Robin
Reliant · on record 1994 to 2025
The Reliant Robin is Britain's best known 3 wheel economy vehicle, using a single front wheel, lightweight glass fibre body and small 4 cylinder engine. It was bought as inexpensive personal transport and benefited from licensing rules associated with the motor tricycle category. The model later became a cultural icon, which has helped enthusiast interest and survival. For analysis it should be separated clearly from conventional 4 wheel passenger cars.

Population history
Licensed and SORN vehicles at each census. The filters below apply to the family population, MOT and registration figures. They do not alter the generation history above.

SORN
Latest census observation
At the average decline recorded over the latest five years, the licensed fleet would reach zero around 2037.
Illustrative projection only; vehicle populations rarely decline linearly. Late fleets typically flatten as surviving examples enter preservation.
Inside the surviving fleet
AutoCensus parses every DVLA variant description, so the fleet can be read by fuel and specification rather than as one number.
First registrations by year
When surviving examples first joined the British fleet.
New registrations
Vehicles first registered each year. A fleet still being sold shows here; a finished one shows only imports.

Pass rate by year
| Failure reason | Failures | Share of all tests |
|---|---|---|
| A mandatory rear fog lamp inoperative or less than 50% of the light sources illuminating | 314 | 5.3% |
| A stop lamp inoperative or less than 50% of the light sources illuminating | 279 | 4.7% |
| Amalgamation of failures for all headlamp testers | 179 | 3.0% |
| A rigid brake pipe excessively chafed, corroded or damaged | 154 | 2.6% |
| A direction indicator inoperative or less than 50% of the light sources illuminating | 110 | 1.8% |
| A low braking effort is recorded from the parking brake on any wheel, indicating clearly that the brake is not functioning correctly | 105 | 1.8% |
| An obligatory lamp adversely affected by the operation of any other lamp, e.g. dual-function lamps on foreign vehicles. | 103 | 1.7% |
| A wiper blade insecure, missing or in such a condition that it does not clear the windscreen effectively to give the driver an adequate view of the road (through the windscreen) to the left and right sides of the vehicle, as well as to the front | 74 | 1.2% |
Counted across every recorded test, 2005 to 2025. Advisories are excluded.
Where the Robin remains
Based on MOT test locations, 2025. Test location is a proxy: a vehicle is counted where it was last tested, not where it is kept.

Full methodology
Population history combines DVLA VEH0120 Q4 census observations through 2013 with the annual VEH0220 census from 2014 onward. Figures before 2014 cover Great Britain only. Historical VEH0120 is used only when its overlapping UK observations reconcile to the current canonical family definition. Vehicles are grouped into this family using the DVLA GenModel together with durable routing rules for known inconsistencies.
Variant figures are parsed from raw DVLA model descriptions and the original string is always retained. Configuration is only assigned where the model description explicitly identifies it; a blank configuration is not treated as a two door Wrangler. Blank transmission fields are shown as manual because DVLA records the field for automatic vehicles.
MOT figures count tests, not vehicles, and geographic figures count each vehicle at its most recent test location. The decline projection is a straight line fitted to the latest five years and is illustrative only.
