What Is a VB WRX? | Subaru’s Current-Generation Chassis Explained

If you keep seeing “VB WRX” online, it’s not a special trim or a new engine—it’s the internal factory code for the WRX’s body and platform generation. Subaru uses simple two-letter codes to mark each generation of its sports sedan, and VB replaces the previous VA code. Knowing this distinction matters if you are shopping for a used WRX, ordering parts, or just trying to follow an online discussion without getting lost in the jargon. This guide explains what the VB WRX is, how it differs from the earlier VA generation, and what powertrain and trims define it, using current U.S. market data.

VB vs. VA: The WRX Generations

The VB code applies to the 2022-and-newer WRX models. The previous generation (2015–2021) used the VA code. These are distinct platforms, so parts that fit a VA WRX—especially suspension, body panels, and interior components—often do not bolt onto a VB WRX. Subaru builds the VB on the Subaru Global Platform, which gave it a stiffer chassis and revised suspension geometry compared to its predecessor. If you want to confirm you are looking at a VB, check the model year; anything 2022 or later is a VB. Here is a quick comparison of the two generations:

The single most common mistake in the enthusiast community is assuming parts from a VA WRX will work on a VB WRX. Always check fitment by generation code before buying any performance or replacement part.

Engine and Performance of the VB WRX

Subaru pairs this engine with a standard six-speed manual transmission, and a continuously variable automatic (CVT) is optional. All models come with Subaru’s symmetrical all-wheel drive. For those looking to modify a VB WRX for more power or better handling, our recommended VB WRX parts list covers the most popular and tested upgrades. The current WRX is not offered in a full STI variant, but performance-oriented trims like the tS have stepped in to fill that role with enhanced chassis tuning.

VB WRX Trims and Pricing

The current U.S. lineup includes Base, Premium, Limited, GT, and the newly added tS trim. All trims share the same 2.4-liter engine. The main differentiators are the available transmission (manual vs. CVT), wheel and tire packages, interior materials, and additional driver-assistance hardware. Subaru’s U.S. documentation shows that the VB WRX has been available since the 2022 model year.

Frequently Asked Questions

Does the VB code affect insurance or registration?

Insurance and registration systems rarely use Subaru’s internal chassis codes. They rely on the Vehicle Identification Number and model year. You will not see “VB” on your insurance card or title, but enthusiasts use the code to precisely identify the vehicle generation for parts discussions.

Is the VB WRX the same as an STI?

No. Subaru discontinued the standalone WRX STI for the current generation. The VB WRX does not have a full STI variant with a different engine or drivetrain. The tS trim offers some handling upgrades but uses the same 2.4-liter engine and all-wheel drive system as other VB WRX models.

Will VA aftermarket parts fit a VB WRX?

Generally, no. The VA and VB WRX use different platforms, so suspension, exhaust, and body components are not interchangeable. Always verify fitment by selecting the correct generation code before purchasing aftermarket parts. Some interior items may share a similar design, but they rarely mount in the same way.
