Even though each Rocket League car doesn't state how different it is from another, there are enough subtle differences between a car's size to mean its hitbox could be radically different from another. Just because you can't see it, doesn't mean it isn't there.
And though many have likely thought of the possibility, the exclusion of car stats within the game might make others think less of the fact that one car might simply just be better than another - although only in a very specific situation.
For the most part, it shouldn't matter which car you choose in Rocket League. The differences are so minute, you likely won't notice much of a change in your performence. But if you've commited hundreds of hours into one car, you might notice your shots being a little off target, or your handbrake turns being a little slower than you remember. Just like any real car, switching to another takes a little readjustment.
Thinking of taking up the Rocket League farming mantle? You might want to read these Do's and Don'ts.
But going back all the way to March, you can crawl around the Rocket League subreddit and see some very passionate fans detailing these subtle differences. With the hitbox of the low-wheeled, aerodynamic batmobile certainly being more slimline when compared to the Merc van, you can expect the same to be true for the rest. Though recent patches have ironed out many of the differences in individual car turning radii, hitboxes still differ. You can download a handy Excel spreadsheet to do some research into your next main vehicle, or simply open it up in Google docs.
Of course, the work must be given credit. Virixai of the Rocket League subreddit has been provided the work for many months now. Go into the comments there to see some heated discussions, too. It's quite the eye-opener.
