I recently had my C6 (base coupe) aligned front and rear. Today on the highway I noticed it wanting to drift to the right. Is this normal? I recall reading once that for safety reasons a bit of right-drift is built in, but never was able to confirm that.

Check the brakes and tires - then re-align

No. Should track straight on a level road.

take it back. Make sure the road is flat. No crown on it when you test it..

I have never done alignment on any of my cars (and I keep them at least ten years) and I can drive them with no hands!

Check tires psi...sound's silly but you would be surprised how many shops do a 4 wheel alignment and don't!

Not So Fast

I find that my 2011 GS does drift right or left as the road dictates, sometimes tracks straight. It is my opinion that especially with the wide tires on the GS that they will follow any abnormalities in the road surface. Crowns, slopes, grooves, joins etc. plus also have been informed of the "Trammel" effect which I don't really know too much about. I check tire wear constantly and all seems good.
So I'm leaving it alone

Mine will follow the crown in the road but on a flat road it will track straight as an arrow

Your profile only says you are a male, so with no info where you live doesn't help.
If you live where it rains a lot and/or occasionally has snow, then roads are crowned more than drier areas. A good alignment guy will compensate for that, but an average one won't and it'll drift to the right.

If you have a 3 lane divided hwy nearby, drive a couple miles each direction in the center lane. The results will tell you if the alignment is set for flat roads or crowned. Also fill the tank to equalize fuel weight and make sure tire pressure is the same on all 4 tires.

Houston, and indeed I tried all three lanes on a couple of Interstate highways. Tank had just been filled. Tires are all good at 8/32+. However, once home I did check air pressures to find the left side a bit lower than the right. I'm going to test it again and if not improved head back to the shop.

Thanks for all the input.

Low tire pressure on the left would cause a drift to the left, more drag/increased rolling resistance.

My DD 11 CTS has 31K on it. Never been aligned, wheels are balanced and have never rotated the evenly worn tires. Same on my last one. Unless you see uneven wear or steering issues why mess with the alignment? Same goes for balancing and rotation. I know that it is all dependent on how/where you drive but just because a certain amount of time and/or miles have passed does not always call for messing with things if they are fine. Was it drifting before? What was the reason for alignment? My car is going to be nine years old January 2nd. Nothing done with tires/wheels except for the alignment check after the oil pan gasket replacement.
