- Does tiago AMT gives less mileage compare to normal tiago?
- Will tiago AMT give less mileage if driven in manual mode compare to normal tiago?
- Whether maintenance cost of tiago AMT higher then normal tiago?
- How many years AMT will work in good condition?
- Is it difficult finding mechanic for AMT cars repair in emergency case?
- Whether AMT cars as effective as normal car when driven in manual mode?
- Can AMT cars safely driven at high speed around 90kmph?
- Does AMT system gets affected if most of the time car driven in manual mode?
Looking forward your reply. Thank you.
AMT = Automated Manual Transmission.
A key piece of information for you would be that an AMT is simply a Manual Transmission with a hydraulic shifting mechanism on top that can be controlled by the computer. That said, the only differences arise from this mechanism.
Theoretically, the mechanism will be consuming energy and experiencing wear, so the mileage may go down and maintenance may go up if usage patterns are absolutely identical (improbable). However, it is likely even these differences will make no practical or noticeable difference in real life. Rather, if the computer program is designed to maximize fuel economy, it would often outsmart humans for better results.
There is no reason for an AMT to be less capable than a manual at speed, provided it has the same gear ratios. Also, when you drive it in manual mode, you're simply telling the computer when to shift, rather than it telling itself when to shift - so this wouldn't affect it much either, unless your shift pattern is very harsh.
All things considered, an AMT is slightly more complex (mostly by virtue of electronics) than the equivalent manual, but that can be said for almost any technological development - even central locking. As to whether this marginal complexity is a worthy trade off for the convenience, is up to you.
