That gauge looks awesome.
As far as Arduino control goes, not gonna happen. The Arduino features easy-to-use functions and therefore each call has a TON of overhead. I'm sure that changing a port is about 30 - 50 instructions (I know because I took ideas from some of the source). There's no way it would be able to process all the inputs and display gauges accurately, you'd get similar resolution to the OBD in the first place! You'd need something more custom than that.
Also, I looked into it a bit... turns out that driving VGA from a PIC isn't too bad on the processor. If you got something going at 48MHz you would be fine but no animations. If you had a separate chip drive the LCD you'd be perfect for this.
That is awesome. those are nice as hell. There is just to much to do to get this to work!

why not just use the arduino (atmega) to read the info from the dash pins? then relay that to the pc? let the pc handle the display.
and there are pic's that are faster but now we are getting pretty deep into hardward/software stuff beyond the average user.

I am an experienced driver (even with a racing permit lol), and there is simply to much information crowded down in the same space.
As I can see out of the picture, you have these moving parts:
1. Floating compass.
2. RPM gauge
3. Speed gauge
4. MPG gauge
5. Gear indicator (not moving but still changing quite often).
Underneath all of this, you even have a summary of the above items.
A combo of MPH and KMH is greath, but should rather be an option to change between, than displaying both at the same time.. Again because of it steals information.

My "perfect" smart gauge would do this:
1. While driving normaly, dispay speed with large digits in the middle and RPM gauge outside of the digits.
2. While driving fast, or in "race mode". Only display a large RPM unit, with a shift light. Nothing else. The RPM scale should be so that the needle on the scale should be pointing upwards when it's in the optimal power range.
Bad picture to use as an sample, but. http://www.dablyk.com/_photos/ogp7/images/img_0079.jpg
