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.
What is Honda VTEC?
June 20, 2020. Variable valve-timing system, or VTEC, has been a feature of Honda and Acura vehicles since 1989. The 1991 Acura NSX was the first vehicle in the United States to feature VTEC, which is an acronym for variable valve timing and lift electronic control.
What distinguishes VTEC from non-VTEC?
A new valvetrain system called VTEC (Variable Valve Timing and Lift Electronic Control) was created by Honda to give users a more adaptable driving experience. Before VTEC, non-VTEC engines could only be set up for one camshaft profile. It is possible to adjust this so that it performs better at high or low RPMs. Depending on how the car is being utilized, VTEC enables the engine to transition between two camshaft profiles.
For everyday driving, low RPM optimized camshafts make more sense because they offer improved fuel efficiency and rapid acceleration at low speeds. It is more aggressive and typically reserved for usage in racing to optimize for high RPMs. If your engine is tuned for high RPMs, it will burn a lot more gasoline and be less responsive at low speeds. However, the increased power at high RPMs, which can easily convert into a considerably higher top speed, more than makes up for this. Non-VTEC engines can only be optimized for one of these two situations, however VTEC engines can have the best of both worlds. VTEC accomplishes this by electronically switching profiles in response to other conditions. The VTEC engine employs a number of variables, including the vehicle’s speed and engine RPM, to determine when to switch profiles.
It’s simple to assert that non-VTEC engines are widely available on the market, coming from various automakers and suppliers. On the other side, Honda is the only manufacturer of VTEC engines and their associated cars. Although they go by a different name, other automakers do have alternative technologies that mimic VTEC’s capabilities in their cars.
There is no debate between VTEC and non-VTEC engines when purchasing a vehicle intended for daily driving. VTEC engines give you more versatility and are capable of meeting your needs. Given today’s quickly growing gasoline prices, VTEC engines may initially cost you a little bit more, but they will more than make up for that additional expense in fuel savings.
Summary:
1. In contrast to non-VTEC engines, VTEC engines have two camshaft profiles.
2. Non-VTEC engines can only be optimized for either high or low performance with VTEC engines, whereas
3. Only Honda vehicles feature VTEC, whereas non-VTEC models are available from all automakers.
Does i-VTEC equate to VTEC?
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.
VTEC is present in the 2003 Honda Civic EX?
The outstanding VTEC (Variable Valve Timing and Electronic Control) system from Honda gives the EX engine—which has the same 1.7 liters of displacement as the DX and LX engines—a boost.
D17A has a VTEC?

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 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 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.
Which Civics have VTEC?
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.
