more than the manufacturer has specified.
Did you, thinking that you were choosing a real fuel saver, go for a certain new car that is in hindsight, they proved to be much more fuel-efficient? Then you have under certain conditions the possibility of returning the car.
Because: due to the present material defect, they are entitled to a right of withdrawal from the contract of sale to. This includes that an expert proves this circumstance, however under the appropriate test conditions. This means that the values shown to you by the car itself are not recognized by the court.
Only an expert’s opinion is valid. Moreover, the buyer cannot always rely on the manufacturer’s specifications, as the car’s own driving behavior has a massive influence on the fuel consumption figures.
