I have posted this before but posting again to help you in choosing your variant in Corolla.
1.Altis 1.6 has alloys, nav ready infotainment system, Hi Grade fabric seats as mentioned on indus website (Please see),Extra two color Super White and Bronze Mica if you want to opt that and above all dual VVTI 1598cc bigger Engine. you can get after market alloys, infotainment system in the price range of 90k (125k-90k= 35k) but you cant replace 1.3 engine to 1.6 engine in 35k. Price difference between 1.3 Gli A/T and 1.6 Altis A/T is 125k.
2.It has dual VVTI engine as compared to Single VVTI engine in GLI A/T. As coated by our brother @ausbii
A. The engine on the 1.6 is not just bigger, it's newer and more efficient both in terms of fuel consumption and power output. NZ-FE(1.3)VVTI series vs ZR-FE(1.6)Dual VVTI.
B. The transmission on both is 4 speed super ECT but it's not the same. The 1.6 has an Aisin Warner (one of the worlds top transmission manufacturer) A341E original japanese transmission. The 1.3 has a toyota U341e which to the best of my Knowledge is from Thailand. The A341E is much smoother and more reliable. Also to consider is that the u341e is designed for 1.5l engines, not 1.3. It has a first gear ratio almost 1.5 times that of the first in manual gli and a second gear ratio equal to what would be a 2.75 gear of the manual while the third is equal to the fourth on the manual. That is why the 1.3 gli AT is significantly slow off the mark as compared to the gli manual. AT is always slightly slower than manual but the difference is quite significant here. The same specs go to the advantage of the 1.6 as the more powerful engine utilizes the lager gear ratios for a more rapid off the mark acceleration and even slightly better fuel economy than the competitions slower 5 speed with a 100cc smaller engine.
3.I do not believe that 1.3 Gli is an underpowered car . Many pakwheeler friends are satisfied with their power (you can see @fouadbakht bhai and @aliusman420 bhai thread . I didn't drive 1.3 Gli A/T 11 gen but i thing 1.6 drive will be more joyful as compared to 1.3 drive due to their gear ratio.
This is my opinion, hope it will help you in buying your car.
