What is the actual fuel consumption at maximum speeds? What is the actual fuel consumption at maximum speeds?

When the driver has a heavy foot, the fuel sellers rub their hands contentedly. Fuel consumption in cars running on highways at full throttle is dizzying.

To reduce fuel consumption, car manufacturers use various tricks like downsizing, reducing the number of cylinders, using lighter materials. Basically, all this brings the expected results. For example, diesel engines are increasingly consuming almost 4 l / 100 km. However, it should be noted that the lowest consumption is achieved in ideal conditions, where none of the tested cars accelerated over 120 km / h.

However, in practice it is completely different. The more often you press the accelerator pedal to the floor, the higher the fuel consumption. So, all the manufacturer's data goes to the sky, even if the car is driven at the allowed speed. Cars have to fight air resistance and rolling. Vehicle weight also plays a big role.

It’s good to remember that the faster you drive, the higher the air resistance. This is important because the maximum values ​​of power and speed increase with each new model. Today, in compact engines with a mediocre engine, you can easily drive 200 km / h.

AutoBild reporters selected 10 cars that they chased with the left lane of a German highway with the right pedal pressed to the floor. See below how greedy the tested cars were.

 Mercedes G 500

Mercedes has created a real monster. The G 500 is equipped with a powerful 387 hp engine and 530 Nm of torque. Under full throttle, it consumed 62.3 liters per 100 kilometers


The result achieved in the BMW M5 is 62 l / 100 km

Audi A8

The trip computer reports that the fuel consumption is 32.9 l / 100 km. But don't trust him. In fact, the Audi A8 consumes 36.6 l / 100 km


If the driver has a heavy leg, the X5 50i will consume more than 49 liters of fuel per 100 km on the motorway

Fiat Ducato

With the gas pressed to the floor, the Ducato consumes 17.9 l / 100 km

Jaguar XFR-S

If you were to drive at top speed all the time, the fuel in Jaguar’s tank would only last 112 kilometers. The Jaguar XFR-S consumes 62.5 liters of gasoline per 100 km at top speed

Golf 7

The VW Golf 2.0 TDI consumed over 14.5 l / 100 km of diesel while driving at full throttle.

Mazda 3

The two-liter, four-cylinder Mazda 3 engine burns 22.2 liters of gasoline in the exhaust after 100 km

Škoda Octavia 1.2 TSI

The 105 hp Škoda Octavia 1.2 TSI consumed 13.4 l / 100 km in the test

If you really want to save fuel, take your foot off the accelerator pedal. Without this, no technical trick used by car manufacturers will help reduce fuel consumption.
