Why is the 12th-generation Crown called 184?

Because the full name of the 12th-generation Crown is Toyota Crown GRS184. Below are the relevant details about the Toyota Crown GRS184: Powertrain: The GRS184 is equipped with Toyota's 2GR-FSE engine, delivering a maximum power of 309 horsepower and a maximum torque of 377 Nm. The domestically produced Crown engines come in three variants: 2.5L, 3.0L, and 4.3L. The first two feature a V6 cylinder 24-valve design, while the 4.3L engine is a V-type eight-cylinder. All are configured with the Dual VVT-i (Variable Valve Timing-intelligent) system for bidirectional intelligent timing variation of intake and exhaust valves. Interior: The classic black interior is equipped with a Mark Levinson audio system. The central console features air vents with sweeping airflow functionality.

The name Crown 184 is actually closely related to its chassis code. Having repaired Toyota vehicles for twenty years, I've seen countless old Crowns. This generation uses the GRS18 series chassis, where the first two digits combined with the drive type code form the 184. The rear-wheel-drive version, GRS180, was the early model. After the minor facelift in 2005, the drive number changed from 0 to 4, eventually becoming the familiar GRS184. This number appears everywhere in repair manuals and parts systems, even the tenth letter in the VIN changes accordingly. Most later models on the road carry the 184 code. Back in the day, master technicians at 4S dealerships loved calling it that during training, and now in car enthusiast circles, mentioning 184 immediately identifies it as the later model Crown.

Veteran car enthusiasts are well aware that '184' is the abbreviated chassis code for the 12th-generation Crown. To be more specific, GRS180 refers to the early version, but when Toyota facelifted the model in 2005, they upgraded the drivetrain system, and the code changed to GRS184. You can find this alphanumeric sequence printed on the trunk or chassis nameplate. This code encapsulates both the drivetrain configuration and chassis structure—mechanics rely on it when sourcing parts. Even in the used car market today, '184' is used to distinguish the 2005-2008 models. Details like headlight design and transmission programming align with this code. A true expert on this car can spot an authentic 184 version just by glancing at the taillights.

184 is the general term for the mid-cycle facelift of the 12th-generation Crown. Toyota's factory assigned codes to vehicles with different drive forms: the four-wheel-drive version is called GRS182, the early rear-wheel-drive version is GRS180, and the upgraded rear-wheel-drive version after 2005 is directly named GRS184. You can verify this by checking the chassis or the vehicle's green book. Many newcomers mistakenly think 184 is a model name, but it's actually an abbreviation of the chassis code. In the enthusiast community, calling it this way is particularly convenient—when someone mentions 184, everyone knows it refers to the later version with silver trim on the steering wheel, distinguishing it from the earlier version with a wood-grain steering wheel.
