Why does AM reception vary so much from car to car?

I have an old Explorer and get better AM reception than in a new Lexus.
What can one do? Also, it seems electrical lines cause lots of
problems. I try and listen to a small station Radio Sandy Springs 1620
AM in Sandy Springs, GA and some place I get great reception in other
places lots of static. Again, what can a person do?

What you can do is buy a car radio with a decent AM section. Sadly, most
car radios have AM added as an afterthought and the performance is poor.

Electrical lines will cause problems, but a better receiver with good IF
filtering will have less trouble than a cheaper radio with sloppy filters.

New AM radios just aren't as good. And all the electronic equipment in
newer cars (and those around you) doesn't help the interference problem
either.

Just as an experiment try to listen to the AM in your Lexus with the motor
off and see if the interference clears.

That depends on the quality of the radio in the car, the type of antenna,
and how good the connections were made. Several years ago some auto
manufacturers got rid of the whip antenna and replaced it with embedded
wires in the windshield. The results were poor distant radio reception,
varying also on the direction the car was traveling with respect to the
location of the station's transmitter.

And the radios in Lexus vehicles are among the very worst I've ever
encountered, at least in terms of AM performance. After hearing the
radio in a Lexus GS, I bought a Lincoln LS. The radio sounds fine,
even has AM stereo (not that it matters any more) and the car has all
the same features, more power, and cost less. So how much money did
Lexus save putting that cheap POS radio in the car I test-drove?

The only AM section I've heard that was as bad was in a Hyundai, and
in a Hyundai you don't expect better.

Hi Group!

I realize this is an old question, but I have not had access to the group
for a while.

The question is assumed the vehicles are operated in and arould the same
locale.

The short answer: the antenna. Change the antenna on the car and the
reception should improve.

The long answer: quality of the radio, antenna, and noise generated from
ignition system, other electronics inside the car,

Just because you payed for a better car does not mean that they cared about
AM reception any more than the less costly model.
