What is the difference between vvtec and VVT-i?

VTEC vs. VVT-i. 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. VVT-i ( Variable Valve Timing with intelligence) is a similar system developed by Toyota…

What does VVTi mean on a Toyota?

Toyota uses VVTi (Variable Valve Timing with intelligence). As the name describes itself, the technology varies only the timing of the intake valve. If the valve was open for, let’s say; 2 seconds, it will now open for 4 seconds after VVTi is engaged.
