According to the Italians and the Swiss, pretty good - as good as you can get with a FWD car, anyway.
YOu do realize all the changes that would have to be made to the Abarth to make it legal in the U.S.? Changes that would add significant amounts of weight and emissions changes that would destroy the HP.
I had a european spec RX-7 when I was in Germany. Had a friend that brought his american spec RX-7 over. I got almost 20% better gas mileage than he did, and my RX-7 would top 160MPH easily, his couldn’t even get past 120.
I checked into “americanizing” my car when I got my orders back to the states - was going to cost me over $5000 to changes all the frame stuff and add the emissions stuff. I sold the car instead of destroying it.
The Abarth will have a far higher price tag and far worse performance as a U.S. model. Plus it is one of the ugliest vehicles I think i have ever seen — it looks like a VW bug that didn’t finish cooking yet.
