Dear members, first of all sorry for my poor English.
After several years with Toyota hybrids and a Kia Niro, I bought one month ago a Jazz in the top version Executive.
It is a very good piece of engineering, better than all the HEV I had before and drove.
Have around 1350 Km and my first consumption was BC 3.2 L in 760 Km and real in the Sprit Monitor 3.44 L.
I usually fuel around 1/4 tank. The autonomy in BC was still more than 300 Km.
In this second tank have already 350 Km and the BC indicates 3.2L again.
The autonomy according to BC is more than 1100 Km
Hot weather helps also a lot.
It is a shame that so few people know how good the Jazz is and bought only image with BMW, Audi, Mercedes, etc.
