Independent vehicle research · global scope
An aircraft company built the first Subaru. A rally program built the WRX. A dog-loving, mountain-state owner base built the reputation. SubaruFacts follows the evidence across every era, every market, and both halves of Subaru's split personality.
Vehicle families
A kei car is not a WRX. A Baja is not a Tribeca. An Outback isn't just a raised Legacy anymore, even though it started as one. The catalog keeps every boundary and every chassis code visible.
Japan's first mass-produced kei car and the small-displacement lineage that followed it — the 360, R-2, Rex, Sambar, Vivio, and Pleo — almost entirely a JDM story, with the 360's brief and famously rocky US import chapter as the exception.
Subaru's first "world car" mid-size sedan/wagon, the platform STI's very first prepared car (the Legacy RS-RA) was built on, and the vehicle behind Subaru's 1989 Arizona endurance speed record.
Began as a raised, cladded Legacy wagon trim before becoming its own model line — a genuine "crossover before crossovers" story Subaru itself has credited with helping save the company during a difficult early-1990s stretch.
Subaru's rally-homologated performance icon, built to satisfy World Rally Championship Group A/N rules, and the single family with the deepest JDM-vs-US divergence in the whole marque — from the WRX/STI US introduction gap to a long list of JDM-only limited editions like the 22B.
A taller, more car-like AWD wagon launched before "crossover" was an established category — a genuine early-mover story, plus the SG-generation turbo XT and the JDM-only Forester STi.
An Impreza-based lifted crossover that became Subaru's entry-level adventure vehicle, with a brief transitional "XV Crosstrek" US badge before "XV" was dropped for MY2016.

1953 → present
Fuji Heavy Industries, a GM stake, a Toyota alliance, and a 2017 rename to Subaru Corporation — the ownership history is calmer than Jeep's, but the aircraft-to-automaker throughline rarely makes it into a brochure.

Corporate origin
In 1945 the company that would become Subaru wasn't allowed to build anything. Nakajima Aircraft had spent the war making military planes; the occupation broke it apart. What reassembled in 1953 put a constellation on the hood of its first car — and the count behind that constellation turned out to be a small arithmetic trick, not a mystery.
provisional evidence · partial coverageEngineering identity
A WRX kid at a parking-lot meet and a Forester owner at a trailhead might not agree on a single thing — except that their engines lie flat and their all-wheel drive runs straight down the middle. Subaru didn't invent either idea. It just built an entire identity, and nearly its whole lineup, on the two of them together.
settled evidence · partial coverageControversy
Ask any Subaru forum and you'll hear it stated flatly, like a law of physics: the 2.5-liter boxers eat head gaskets. The pattern turns up everywhere you look — everywhere except the one kind of document that would make it official. This is a case file with a strong lead and no smoking gun, and we're not going to pretend otherwise.
provisional evidence · partial coveragePeople, not mythology
Subaru's history is full of famous marketing lines. The actual work is full of less-famous engineers, executives, and one very colorful US importer.

Split personality, one spine
NASIOC and Rebelle Rally forums barely overlap. A WRX owner and an Outback owner might disagree about almost everything else. But both can tell you their car has a boxer engine and Symmetrical AWD — the one fact this archive treats as the spine of the whole marque.
