There have been several comments about turbocharged engines being different internally with heavier rods, bearing and other parts. That may be generally true, I don't know.
fwiw During the mid to late 1990's, the turbocharged 5 cyl Volvo engine was mostly the same as the NA engine. Internally the only parts that I can remember being different were the piston (for lower compression of course) and the sodium filled exhaust valve. As for the transmissions and gearing - I have no idea if they were different.
I can tell you that I've been very happy with the mpg of my turbo car. My Saab 9-5 turbo has averaged about 32mpg over the last 13,000 miles. The odometer is showing just over 205,000 miles. As the OP and others have pointed out though, I have nothing to compare it to that would be a fair comparison.
