Maybe some SR22 operators can report their figures.
Just a datapoint of my SR22 G3 FIKI Perspective, without AC: Payload is 470 kg with a maximum of 92 USG fuel.
So if you only take 70 USG with you, you will have 280 kg left for people and luggage.
I don’t know if G1/G2’s have a lower empty weight.
I used to fly a Cirrus SR22T G5 with AC and these were its numbers:
BEM: 1116 kg
MTOW: 1634
Max fuel: 92 gallons (348 liters)
The G5 has 100 lbs more MTOW than the G3 if I remember correctly.
Most TB20GTs are about 900kg empty, so you can work out the payload with fuel.
Is the SR22 really 20kt faster, on best economy? Quite likely the T, at FL200+, with an oxygen mask 
Otherwise, what is the fuel flow to get 170kt TAS at say FL100? The TB20 will do 150-155 TAS at FL100 on about 10.5 USG/hr, and will go a bit faster with more juice going in.
The right comparison, with no TAS / FL ambiguity, is low level IAS which on the TB20 is 138kt at 11.7 USG/hr, at say 2000ft. That is slightly LOP.
G2 MTOW 3400lbs
G5 MTOW 3600lbs
Approximate (lowlevel) G2 fuelflow 160TAS 14, 170TAS 15.
I usually fly 170@10k@13GPH. Or 170k@14k@12GPH.
LOP of course.
Today, SR22 non turbo, 2800’, 70% power gave 170tas at just over 13.5 gal/hr.
At 10k I plan at 170tas and ff just over 12 gal/hr LOP.
The TB20 main spar
I was considering the same options back in 2016 and found a great Cirrus SR22 G2 NA (might even have aopreciated in value since). Fantastic traveling machine for the whole family. And as Jason said, backed up by an active factory as well as a really great type club (COPA). I get similar performance like Boscoromantico…
IMHO “Full Fuel Payload” is at best a convenience factor but never a performance figure.
If we had – just as thought experiment – the option of buying two planes of the very same type with exactly the same performance data, price, etc., but one of them had a 40 gal tank and the other had a 80 gal tank, it would be quite obvious that we always chose the 80 gal version – even though it had a about 110 kg less full fuel payload.
500NM range payload is a much better figure to compare performance…
Any Commander 114 pilots/owners here? What are typical empty/useful loads?
