VTEC and Honda’s VTC (Variable Timing Control), a continuously variable camshaft phasing technology used on the exhaust camshaft of DOHC VTEC engines, are combined in the Honda i-VTEC (intelligent-VTEC) system. In 2001, Honda’s K-series four-cylinder engine family debuted the technology. By the 2002 model year, all four-cylinder Honda or Acura vehicles marketed in the US used i-VTEC, with the 2002 Honda Accord being the sole exception.
The exhaust camshaft can now advance between 25 and 50 degrees, depending on the engine configuration, however the VTEC controls of valve lift and valve duration are still only available for distinct low- and high-RPM profiles. A computer-controlled, oil-driven, adjustable cam sprocket is used to implement phasing. VTEC is impacted by both engine load and RPM. At idle, the exhaust phase is completely retarded; at high throttle and low RPM, it is substantially advanced. Further torque output optimization results, particularly at low and middle RPM. Two distinct i-VTEC K series engine types are described in the next section.
The J-Series SOHC engines from Honda have a completely separate system that is also confusingly referred to as i-VTEC. To increase fuel efficiency when operating under light loads, Honda J-Series engines equipped with i-VTEC combine SOHC VTEC operation with Honda VCM (Variable Cylinder Management) variable displacement technology.

What makes VTEC and i-VTEC different from one another?
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.
What does the I in i-VTEC stand for?
The original VTEC technology was enhanced by Honda and eventually became the Honda i-VTEC (intelligent-VTEC). The majority of Honda 4-cylinder automobiles employed i-VTEC by 2002 after this technology became widely accessible in 2001. The i-VTEC technology combines Honda’s VTC and the original VTEC (Variable Timing Control).
Are Honda i-VTEC engines reliable?
The petrol engines made by the Japanese carmaker are excellent. One of the most effective engines in the nation is the i-VTEC series. Cars like the Honda City and Jazz, which are powered by this engine, have long dominated their respective segments. An technical marvel known as VTEC, or Intelligent Variable Timing and Electronically Controlled, uses two camshaft profiles, one for low RPM for good torque and better driving, and the other for higher RPM. The engine’s power output is increased as a result. The i-VTEC, which is more oriented on fuel efficiency, is the VTEC that Indian Hondas receive. Later, we shall return to this.
The Honda i-VTEC engine is it turbo?
Turbo engines are typically thought of as having “great power, low fuel economy,” however Honda’s VTEC TURBO engine achieves fuel efficiency without sacrificing the pleasure and quality of the ride.
The 1.5L VTEC TURBO maintains all the advantages of a compact engine in terms of fuel efficiency while adding a turbocharger, direct injection, and variable valve timing. Because of this, it generates power that feels smooth from low to high revs, outperforming the torque of a 2.4L engine. Acceleration remains thrilling as a result on all types of roads, from city driving to motorways and even mountainous climbs.
Is i-VTEC quick?
Honda developed the i-VTEC technology, also known as intelligent variable valve timing and lift electronic control, to reduce the amount of fuel used by Honda automobiles. The VTEC system switches between two camshaft profiles hydraulically.
The engine can effectively have numerous camshafts thanks to Honda i-VTEC. With this technology, however, the engine’s computer has the ability to vary the cam timing and activate different camshaft lobes as the engine passes through various RPM ranges.
The amazing aspect of this technology is that it allows for the simultaneous use of high- and low-speed camshafts in the same engine. The basic goal of Honda i-VTEC is to achieve maximum engine performance throughout the whole RPM range.
Which is superior, VTEC or Turbo?
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 VTEC engine is the best?
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.
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.
Does Honda outperform Toyota?
Toyota has more automobiles, better costs, and higher reliability in the categories we looked at, making it the superior brand. When deciding between Honda and Toyota, Honda isn’t a slouch either thanks to its comparable dependability ratings, reasonable costs, and even higher safety ratings.
VTEC’s fuel economy?
“High power, low fuel economy” used to be the standard for turbo engines. The Honda VTEC TURBO is a modern engine that offers a smooth ride while still being fuel-efficient.
The 1.5L VTEC TURBO maintains all the fuel-saving advantages of a tiny engine plus, via the use of a direct injection system, variable valve timing, and a turbocharger, generates power that is smooth from low revs to high revs, outperforming the torque of a 2.4L engine. Acceleration is thrilling on every route, including motorways, mountain slopes, and city streets.
Additionally, the 1.5L VTEC TURBO is engineered to run effectively on ordinary fuel so that even more users can benefit from its features.
Does VTEC increase a car’s speed?
Honda created the Variable Valve Timing & Lift Electronic Control (VTEC) technology to improve the overall performance, efficiency, and fun factor of their vehicles. The technology has become a well-known meme as a result of its frequent use in Fast and Furious movies. Few people are aware of the mechanics behind the expression “VTEC just kicked in, yo!” What you need to know about the system is provided here.
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.
What VTEC engine has the fastest speed?
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.
