What the United Motors of America filings say about the engines
Every United Motors of America filing on record is carburetted — 12 certificate rows, 2007 to 2009, and not one fuel-injected engine among them.
All 12 filings are 50-state certifications, so every one of these machines was certified for sale in California.
Rated power across the range runs from 5.9 kW to 6.7 kW (about 8 to 9 hp).
The vehicle builders named are Skyteam Corp. Ltd. and Zhejiang Taizhou Wangye Power 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.
The factory changed. Here is when.
| Model year | Engine factory on the certificate |
|---|---|
| 2009 | Zhejiang Taizhou Wangye Power |
| 2008 | Skyteam Corp. Ltd. · Zhejiang Taizhou Wangye Power |
| 2007 | Skyteam Corp. Ltd. |
