Yes, one is transmission technology(CVT) and other being Engine Valve(VVT) technology.2015-09-02
Is a VVT engine good?
There are many benefits to using VVT and virtually no drawbacks. One benefit is an increase in maximum engine speed (and therefore more peak power) – as much as a 25% increase. Low speed torque is also increased, providing better handling and drivability.2014-07-01
Which is better VTEC or VVT?
VTEC VVT-i

What is so bad about CVT transmission?
They are noisy: No driver welcomes extra noise unless they are cruising on a powerful engine. CVTs have the tendency to hang at high rpm, which causes the engine to rev wildly under acceleration. Even if you chose CVT cars programmed to emulate stepped up gears, the noisy operation of the CVT just won't go away.2019-07-19
How does a VVT transmission work?
The variable valve timing, or VVT, allows for a phase shift in the timing of the valve opening and closing. It does this by offsetting the camshaft at a relative angle to the timing chain. The VVT gear is a fixed gear when there is no timing advance or retard.2017-11-09
Is VVT and CVT the same?
Yes, one is transmission technology(CVT) and other being Engine Valve(VVT) technology.2015-09-02
How does Toyota VVT work?
The system works by using a variable-speed head for the camshaft. ... This increases or decreases the speed of the camshaft in relation to the engine's drive timing. That, in turn, changes the duration of the valve lifting to control intake and exhaust.
What is a VVT transmission?
VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing technology developed by Toyota. The Toyota VVT-i system replaces the Toyota VVT offered starting in 1991 on the 5-valve per cylinder 4A-GE engine. The VVT system is a 2-stage hydraulically controlled cam phasing system.
Why most CVT cars are terrible?
They are noisy: No driver welcomes extra noise unless they are cruising on a powerful engine. CVTs have the tendency to hang at high rpm, which causes the engine to rev wildly under acceleration. ... Poor feel: You won't feel it when the CVT vehicle shifts gears because it has no gears in the first place.2019-07-19
Is dual VVTi CVT?
That's because the subcompact sedan has just received new NR-series Dual VVT-i engines and a continuously variable transmission. ... According to Toyota Motor Philippines, the new engines have better fuel economy thanks to dual variable valve timing.2016-07-29
What is the difference between VVT and VVTi?
i-VTEC uses not only timing but also the lift aspect of the valves, while VVTi uses only the timing aspect. The technology that uses timing and lift aspect developed by Toyota is called VVTL-i and can be equated with that of i-VTEC of Honda.
