2019 Subaru WRX STI S209
Explore the Subaru WRX STI S209: history, verified identity, specification references, rarity evidence and real credited photos.
The S209 brought STI’s S-series complete-car approach officially to the United States with a 209-car programme. Its wide body, 341 hp 2.5-litre boxer and coordinated chassis and aerodynamic changes distinguish it from a regular WRX STI carrying selected accessories.
The first official US S-series programme
STI’s heritage account identifies S209 as the first S-series model for the American market. The 2019 programme follows Japanese S-series complete cars but has its own engine, dimensions and market specification. Its number is part of the model name as well as the stated 209-car production reference. A reliable history should preserve that American identity rather than assuming that specifications from S207 or S208 automatically carry across to this wider-bodied car.
STI: S209 US programme and specifications
The 2.5-litre engine has an American output reference
The factory table gives an EJ25 of 2,457 cc, with 341 hp at 6,400 rpm and 330 lb-ft at 3,600 rpm. The US units are retained rather than silently relabelled as Japanese PS. The six-speed manual and AWD complete the drivetrain reference. These figures explain the original specification; they are not a claim about the measured output of every surviving example after maintenance, software changes or mechanical modification.
The wide body is linked to chassis equipment
STI lists 19-by-9-inch BBS wheels and 265/35 R19 tyres within the S209 specification. The expanded bodywork gives those components a different relationship with the standard sedan’s silhouette. As design and engineering interpretation, the wider stance makes the complete-car character visible before the badges are read. Authentication still needs chassis and factory records, because individual panels, wheels and exterior details can be installed on a different underlying WRX STI.

Aerodynamic and cooling features should be described precisely
The heritage presentation identifies carbon roof and wing elements and the model’s cooling-related equipment, including an intercooler water-spray system. Those details belong to a coordinated specification. They do not independently establish a particular lap time, downforce value or present mechanical condition. Detailed photographs and service records help distinguish original equipment from later replacements, especially where a car has been used on track or changed for a particular owner’s preferences.

The show image is an edition reference, not a chassis census
The included Chicago show photograph explicitly identifies S209 and records the rear treatment and displayed model name. It is useful evidence of the programme’s public presentation, with the original photographer and image licence retained. A collector file for a customer car should add original sales material, VIN-linked documentation and service history. Repeated display photographs and duplicated sale advertisements must not be treated as additional completed cars or independent proof of the whole programme count.

Rarity and production scope
STI records the US S209 programme at 209 cars. The number is retained as an attributed manufacturer programme reference, with no independent completion ledger or survivor register claimed. Other S-series models and modified ordinary WRX STI cars are separate identities, not additions to this allocation. The Chicago display photograph illustrates the named model and its public presentation; it does not establish the delivery or present condition of any particular customer car.
What the photograph represents
WRX STI S209 displayed at the Chicago Auto Show in February 2019. The rear view includes the S209 display identity and illustrates its body and wing presentation. It is a show reference rather than a customer-chassis delivery record.

Frequently asked questions
Was S209 officially intended for the United States?
Yes. STI describes it as the first S-series model for that market.
Can S208 engine figures be used for S209?
No. The US S209 has its own 2.5-litre EJ25 specification and factory output references.
What is the production-count boundary for this profile?
STI records the US S209 programme at 209 cars. The number is retained as an attributed manufacturer programme reference, with no independent completion ledger or survivor register claimed. Other S-series models and modified ordinary WRX STI cars are separate identities, not additions to this allocation. The Chicago display photograph illustrates the named model and its public presentation; it does not establish the delivery or present condition of any particular customer car.
