It is useful for owners of budget vehicles to find out the features of the power units installed on Kia Ria cars. The forthcoming study focuses on the merits and demerits of these engines, recommendations for proper maintenance and maintenance. This publication will help you determine the correct fuel and oil.
Not every driver can afford a business class car from leading European manufacturers. Most are content with little, choosing domestic cars.
There is one more budget option provided to the Russian market by Korean automotive suppliers. This article will tell you what the Kia Rio engine is in reality, and what measures will help the owner preserve the original characteristics of the unit for a long time.
Characteristics of the power plant Kia Rio
Korean manufacturers have taken care of the convenience of Russian motorists. Their creation is great for domestic roads. This is facilitated by the following characteristics of the power unit:
- possibility of refueling with AI-92 gasoline. For most owners of a budget vehicle, the issue of saving is in the first place, so the use of cheap fuel is important;
- in difficult conditions of Russian roads, a special anti-corrosion compound is very useful, which protects the bottom of the body from the effects of domestic dirt;
- the harsh climate is not a hindrance to starting the engine. The developers have provided for the ability to start the engine at temperatures down to -35 0 C. Therefore, the car has proven itself well even in the northern regions;
- domestic utilities are struggling with icing winter roads, sprinkling them abundantly with salt. Korean manufacturers secured the radiator by protecting it with a special composition that protects it from such troubles.
It should be noted that the Kia Rio provides for the installation of power units of two types, differing in volume and power. Each of them requires separate consideration.
Features of the 1.4-liter Kia Rio engine
To begin with, we note that this power unit is basic. Its feature is considered to be the ability to develop engine power at 6300 rpm, which is considered the equivalent of 107 horsepower. Taking into account the use of the AI-92, this is a very good indicator. The mechanical transmission allows the car to reach a speed of 100 km / h in just 11.5 seconds.
On an open track, such an engine consumes only 4.9 liters of fuel. Driving on city streets increases the absorption of gasoline up to 7.6 liters. Combined movement is characterized by a fuel consumption of 5.9 liters.
In another measuring system, 1.4 l corresponds to a volume of 1396 cm 3. The engine has four active cylinders. Each of them has 4 valves. The working stroke of the piston is defined as 75 mm inside a cylinder with a diameter of 77 mm.
Finally, we note that fully using the resource of the Kia Rio engine, the driver is able to reach speeds of up to 190 km / h. Such indicators are very acceptable for domestic motorists who prefer fast driving with minimal fuel costs.
Features of the 1.6-liter engine
The relatively small volume, however, allows the power unit to develop engine power comparable to the efforts of 123 frisky horses. This allows the driver to feel unshakable confidence in the reliability of the vehicle.
Personally, I pour only Ai-95 into the gas tank of such an engine. In this case, saving money by refueling with cheaper fuel is very unreasonable, since this can negatively affect the performance of the engine for the Kia Rio.
Another distinctive feature of the engine that equips the Kia Rio is the timing drive, represented by a chain mechanism. This greatly simplifies the replacement process and increases the durability of the device. Although the timing chain contributes to an increase in some driving harshness and noise in the cabin, these disadvantages are fully compensated for by an increase in the reliability and endurance of the power unit.
When driving around the city, the 1.6-liter engine consumes approximately 8 liters of fuel. If you intend to travel on an open road, fuel should be poured into the tank at the rate of 5 liters. It is somewhat more difficult to determine how much gasoline is needed when driving on a combined type of terrain. Experienced mixed-cycle drivers store 6.6 liters.
The engine's dynamic performance is similar to that of the previous model. Only the piston stroke and cylinder diameter differ. For a 1.6 liter power plant, they are 85.4 and 87 mm, respectively.
1.6 L engine defects
Possessing a sufficient number of positive characteristics, the motor model under consideration also has quite significant flaws. They deserve special mention:
- the limited space of the engine compartment with a sufficiently large engine size makes access to some components very problematic. Therefore, certain parts can be repaired only after additional dismantling of the power plant;
- since the temperature of the engine in the operating mode is quite high, problems can arise from the material of manufacture of the cylinder head. As you know, aluminum does not tolerate thermal overvoltage well. However, this flaw is compensated for by the output of the technological alloy;
- ignition and gas distribution systems must be replaced only as a set. This simplifies the overhaul of the engine, reducing labor costs, but makes it impossible to partially replace parts of these mechanisms;
- perhaps the most significant drawback of the considered power units is considered to be low maintainability. Even professionals of specialized services, with great reluctance, undertake major repairs after damage to the main components.
The listed disadvantages in no way detract from the indisputable advantages of this motor. They are also worth considering in more detail.
Advantages of the 1.6 l power unit
Most modern car enthusiasts prefer to purchase cars with just such an engine. When choosing, the following positive aspects characterizing the motor are taken into account:
- savings due to reduced fuel consumption. Moderate driving on a combined cycle route requires only 6 liters of fuel. Personally, I have always poured gasoline from this calculation;
- attractive is the extreme reliability of the main functional units, which ensures the trouble-free operation of the Kio Rio sedan engine for more than 200 thousand kilometers;
- high dynamics, characterized by the ability to accelerate to 100 km / h in just 10.3 seconds;
- the optimal distribution of characteristics between the engine and the transmission creates an excellent elasticity of the power plant. This instills confidence in the driver in the most difficult driving situations.
Despite some difficulties caused by the impossibility of partial replacement of certain elements of the gas distribution mechanism and the ignition system, for professional mechanics of specialized service workshops, repairing a Kia Rio engine is quite common. The cost of such services is also considered quite acceptable.
The exclusivity of the resource of the power unit is confirmed by the owners of cars who have covered more than 300 thousand km over a five-year period. The remarkable fact is that the sedan did not show any tangible engine problems.
The manufacturer provides for the need for a technical inspection after every 10 thousand km. Even middle-income car owners can afford to use the services of specialized workshops. The affordable maintenance cost is due to the simplicity of the power unit design.
There are several secrets that can increase the resource of the motor:
- the service life of the car largely depends on what kind of oil is poured into the Kia Rio engine. It is recommended to choose brands of trusted manufacturers, certainly taking into account the seasonality of the oil product. It is also necessary to regularly update the engine oil for the Kia Rio, be sure to replace the oil filter. Manufacturers set the maximum mileage on the same lubricant, determined by 15,000 km. However, experienced drivers try to change the oil product every 7000 km;
- gasoline should be filled exclusively at specialized gas stations. This will help eliminate the use of low-quality fuel. Cheap counterfeit fuel can quickly disable a completely serviceable power unit;
- the last tip concerns driving style. A calm measured ride will keep the car much longer than recklessness.
Kia Rio cars of the third generation are equipped with the G4FA engine from the new Gamma series (since 2010, these power units have replaced the Alpha series motors), volume of 1394 cm cube, which meets the environmental standards Euro-4. It is produced at the Chinese plant "Beijing Hyundai Motor Co".
Besides Kia Rio-3, this engine is also installed on Kia Ceed, Hyundai "Solaris" (or "Accent"), Hyundai i20, Hyundai i30.
G4FA engine specifications
- The G4FA engine has 4 cylinders, each with 4 valves.
- The maximum power is reached at 6300 rpm and is 107-109 horsepower.
- The engine uses a timing chain with tensioners (during the guaranteed motor life of 180 thousand km, the chain does not require maintenance).
- The manufacturer recommends using fuel - AI-92, and engine oil with viscosity parameters - 5W-30 (see "").
- The engine maintenance interval is 15 thousand km (see "").
7 main disadvantages and malfunctions of the G4FA engine
- Engine knocking (most common problem).
If it passes after the engine warms up, then, in 90% of cases, it is caused by the timing chain (you should not worry, this is the norm).
If it does not disappear at engine operating temperature, then it is most likely due to unregulated valves. - Chirping, clatter, clicks, etc. soundsthat are audible when the engine is running.
Do not be afraid of these sounds - this is how fuel injectors work. - The occurrence of uneven engine operation ("Floating" revolutions).
Solved by cleaning the throttle valve. When this does not help, then you should try a fresh "firmware". - Vibrations that appear at idle.
May occur with a dirty throttle valve or spark plugs (see "How to replace the Kia Rio-3 spark plugs"). If vibrations persist after flushing the throttle valve or replacing the spark plugs, pay attention to the engine mounts. - Vibrations when rotating the crankshaft at a frequency of about 3000 rpm.
According to official dealers - the cause of vibrations is the occurrence of resonance between the units and components of the car due to design features. In order for the engine to come out of resonance, it is recommended to sharply depress the accelerator pedal and release it. - Whistling under the hood.
The reason is the weak tension of the alternator belt. After replacing the tensioner pulley, the whistle disappears. - The appearance of oil drips from under the valve cover.
Everything is treated with a simple replacement of the gasket.
It should also be noted that due to the lack of hydraulic lifters in the engine, every 95 thousand km, replacement of pushers and adjustment of valve clearances are required. Despite the high cost of the procedure, this should be done without fail, because subsequently, this can lead to significant problems in the operation of the engine: "tripping", noise, burnouts, etc.
The most depressing thing is that the listed malfunctions can appear at the very beginning of the car's operation. therefore buy a used Kia Rio-3 with such an engine very carefully, and if you take a car with more than 100 thousand km of mileage, you can buy "firewood".
Attention! The cylinder head of the G4FA engine cannot be repaired. bore for repair size is not provided by the manufacturer.
How? Haven't you read it yet? Well, it's in vain ...
We will be grateful for the pressed social buttons!
In the modern world of motors, there are a fairly large number of car tuning ateliers.
But not all of them manage to become truly popular and gain cult status.
Brabus. This company from Germany has objectively been the best for a long time, having no worthy competitors. At the moment, it is a huge holding company, which includes a company founded together with Daimler AG. In addition, it also houses a subsidiary company Startech, which specializes in tuning work for Jaguar and Land Rover, a restoration workshop, as well as another department whose task is to carry out finishing work and develop the design of business jets and yachts.
Its name was made up of the names of its two founders - Klaus Brackman and Bodo Buschman, whose hobby was carrying out modifications to Mercedes-Benz.
In the 70s, the main emphasis was placed on a bright appearance, relegating power to the background. The company began to create powerful engines only in the 90s, which resulted in the creation of the famous V12 with a volume of 6.9 liters, the power of which was 508 hp. It was intended for installation on the Mercedes-Benz E-class.
Throughout the history of its work, the company has repeatedly been awarded the title of the best car tuning studio.
Alpina... As a student at a university in Germany, Burkard Bovensiepen could not even think that carrying out an independent repair of his FIAT-500 after a breakdown would be so successful. After that, he decided to test his strength already on the BMW-500, which, after carrying out improvements, acquired not only increased power, but also the first owner.
In 1964, his activities attracted the interest of representatives of BMW, who sent two-chamber carburetors created by him for testing. Overjoyed by this approval, Bovensiepen opens his car tuning studio.
The dynamic qualities of the updated cars were demonstrated on the race tracks. For the Spa Francorchamps 24-hour race, a special BMW 3.0 modification was carried out with specially developed 20-spoke rims, which eventually became a distinctive feature of the model.
One of the automaker's best accomplishments was the fastest sedan Alpina B10 Bi-Turbo, created in 1989. By the anniversary of the company in 1999, the most powerful diesel unit D10 Bi-turbo, whose engine power was 245 hp, rolled off the assembly line, which became the most powerful sedan in the world with a diesel power plant.
Hennessey Performance... The brainchild of John Hennessy, known as a race car driver, was created in 1991 in the state of Texas and gained fame as one of the world's most productive tuning studios.
Together with a group of mechanics, as a trial, he tried to improve the Japanese-made cars that did not go into mass production. Success came to his company after working on the Dodge Viper, which, after the update, became more powerful, reached a maximum speed of 217 km / h and opened up access to participation in any kind of competition.
The Korean car Kia Rio has been produced for four generations. Over an 18-year period of time, the model managed to fall in love with a huge number of drivers around the world. High popularity is associated not only with low cost, pleasant interior, and external appearance, but also with the reliability of engines, low fuel consumption and good dynamic characteristics.
List of engines
ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe me? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!
Like any other car that has been produced for more than one generation, the Kia Rio had its weak points. Let's analyze all the strengths and weaknesses of various engines and find out the reason for some of them compared to others.
| Brand | Generation | Maximum power, h.p. (kW) at rpm | Maximum torque, N * m (kg * m) at rpm. | A type | Fuel consumption, combined cycle, l |

Kia Rio and X-line engine range
1st generation
The car appeared on European roads in 2000 and was presented as a sedan, station wagon and hatchback. Under the hood of the Rio, there were 2 small-displacement gasoline engines with a volume of 1.3 and 1.5 liters, with a capacity of 75 and 97 horsepower, respectively. In the period from 2003 to 2005, updated models were produced, but the same power units remained in them.
2nd generation
In the fourth quarter of 2005, the second generation entered the market. Thanks to the efforts of the designer Perer Schreier, the car has significantly changed in appearance. Manufacturers could not continue to install low-power engines as this would not fit the car's concept. Therefore, the line of motors has been updated.
Now the buyer could purchase not only a gasoline, but also a diesel car. The working volume of the cylinders has not changed much, but the power of the car has become much higher. This was due to the use of 1.4 L G4EE, 1.6 L G4ED, 1.5 L CRDi D4FA engines. The power of these power units was 97, 112 and 104 hp. 
The car has become much more dynamic and maneuverable. Coupled with a four-speed automatic transmission and five-speed mechanics, the power units showed good performance. The torque reached 125, 146 and 235 N * and at 4700, 4500 and 1900 rpm.
3rd generation
The huge success of the car contributed to the third generation of cars. It happened in April 2011. Then, two models of the Korean manufacturer Kia Rio and Kia X-line appeared on the market at once with the same 1.4 and 1.6 liter single-row 16-valve G4FA and G4FC gasoline engines, the power of which was 107 and 123 horsepower, respectively.
4th generation
The 4th generation car of 2017 uses the G4FC engine with 100 and 123 hp. This is the same 16-valve in-line engine used in the 3rd generation. The choice of the manufacturer in favor of this engine was obvious due to its reliability and high technical performance.
What engines are most widespread.
In various generations of the Kia Rio and Kia x-line, power units such as A3E, A5D, G4EE, G4FA, G4FC, G4LC were used. The most widespread is the G4FC power unit, which is installed on the Kia Rio and Kia X-line to this day.
Engines of the 1st generation A3E, A5D with volumes of 1.3 and 1.5 liters
Drivers of Kia Rio 1st generation cars characterize the car engine on the positive side. It has good dynamics, which made it possible to keep up with the flow at one time, and sometimes even give odds to other cars of its class.
The real thrust begins when the RPM hits 2000 rpm. Low vehicle weight has a negative effect on driving dynamics. It shows the best acceleration performance when there are more than 2 people in the car. Fuel consumption is 6 liters on the highway and 8 liters in the city. It must be said that this is not so small for a 1.4 liter engine. 
Weaknesses of 1st generation motors:
- Sensitivity to fuel quality and oil used. If you are late in changing the oil, then seizures will form on the pistons and cylinders that are difficult to eliminate.
- Frequent occurrence of piston valves and unreliability of valves, the malfunction of which can be indicated by uneven compression in the cylinders.
- Scoring on the crankshaft due to the use of contaminated or poor-quality oil.
Engines of the 2nd generation G4EE, G4ED, CRDi D4FA volume of 1.4 and 1.6 liters
G4EE
The G4EE gasoline engine is quite reliable. It was produced from 2005 to 2011 and installed on cars of various manufacturers, including the Korean one. It has a low fuel consumption of 6.2 liters in mixed mode.
The most common malfunctions of the G4EE engine:
- Breakdown of the ignition system, which lead to jerks while driving.
- Rapid clogging of the fuel filter, leading to the same consequences.
- Oil leaks from under the valve cover.
- Increased oil consumption after 100 thousand km, associated with gradual wear of the cylinder-piston group due to the use of low-quality oil or untimely oil change.
- Severe vibrations associated with a defective engine mount.
G4ED
This is the first diesel power unit that was installed on a car of the RIO line. A feature of the motor is the use of liners as cylinders. This somewhat reduces the engine resource. The enforcer has hydraulic compensators that automatically adjust the clearances.
Weak points of the engine:
- Rapid wear of the elements of the cylinder-piston group after 100 thousand kilometers in case of untimely oil change.
- Low prevalence, due to which finding spare parts is not always easy and cheap.
In general, the engine is quite reliable, but the car should be bought only by those drivers who constantly monitor it and make timely replacement of technical fluids.
CRDi D4FA
This motor is equipped with a Common Rail system. Thanks to this, it is able to accelerate the car faster without increasing fuel consumption. The power of the power unit reaches 110 hp. Just like the previous engine model, it is equipped with hydraulic lifters.
Main advantages:
- Increased resource.
- Low fuel and oil consumption.
- Low noise level.
- Easy to start in cold weather.
The engine also has characteristic disadvantages:
- There are cases of early stretching of the timing belt.
- Low prevalence, so spare parts are not easy to find.
3rd generation engines
Despite the good characteristics of the engines in the 2nd generation, the manufacturer decided to update the line and began to produce the Kio Rio with G4FA and G4FC engines.
These engines differ in displacement and, as a result, in technical characteristics.
But what are the differences between them and why was G4FC used in the fourth generation?
G4FA
The manufacturer of these power plants was the Chinese company Beijing Hyundai Motor Co. They are distinguished by low consumption, have a power of 109 horsepower. As practice has shown, such a motor has a resource of more than 200 thousand kilometers, which is not bad at all in our time. With timely maintenance and the use of high-quality components, you can ride a car twice as much. 
The main distinguishing feature of the engine is the use of a timing chain with a tensioner, thanks to which it is not necessary to replace the element throughout its entire use.
Malfunctions that the owners of Rio and X-line encounter during operation:
- Increased noise or knocking due to poorly adjusted valves. Can be fixed at the service center. Such a pseudo malfunction appeared due to the lack of hydraulic lifters.
- Leaking valve cover due to poor quality gasket. Can be replaced at a service center or by yourself.
- Floating revolutions. If this problem occurs, you should clean the throttle valve or change the firmware.
- Vibrations at medium speed. But they arise due to the characteristics of the engine and do not affect the performance of the unit.
- Tensioner pulley whistle that disappears after replacement.
Despite such a large number of faults, most of them are quickly eliminated and are of minor importance.
G4FC
I must say that the G4FC and G4FA motors belong to the same Gamma series and do not have many distinctive features.
Unlike the G4FA, the G4FC engine has an increased piston stroke and higher power, which appeared due to the larger displacement of the cylinders.
Disadvantages of engines repeat each other. If we compare the G4FA and G4FC motor, then many will prefer the second motor, as well as the manufacturer. Indeed, at almost the same flow rate, the second unit has more power, which means it is able to develop its initial speed faster and has better dynamic characteristics. The power of the G4FC reaches 123-130 hp.
4th generation engine
It was not a great surprise to anyone that the manufacturer preferred to install the old G4FC engine in the new generation car. The use of direct injection GDI gave the groundwork to manufacturers for a dozen years, since fuel consumption has significantly decreased compared to older engines, and power has increased.
At the same time, one can also note the reduction in emissions and the actual reliability of the power unit. The manufacturer gives a guarantee for engine operation over 180 thousand kilometers, but practice has shown that this figure is far from finite.
The unit during operation does not cause great problems to its owner. You can fill it with not the best 92 gasoline, but still it will give all its strength on the road, providing the best dynamic performance.
In service centers, they note the convenient location of all the main elements that are most often repaired: candles, an air filter, an intake and exhaust manifold, engine cushions.
Due to the short start-up, the power unit has less pumping losses during suction. There is also a lack of a lot of plastic, as in other modern powertrains. The most important thing is to carry out maintenance in a timely manner, do not forget to change the oil after 10 thousand km. Using high quality synthetic oil and prefer 95 gasoline.
When creating the new 2018 Kia Rio X-Line, the company decided to install the same engines on the hatchback that will be on the sedan.
With this, marketers decided to kill several birds with one stone - and the engine compartment will not have to be recycled, and buyers will receive familiar and used engines, and there will be no problems with service, and the price of the car will fit into a reasonable framework.
It must be admitted that they calculated everything very accurately.
Engines KIA Rio X-Line
The range of power units is represented by two gasoline engines:
- 1.4 L G4LC Kappa Series - 100 HP from.
- 1.6 L G4FG of the Gamma family - 123 HP from.
There will be no diesel versions of the model, as is the case with the sedan. Equipping the car with turbocharged engines is also not expected, although some, having seen the sparkling chrome forked exhaust, hoped so.
As for the units themselves, they have both common features and features.
Both Kia Rio X-Line engines have an in-line arrangement of 4 cylinders with 16 valves. Distributed fuel injection. They also have a double complex of variable valve timing - both at the inlet and at the outlet. In addition, the motors have modified torque indicators, which made it possible to achieve a significant increase in thrust of 6% (for 1.4 liters) and 7% (for 1.6 liters) in the operating range. All this guarantees the smoothest operation and quick response to pedal presses.
Also, the hatchback engines have the latest ShPG coating - this significantly reduces friction losses and reduces fuel consumption. Temperature modes of operation are optimized, and the noise background is also reduced.
For both 1.4-liter and 1.6-liter engines, there are two transmissions - MKPP6 and AKPP6.
Both motors will be paired with a 6-band automatic
1.4 L G4LC Kappa series
This Kia Rio X-Line 2018 engine is assembled in Korea and supplied to Russia. Structurally, it is distinguished by the presence of 2 phase shifters, a variable length of the pipeline (inlet), as well as a chain in the timing drive.
In comparison with the previous G4FA engine of a similar displacement, its power has decreased from 107 hp. from. up to 100 liters. from. The torque has also slightly decreased - from 135 to 132 Nm, but now it is achieved much earlier - by 4000 rpm, versus 5000 rpm.

1.6 L G4FG Gamma family
This is an upgraded powertrain based on the G4FC series. Unlike its predecessor, it has different pistons, camshafts, another intake phase shifter and a variable intake tract. As a result of the modernization, the power remained at the same level of 123 hp. from. However, the maximum torque is now only 150.7 Nm at 4850 rpm, versus 155 Nm at 4200 rpm. from the previous motor.

As you can see, the engines of the Kia Rio X-Line 2018 are quite modern and more than competitive, especially considering that they will be paired with gearboxes that are excellent for their level. Yes, some are afraid that over time, the timing chain will stretch and begin to rattle, however, unlike the belt, it does not break, which significantly increases the reliability of the motors.
So far, only the question remains regarding the dynamics and fuel consumption. In any case, the mass of the hatchback will exceed that of the sedan, which will affect its appetite. In addition, driving with a full load, when there are 5 people in the cabin, and the load in the trunk brings the weight of the car to the maximum, it is quite possible that it will also affect the fuel consumption of the Kia Rio X-Line.
