Subaru Impreza WRX STI Automatic: Full Guide, History, Options & Buying Facts

Did Subaru Ever Make an Automatic WRX STI?

Many car enthusiasts search for “Subaru Impreza WRX STI Automatic”, but the truth is clear: Subaru never produced an official factory automatic WRX STI for any market worldwide. Every genuine STI model — from the early 2000s to the final 2021 generation — came equipped exclusively with a manual transmission, typically Subaru’s iconic 6-speed manual.

However, the interest in an automatic STI continues to grow because of:

Enthusiasts wanting STI performance with automatic convenience
Misleading listings or dealership descriptions
Aftermarket automatic transmission swaps
Confusion with the Subaru WRX automatic, which does exist

Even though a fully automatic STI has never been offered officially, there are legitimate ways drivers encounter “STI Automatic” models — and this article covers them all.

Why Subaru Never Released an Automatic STI

Subaru built the WRX STI as a rally-inspired performance model, prioritizing:

Driver engagement
Precision control
Manual gear selection
Mechanical connection to the drivetrain
High-performance AWD response

The STI’s 6-speed manual is engineered to handle high torque, aggressive launches, and rally dynamics that most automatics (especially pre-2018 models) could not reliably support.

Subaru engineers have stated repeatedly that the STI must remain manual-only to preserve its heritage and durability.

The Closest Alternatives to a Subaru WRX STI Automatic

Although no official automatic STI exists, drivers who want a similar experience have three main alternatives:

1. Subaru WRX Automatic (CVT or 4EAT Older Models)

The standard WRX, unlike the STI, has been available with automatic transmissions including:

Sport Lineartronic CVT (newer models)
4EAT automatic (older WRX generations)

These models offer:

Turbocharged power
Symmetrical AWD
Daily-friendly driving experience

But they are still not STIs — the STI has different engine tuning, gearbox, suspension, and performance hardware.

2. STI Automatic Swaps (Aftermarket Conversions)

Some performance shops modify STI models to run:

Subaru 5EAT high-torque automatic
Built racing automatics
Custom sequential-style transmissions

These conversions are expensive but possible for drivers with specific needs such as:

Drag racing
Disability accommodations
Daily-driving ease with STI power

3. Japanese Domestic Market (JDM) Special WRX Variants

Although Japan received many unique Subaru trims, none of them were true STI automatic models, but some came close, such as:

WRX S-GT automatic
WRX A-Line (turbocharged automatic models)

These are often mistaken for STI automatics due to similar styling.

Common Misunderstandings About “STI Automatic”

Searches for Subaru Impreza WRX STI Automatic often stem from confusion caused by:

Dealerships labeling a WRX CVT as an “STI appearance package”
Sellers using “STI” to describe cosmetic parts
Modified WRX models with STI badges
Auctions incorrectly naming JDM WRX A-Line variants
Aftermarket STI body kits on non-STI cars

When buying a used car labeled “STI Automatic,” it is essential to check:

VIN number
Transmission type
Engine code (EJ257 for STI)
Suspension and drivetrain hardware
STI-specific parts

Most “STI automatics” online are WRX models with cosmetic upgrades.

Should You Buy an STI Conversion or a WRX Automatic Instead?

Choosing the right option depends on your driving goals:

Buy a WRX Automatic If You Want:

Daily comfort
Turbocharged performance
Lower maintenance cost
Modern CVT convenience

Buy a Real STI (Manual) If You Want:

Full rally-style performance
Maximum tuning potential
True STI handling and AWD
Collector value

Consider an Automatic Swap If You Need:

STI power with automatic operation
Unique performance builds
Specialized driving accommodations

Swapped STI automatics can be incredibly fast but require:

Expert installation
Strong transmission builds
Higher maintenance costs

Conclusion

The Subaru Impreza WRX STI Automatic does not exist as a factory model. Every official STI ever produced is manual-only. However, drivers searching for an automatic STI can explore WRX automatic versions, JDM WRX A-Line models, or aftermarket STI automatic conversions. Understanding the differences ensures you’re not misled by inaccurate listings, modified cars, or mislabeled sales posts.
