VVT–i
Toyota's award–winning Variable Valve Timing with Intelligent (VVT–i) technology utilises a sophisticated computer to vary the air intake valve timing according to driving conditions and engine load.
By adjusting the overlap time between the exhaust valve closing and intake valve opening, the engine characteristics can be changed to provide instant engine torque across the entire rev range. This gives the best of both worlds: Powerful acceleration and superior fuel economy. In addition, more complete fuel burn at a higher combustion temperatures leads to fewer emissions.
