I bought a Townace Noah and it travels so good. I guess to answer all of you, it happens that when you accelerate more, the more fuel consumption becomes high i mean this happens to every car. When you drive with a normal speed, less fuel consumption. Toyota Townace Noah has 4x2 and a Full-Time 4x4, unless someone says something who knows better than i do. This is why there are no 4x4 buttons/Lever and or even a simple diff lock to a 4x2. All I can say is, the less you press an accelerator, the more you are going to same fuel. My only problem is I can see nor feel the fouth gear when it engages, its as if i'm always driving with the 3rd gear. Enjoy your vehicles guys.
