There is a difference in 1300 & 1800 engine. Difference of 500cc means 500cc more power than 1300cc in same body. For details specs what u get more in Altis and what u dont in GLi can be found on Toyota website. Link given below.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com<o:p></o:p>
Now let me talk about my experience.<o:p></o:p>
In Local drive altis and GLi given same fuel average. 9/10 KM per liter<o:p></o:p>
On motorway altis and GLi given same fuel average 14.5 KM per liter @ 120 KM speed but if you reduce your speed @ 100 KM then ALTIS average is 15.7 KM and GLi average is 14.8 Km to 15 KM per liter.<o:p></o:p>
Despite of fuel average I found GLi is under power especially in mountain area even you can compare its performance on motorway at salt range area. Altis can easily climb @ 4th gear without any trouble with Ac no gear shift required. But for GLi sometimes you need to go down to 2nd gear to maintain speed.<o:p></o:p>
I visited Shogran in March 10 and my brand new GLi is hardly climb in 1 gear sometimes I need to switch off the AC but in June 10 again I visit to Shogran on ALTIS its easily climb in 2nd gear with AC.<o:p></o:p>
ALTIS is equipped with AIR BAG, Optitron Meter, Reading Lights, Wooden Panels, Alloy rims, Side Skirts, Colored mud flaps & door handles, Door moldings, 2 Extra speakers etc.
