Are VVTi engines good?

The VVTi mechanism is not unique to the land cruisers. It’s pervasive across the whole lineup of toyota’s and has proven it’s worth reliability in power and gas efficiency. Look at the pros – more power and efficiency across the board. That’s not something to be taken likely for a heavyweight car like the Land Cruiser.

Is VVTi better than VTEC?

VTEC (Variable Valve Timing and Lift Electronic Control) is a valvetrain system developed by Honda that allows engines to achieve turbo level specific output without the bad fuel efficiency that turbocharging normally introduces.

What are the benefits of VVTi?

VVT-i advantages include increased torque and output, better fuel economy, and reduction of nitrogen oxide (NOx) and hydrocarbon emissions. The simple structure of the VVT-i makes it extremely reliable and easy to adapt for existing engine designs.

Which is better VVT or CVT?

Lift is employed solely as a performance measure and so is also not something that would be considered efficient.

At what RPM does VVTi kick in?

It’s counterpart, the 2zz-ge, which is the engine used in the GT-S, has the VVTL-i technology. That extra “L” in there gives you the kick at 6000 rpm’s (6200 in later models), known only as lift.

Are VVT engines bad?

Engine Performance Problems

A malfunctioning VVT solenoid can prevent the valve timing from advancing or retarding as needed. As a result, the engine may exhibit performance problems, such as rough running and poor acceleration.

Does VVT make a car faster?

Benefits of VVT

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.
