Most of us have Cars to test and prove. Pakwheels reviews are nothing special either. Grande gave better mileage vs Oriel 1.8 .. I agree I kept grande for a good 3.5 yrs.
Against turbo, no match. The main thing is it's so hard to drive turbo without enjoying it and that's where u get mileage hit. When I drive normally in heavy traffic and with family mileage is over 12 tan to tank but when I find an empty road and drive alone, mileage drops to even 10 for me....Again tank to tank ...meter mileage is not accurate. Turbo has the best balance in terms of economy and drive.
Munj sb alone cannot explain anything...and best experience comes from individual experiences as all cars are driven by different people and average can be idenitified.
