What does Valvematic engine mean?
Dubbed Valvematic,;it combines the automaker’s existing VVT-i variable valve timing setup;with a mechanism that constantly controls the intake valve lift volume. Valvematic helps optimize performance and fuel efficiency by adjusting airflow volume based on the engine’s operating conditions.
Is Valvematic better than VVTi?
Neither Valvematic or VVTi increases maximum power. What they both set out to do is allow a more highly tuned engine to still be usable below that high output portion of the rev band. VVTi does it by changing valve duration, Valvematic adds valve lift and fuel control.
What is Toyota Valvematic technology?

Are VVT engines good?
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.
Is VVTi good or bad?
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.
