|---|---|---|
| 1–3 | 1GT | GENERAL MOTORS LLC · World manufacturer identifier |
| 4–8 | 524C8 | Model, body style, engine and restraint system |
| 9 | × | Check digit — computed per vehicle, not part of the build |
| 10 | B | Model year — 2011 |
| 11 | × | Assembly plant |

Where this data comes from
Specification fields are decoded from the manufacturer's filings in the NHTSA vPIC database, keyed on VIN positions 1–8 and 10. We publish the filed values as they stand and leave out anything the filing does not record.
Vehicle counts come from the 33 VINs of this build we have seen in dealer inventory. They are a sample of the road population, not a production figure.
