Comparison of naturally aspirated and turbocharged engines. Naturally aspirated or turbocharged, that is the question

Before purchasing a car (and it does not matter the first or next, new or used), each potential buyer faces a choice: which engine (if we are talking about a gasoline power unit) to choose - atmospheric or turbocharged. In this matter, a lot depends on personal preferences (that is, driving style), operating conditions and planned costs for its maintenance. Both varieties automobile motors have as their undeniable merits, and, of course, a number of shortcomings. Therefore, it is impossible to give a definite answer which engine is better. In our article, we will try to give comparative characteristic the main technical and consumer indicators of both motors.

Briefly recall how it works Gas engine:

• Air-fuel mixture through inlet valve enters the cylinder.
• Then it is compressed and ignited with a spark plug.
• After ignition, the energy of the so-called "microexplosion" is transferred to the piston.
• The gases resulting from the combustion of the mixture are then discharged through the exhaust valve.

The main differences between atmospheric and turbocharged engines

To say that atmospheric (that is, standard) and turbocharged engines is fundamental different motors, it is forbidden. The design and principle of operation of both units are largely similar. What is their difference? At standard motor air is sucked into the cylinder through the intake valve at atmospheric pressure. In a turbocharged engine, it is pumped under much higher pressure, which creates special device- turbine. For its rotation use the energy of exhaust gases from exhaust manifold. Structurally, the turbocharger consists of two isolated impellers mounted on one shaft.

Exhaust gases, coming from the exhaust manifold to the so-called "hot" blades, spin the turbine shaft. The rotating "cold" impeller picks up air and forces it under pressure into the cylinder. Since the turbine housing is heated to significant temperatures by hot exhaust gases, between the compressor and intake manifold install a special radiator - intercooler. Lowering the charge air temperature increases its density, resulting in a richer air-fuel mixture. With the same cylinder volume, a turbocharged engine burns much more in one cycle. fuel mixture, which means more energy is released. It is due to this that they significantly exceed atmospheric counterparts in terms of power.

For information! Since all internal parts of turbocharged engines experience significant mechanical and thermal loads during operation, more wear-resistant and heat-resistant materials are used for their manufacture. Because of this, the cost of the entire unit as a whole increases.

Pros and cons of naturally aspirated engines

The undoubted advantages of atmospheric engines include:

• The simplicity of the design, which has been proven in practice for many decades. Repair and Maintenance such power units cost the owner much cheaper (compared to similar operations for a turbocharged engine).
• Much greater resource uninterrupted operation before overhaul. At right conditions operation and proper maintenance, the “life” of atmospheric engines is 2–4 times longer than that of turbocharged engines: 300,000–400,000 km are often not the limit of the “longevity” of such engines.
• Less oil consumption, which, depending on the driving style, usually does not exceed 200÷500 ml per 10,000 km of the vehicle run. This is due to the absence of additional devices that require lubrication, as well as the lower loads experienced by the rotating parts of the motor during operation.
• Unpretentiousness to the quality of the oil used. They work quite satisfactorily on semi-synthetic (and even mineral) motor oils. However, one should not forget that what better oil, topics longer term engine service.
• Not as frequent as for turbocharged engines, the frequency of oil changes, which must be done after a run of 15,000 ÷ 20,000 km.
• Less demanding on the quality of the fuel used. As a rule, many atmospheric engines can work quite satisfactorily on AI92 gasoline.
• More fast warm-up in winter time.

Naturally, like any technical unit, the naturally aspirated engine has its drawbacks (compared to turbocharged counterparts):

• Less (by 30÷50%) power with the same engine size.
• Great weight and dimensions.
• Lower environmental friendliness.
• Less dynamic performance.

Advantages and disadvantages of turbocharged engines

The advantages of turbocharged engines (compared to atmospheric counterparts) include:

• More high power(as a rule, by 30÷50%) with the same working volume.
• Maximum torque over a wide rev range, which has a very positive effect on the dynamics of the car.
• Less weight and dimensions with the same power. turbocharged engine much lighter and more compact than atmospheric. This allows the most rational arrangement power unit and reduce total weight vehicle, which in turn contributes to fuel economy.
• Fast set of working revolutions due to the lower mass of rotating parts.
• High environmental friendliness, which is achieved through more complete combustion fuel in the engine cylinders.

The main disadvantages of turbocharged engines are:

• A smaller resource compared to "atmospheric", due to the large loads experienced by engine parts.
• Short turbine life. As a rule, after a run of 120,000 ÷ 150,000 km, it needs to be replaced (even if all the required operating rules are met).
• The need to use only high-quality high-octane fuel.
• Increased consumption oil, as the turbine bearings during operation are heated to very high temperatures.
• The need to use only special high-temperature synthetic oils.
• More frequent frequency oil change (at least every 10,000 km).
• Long warm-up in winter.

On a note! This shortcoming can be easily eliminated by installing a special preheater. However, this leads to additional material costs.

• High cost of repair and maintenance.

About fuel consumption

If you carefully read about the pros and cons of both engines (aspirated and turbocharged), then you were surprised that we did not say anything about fuel consumption. It is worth dwelling on this issue in more detail. Let's try to figure out which motor is more economical.

First, let's compare two engines with the same volume (for example, 1.4 liters). An atmospheric engine will consume an average of about 6 ÷ 7 liters per 100 kilometers, and a trumpeted one will need 8 ÷ 9 liters. However, at the same time, it develops power 1.5 times greater than atmospheric. Conclusion: with the same working volume, the “aspirated” is much more economical (after all, it not only “eats” less fuel, but also uses more cheap gasoline), however, it is significantly inferior to the turbocharged one in terms of power.

Now let's compare the fuel consumption of engines with the same power (for example, about 140÷150 hp). So many "horses" under the hood usually have a 2.0-liter naturally aspirated engine or a 1.4-liter turbocharged engine. In the urban cycle, the consumption of conventional engine will be about 12÷14 liters per 100 km, for a turbocharged one - all the same 8÷9 liters. Conclusion: even taking into account the lower cost of gasoline required for normal operation naturally aspirated engine, a turbocharged engine is much more economical.

What engine is the best car to choose

Both types of motors have their advantages and disadvantages. Therefore, it is impossible to say unequivocally which one is better. If you are a fan of aggressive driving, a quick start from a standstill, love the drive and are ready for significant maintenance costs, then the choice is clear - a car with a turbocharged engine. However, inclining to such a choice, we must remember that the motor of your vehicle(and especially the turbine) will “live” much less than the atmospheric counterpart. In addition, you must be sure that you can easily purchase fuel in your region. High Quality, as well as special synthetic oils.

If your driving style is calm, prudent and cautious, and you are also a practical and frugal person, then the excess power of a turbocharged engine is simply not tender for you. But the reliability, ease of maintenance and durability of the atmospheric motor will significantly save the cost of its daily operation.

To improve the efficiency of the engine can be used very efficient system, which is called a turbocharged engine. The use of a system of such a plan contributes not only to an increase in engine power, but also allows you to save fuel during its operation. At the same time, the toxicity of exhaust gases is significantly reduced.

What is turbocharging?

Turbocharging- a system of forced air injection into the engine cylinders, as a result of which more air enters the combustion chamber fuel-air mixture. An increase in the amount of the fuel-air mixture increases the average effective pressure in the cylinders, which leads to a significant increase in engine power with its design parameters unchanged. A turbocharged engine operates by using the energy of exhaust gases or by drive supercharger, which is rigidly connected to the engine and spends part of its power on its work.

How does a turbocharged engine work?

The principle is based on the power of energy possessed by exhaust gases. It drives the turbine wheel. It, in turn, contributes to the rotation of the compressor wheel. This is where the rotary shaft comes in handy. The task of the compressor wheel is to compress the air. It heats up, and after entering the intercooler, it is cooled, and it is fed into the cylinders.

1 – air filter; 2 - air supply sleeve low pressure; 3 - boost control valve; 4 - turbocharger; 5 - throttle assembly; 6 - air supply sleeve of cooled charge air; 7 – charge air cooling radiator (intercooler); 8 - air supply sleeve of hot charge air; 9 - air intake

How intensively the system will work depends on the nature of the work of the power unit itself. At the same time, it should be said that there is no rigid connection between the turbocharger and the engine crankshaft. The energy of the exhaust gases increases with the increase in the number of rotations of the engine. The stronger the motor works, the more intensively the energy potential increases. Consequently, the supply of compressed air also increases.

However, not everything here is so simple. There are a number of factors that are constraining the use of turbocharging. First of all, detonation can be attributed to such factors. Its occurrence is elementarily due to the fact that gasoline unit just dramatically increases its rotation. Another factor is the significant temperature parameters that the exhaust gases have. This provides significant heating of the turbocharger and the turbocharged engine as a whole.

What is a turbocharging system?

Structurally, the turbocharging device includes a turbocharger, an intercooler, a boost pressure control device and other components. However, the turbocharger plays the first violin in this design. With the help of it, an increase in pressure in the air intake system is ensured.

Air masses need to be cooled somehow. For this purpose, an intercooler is provided in the design. cooling compressed air coming from the compressor, it helps to increase its density. As a result, the pressure increases. Structurally, it is a radiator, and its type can be either liquid or air.

The system is controlled by a boost controller. He is nothing but bypass valve. Its main purpose is to limit the pressure of the exhaust gases. They don't all go to turbine wheel: a certain number of them go past him. In this case, the boost pressure becomes optimal. The valve is actuated by pneumatics or electricity. The sensor sends signals, resulting in valve actuation.

It is envisaged and safety valve. throttle valve may close abruptly, causing a sudden surge of air. The function of this valve is to protect against such actions.

In the case of aggregates, it is sufficient high power a system involving two parallel turbochargers is used.

If the turbines on the power unit are installed in series, then this provides an increase in productivity due to the operation of various turbochargers at different engine speeds. Developers do not stand still, but try to move forward. At the same time, instead of two, he installs three and even four sequential turbochargers.

Disadvantages of turbocharged engines

In general, all the disadvantages of turbocharging are as follows:

• Increased fuel consumption. At equal volumes, a turbocharged engine will consume more fuel by about 20%, but also produce Horse power 70% more. For some, this may be a plus, but for most car owners, this may not be necessary.
• Turbo engine resource. Since the engine becomes stronger in terms of power, and the characteristics of the general plan remain unchanged, wear of a very intensive nature of the main components occurs. The result of this is a decrease in the resource capabilities of the engine.
• Oil starvation. The disadvantages include the fact that reduced wear resistance piston group. The resource of the turbine itself is significantly reduced. This is facilitated by the fact that pressure from crankcase gases increases. If work in such conditions is observed for a long time, then " oil starvation". This, in turn, can lead to damage to the turbocharger. Problems from such important node may cause engine damage.
• Turbo lag and turbo pickup. There are such concepts as turbo lag and turbo pickup. The first occurs in situations where the gas pedal is pressed sharply. When the turbo lag is overcome, the turbo boost pressure increases sharply. We have already who are interested, you can read.
• Quality fuel and oil. Only the highest quality fuel will have to be refueled, otherwise the turbine can die very quickly. In addition, the use of turbines requires the presence of special grades of motor oils. At the same time, maintenance periods must be adhered to in accordance with the manufacturer's recommendations. At the same time, high requirements are also placed on the air filter, which will have to be changed 2 times more often than on a naturally aspirated engine.
• Expensive repairs and maintenance. The design and arrangement of the turbine is quite complex and only high-quality materials are used there, therefore their cost is not small. And if we add to this the high cost of the work itself, then the total cost of maintenance and repair comes out to be a round sum. For example, the cost of overhauling a turbine in good service can range from $1,000 to $1,500.

Despite all the downsides, turbocharged engines are the future of engine-based automotive internal combustion(we believe that the real future still belongs to cars with electric motors). At the moment, the most advanced turbocharging systems are considered TSI engines(Volkswagen) and TFSI (Audi). But not far behind Japanese manufacturers such as EJ20 (Subaru), 13B-REW (Mazda), RB26DETT (by Nissan), 2JZ-GTE (Toyota), 4G63 (Mitsubishi), etc.

Before buying a car, each of us faces a lot of dilemmas, it is necessary to choose between manufacturers, brands and models of cars, various configurations, and most importantly, between power units. A common question: "?", in popularity can only compete with the question: " What is better to choose, a turbine or aspirated?".

In addition, the turbo engine has a smaller engine life than naturally aspirated engine. The turbine wears out over time, especially if the owner does not have the skills to operate such engines. For example, after stopping the car, the turbo engine must be allowed to idle for a while so that the turbine cools down and only after that can the engine be turned off.

turbocharged engine repair cost it will cost much more than repairing an aspirated engine, in addition, there are not so many people who want to carry out this repair, some experts generally refuse to repair turbo engines. Those who take it sometimes perform repairs of poor quality, as a result, the engine runs intermittently or, over time, the turbo engine fails again.

As you can see, both engines have their "pros" and "cons", in order to understand which engine is better - turbocharged or naturally aspirated, you need to understand the priority aspects of a particular unit. Before you buy a car, you just need to weigh all the above pros and cons and accept final decision I hope it will be correct!?

I wish you good luck and see you again

What is the resource of a turbocharged engine this or that car is a question, the answer to which is often sought by drivers who want to buy a car on secondary market. After all, no one wants to lay out a substantial amount after the purchase for a major overhaul of the engine.

Life time turbocharged diesel and gasoline engines is large enough, but less than atmospheric. And the turbine, as practice shows, fails before the motor, while requiring the most careful care. In this article, we will consider what kind of resource turbo engines have modern cars and how to maximize it.

Diagnostics: a real opportunity to increase the resource of the turbine

Do you want to know the resource of the turbo engine of your car? We will diagnose the turbine and tell you in detail about the current state of affairs. If necessary, we will carry out competent maintenance of the turbocharger in full accordance with the manufacturer's recommendations.

turbocharged engine- a power unit that is equipped with a turbine, its main task is to pump air mass into the engine cylinders. Unlike atmospheric, which independently pumps air. Large quantity leads to better combustion of fuel, which increases power. Thus, due to more high efficiency, a turbocharged engine, compared to an atmospheric one of the same volume, will be much more economical.

On this moment turbochargers are found in almost all modern cars, ranging from small-capacity gasoline engines to multi-liter V12s.

Advantages:

1. High power compared to atmospheric. Even with a smaller engine volume, higher power is achieved due to the air being forced by the turbine.
2. Fuel consumption is less than atmospheric. If you compare by horsepower, and not by the volume of the power unit.
3. Turbocharged engines are more compact.
4. There are 2 and 3 options. cylinder engines, which in terms of power will not be weaker than atmospheric with 4 cylinders.

Flaws:

1. If you look at fuel consumption in relation to volume, then the turbo engine will “eat” more. For example, a 1.4 liter turbocharged gasoline engine will consume more gasoline than a 1.4 liter naturally aspirated engine. But at the same time it will be more powerful.
2. It is demanding on fuel quality, which is why a reduction in the resource of a turbocharged engine is often observed.
3. Turbo engine resource also depends on the quality engine oil. Pour mineral or semi-synthetics will not work, only synthetics.
4. As practice shows, the resource of the turbine less engine, and averages 120-150 thousand km. And the replacement is not cheap.
5. In winter, a car with a turbo engine requires mandatory warming up.
6. The need for turbine cooling. For this reason, it is not recommended to immediately turn off the engine after a trip, you need to let it work for Idling.
7. Change oil and filters more often than atmospheric.

The resource of the turbine is not much less engine life, and then only with proper and permanent care. The resource of a turbocharged engine is reduced due to ignoring the recommendations of the automaker for the care and maintenance of the turbocharger, or due to a malfunction of the power unit.

• Poor quality engine oil;
• Untimely replacement of oil and filters;
• Increased load on a cold engine;
• Oil starvation.

This four main reasons, due to which the resource of a turbocharged engine is reduced several times.

It must be understood that turbocharged engine, especially if it is small in volume, regularly works at the limit of its capabilities. Indeed, with a smaller volume, a turbo engine has the same power as an atmospheric one with a large volume. Due to the fact that it takes on heavy loads, and its wear is accelerated.

Many car manufacturers assure that the resource of a turbocharged engine is approximately 150-200 thousand km. After this run, you need to regularly check the compression, and if necessary, repair the engine.

However, this is less than 300 thousand km, which the aspirated engine passes without problems. And if all the rules and recommendations of operation are not observed, the resource of a turbo engine may not reach 100 thousand km.

Such a resource is due to the fact that the atmospheric engine has more simple design and not so picky about the quality of engine oil and fuel, which can not be said about the turbo engine. In addition, even in the event of a breakdown due to low-quality fuel, atmospheric restoration will cost significantly less than a similar engine with a turbine.

If the power unit is designed correctly, then the presence of turbocharging does not particularly affect the resource of a turbocharged engine. The car owner only needs to know the features of the operation of the turbo engine and remember a few important rules.

Instead of the prescribed engine oil change interval of 10 thousand km, change at 7.5 thousand km. Even with this mileage, the air filter will be heavily contaminated. And a dirty filter only increases the air intake resistance, resulting in a significantly reduced turbocharger performance.

Secondly, you should not save on the quality of engine oil. Pour into the motor what the manufacturer recommends in accordance with the tolerances.

Remember, the miser pays twice. And saving here is unacceptable, otherwise you risk reducing the resource of a turbocharged engine.

Third, do not overload the motor unnecessarily. Calm and moderate driving is a guarantee of durability not only of the motor, but of the car as a whole.

Fourth, after stopping the car, especially after a long trip, do not turn off the turbocharged engine. He needs to be allowed to run for 1-2 minutes at idle so that the turbine cools down. Because if you turn off the engine immediately, then the pressure of the engine oil will disappear momentarily, and the rapidly spinning rotor will be without lubrication for a while. Thus, the service life of the turbine is greatly reduced.

An article about atmospheric and turbocharged engines - their main characteristics, features of work, advantages and disadvantages. At the end of the article - a video about both types of engines.

The content of the article:

Over the past decade, automakers have been increasingly converting their cars to turbocharged gasoline engines. At first glance, the advantages of turbo engines over more traditional atmospheric engines internal combustion are obvious. First of all, manufacturers point to fuel economy and more a high degree environmental friendliness. But is it really so clear?

In order to decide which type of engine is preferable for you, let's look at the advantages and disadvantages of both types.

Main characteristics of both types

The atmospheric engine is a classic ICE (internal combustion engine). Air entering the system through filters is mixed with fuel (gasoline, diesel fuel). The resulting mixture ignites in the combustion chamber and propels the pistons. The engine operates at normal atmospheric pressure.

The main difference between a turbocharged engine and an atmospheric one is that the turbine that gave the name to this type is installed inside it. She is responsible for the forced injection of air into the cylinders. As a result, the air in the combustion chamber is high blood pressure which ensures better combustion air-fuel mixture and, consequently, a higher capacity of the unit.

The atmospheric engine has been used in the automotive industry for many decades. In fact, the very first cars were already equipped with such a motor.

"Atmospheric" is distinguished by the following advantages:

• good resource;
• reliability in operation;
• durability;
• ease of use;
• the relative ease of carrying out preventive and repair work;
• unpretentiousness in relation to fuel quality.

The reliability of the naturally aspirated engine is eloquently evidenced by the numbers. High-quality motors allow the car to travel up to 500 thousand kilometers. In the history of the development of the automotive industry, there are cases when the engine was moved from an outdated car to a new one, and it continued to work properly for many more years.

High-quality gasoline, of course, lengthens the life of the engine. But at the same time, the “aspirated” is quite able to function on fuel of lower quality.

The list of brands of oil that can be used in a particular unit is much wider than the strictly limited list of brands and names for a piped engine.

The design of the "atmospheric" is such that not only a professional, but also a competent motorist can handle its repair or maintenance. The unit can be disassembled to the last detail and reassembled - the design allows you to do this at no extra cost. It is not uncommon for the repair of the unit to use "non-native" parts and components manufactured by other manufacturers. Accordingly, the cost of repairing such an engine is cheaper.

Of the minuses of this engine, the most significant are:

1. Lower, in comparison with the turbocharged engine, power.
2. More high flow fuel.

If we compare naturally aspirated and turbocharged engines of the same size, the naturally aspirated engine obviously loses to its competitor in terms of power.

If we compare two engines of the same power, for example, 140 hp, then it turns out that a 2-liter naturally aspirated engine will require 12 liters of gasoline (per 100 km), and a “turbine” with an even smaller volume (1.4 liters) will cost 8 liters. The difference is obvious.

However, this list of "cons" is exhausted. Atmospheric internal combustion engines are reliable, simple and durable, but they are not designed for heavy loads and high revs.

It is possible to equip a turbine with both gasoline and diesel engine. In the automotive industry, a turbocharged engine was first used in 1938 by truck manufacturers.

For cars"times of turbines" began in the 50s of the last century. At first, such an engine did not differ high reliability, therefore, did not cause much interest among motorists. But the design was constantly refined and improved, in the end, after all, it won an army of fans.

By its design, a turbocharged engine is a classic atmospheric internal combustion engine, supplemented by an air-blowing turbine. The turbine is responsible for the forced pumping of air into the cylinders. As a result, the pressure of the air-combustible mixture in the combustion chamber is higher than atmospheric pressure, the fuel burns more efficiently than in a classic atmospheric internal combustion engine and, on the same volume of fuel, gives significantly more power and torque.

The main advantages of a turbocharged engine are:

• high power;
• more economical, compared to an atmospheric engine, fuel consumption with the same amount of horsepower;
• smaller overall dimensions;
• less weight;
• less noise during operation;

The turbine engine is compact. On three or even two cylinders, it gives power comparable to the power of a four-cylinder "aspirated".

Compactness is an obvious advantage, such an engine allows various options location in the car.

With more high pressure fuel burns more productively - accordingly, less combustion waste enters the atmosphere. For this reason, a turbocharged engine is considered more environmentally friendly.

Unfortunately, the pros end there and the cons begin:

1. Sensitivity to the quality of the fuel used.
2. Sensitivity to oil quality.
3. Need more frequent replacement oils.
4. Small resource of the turbine.
5. The need for longer heating in winter.
6. Higher cost of repairs compared to a naturally aspirated engine.

If we analyze fuel consumption not from the standpoint of horsepower, but from the standpoint of volume, it turns out that a turbocharged engine requires more fuel than a naturally aspirated engine of the same volume. True, and power, as already mentioned, the "turbine" will give out more.

The quality of gasoline for a "turbine engine" is critical - for example, 92nd gasoline is unacceptable for it. If you still transfer a car equipped with a turbo engine to it, things will very quickly come to repair.

With oil - the same situation: each manufacturer of a turbocharged engine in the accompanying documentation strictly indicates the list of brands synthetic oil that can be used in the aggregate. Compared to semi-synthetic and mineral oil the cost of "pure synthetics" is 35 - 40% higher.

Oil is added not only to the engine itself, but also to the turbocharger unit. At the same time, the "turbine" requires complete replacement oil every 10,000 kilometers. Compare these figures with a naturally aspirated engine, where the oil is changed every 20,000 kilometers, and the oil itself is cheaper ... the conclusions are obvious.

Finally, the service life of the turbine is 120,000 kilometers(and this is provided that the engine is constantly properly cared for, and only the brands specified by the manufacturer are used for fuel and oil). After that, a replacement is necessary, and it will cost very, very expensive.

At all repair turbocharged unit- costly pleasure: components are made from expensive materials, spare parts, respectively, "fly a pretty penny."

We should not forget about such an unpleasant phenomenon during the operation of a turbocharged engine as "turbojams". The essence of the phenomenon is that low revs the engine "does not pull" because its volume is small. This unfortunate drawback manifests itself at the start of the engine, when a sufficient amount of air has not yet been pumped into the chamber, and it is not possible to quickly reach the required power. The result of "turbo lag" is the slow acceleration of the car from a standstill. For megacities with their heavy traffic and difficult traffic conditions, such a disadvantage can become critical.

Designers are trying to deal with "turbo lags" by offering motorists engines with two turbines, where the second one can even be equipped with an electric drive to operate at low speeds. Such a solution reduces the likelihood of "turbos", but complicates the engine structurally and further increases its cost. At the same time, the reliability of the unit equipped with another turbine decreases.

The main thing to remember is that a turbocharged engine is more powerful, but requires more attention and care. In the maintenance of the "turbine" you only need quality fuel And expensive oil which needs to be changed more often. At the same time, the turbine itself has a small operational resource.

"Aspirated" is not as powerful as its turbocharged competitor. But at the same time, it is economical in operation, unpretentious regarding the brands of gasoline and oil. When repairing an atmospheric engine, it is possible to use “non-native” parts even from another manufacturer (in the case of a “turbine engine”, this is completely unacceptable).

So, there are enough advantages and disadvantages for both types of engines. Which option to choose?

Most likely, the long dispute between fans of both types of engines is far from over. The work of designers and engineers constantly adds arguments to one side of the scale, then the other.

Choose what is called, according to your material capabilities and preferences. "Atmospheric" is suitable for motorists with a smaller budget. The turbocharged version is the choice of those for whom dynamics and power are fundamentally important, and the cost of purchase and further operation can, as they say, be neglected.
