Youtube is awash with reviews and impressions including a lap of the Nurburgring. 8 minutes 40, thereabouts without cracking a sweat. Not that I'd be intending to drive it like that, but I suspect it would look great with vintage bikes on top.
In the past we have had Alfa's for decades. From what I can see this would slay any Alfa we previously owned, and only need to see a workshop for annual servicing. And while some reviewers are talking about the plastics in the interior, lets not forget this is a small car with enough space to be practical, light, quick and not the price of a BMW either.
We will have them later in the year and I'm looking forward to getting acquainted. I still have one i30, it's likely to last forever and will be a shame to part with it. But maybe the i20N is a worthy successor. Certainly its got me thinking.
