Reliant Robin: The Three-Wheeler That Turned a Tax Rule Into a National Treasure

Every country has a car that it laughs at and loves at the same time. In Britain, that car has three wheels and one of them is at the front.

Born in Tamworth

The Reliant Motor Company of Tamworth, Staffordshire, had been building three-wheelers since the 1930s. In October 1973 it launched the Robin as a replacement for the Reliant Regal. Ogle Design styled it, and the body was fibreglass, so it would never rust, while under the bonnet sat Reliant's own all-aluminium four-cylinder engine. It started at 748cc and grew to 848cc in 1975.

It turned up at just the right moment. The 1970s fuel crisis made a light, frugal car very appealing.

The three-wheel loophole

Why three wheels? Mostly for the paperwork. Because the Robin was a three-wheeler weighing under 450 kg, it could be driven on a B1 licence and taxed at lower rates than a normal car. Until 2001, people who passed the motorcycle test were granted B1 entitlement. That's where the famous claim that you could "drive a Robin on a motorcycle licence" comes from. It's a muddle of a story, but it was a real selling point for a generation of drivers.

The tipping legend

The Robin's big reputation is falling over. One wheel up front does make it less stable in hard cornering than a four-wheeler. The legend went into overdrive in 2010, when Top Gear showed a Robin rolling over again and again under Jeremy Clarkson.

Years later, Clarkson admitted in a newspaper column that the car had been rigged: the team had modified it so it would roll on cue, and he said a normal Robin would only roll in extreme circumstances. So the most famous evidence against the Robin was staged comedy.

The long goodbye

The original Robin ran until the early 1980s and was replaced by the Rialto. The Robin name came back in 1989 in an updated Mk2. Reliant stopped building it around 2000–2001, marking the end with a run of gold-coloured, leather-trimmed "Robin 65" specials. A small firm, B&N Plastics, then built roughly 40 more under licence before giving up in October 2002.

Why we love it

The Robin is a glorious mistake in the best sense. Three wheels was the wrong answer to "how do you build a car?" and exactly the right answer to "how do you build a car people can afford to run?" It's light, rust-proof and thrifty, and no other car makes a whole country grin quite like it.
