Prius and fuel consumption - myths and reality
Many are interested in the vital question - how economical is the Prius in actual use?
The manufacturer declared a fuel consumption of 35.5 km / l or 2.81 l / 100 km. Hmm, tell me, you never know what they write in advertising booklets and you will be right. It is possible in ideal conditions, etc., etc.
By the way, Grand Touring trim levels are slightly more expensive than others - apparently due to R16 wheels. The difference in the catalog: G - 33 km / l (3.03 l / 100km), S - 35.5 km / l (2.81 l / 100km).
Therefore, I decided to conduct some tests, since the conditions are good now - summer has come. It is foolish to measure fuel consumption in winter, but more on that.
And so, we break Toyota’s factory record - on a track of 7 km, the consumption amounted to 38.1 km / l or 2.62 l / 100km, the driving time is 15 minutes, all these data are visible in the first photo. By the way, the measurement was made spontaneously, in city traffic, there was a pushing in the traffic jam too, gasoline 92, the EV mode did not turn on, the climate was set to 23 degrees, the air conditioning was turned on.

Think this is the limit? I can easily make a consumption of 99 km / l or 1.01 l / 100km on a plot of up to 3 km, see the second photo. Why am I focusing on the run? The fact is that in EV mode (electric car) the Prius runs an average of 3 km, therefore, so that there is no doubt and for the purity of the experiment, in the future we pay attention to mileage.
In general, the result of 39 km / l on a section of the path of 10 km is quite real, which has been checked more than once. But like everywhere else there are “buts” - the movement is as uniform as possible, with smooth acceleration, more often than usual we release the gas pedal to quickly turn off the gas engine, speed 40-66 km / h. How often do you ride in the front row for a slow boat? Exactly.
The third photo was taken this morning and it is more suitable for estimating the average consumption: 24 km / l or 4.16 l / 100km with a run of 59 km. On average, I now have a consumption of up to 4.5 l / 100 km with a calm, rhythm-free ride with few overtaking in urban traffic, naturally with morning traffic jams. I think this figure should be calculated when planning fuel costs. The survey statistics of my friends Prius owners confirmed this assumption.
Well, in order to dispel all doubts and thoughts - the fourth photo was taken from the Japanese instruction manual, where I accidentally noticed the following data: 20.5 km / l (4.87 l / 100km) mileage 520 km and 24.6 km / l (4.065 l / 100km), by the way, you can immediately pay attention - what is the difference between a restyled display (left) and a restyled display (right).
And what about fuel consumption in winter? This question arises among many skeptics.
Answer: In winter, the consumption directly depends on the ambient temperature, or rather, on the temperature in the cabin. The fact is that Prius heating is liquid and heat is taken from the cooling system of a gasoline engine. In order for the cabin to become warm, the gasoline engine will consume fuel (do not turn off) even if the traction battery is fully charged. The duration of the intervals of the gasoline engine will depend on the minus on the street and the desired temperature set in the climate control in the cabin. If you want to save fuel - we are cold, we want heat - we pay.
And now for the numbers - the average winter consumption in the city with a climate of +23 was about 7 l / 100 km. In cold weather for -30 (this year the minimum was -42), the maximum flow rate increased to 9-10l / 100 km. Is it a lot or a little?
If we compare with the second machine (Mazda Demio, 1.5 liter volume, 113 hp, 2002 release, automatic transmission), which is operated in parallel, then the fuel consumption at medium temperatures (-20 -25 degrees) is about 1.5- Prius has 2 times less, and this is with the significantly larger dimensions and weight of the Prius. This fact, joyful to me, was noted by the increased refueling intervals. The fuel tank of the Prius and Demia is the same - 45 liters.
For reference: I always warm up the Prius in winter and do not start moving until climate control starts supplying warm air to the passenger compartment. A Mazda Webasto boiler is installed on the Mazda (hourly fuel consumption of 0.5 l / h) with winter heating in the mornings and evenings for 30-40 minutes.
People often ask: How are things on the track? They say the Prius is a city car and is designed for standing in traffic jams.
Answer: In winter I traveled to Komsomolsk-on-Amur, about 900 km of journey came back and forth with trips around the city, the temperature along the road reached -30. Fuel consumption, depending on the speed of movement, varied from 6 to 7.2 l / 100km. I must admit that the high flow rate of 7.2l / 100km due to the high speed. He “flew” home as much as the road allowed and did not pay attention to profitability. Several times reached a maximum speed of 170 km / h - then excuse me, cut-off.
If you want the minimum expense on the highway, then be sure to use cruise control. But there is a limitation - cruise control operates up to 110 km / h.

Everything Toyota Prius car models have engines with two volumes - 1.5 and 1.8 liters, each of which has its own characteristics. This data can help you choose the machine you want.
|Engine||Consumption (highway)||Consumption (city)||Consumption (mixed cycle)|
|1.8 Hybrid||2.9 l / 100 km||3.1 l / 100 km||3 l / 100 km|
The main technical indicators about cars with a 1.5 liter engine.
- Engine power is 77-78 hp
- The maximum speed is 170 km / h.
- Acceleration to 100 km is carried out in 10.9 s.
- Fuel injection system.
- Automatic transmission.
The characteristics of the improved Toyota Prius model with a 1.8 liter engine look different, which significantly affects fuel consumption on the Toyota Prius. In the modifications of this machine, the engine power is 122, and in some 135 horsepower. This affects the maximum speed, which increased to 180 km / h, while the car accelerates to 100 km in 10.6 s, and in some cases in 10.4 seconds. Regarding the gearbox, all models are equipped with an automatic option.
All of the above data affect the fuel costs of Toyota Prius and general information about them is as follows.
Cars with a 1.5 liter engine
The average fuel consumption of a Toyota Prius with this version of the engine in the urban cycle is 5 liters, in the mixed - 4.3 liters and in the suburban cycle does not exceed 4.2 liters. Such information on this model has reasonable fuel costs.
Regarding real data, they have a slightly different look. Total Toyota Prius gasoline consumption on the highway is 4.5 liters, mixed-type driving consumes about 5 liters, and in the city the figures increase to 5.5 liters per 100 km. In winter, consumption increases by 1 liter, regardless of the type of ride.
1.8 liter cars
The new models, modified by increasing the engine size, show, respectively, other figures for fuel costs.
Owners of cars of this class post a lot of different information and reviews on fuel consumption and numbers on it. Therefore, the real fuel consumption on the Toyota Prius Hybrid in the urban cycle increases to 5 liters, in the mixed - 4.5 liters, and on the highway about 3.9 liters per 100 km. In winter, indicators increase by at least 2 liters, regardless of the type of ride.
Cost Reduction Techniques
The fuel consumption of an engine depends on many factors that affect the operation of all vehicle systems. The main ways to reduce the cost of gasoline in the Toyota Prius include:
- driving style (smooth driving and slow braking would be better than harsh and aggressive riding),
- reducing the use of various electrical appliances in the car (air conditioning, GPS-navigator, etc.),
- “Consumption” of high-quality fuel (refueling with bad gasoline, there is a high probability of increasing fuel costs),
- Regular diagnostics of all engine systems.
One of the main criteria that affects the fuel consumption of Toyota Prius per 100 km is winter driving. In this case consumption increases due to additional warming up of the car. Therefore, when choosing this model of machine, you need to consider all these factors.
