Want to buy either a GLE450 or GLE53.
Like GLE450's quiet cabin and smooth ride, and also like acceleration & dynamic feeling which lead me to consider GLE53.
But I am not a fan of loud exhaust sound.
Since GLE450 & 53 use the same engine, I assume that GLE53 adjust the throttle etc. Will this make GLE53 generates more cabin noise than GLE450?

Too bad no nearby dealer has GLE53 to test drive right now. Any suggestion? Thanks.

There’s not enough difference to even notice inside the car. The 53 is just a tiny bit louder in a low gear at higher R’s but the engine noise is also. I only noticed because as part of my break-in procedure I try to raise the R’s by holding a lower gear for brief periods…don’t drive that way normally. The 450 & 53 are both very quiet. The GLE 53 feels more like a V8 than a 6 and the Electric Boost adds more pep and pulls harder passing than the 450. I was pleasantly surprised at the difference. If you go 53 consider the DE6 Dynamic Plus Pkg. The Active Sway Bars (ARC) and the larger 6 piston brakes are a great add, but spendy at $5200 when I purchased a little over a year ago.
