Kelisa
25km/l
mostly highway during morning and night (rarely use AC), no power steering
Can't really say max mileage but usually fill up around 600+ @ 25l

Well there are drawbacks la. If I crash the Kelisa very likely will die or serious injury. That crane which fell on that lady's Kelisa, the damage certainly dun make me feel good. Other car she might have survived. Looking at other Kelisa accident pics, the A pillar and roof definitely made of paper. Good FC is a plus, but I rather take the safety offered by modern cars.

Also no AC makes the biggest difference. Not really practical for most people. I drive early morning and night so can survive, but running AC reduces it to like 450+ km per tank. Power steering I just removed the belt. To me it barely makes a difference except when parking. Prefer the more direct feel.

Not really since all of them were made with these features. And they don't really cost much anyway. The number of people wishing for Kelisa GTE not enough for them to consider making one.
