That’s positioning and marketing too since you don’t really need the performance. For 99% of the time you use the car they’re about the same. If only life were all twisties and race tracks, but in reality it’s mostly traffic jams.
The Camry on the other hand is one of the least pleasing cars to drive. The suspension feels “floaty” and the steering wheel is completely dead. It also feels completely outdated and cheap and the UI is bad.
I think most of car ownership is Signalling personally
Things like handling, the interior quality, noise makes a big difference to some.
Would I replace my BMW with a Toyota if it handled as well, had as good engine, had a better screen and computer system and such a well calibrated gear box - of course. And Lexus IS getting close.
So I would prefer a Toyota that handles nice over a BMW, but it would not be a Toyota. Toyota optimizes their cars for reliability and cost whereas BMW optimizes its cars for high performance and comfort. Specifically, their cars, like other German brands, are well suited for safe high-speed cruising on the autobahn, making them incredibly solid driving machines.
But the true enthusiasts don't care much for signalling or Brands but prefer the visual styling and the capabilities of the car.
Market segmentation at work.
Even if this is the case, you're better off with an econobox daily driver and a second specialy fitted track car with the correct safety equipment (5 point harness, Hans device, roll cage, fire suppression).
