Salam, i just stumbled upon this thread and read many of you are curios about knowing Altis 1.6 I have been driving this car for over 2 months now with my reading almost 4500km. Anyways currently my mileage meter read 11.5km/l with stock tyres obviously and couple of trip from Pindi to Lahore via GT Road and Motorway. Now I can only compare my car with Honda City Steermatic 1500cc (previously owned it for over 7 years). The throttle response is slower compared to City but over acceleration is on par with my old ride. Since the gear shifting ratio is quite high you only feel the response at over 3/3.5 rpm below.
Car ride, personally i feel Altis is TOO HIGH for me its like 2 to 3 inches high from the sweet spot and because of this height while driving alone on motorway you can easily feel air friction on the floor of the car compared to having 3-4 passengers and a trunk load of luggage that air friction noise was totally gone even the ride felt better.
Last week got my fog lamps installed with HIDs and Taiwanese Body Kit (the one they install in Thailand Altis Esport Model) without the trunk lid. I have attached some images for your reference.
Feel free to ask questions.
