The 380S was a physical high-performance Impreza proposal shown in Britain in 2008. Its name described a target for a potential Prodrive-developed road car, with final specification and customer response still unresolved in the contemporary announcement.

Use the documented 2008 show reference

The surviving contemporary announcement places 380S at the 2008 British motor show, correcting the workbook’s 2009 reference. A matched event photograph supports the physical display identity. This is important because the car should not be dismissed as a digital-only suggestion, yet it also should not be described as a completed numbered customer series. The most accurate reference is the particular concept and the proposal made at its public presentation.

The performance number was a development target

The reproduced manufacturer announcement describes a planned Prodrive engine rebuild intended to achieve 380 PS. It also says the final specification would depend on further input. Those are conditional statements, not a verified dynamometer result for the photographed display vehicle. A specification should therefore label the target clearly and avoid turning it into a certified power output, a guaranteed reliability claim or a count of planned or completed cars.

The hatchback provided a practical starting point

The proposal used the contemporary STI hatchback form. As design interpretation, its appeal was the possibility of combining a compact, useful body with a much more focused performance brief. That does not mean every modified GRB making similar power is a 380S. The name belongs to the documented proposal and actual show identity, while privately developed cars require their own provenance rather than borrowing a factory-related concept designation.

The proposed equipment did not freeze a final customer specification

The announcement mentions changes to suspension, exhaust, body treatment and wheel choices. Because the car remained a proposal in that source, those details should not be used as a final production parts catalogue. A component photographed on the display car might differ from an intended customer configuration. Preserve the date and context of each specification rather than combining tentative details from different reports into a supposedly definitive model.

The archive boundary is deliberately narrow

This profile records the physical 2008 concept and contemporary proposed programme. It does not claim a new independent proof of every later development outcome or repeat the workbook’s exact one-prototype count as a verified census. Keep exhibition photographs, source announcements and any later programme documents together. If an individual road car is claimed to be the show vehicle, that assertion needs a continuous chassis and ownership history beyond a resemblance to the original image.

Rarity and production scope

The cited announcement and matched photograph verify a physical 380S concept identity in 2008. They do not establish a completed customer run, a lifetime one-chassis census or a final certified specification. The 380 PS figure remains a development target. This Archive entry is excluded from completed road-production counting, and later modified Imprezas are not automatically members of the concept’s proposed programme.

This is an Archive identity. The experimental or individually named car is not added as extra production on top of its underlying family. Repeated exhibition appearances do not establish additional chassis; the specific scope above governs the count.

What the photograph represents

The physical 380S concept photographed at its British show presentation in 2008. The livery and event setting are preserved; the image does not prove a certified 380 PS result or completed customer production.

Frequently asked questions

Does 380S prove the display car produced 380 PS?

No. The contemporary text describes a target and a specification still subject to development.

Why is the workbook’s 2009 date changed?

The cited show announcement and event context document the physical proposal in 2008.

What is the production-count boundary for this profile?

The cited announcement and matched photograph verify a physical 380S concept identity in 2008. They do not establish a completed customer run, a lifetime one-chassis census or a final certified specification. The 380 PS figure remains a development target. This Archive entry is excluded from completed road-production counting, and later modified Imprezas are not automatically members of the concept’s proposed programme.
