Tara V4 Turbo is considered the new and flagship product of the Tara product series, which compared to other versions, we see many differences in the technical department.

Tara has a different position in Iran Khodro's product portfolio than many domestic sedans. From the beginning, this car entered the market with a focus on good cabin space, roomy trunk and acceptable features, but one of the issues that were raised compared to some competitors was the technical performance of the versions equipped with the TU5P engine. An engine that seems suitable for everyday use and economic driving, but in a relatively heavy sedan, it cannot always convey the feeling of an agile car to the driver when accelerating or overtaking on the road.

Now, by introducing Tara V4 Turbo, Iran Khodro follows a different path in the development of this sedan. In this version, the naturally aspirated TU5P engine has been replaced by the EFP turbocharged engine; A change that is not only limited to increasing the engine volume, but also significantly increases the output power and torque. The use of a six-speed automatic transmission along with this engine makes Tara Turbo a more powerful version of Iran Khodro's well-known sedan.

However, to know exactly how the Tara Turbo differs from the regular V4 versions, it's not enough to just look at the power and torque numbers. A look at the engine type, gearbox performance, powertrain and what parts remain unchanged gives a clearer picture of the nature of this technical update.

The regular Tara V4 uses a 1.6-liter TU5P four-cylinder engine with a displacement of 1,587 cc. This naturally aspirated engine produces about 113 horsepower and 144 Nm of torque and has an acceptable performance for daily use, city commuting and family trips. However, when driving with a full load or needing to accelerate quickly, its power limitation is more felt.

In Tara Turbo, the turbocharged EFP or EF7P engine has been replaced with a precise volume of about 1645 cc. This engine was previously used in products such as Rayra, and in the version used in Tara, it has the ability to produce 160 horsepower and 240 Nm of torque.

These numbers show the difference between the two versions. Tara Turbo gives the driver about 47 horsepower and 96 Nm more torque than the TU5P version. Increasing torque is particularly important; Because the only issue is not reaching high speed, but the ability of the car to increase speed in the conditions when the engine is under pressure.

In a naturally aspirated engine, the engine speed must usually be increased to achieve more power. But by compressing the intake air, a turbocharger allows more air to enter the cylinders, allowing the engine to produce more power in a relatively similar volume. Of course, actual performance depends on engine settings, boost pressure management, and technical package coordination.

The difference between the Tara V4 and the turbo version is probably more pronounced in acceleration and traction than anything else. The 113 hp TU5P engine is sufficient for normal movement, but when overtaking or going uphill, the driver may need to press harder on the gas pedal and increase the engine speed.

The EFP engine's 240 Nm torque can change the situation. If the engine and gearbox are properly matched, the car will react more powerfully when the speed increases, and the driver will have more capacity to maintain acceleration on steep roads. This difference is of practical importance for a family car that may travel with several passengers and cargo.

Acceleration from 0 to 100 tare turbo is announced in some published specifications as about 9 seconds; While the automatic version of TU5P needs more time to reach the same speed. Of course, the acceleration figures depend on the test conditions, vehicle weight, road condition and ambient temperature, and they should not be assumed to be the same in all conditions.

Another point is that the turbo engine does not necessarily have an instant response in all situations. The amount of turbocharger delay and how the gearbox reacts when the gas pedal is pressed suddenly is important in the driving experience. Therefore, in order to accurately evaluate Tara Turbo, in addition to the nominal power, the car's behavior at the start of movement, intermediate acceleration and overtaking should also be examined.

In the power transmission department, the Tara V4 Turbo still uses a six-speed automatic transmission and engine power is sent to the front wheels. Therefore, contrary to what might be expected from a new version, the introduction of the turbo engine does not mean a complete change of the power transmission architecture.

The importance of the gearbox in this version comes from the fact that it must be coordinated with the greater torque of the engine. Choosing the right gear, shifting speed and how the power is sent to the wheels can determine how much the power increase will be felt in real driving. If the gearbox reacts in time, the driver can more easily use the engine's capacity when overtaking or accelerating.

Gearbox performance is also important in city traffic. The smoothness of movement from a standstill, gear changes and response to quick changes of the gas pedal affect the comfort of daily use. Therefore, the quality of engine and gearbox coordination is one of the parts that should be considered in the Tara Turbo practical test.

Despite the significant increase in engine power, Tara V4 Turbo is not fundamentally different from normal versions in terms of the overall structure of the body and suspension system. MacPherson system is used in the front axle and semi-independent suspension with torsion bar is used in the rear axle. Therefore, installing a more powerful engine alone should not be expected to transform the car's cornering behavior or ride quality.

Increasing engine power increases the importance of car control; But to evaluate stability and handling, factors such as suspension settings, tires, brakes and stability control systems should also be considered. In the published information, there is no fundamental change in the suspension architecture of this version. Consequently, the main superiority of the Tara Turbo is to be found in the powertrain, not in a complete transformation of the chassis or suspension.

This is not necessarily a weakness; Because the purpose of developing the turbo version was to increase the power of the car. However, buyers expecting simultaneous improvements in acceleration, stability and ride quality should factor this difference into their decision making.

One of the important questions about the Tara Turbo is its fuel consumption and maintenance cost compared to the TU5P version. The turbocharged engine requires more careful maintenance due to its more complex structure and different working pressure. Using the right oil, meeting the service schedule, and paying attention to fuel quality are among the things that can affect the durability of the engine.

Of course, it cannot be said that the turbo engine has more consumption in all conditions; Because the actual consumption depends on the driving style, the amount of turbo boost and road conditions. Slow driving can keep consumption under control, but frequent use of higher power will usually require more fuel.

For the Iranian market, access to parts and the familiarity of repairmen with the EFP engine are also important. Since this engine has been used in other Iran Khodro products, the expansion of technical experience and parts supply network can be a potential advantage; However, actual maintenance costs and long-term durability need to be determined in practical use.

Tara V4 Turbo can be seen as a version developed to meet the needs of buyers who expect more from Tara in terms of power and acceleration. This car with 160 hp engine and 240 Nm torque, compared to the TU5P version, offers more capacity for dynamic driving and can be a more attractive option for road trips and overtaking.

However, its purchase value is not only dependent on technical specifications. The final price, assembly quality, gearbox performance, actual consumption and after-sales service conditions play an important role in the buyer's decision. Also, if the price difference between the Tara Turbo and the regular version is large, it should be checked whether the increase in power is worth paying more for the owner's type of use.

The most important change of Tara V4 Turbo compared to the versions equipped with TU5P is the use of turbocharged EFP engine with a power of 160 hp and a torque of 240 Nm. This change increases the acceleration and traction capacity of the car and can provide a noticeable advantage in overtaking, hill climbing and driving with a full load.

On the other hand, the six-speed automatic transmission, the transmission of power to the front wheels and the overall structure of the suspension system are still preserved. For this reason, the Tara Turbo should be seen more as a serious powertrain upgrade than a car with a completely different architecture.

If the pricing and final quality match its technical performance, the Tara Turbo could be a significant option for buyers who prioritize more power. However, the final assessment should be made based on actual driving experience, maintenance cost and price difference with the TU5P versions.
