The team

Small grid slot.
Big intentions.

Propel Motorsport is the smallest possible race team: a father and son, one C1, and the most patient pit crew in the family.

C1 endurance is the best racing bargain in the UK: near-identical ~68 bhp Citroën C1s, grids the size of Le Mans, and races that run three hours to twenty-four. Speed is capped; craft isn't. That's the appeal.

We debut at Snetterton this September, then aim to contest the full 2027 season, including the famous Silverstone 24 Hours.

It wasn't always pink.

Three moments from the build.
Every one of them real.

“We have bought a C1.”

An ordinary red city car, found on Facebook Marketplace. A five-door, naturally. The roll cage would make us question that decision later.

C1 knowledge, shared

Ask the Pit Crew.

Our virtual garage neighbour has read the regulations, the club's build notes and stories from teams who've done it before. Ask a question; answers show their sources.

  • What brake fluid can I use?
  • What film goes on the windows?
  • How do rear shims work?
