What the Boss Motor filings say about the engines
Boss Motor's filings mix carburettors and fuel injection: 17 rows carburetted, 3 injected. The first injected family appears in 2024; in 2026 the split was 5 carburetted to 1 injected. Check which you have before buying anything on the fuel side.
The engine codes on Boss Motor's test vehicles —5 distinct across the filings — are led by 1P52FMH, 1P54FMI, 161QMK-A, 139QMA and 161QMK. The code is stamped on the crankcase and is a better search term than the badge.
14 of the 20 filings are 50-state (California-legal); the other 6 were 49-state only.
Rated power across the range runs from 2.2 kW to 7.6 kW (about 3 to 10 hp).
The vehicle builders named are Ningbo Dongfang Lingyun Vehicle Made Co., Ltd. and Ningbo Ultima Locomotive Technology Co.,Ltd. — the chassis and the engine do not always share a source.
Each figure is read straight off the EPA certificate rows; the per-family pages below carry the full breakdown for every engine family.
