Based on the requirement that pax "

(But will this interim CAP 1145 requirement ever
actually be implemented?)
Interesting to note from their respective Tech Datas that the cabin volumes for the two aircraft are near identical: 424 cu. ft. (plus 82 cu. ft. baggage hold volume) for the 175, vs. 396 cu. ft. (plus 85 cu. ft. baggage volume) for the 189. It's going to be interesting to see how these compare to the 525: the Relentless
minisite used to show a cabin volume of 390 cu. ft. for the 525, but this figure has now disappeared, with Bell quoting only a baggage hold volume of 128 cu. ft. and an unspecified "best in class cabin volume." Perhaps Bell is reviewing its cabin dimensions to offer something better justifying the 'super medium' label? The 525's external dimensions certainly seem bigger.

Airbus Helicopters claimed "

six for LCI,
six more for NHV and
two for CHI Aviation, with
Pegaso also claimed to have converted two options to orders. So perhaps
64, assuming that the 16 additional orders weren't conversions of options included in the 48 figure, and assuming also no additional
unannounced orders.
By comparison, AgustaWestland claims
orders for approximately 130 AW189s, "including options and framework contracts."

Interesting question, totti. The CT7 has a 10+ year advantage in terms of baseline technology and a better growth path (to at least 2,638 shp), but engine thermodynamic performance tends to be better at the upper end of the power spectrum (i.e. the 'part power' SFC problem). Then there's the new-generation Turbomeca Ardiden, selected for the Chinese AC352 variant of the 175, which is claimed to offer a
"10 to 15 percent reduction in fuel consumption compared with current engines in this thrust class".
