Hi, I'm looking at buying an Audi A4 possibly SE with c/control.
I've heard that on most newer cars these days the aircon doesn't affect the fuel consumption as much. Is this true on the Audi A4? I was looking for a '97 - '00 A4.
Also, can someone briefly describe the differences the various models of A4 eg SE/T etc.
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 engine.
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.
