What is Honda VTEC? What does VTEC mean in Honda? VTEC (described as Variable Valve Timing & Lift Electronic Control, but stands for Valve Timing Electronically Controlled) is a system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine, resulting in higher performance at high RPM, and lower fuel consumption at low RPM.
The VTEC system uses two (or occasionally three) camshaft profiles and hydraulically selects between profiles. It was invented by Honda engineer Ikuo Kajitani. It is distinctly different from standard VVT (variable valve timing) systems which change only the valve timings and do not change the camshaft profile or valve lift in any way.
What is Honda VTEC?
Variable Valve Timing and Lift Electronic Control is the abbreviation for Honda VTEC. It is a technology created by Honda to increase a four-stroke internal combustion engine’s volumetric efficiency, leading to better performance at high RPM and less fuel usage at low RPM.
Two distinct camshaft profiles are used by VTEC for each intake and exhaust valve. The engine operates on a low-lift camshaft profile at low RPM, which offers good fuel efficiency and emissions. The engine changes to the high-lift camshaft profile at high RPM, which produces additional torque and power.
The engine computer operates the VTEC system by monitoring the engine’s RPM, load, and temperature via a variety of sensors. The computer will switch to the high-lift camshaft profile when the engine reaches a specific RPM and load.
The Civic, Accord, and CR-V are just a few Honda engines that feature VTEC. Some Acura models, like the Integra and TL, also make use of it.
The advantages of Honda VTEC include the following:
- Enhanced efficiency at high RPM
- Reduced fuel use at low RPM
- Lower emissions
- Improved engine performance
- Increased engine toughness
Although VTEC is a sophisticated system, it significantly enhances the efficiency and performance of Honda engines. It is just one of many factors that contribute to Honda’s reputation for producing some of the best engines in the world.

VTEC is frequently connected with high-performance Honda automobiles and has even developed a bit of a cult following among auto enthusiasts.
What is so special about Honda VTEC?
Because technology enables Honda engines to have both strong performance and exceptional fuel efficiency, Honda VTEC is unique. For each intake and exhaust valve, two distinct camshaft profiles are used to achieve this. The engine operates on a low-lift camshaft profile at low RPM, which offers good fuel efficiency and emissions. The engine changes to the high-lift camshaft profile at high RPM, which produces additional torque and power.
The engine computer, which uses a number of sensors to gauge the engine’s RPM, load, and temperature, is in charge of this system. The computer will switch to the high-lift camshaft profile when the engine reaches a specific RPM and load.
Honda uses VTEC in a wide range of engines, including small four-cylinder and large six-cylinder models. Some versions of Acura also make use of it.

Honda vehicles that utilise VTEC include the following:
- Honda Accord
- Honda Civic
- Toyota CR-V
- Acura Integra Honda Civic Type R Honda S2000 Acura TL
Honda vehicles with VTEC are an excellent choice if you’re looking for a vehicle with a strong and effective engine.
Did Honda stop making VTEC?
Honda is phasing down VTEC in favor of alternative technologies, however it is still being produced. Since its initial introduction in the 1980s, VTEC has been incorporated into a number of Honda engines. However, Honda has been working on new technologies recently that can complement VTEC, such as direct injection and turbocharging.
As a result, Honda is currently replacing VTEC in some of its engines with these new technologies. For instance, the 2.4L VTEC engine from earlier models is replaced by a 1.5L turbocharged engine in the 2023 Honda Accord.
However, certain of Honda’s engines, including the 2.0L engine in the 2023 Honda Civic Si, still use VTEC. Furthermore, it is unknown if Honda intends to entirely discontinue VTEC in the future.
VTEC is a terrific technology all around that has contributed to Honda engines being some of the best in the world. VTEC usage, however, is probably going to decline as Honda creates new technologies.
Are VTEC engines good or bad?
In general, VTEC engines are regarded as being good engines. They are renowned for their dependability, performance, and fuel economy.
For each intake and exhaust valve on VTEC engines, there are two distinct camshaft profiles used. The engine operates on a low-lift camshaft profile at low RPM, which offers good fuel efficiency and emissions. The engine changes to the high-lift camshaft profile at high RPM, which produces additional torque and power.
The engine computer, which uses a number of sensors to gauge the engine’s RPM, load, and temperature, is in charge of this system. The computer will switch to the high-lift camshaft profile when the engine reaches a specific RPM and load.
Honda uses VTEC engines in a wide range of cars, including small four-cylinder and large six-cylinder models. Some Acura vehicles also employ them.
VTEC engines do, however, have a few drawbacks:
- Compared to non-VTEC engines, they may be more difficult and expensive to manufacture.
- Compared to non-VTEC engines, they could need servicing more frequently.
- Compared to non-VTEC engines, they could be more prone to oil leaks.
VTEC engines are generally good engines that have a variety of advantages. Before buying a car with a VTEC engine, one should take into account some of its drawbacks.
Your specific requirements and financial situation will determine whether or not a VTEC engine is suitable for you. Honda vehicles with VTEC are an excellent choice if you’re looking for a vehicle with a strong and effective engine. However, you can want to take into account a non-VTEC engine if you’re looking for a vehicle with a straightforward and dependable engine.
