well

since I have the GX model and I can tell you everything you want about it.
it 2.0L SOHC (( N/A of course )) with 125hp @ 5600 rpm.
5 speed M/T with AWD system and 15" wheels.
0 to 60 is just about 9.3 sec, and its top speed is 133 mph, stock !! (( this is the maximum speed I did on it and it can't go for more )).
when you look at it you will see no different between the GX and the RS.
here is a pic of mine
