Cd,
The vehicle is a GM 4 door sedan with the standard (at the time) 3.8 V6 with the 4L60E trans and weights about 1600 kgs (3300 lbs approx)
No mods and factory a/c which gets used quite a bit especially now (Summer here) with temps around the 40 C mark (105 F) and a dark blue car with a dark grey interior.
City MPG sucks at around 11 ltrs / 100 kms ( 21.3 US mpg)
Highway is better at around 7.0 / 100 kms. ( 33.6 US mpg)
These are for unleaded 89 octane.
Running on LPG the figures are about 15% more fuel used.
Normal hwy speeds are 90 / km hr (55 Mph)
Cheers , Pete.
