I remember watching that episode so I researched it and it turns out it's the 1.2 version (post April 2014). There's this article confirming it and a few comments from people on that article are saying get the twin air as it flies up hills. So that's good news.
You would think the 0.9 would struggle compared to the 1.2, but the stand 1.2 is 69bhp and the 0.9 is 105bhp. The ironic thing is the twin air is road tax exempt as it's meant to be more efficient, whereas it's not.
Ps: Good to see another Ipswich fan on here
Come on boro!!!
That is very odd as my KA shares the same 1.2 from the 500 and goes up hills fine lol. Also my KA is tax exempt too and yet you say the fiat isn't?
