Peel microcars have become famous the world over in recent years. From TV appearances to being included in popular video games, many people now know about and have become fans of the single-seater P50 and the two-seater Trident.

The cars are marking their 60th anniversary this year, an event that was celebrated by bringing a number of the surviving vehicles back to the place where they were originally made.

Peel cars were built by a company called Peel Engineering that was based in Peel on the Isle of Man.

It’s easy to see how they got their name, but what exactly inspired inventor Cyril Cannell to come up with the idea in the first place will likely remain a mystery forever. Cannell died in 2008, but a small number of his cars remain, which is remarkable considering the low production numbers.

Only around 50 units of the P50 were ever made, of which fewer than 30 are known to have survived to this day. Around 86 Tridents were also built by Peel, of which fewer than 20 are believed to still be around.

Because of their rarity and increased popularity, prices for originals have skyrocketed in recent times. Getting an original version of either model will easily set you back a six-figure dollar amount now.

Having this many Peel cars—including the original P50 prototype that had the third wheel at the front and not at the back like the later production version—in one place at the same time made the anniversary celebration a pretty special affair.

For the ultimate commemorative photo shoot, the cars even went to the old Peel Engineering factory where some of the surviving ex-employees also joined the celebrations.

Both the P50 and the Trident were powered by a 49cc two-stroke engine that was supplied by the German firm DKW.

It produced 4.2hp, which was enough to propel the tiny machine to a top speed of 61km/h. Standing at 1,370mm long and 990mm wide, and weighing just 59kg, the P50 was officially recognized as the world’s smallest production vehicle by Guinness World Records.

Not all of the cars that attended the event were originals. A number of companies sell replicas these days, including one called P50 Cars that offers an electric version.

One of these P50 EVs joined the fun, but without its famous owner. The Union Jack-painted car you see above is owned by Eddie Hall, the world’s strongest man who despite his huge frame actually fits in it.
