Climate uses a bit more fuel, specially on these hot days, I would say on my
2.6 quattro I get 27mpg on the motorway with the aircon on, Off I get 30
Town driving hits the fuel economy hard with the Aircon on.
But its nothing to worry about, the comfort factor is worth the extra MPG
for me, and if you dont like it, turn it off..
SE spec is normally electric rear windows, better seats, maybe a leather
steering wheel and gear knob.

1.8T's are quite basic, no electric rear windows, few come with Climate, but
again can be spec'd up.
If your in the states, almost all cars come with Aircon anyway, in UK its a
The smaller/weaker the engine, the more noticeable the effect of A/C on fuel
consumption. And not just fuel consumption, but decrease in power as well
(slower acceleration). I notice it on my '01 1.8T and I've noticed it on
all 4-cylinder cars with A/C I've driven ('91 Stanza 2.4, '97 Vectra 1.6,
'99 Primera 2.0). So far, the only car on which the A/C did not seem to
have any effect (gas mileage and performance) was an Accord with a 3.0 V6
In my 1.8T A4, I observe about 1 to 2 mpg increase in fuel consumption when
operated with A/C. I don't know if this is much or not.
