Why does Allion have much better FC than Vios?

[Ldawn88]

Axio 1.5 and Allion 1.5 are on VVTi, not Dual VVTi.

 

Allion 1.8 is on Dual VVTi.

Read somewhere that Allion and Axio using Dual VVTi engine while the Tom Yam Vios using single VVti engine. What that means is not clear to me, but could account for the difference in fuel economy. The same article also mentioned that CVT allows for infinite number of gear combinations, such that the processor can find the optimum gear to use for the particular engine condition. For the standard 4 speed automatic, the use of traditional fluid drive technology leads to inefficiencies.

 

I'm just relating what I read, so don't shoot me if this is wrong ok. Other bros care to validate or refute this???

The 1.8l Allion is using dual vvti

 

The 1.5l Allion is single vvti, 1NZFE engine same as Vios

 

Its true Allion using CVT and Vios using 4 speed auto and CVT is generally seen to be better than 4 speed auto in fuel efficiency

 

From what I know Toyota Japan generally uses CVT for all new non performance cars

Allion has better engine efficiency and design. Simple logic

 

Allion and vios from same company Toyota designers, how come so much different, tink toyota should fire vios engine designers

which means Allion sacrifice percormance to gain FC,

anyone know where can get Allion test drive, I would like to try out what's different from vios, btw I quite appreciate vios's sprant

i read that article before.

But surprisingly, i didnt manage to find anything on that when i googled it.
