Difference 2.0 4Cyl/2.8 6 Zyl

After a few thousand kilometers with the 2.8, I find some facts that you might comment on or confirm. 1. the charge indicator in the 2.8 is less in the impact than in the 2.0. i.e. the needle moves far less, the optical bench area is very scarce. Is that so? 2. the 2.8 sings with certain touring numbers and in thrust mode. 3. the agility of the gas is identical. 4. the consumption is one litre higher at 2.8. 5. the 6 gear gear has a hole between 3th and 5th when switching down and 2th, i.e. the gearbox remains much less long in the 3rd and jumps much faster in the 2nd than in the 5th. 6th when ignition in cold condition, the 2.8 goes almost on 1500 tours and bleachs that until the activity log in. That was not so at the 2,0. Greetings from the cap
