What is the Corolla Altis Dual VVT-i about?
The Indonesian market has a firm relation with Toyota vehicles and Japanese manufacturer has dropped yet another variant of the best selling Corolla Altis in the market.
The 2.0 Dual VVT-i variant features only a new radiator grille, but only when you open the bonnet you find the rational explanation to the word “Dual” on the badge.
Who the heck is Dual VVT-i? Is this the same case as Hero Honda Splendor and Splendor+ with fuel tank stickers seperating the two?
Generally, the term dual on a car is implied as a dual-fuel engine that is capable of handling fuels of different nature. But not this one though.
The Dual VVT-i is two VVT-i meaning both the inlet and exhaust valves obtain variable valve timing capabilities. The regular Corolla Altis, like the one sold in India is equipped with VVT-i only for the intake valve, so only the volume of mixture entering the engine can be controlled by altering the duration of valve in open condition.
According to you, what could be the advantages?
With the Dual VVT-i technology, the flexibility is enormous, and the regulated delay and advancement of the exhaust valve timing improve throttle response and minimize fuel wastage and emissions brought about by it. At lower revs, the valve shuts sooner and at higher revs it is otherwise. The driver will be able to feel the change.
