73 Ford Gran Torino(weighed about 4100 lbs) was the quietest mid sized car tested. Rating: Quiet.

Noise levels measured in sones: smooth road at 30 mph: 18
rough road at 30 mph: 24
highway at 60 mph: 30
highway at 70 mph: 37


73 Chrysler New Yorker(weighed just over 4700 lbs) rated : Fairly quiet

Noise levels measured in sones: smooth road at 30: 18
rough road at 30: 26
highway at 60: 30
highway at 70: 34


except for the rough road difference in which the luxury Chrysler was noisier than the mid sized Ford, all other measurements were virtually identical

Could the rough road difference have been the reason why CR's rated the New Yorker only Fairly quiet compared to the Torino? Do you think there is a big difference between a 24 and a 26 on a rough road? Do you think in real life(like someone testing the cars outside the showroom) anyone would notice the difference in noise?

there isnt much difference between the cars, the torino had more wind noise at speed, but likely the new yorker had an irritating thumping sound that made the difference, along with a few extra rattles the torino did not have. the quality control at chrysler in those years was similar to AMC, very spotty at best.

Default what causes rattles?

what are the main sources of a rattle? what did GM and Ford engineers do differently than Chrysler to ensure those quiet ratings the Mopars missed?

whatever it was, they must have learned something because by 76, those cars were riding quiet

Yeah, Ford was far superior to Mopar in the early-mid 70s in this area.

Probably the quality of the interior materials, build quality, etc. This was the time when Ford was cranking out very well made cars in their mid-size and full-size cars. Quality control was their goal. Note how the doors on a 73 Gran Torino sound when shutting when compared to a 73 Satellite and how the panels line up more evenly on the Ford.

I dont know if it was the overall build quality by 76 that made the Mopars quieter than years before or not.. most of those same body styles in 76 were originally from the early 70s (on the mid-size cars) and the doors still seem to clang shut, etc. It could have possibly been where they simply started adding more sound insulation, but then maybe they did actually improve on quality control. Not sure. However, I know that the BIG Mopars (like the Fury, Monaco, New Yorker) starting in '74 was a complete redesign, so they probably did improve on overall quality by then.

Quick look at a 74 Monaco Brougham... isnt that nice?! These almost reminded me of the 74 Buick LeSabre...



and a 74 Fury Gran Coupe and Gran Sedan



1974 Chrysler New Yorker Brougham
