Hey plebs, I've never driven a petrol car before and I'm wondering roughly what RPM they should sit at while cruising in top gear at 70mph?
I appreciate this varies wildly as a result of gearing, aerodynamics, wheel size etc. but I'm going to buy a petrol car with a 4 speed automatic, and having only owned 6 speed manual diesels I'm slightly concerned it will scream while cruising. My current car sits at exactly 2000rpm at 70mph and it's pretty great for cruising as the turbo comes on at 1800rpm so you can overtake without dropping gears and it's extremely fuel efficient.
I looked up the gear ratios on the car I'm looking to buy and in theory it has a higher top gear than any car I've ever owned, but obviously this doesn't say much as a petrol revs way higher than a diesel.
What's an acceptable cruising RPM in your opinion?
Thanks to be quite honest and fair.

Around 6k, 8k if uphill or against wind and should try to rev up to 10k before even trying to overtake anyone

It depends entirely on gearing and engine size. A Honda with a 4-speed auto might be doing 3500+ RPM at 70mph while a Crown Victoria with the 4R70 slushbox would be doing 1800 or less.

My old integra GSR was revving at 3k rpm while going ~90 km/h. Engine redlines at 8100rpm
Current G35 is revving at 3k rpm while going ~130km/h. Redline of 7k rpm
Top gear for both vehicles

Cruising at anything higher than 3000rpm isn't cruising, it's ear rape.

I have literally never had a car that revs higher than 2.5k~ while cruising at 60mph in top gear. 2005 Altima, 2012 mazda3, 2010 highlander, 2015 Lexus CT200h

My 2005 Mazda 6 s at around 3500 at 75 mph, which is about the limit of what's tolerable.
