Honda created the VTEC (Variable Valve Timing & Lift Electronic Control) technology to increase a four-stroke internal combustion engine’s volumetric efficiency, which leads to better performance at high RPM and less fuel usage at low RPM. The VTEC system alternates between two (or three) camshaft profiles using hydraulic pressure. Ikuo Kajitani, a Honda engineer, created it. [1][2] It differs significantly from conventional VVT (variable valve timing) systems, which just alter the valve timings and make no adjustments to the camshaft profile or valve lift.

A VTEC engine: is it good?
Depending on how you drive, yes and no. The majority of drivers won’t notice their VTEC kicking in, but Honda automobiles with VTEC technology tend to be more efficient throughout a wider rpm range than many comparable vehicles, and they’re a lot of fun to drive in the appropriate circumstances. It only becomes operational when the engine is working at relatively high revs, which is uncommon under regular driving circumstances, especially if your vehicle has an automatic transmission. However, if you prefer driving on winding roads and you can adjust your own gears, VTEC makes a big difference.
A VTEC is it a turbo?
Under any circumstance, from city driving with frequent stopping and starting to highway travel, the VTEC TURBO engine is fuel-efficient. A 2.4L normally aspirated engine has a lot of torque for city driving due of its size. Due to its turbo, the VTEC TURBO engine has higher torque than the 2.4L normally aspirated engine. A 1.5L engine may perform on par with a 2.4L engine thanks to the VTEC TURBO technology.
Summary
Utilizing a turbocharger, direct injection system, and variable valve timing mechanism, Honda’s VTEC TURBO technology efficiently utilises every last drop of fuel.
Honda aims to mix driving pleasure with environmental performance with VTEC TURBO and hybrid technologies.
What does Honda’s VTEC stand for?
Honda’s VTEC (Variable Valve Timing & Lift Electronic Control System) engine eventually arose from the system. This ground-breaking technology, introduced with the 1989 Integra, stunned the world with a new level of performance from a small, fuel-efficient engine.
Which Civic engine is the best?
Even if high-rpm flogging is not necessary, it makes for storming fun as the 2.0L turbo 4-cyl. cranks out 306 hp before hitting the redline at 7,000 rpm. This VTEC engine is the most potent street-legal Honda to ever enter America, with a specified output of 153 hp/L.
VTEC: Does it use more fuel?
When Honda’s R&D team reached the first milestone with the REV (Revolution-modulated valve control) valve stopping mechanism, the enormous effort of creating a smarter engine officially began. The system was designed to be able to shut down several valves at once in order to maximize airflow, provide stable idling, and improve smoothness for low- to medium-powered engine operation. The Honda CBR400F motorcycle used this brand-new advancement for the first time in 1983. Honda then set out to innovate the four-wheel drive after greatly improving the 2-wheelers.
Honda created the DOHC (Double Overhead Camshaft) VTEC system for autos from the REV used in motorcycle engines. A four-stroke internal combustion engine’s volumetric efficiency was increased by the DOHC VTEC, leading to stronger performance at high RPM and decreased fuel consumption at low RPM. The VTEC technology has completely altered the way the world views engines since it was originally introduced in 1989.
The VTEC engine made its debut in India in 2000 and has since established a legacy. The VTEC system had numerous upgrades over the years, with i-VTEC being the most significant (where “i stood for intelligent). The VTC (Variable Timing Control) and VTEC processes were combined in this technology to offer a very effective and excellent performance.
VTEC or turbo: which is superior?
While VTEC is more focused on extracting the maximum amount of horsepower from the engine because torque on VTEC cars can only be felt on the VTEC range, which is anyplace after 5,500RPMs, the torque produced by a turbo is still negligible in comparison.
What makes VTEC engines unique?
In essence, the VTEC system blends high-RPM performance with low-RPM fuel efficiency and stability. Additionally, the changeover happens smoothly, enabling consistent performance across the entire powerband. The engine computer manages the switching process between the two cam lobes.
VTEC vs i-VTEC: Which is superior?
Honda added i-VTEC, which effectively stands for Intelligent VTEC, for you if variable valve timing wasn’t hard enough before. Since its introduction in Honda vehicles in 2001, almost all of their performance engines have utilised it.
The above-mentioned architecture is used in conventional VTEC engines. Only the lift and duration offered by the two distinct camshaft lobes or profiles can be controlled by this technique. In order to have better control over valve timing, Honda created and combined what is known as i-VTEC, or VTC with VTEC.
Variable timing control (VTC) allows the camshaft to be advanced or retracted in order to manage valve overlap. The exhaust valve never opened and closed simultaneously in conventional VTEC engines because the intake valve always opened first. With VTC, the camshaft lobe angles can be adjusted to allow the valves to overlap or open simultaneously. It can be altered at various RPM levels due to its changeable nature.
So, What’s the Difference Between VTEC and i-VTEC?
By allowing for camshaft angle modifications, i-VTEC adds more valve timing control. The valves must open and close differently for each RPM range in order to operate at their peak performance at both low and high RPMs. The main distinction between VTEC and i-VTEC is that the former does this.
In contrast to the conventional VTEC, i-VTEC offers a smoother power band and improved performance at both high and low RPMs.
Does VTEC exist in all Civics?
Three separate Honda Civic models all have one of the two available VTEC-equipped engines that are available for new Honda Civics. The two engines in question are both four-cylinder, lightweight K20 engines, which are well respected for their performance. The small four-cylinder engines developed by the K20 series are possibly the best ever made, including astounding power-to-weight ratios, cleverly simple designs, and incredibly high reliability.
The naturally aspirated K20C2 in the base trims of the Civic sedan and the turbocharged K20C1 in the Civic Type R are the two K20 engines that make use of VTEC in the 2021 Civic. The K20C2 maximizes engine efficiency by using an updated i-VTEC technology for both the intake and exhaust valves. The K20C1 uses VTEC only on the engine’s exhaust side, while a turbocharger forces air into the engine’s intake side at a high pressure. This configuration places a high priority on power and increases the engine’s horsepower and torque without requiring more displacement.
The most dependable Honda engine is which one?
The B18C6 is one of the best-rated Honda VTEC engines. This 1.8L 4-cylinder engine was installed in Honda Integra and Acura Integra Type R models sold worldwide from 1999 to 2001. For a car that was so light, its 195 horsepower and 130 pound-feet of torque were excellent. Additionally, it had a redline of 8400 RPM, while VTEC began to operate at 5700 RPM.
Because it was simple to alter and had that distinctive DOHC VTEC sound when you approached the VTEC engagement point, the B18C platform rose to great popularity. This results in a lot of power in the higher RPM ranges, making the cars they are in feel sportier and more enjoyable.
The B18C is still recognized as one of the best VTEC motors ever made, and it continues to be in high demand all over the world. If you’re looking for an excellent, low-mileage B18C, be prepared to pay more.

Driving without VTEC is possible.
Yeah. Unplugged VTEC results in no solenoid engagement, a lower lift cam, a worse breathing engine over 6,00 RPM, less air, more fuel, and an extremely rich engine over 6,00 RPM. Therefore, there was no harm or knock.
Has VTEC been retained in new Hondas?
Other Honda vehicles from 2018 and 2019 come with i-VTEC Honda engines, which boost the engine’s efficiency by adding Variable Timing Control.
Honda stopped utilizing VTEC when?
The 2017 Honda Civic Si will include a turbocharged engine, which is a first for the trim, and will go on sale next month for around $20,000. The 1.5-liter engine has the same 205 horsepower as the old 2.4-liter four with naturally aspirated gas. However, compared to the normally aspirated engine, torque is up 18 lb-ft to 192. The Civic Si should be enjoyable to drive because it has more power accessible lower in the rpm range and a standard six-speed manual transmission.
A sport-tuned suspension with firmer springs and antiroll bars helps to improve car control. Honda claims the new Si is substantially lighter than the previous version (without providing details). A two-mode adaptive damper system (sport and normal), a limited-slip differential, and larger 12.3-inch front brake rotors are all included as standard equipment.
The coupe and sedan both feature subdued design (at least compared to the Type R). The Si gets wider side vents at the back, black trim on the front fascia, 18-inch, 10-spoke wheels, and center-exit exhaust. No flashy body kits or extraneous wings are present.
It will be interesting to see how the 2017 Civic Si stacks up against rivals like the Ford Focus ST, Subaru Impreza WRX, and Volkswagen Golf GTI. With starting costs in the mid-$20,000 range and greater power than the Si, the competition may damage Honda’s new Si. Alternately, the Si could triumph despite lacking VTEC. As soon as we can get behind the wheel, we’ll let you know.
Which automobiles feature VTEC?
The 1.8-liter engine in the HR-V, however, uses VTEC to regulate the timing of both intake valves at higher speeds and one intake valve at lower speeds, but not lift.
Although the intake and exhaust valves in Honda’s turbocharged four-cylinder engines have variable valve timing, the lift valves do not. According to Honda, this variation of VTEC controls the intake and exhaust camshafts separately, enabling valve timing to be adjusted for a range of driving circumstances. The Accord, Civic, Civic Si and Type R, and CR-V all employ this technology.
The Odyssey, Passport, Pilot, and Ridgeline’s V-6 engines have variable intake valve lift and timing, and VTEC combines with cylinder deactivation to function in a three-cylinder mode.
