What cars have add on diffusers?

Lamborghinis have this option just to point some out. Volvo C30 I believe also has one. I think it's almost any super car and most hatchbacks that get diffusers.
 
Viper GTS '02 - makes it look a little like the racing version if you add a wing and change the wheels as well!!
 
@ mark
How I would describe a diffuser. An aerodynamic aid used to clean the airflow underneath a car, wich can either be at the front or back. It increases downforce by making the air flow faster underneath, creating a difference in pressure, that sucks the car down. There. I think that's right.

Good ol google .. ;)
 
He's probably talking about something like this.

Yes I know what a diffuser is.

There are many cars with these in GT5, Abd you obviously did'nt do a search.

It's a hugely common misconception (thanks to several inept commentators and unsuccessful has-been drivers) that the diffuser is only the rear section, the diffuser is actually the whole floor/underside of the car, this is from the splitter all the way to the very rear of the diffuser. The reason we hear "rear diffuser" is because we tend to hear them talk in reference the rear part of the diffuser, mainly the tunnel sections which are actually called venturi tunnel(s).

I think you need to be clear on whether you mean tunnel section/rear diffuser in terms of something like this (the black carbon area petruding from under the car) :

Or a standard racing diffuser which is basically a smooth flat underbelly which conceals the petrusions which cause drag under a normal road car as well as producing low pressure.
 
The diffuser is only the rear section, where the cross sectional area begins to increase. The entire thing is called an undertray.

After recent testing, it seems that nothing but the rear wing adds to performance anyway, so GT5's diffusers (and splitters, and canards) might be useless.

Nope, the diffuser is the whole floor. Look it up in an aerophysics book and not wikipedia.

That was already done before I posted.

The entire undertray can be a diffuser, but only if it decelerates the flow. Usually, only the rear section does this.

Car makers and racecar manufacturers make use of the whole floor to do this, look at the floors for DTM and LMP cars.
 
It's also why race and some road cars also have rake...to improve undertray and diffuser performance.

Not really. LMP's have an undertray with a front and rear diffuser, DTM's like most touring/GT cars have only a rear diffuser behind their undertray.

The one I'm designing at the moment

The diffuser is driving the undertray by creating a low pressure region in the back and accelerating air ahead of it. It then raises the air pressure to lower drag, and directs the air upwards to generate downforce. It would be like those seen on GT1/2 cars, although this undertray is for an open wheeled car.

The diffusers in the middle are for the rear wheels.

Whats the point when only one form of diffuser is available in the game?
 
@ everyone, just to clarify, I am looking for a list of cars with ADD ON rear diffusers that can be purchased through gt auto.

Thats what I meant, I tend to mix up what I'm trying to say through funny wording at times, guessing you know Mr. Fuller too.
 
Okay guys, can we put the nerd glasses away and stop having a full blown argument about the exact meaning of "diffuser". We all know what he means: the little aerodynamic bit underneath the back of the car which can be fitted at GT Auto. Now can people actually help answer this question instead of having a stupid argument.

I think the Lamborghini's have them... I'm not sure about any other cars.
