STAGE 4 COMPLETENESS GATE — WEBSITE BASELINE

Дата актуальности: 2026-08-13 Stage: 4 — POWERTRAIN NORMALIZATION Decision: BASELINE PASS / CLOSED FOR WEBSITE

1. Purpose

редакционная глава is the closing baseline pass for the powertrain stage before the encyclopedia becomes a website data source. It does not pretend that every homologation code, build-month suffix or low-volume market calibration has been exhausted. It establishes a stable, source-traceable core that can be consumed by the site without renumbering or collapsing technical distinctions later.

2. Frozen website baseline

After редакционная глава:

• ENGINE MASTER: 270 revision/application rows (ENG-0001…ENG-0270);
• HYBRID POWERTRAIN MASTER: 100 component/system rows (HYB-0001…HYB-0100);
• ELECTRIC DRIVE MASTER: 37 rows (EDR-0001…EDR-0037);
• identifiers are append-only from this point forward;
• no website implementation may renumber existing ENG/HYB/EDR IDs.

Machine-readable exports are stored in exports/website-baseline/.

3. What редакционная глава closes

Current combustion / M revision boundary

BMW M Ignite is treated as a real technical revision because the combustion system changes to patented pre-chamber ignition even where displacement and headline output remain unchanged. M3/M4 states begin in July 2026 and M2 states in August 2026.

Current 48V/PHEV matrix

G45 X3, G60 5 Series PHEV, G70 7 Series, current G05 X5 and the autumn-2025 M Performance 48V update are normalized with component/system separation. A motor contribution is never subtracted from or added to an official system figure to manufacture an unpublished ICE/system value.

Current BEV / Gen6 boundary

The ledger now contains:

• i4 SiC power-electronics revision;
• revised i5 states;
• iX3 40 Gen6;
• i3 50 xDrive Neue Klasse, promoted to current serial production after BMW confirmed Munich SOP in August 2026;
• 2026 i7 battery/charging revisions.

4. Gate rules retained permanently

1. No badge-to-engine-code inference.
2. No arithmetic hybrid system power. BMW-published system output wins over component summation.
3. No arithmetic BEV system power. Front/rear motor maxima are component capabilities, not a guaranteed simultaneous vehicle maximum.
4. No silent PS/hp/bhp conversion. Source-native units remain source-native.
5. No battery-value inheritance across revisions. If a current update does not restate capacity, that field may remain н/д.
6. No future-market laundering. Published technical states with future market launch stay marked LAUNCH-BOUNDARY.
7. Append-only IDs after редакционная глава.

5. Non-blocking forensic backlog

The following are intentionally not blockers for website launch or Stage 4 baseline closure:

• exhaustive option-843 reduced-output homologation states;
• every country-specific emissions/homologation code;
• exact full suffix for every B48/B58/S58/S68 application where BMW public material does not print it;
• every build-month micro-change where no distinct public technical state is proven;
• exhaustive legacy M10/M30 and pre-war engine suffix archaeology;
• future G65/G78/iX5 and other vehicles still behind the current/future production boundary;
• motorsport-only power units and aftermarket tunes.

These are moved to FORENSIC / VARIANT BACKLOG, not silently declared complete.

6. Stage decision

STAGE 4 CORE POWERTRAIN NORMALIZATION: PASS.

The three master ledgers are sufficiently normalized, source-traceable and structurally stable to freeze as the website baseline. Future research may append rows and improve quarantined fields, but it must not rewrite the identity of already-published rows without an explicit correction record.
