Lexus Models Naming System Decoded
Understanding how Lexus names their vehicles – a simple guide to their alphanumeric code system
What's in a Name?
Lexus vehicles follow a structured naming system that tells you a lot about the vehicle without seeing it. Think of it as a code where each part has a specific meaning.
For example, in RX 350h:
RX Tells us it’s a Radiant Crossover (medium-sized SUV)
350 Tells us about the engine size (3.5 liter)
h Means it’s a hybrid (uses electricity too!)
Why Automotive Naming Matters
Automobile manufacturers like Lexus use specific naming conventions to communicate important information about their vehicles in a consistent, efficient way.
Lexus uses an alphanumeric system where letters and numbers each carry specific meaning. Understanding this system allows you to quickly identify a vehicle’s class, size, and powertrain just from its model designation.
The First Two Letters = Vehicle Category
The first two letters in a Lexus name indicate the vehicle category and body style – similar to how clothing comes in different types for different purposes.
SUVs: UX, NX, RX, GX, LX
These range from compact to full-size luxury SUVs.Sedans: IS, ES, LS
From compact sports sedans to executive luxury models.Coupes: RC, LC
Performance-oriented luxury coupes.The Numbers = Engine Performance
The numbers in a Lexus name (like 300, 350, 500) indicate the engine’s displacement or performance level, giving you an idea of power without looking at specifications.
200-300 = Entry-Level Engines
Like IS 300: Typically 2.0-3.0L engines with balanced power and efficiency.
350-450 = Mid-Range Engines
Like RX 350: Usually 3.5L V6 engines offering stronger performance.
500+ = Premium Engines
Like LS 500: Top-tier powerplants with maximum performance and refinement.
Special Letters = Additional Features
Lexus sometimes adds suffix letters to their model names to indicate special features or capabilities.
“h” = Hybrid
Like RX 450h: Indicates a hybrid powertrain combining gasoline and electric power.
“F” = Performance
Like RC F: Designates high-performance variants with enhanced power and handling.
“AWD” = All-Wheel Drive
Like NX 350 AWD: Indicates power distribution to all four wheels for improved traction.
Putting It All Together
Now you can decode any Lexus model designation by understanding each component.
Example: RX 350h AWD
- RX =Radiant Crossover (mid-size SUV)
- 350 =3.5 liter engine (medium power range)
- h =Hybrid (gasoline-electric powertrain)
- AWD =All-Wheel Drive (power to all wheels)
So it’s a mid-size SUV with a medium-range hybrid powertrain and all-wheel drive capability.
