Sooo... we have two generations of older
Cascadia (2007 and 2013), and three of new one (2018, 2021 and 2024). Every step of this evolution is pretty minor, which is no wonder if there are so little time between the updates — seems like the next update will be around 2027-2028

.
On today’s stream, there were some explanations about the desicions made in the tuning options list — for example, those 10- and 13-speed
Eaton gearboxes are out of service, the sun visors are becoming less legal, and there are no need to make the sideskirts longer than a truck’s sleeper.
The most prominent change is the truck’s bumper and the headlights — the truck’s face now looks even more round than before and the percentage of chrome in the front grille is greatly reduced. Also, there were some changes in small plastic detaiils like the mudguard mounts. The «old» mirrors are not removable yet, so, with cameras and hood mirrors, you can make your truck uhm... mirrored to the teeth!

Obviously, the new truck model shares all internal parts with the previous generation — the fuel tank size is tied to the chassis type, the only change in the interior are electric handbrake buttons (wow, that’s serious!

Those two mushroom-shaped handles were used for several decades), also, the side camera mirror display will be installed in the middle of windshield. If not the licensed powertrain options and that liiitle difference in the wheelbase, I think the newer generation parts could be made as a set of tuning options, like it was made with
Renault T Evolution, when this update was presented for
ETS.
The engine lineup is now smaller, and not every gearbox has an optional retarder, also, say goodbye to vertical exhaust pipes. Finally, we have a new engine sound, different from older
Cascadia and both
WS models.
So, even if there are fewer options and less powerful top engine, I like the update — the fresh model looks more smooth and must be more efficient. But, if more round and round shape of the new aero trucks is not for you, there still is
WS 57X (like
my working truck from a previous garage

. BTW, look at its bumper — apparently, this shape was tested there before being applied for
Cascadia), and... new
Kenworth T680, with its own way of looking cool
