Wow, thats a horrible taste in your mouth! No way!

I've gone on a long road trip with the 86 900 SPG and the 96 9000 Aero. True to their advertised mileage, they were/are very efficient. I have to do some story telling now...

86 900 SPG (acronym for the top model variant) has a 2.0 turbo engine that made 170hp and ~195 ft. lb. (264.38 Nm) of torque, when it was new in '86 :P Those are pretty decent performance numbers, especially back in its day.
I drove the 86 900 SPG about 2,500 miles (4,000 km) two summers ago, down the west coast (all main freeway) of USA, a week of city driving in southern california, then a drive up the west coast (scenic coastal freeway), probably averaged 75 mph, with A/C on... total calculated mileage was 30.2 MPG ( 7.79 L/100km) To be fair though, this specific car 'only' has 160,000 miles on it.

96 9000 Aero (top model variant) has a 2.3 turbo engine that made 225hp, and 258 ft lb (350 Nm) of torque, when it was new and stock in '96 :P. Again, decent power. It makes more than that when I drove it for a long drive last summer. I think the total mileage was 1,800 miles (2900 km) on the road trip. Average cruising speed was ~80 mph. There was a week of driving around Colorado (large elevation changes, 0 to 10,000 feet elevation). At the end of the trip, average fuel consumption was at somewhere between 31mpg and 32mpg (7.47 L/100km).

These mileage numbers are considered quite impressive in the USA auto market and for the power these engines make, especially for 'old technology, inefficient designs' or whatever people are supposed to believe here...

(cruising on flat-ish freeway a few hours after a gas station, thats why the display says 33.3 mpg, although it turned out to be pretty close to my manual calculations throughout the trip)

Sorry to those who don't care about long stories of fuel consumption.
I couldn't let a neighbor of Sweden think such poor things about the classic SAAB 900
