The Piper Twin Comanche can fly at 160 kts on 50 litres per hour and carry 4 or even 6 people if you fly on reduced fuel load.
Performance is spot on. 4 or even 6 people? Dream on.
I'm in the south of Germany, having been conveyed there majestically in our beautiful Twin Com (the same one pictured in the Oct 2006 Flyer article). However, with just two of us plus baggage for a holiday, I wasn't able to load full fuel (had to leave out 12 USG, in fact). With 4 people, endurance is down to about 3 hours to dry tanks. With 6??
I wouldn't have a different aircraft, but it's not a regular 4-up ship.
