the rsx has no option for nav i was in the ordering process and when they told me the civic can get nav and the rsx can't i bugged. The high revs also costs gas don't forget that
All performance costs fuel. The new Si rates 23/32 and the RSX 23/32, which is pretty amazing given the performance. They are both faster than my 325i with manual.
Granted, my 325i is quite a bit heavier. Still, their performance to gas use is pretty good.
The GTI, as with many turbo's, can buck the trend a bit as they can give great performance while having seemingly great MPG. The GTI is a good 400lbs heavier than the Si and RSX and it's rated at about the same at 23/32. However, dip into the boost a bit too much and those numbers drop pretty big as with many turbo's. The nice thing about turbo's is that you can have small displacment economy when you're not asking for the power, but you can have the power when you ask for it.
So, boost costs MPG as big throttle high rpm can.
The problem with a lot of turbo engines is that they run too rich at big throttle high power moments, and that does cost in fuel.
I except the new RSX will be quite nice and be a closer match to the high quality interior of the GTI. The Si is an awesome low cost performer, but you can see where the money wasn't spent.
But, you get a sweet LSD for that lower cost. That's an item that VW should have put on their performance FWD car.
