Major normalization decisions

1. N13-era F20 rows do not receive an invented suffix because the current BMW release publishes architecture and calibration but not the code.
2. Exact B37/B47/B38/B58 codes from the official F20 LCI BMW technical PDF were used only after the PDF was visually audited.
3. B38B15M0 is allowed to have more than one calibration row. Exact code identity does not force an output merge.
4. N63/S63/S55/S58 revisions are split by application/calibration.
5. US-only lb-ft values are retained in notes/Hybrid source-native fields rather than silently converted.
6. Temporary torque/power states (M2 overboost, 330e XtraBoost) are marked as temporary and do not overwrite continuous ratings.

Hybrid gate

PASS — no component arithmetic masquerading as system output.

Examples:

• M340d: 340 hp ICE + 11 hp starter-generator is not recorded as a fabricated 351 hp system.
• 330e: BMW-published 252 hp base system and 292 hp XtraBoost state are separate rows.
• 2025 B58B30M2: 375 hp ICE, 11 hp starter-generator and BMW-published 386 hp system are separate records.
• BMW XM: 489-hp ICE and 197-hp e-motor remain components; 653 hp / 800 Nm is stored only because BMW publishes it as overall system output.
