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.
Are VVT engines reliable?
The Dual VVT-i 4.0 V6 engine found in the 09+ models are
smooth, quiet, and reliable
with engine longevity easily reaching over 200,000 miles (320,000 km). It's no secret that regular maintenance and using high grade oils and lubricants is the key to reliability on almost any engine.
What is the benefits of VVT engine?
Higher RPM – The main advantage of having a variable valve timing technology is the
increase it will provide in your engine's revolutions per minute
. When you step on the gas pedal to accelerate the vehicle faster, it will require more RPM to sustain this demand.
Does VVT make a car faster?

Which is better VVT or VTEC?
VTEC VVT-i | Launched 1983 1996 |
---|
What RPM does VVT kick in?
Blue is VVT, Red is VVT disconnected. VFR800's VTEC kicks in at
6,400 or 6,800 RPM
, depending on year. Unlike Honda's automotive VTEC, the VFR's VTEC also doesn't change valve timing at all; it engages a second intake and exhaust valve – which stay closed before the activation threshold – in each cylinder.
Which cars have VVT engines?
- Alfa Romeo – Twinspark technology.
- Audi – VVT.
- BMW – Valvetronic, VANOS and Double VANOS.
- Ford – Variable Cam Timing.
- GM – Double Continuous Variable Cam Phasing (DCVCP), Alloytec and Variable Valve Timing (VVT)
- Honda – VTEC, iVTEC and VTEC-E.
- Hyundai – MPI CVVT.
- Lexus – VVT-iE.
What VVT 1 engine?
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.
What does VVT mean on a car?
VVT-i stands for
Variable Valve Timing-Intelligence
, which is Toyota's name for the variable valve technology it uses in most of its vehicles.
What does HEMI VVT mean?
Some may have noticed the acronym at the end of each engine, “VVT.” That stands for “
Variable Valve Timing
”, technology developed for automotive systems, mainly the engines, to optimize its horsepower and even help with fuel efficiency.
Is VTEC bad for engine?
Not hitting vtec ATLEAST once a day can cause both problems
to the driver, and the car. Without hitting vtec daily- the driver can develop a “light” foot. The car also suffers because it enjoys crossing over the line at 6000 RPM and making that nice growling noise.
Does VTEC make a car faster?
Honda developed its Variable Valve Timing & Lift Electronic Control (VTEC) technology to make its
cars quicker
, more efficient, and more enjoyable to drive overall.
Which engine is best in India?
- Maruti's 1.2L K-Series. The familiar 1.2-litre K12 engine has been around since eleven years now, but it's still a gem of a motor. …
- Honda City's 1.5L Vtec. …
- Skoda Octavia vRS' 1.8L turbo. …
- Ford's 1.5L diesel. …
- Fiat's 1.3L MJD. …
- VW's 1.2L TSI. …
- Maruti's 1.6L diesel.
Does the VVT engine have a timing belt?
Variable Valve Timing (VVT) is a technology that's used on many late model engines to improve fuel economy, idle smoothness, emissions and performance. … Ideally, valve timing should change with engine speed and load like ignition timing does. But with
a standard cam drive (belt, chain or gears), that is not possible
.
Does VVTI have lift?
Variable valve lift (VVL) and variable valve timing (VVT) are two of the most popular ones. … Variable valve lift is mainly used to enhance performance. Instead of having one cam profile for the entire rev range, a VVL engine has two:
low-lift and high-lift
.
What is Chevy VVT?
Chevrolet's VVT system uses
electro-hydraulic actuators between the drive sprocket and camshaft
to twist the cam relative to the crankshaft position. Adjusting the cam phasing in this manner allows the valves that are actuated by that camshaft to be opened and closed earlier or later.
