I have to say coming from a Mazda RX8(230) to a Type R GT I am really enjoying the extra fuel economy of the R.
Driving the RX8 with a mix of economy and fun driving you where lucky to get 20mpg!
With the R the same economy and fun driving i am getting about 30mpg!
If you keep the V-TEC light on for long periods your fuel consumption drops to low 20s, (boy what a sound it makes when that light comes on

)
I do think the RX8 was a bit faster, but my Type R has only done 720miles so it should still free off a bit!
