The fact is :

Proton Inspira using engine same as lancer. The engine coded with 4b11 at engine bay. But the ECU is tuned same with the Mitsu ASX for better fuel consumption. Inspira is tuned for family car anyway. For those who didnot know yet., ASX also use 4b11 engine as what lancer used. And proton did not allowed to touch engine, ecu and transmission.


And it is MIVEC engine, you can feel the car sudden power at a certain RPM.


Anyway, comment from owner is better than those who are assumed they do a 'good' research. and it is funny to see one commenter commented about MIVEC and CVT, bcoz both are a different thing.
