There's some interesting stuff listed in there. Specifically, if the spec on the Fiat USA website is the most up to date for the current 500's then it looks like the redline for the Abarth may be just a bit lower than the base 500;s (6500 vs 6900rpm).
Additionally it looks like the listed compression ration for the Abarth is 9.8 vs 10.8 for the 500, and the Drag coefficient is 0.367 vs 0.35, but the electrical system is increased from 105 Amps (on the 500) to 140 on the Abarth.
It also looks like overall weight has gone up a bit (which I guess is to be expected (from about 2363lb to 2533lb).
One thing that is a little confusing though is that although it looks like the listed front row volume has gone up from 43.8 cu ft to 45.3 cu ft, total interior volume looks to have dropped just fraction (from 85.1 cu ft to 84.9 cu ft).
Another thing that's interesting to me is that the turn radius really seems to have climbed from 30.6ft to 37.6ft, and there appears to be some other changes in the overall steering (with the overall steering ratio dropping from 16.3:1 to 15.5:1 and the number of turns of the steering wheel from lock to lock going from 3.0 to 2.3).
Interestingly the front brake rotor appears to be 1in bigger but the back rotors appear to be the same size, with the calipers and swept areas both being listed as the same size as the base 500.
Now I'm really interested in seeing the MSRP tomorrow.
Thanks again for the link.
