Your last sentence is key - 99.999% of people don't buy a mid-sized family sedan for competitive racing. There will always be the curious outlier who takes their stock or modified Accord to the drag strip or autocross, but that's rare.Anyone know how the handling of the Sport or Touring compares to the EX? I have a 2018 EX and while it drives fine on a straightaway and slight bends.... if I drive it hard into a curve, the the front end dips like a bucking bronco - definitely doesn't corner very well.
For reference, my previous car was a 2014 Fusion SE and it handled way better. I also test drove the 2018 Camry XSE 4 cyl and thought it cornered a lot better as well.
All this said, I haven't really heard anyone else complaining about the EX's handling, but maybe that's cuz folks don't buy it for handling in the first place.
With that said, you don't necessarily have to participate in an autocross even to enjoy great handling which can inspire confidence and afford better handling in emergency situations - an extra 0.1 g of lateral grip might be just enough to swerve out of the path of a hazard.
The differences in performance between Accord trims are fractional at best. If you look at the results of Car and Driver instrumented tests, you'll see only very minor differences in noise levels and handling between the various trims that most people wouldn't notice without sequential A-B comparisons and test equipment to detect those minor differences.
The difference in performance between an Accord LX and an Accord Sport which has wider tires, bigger wheels, stiffer springs, stiffer stabilizer bars, larger front brake rotors, etc. is nowhere near as big as the difference between, say, a Civic LX and a Civic Type R (or even a Civic Si).
The Accord has weight and a family-friendly suspension working against it when it comes to handling - no matter which trim you choose. Simply put, no Accord is designed to take 90º turns at imprudent speeds.
Going back to instrumented testing, all (remaining) mainstream, mid-sized sedans are decent handlers for everyday driving these days. Very little separates the worst from the best.
