What is I Vtec? Honda Vtec vs i-Vtec

Though most of Honda users and automobile enthusiast have heard the term i-Vtec, most of us don’t know the details about it. So, let’s check what I Vtec is.

i-Vtec is a system used in Honda engines that alters timing and lift of the intake valves. The system allows for better fuel economy and efficiency by optimizing valve lift and timing. The system was first introduced on the 1999 Honda Accord V6 engine.

In this article, we know the details of I Vtec system, and learn how it works, why it is important. Again we will compare i-Vtec with Honda’s preceding technology Vtec.

What does i-VTEC stand for?

i-VTEC stands for “intelligent” Variable Valve Timing and Lift Electronic Control. It is intelligent and advanced version of Variable Valve Timing and Lift Electronic Control (VTEC) system found on previous Honda engines. So, we found that the “I” in I-VTEC stands for “Intelligent”. The Intelligent part of I-VTEC is the addition of VTC, or Variable Timing Control.

It is an advanced system that controls both the timing and lift of the valves in an engine. The system uses sensors to monitor conditions inside the engine, and then adjusts the timing and lift of the valves accordingly. This helps to improve fuel economy, while also providing more power when needed. I-VTEC also helps to reduce emissions.

VTC allows the timing of the intake valves to be continuously adjustable, based on engine speed. This gives the engine much greater flexibility in how it produces power. The result is an engine that produces more power and torque at lower rpm than a non-I-VTEC engine, while still getting good fuel economy.

Vtec vs i-Vtec

When it comes to choosing between I-VTEC and VTEC engines, there are a few key things to keep in mind. Both engine types are incredibly powerful, but they have different strengths and weaknesses. Here’s a quick rundown of the main differences between these two engine types:

VtecPerformance focusedRepeated Oil Changing required
Engine Vibration tendency
i-VtecEfficiency focused

The I-VTEC engines feature variable valve timing on both the intake and exhaust valves. This allows for more precise control over the timing of the engine’s combustion cycle, resulting in increased power and efficiency.

I-VTEC engines also tend to be smaller and lighter than VTEC engines, making them ideal for use in smaller vehicles. VTEC: – VTEC engines feature variable valve timing on just the intake valves.

This helps improve airflow into the engine, resulting in increased power. However, it can also lead to increased fuel consumption.

What is Better Vtec Or I-Vtec?

There are a few key things to consider when trying to decide if VTEC or i-VTEC is better for you. The main difference between the two technologies is that VTEC is more focused on performance, while i-VTEC is more fuel efficient. So, if you’re looking for a car that’s going to be fast and powerful, then VTEC is probably the way to go.

However, if you’re looking for a car that’s going to get great gas mileage, then i-VTEC might be the better option. Another thing to keep in mind is that VTEC engines tend to be more expensive than i-VTEC engines, so that’s something else to factor into your decision. Ultimately, it comes down to what your priorities are and what you’re willing to spend.

If you want the best of both worlds, then getting a car with both VTEC and i-VTEC would be the way to go.

Does I-Vtec Make a Car Faster?

i-VTEC is a system that Honda uses in its engines to improve performance. The system works by changing the timing and lift of the valves based on engine speed and load. This allows for better fuel economy and performance at high engine speeds. So, does i-VTEC make a car faster?

In general, yes. The system is designed to improve performance, so it will typically make a car faster than one without i-VTEC. However, there are many other factors that affect how fast a car can go, so it’s not possible to say definitively that all cars with i-VTEC will be faster than all cars without it.

What is Special About I-Vtec?

The Honda i-VTEC system is one of the most technologically advanced engines available today. This system adjusts timing and lift of the intake valves to produce more power and torque while still maintaining excellent fuel economy. The result is an engine that provides both power and efficiency, making it a great choice for those who want the best of both worlds.


I Vtec is a type of engine that uses two different types of valves to increase performance. The first type of valve, known as the intake valve, opens to let air into the cylinder. The second type of valve, known as the exhaust valve, opens to let exhaust out of the cylinder.

I Vtec engines use both intake and exhaust valves to improve performance by increasing airflow into and out of the cylinders.
