>>1454534>>1454545You have no idea how absurd Piaggio Avanti is, the specs in Wikipedia are:
Beechcraft Starship:
1 or 2 crew, 6 passengers
Empty weight: 10085 lb, 4574 kg
2 × PT6A-67A 1200 shp (890 kW) each

2 × PT6A-66B 850 shp (630 kW) each

(it's 348-397 mph in this link:

Range: 2800 km, 1740 mi, 1510 nmi
It has much better specs despite the 40% decrease in power on both turboprops.
Still a modern single engine turboprop is very close:
Pilatus PC-12NG:
1 or 2 crew, 6 to 9 passengers
Empty weight: 6,195 lb, 2,810 kg
1 × PT6A-67P 890 kW (1,200 shp)

Range: 3417 km, 2123 mi or 1845 nmi
