67 Years of British Engineering

The Founders

Jem Marsh

Racing driver, engineer and tireless promoter, Jem Marsh co-founded Marcos in North Wales in 1959. Across six decades he remained the driving force behind the marque, championing its motorsport ambitions and racing many of the cars he built.

Frank Costin

Aeronautical engineer behind the de Havilland Mosquito and designer of the first Formula One championship-winning monocoque chassis, Frank Costin brought aircraft thinking to car design. His brother Mike Costin co-founded Cosworth, leaving the Costin name written across decades of British motorsport.

Lightweight, Innovative, British

With designers like Dennis Adams, Jem and Frank built a run of lightweight, innovative British sports cars, from the Mantis XP to the Mini Marcos and the Mantara, known for distinctive design and real performance.

From the LM600 at Le Mans to the Mantis XP at Goodwood, a Marcos always stood out. The last production model, the TSO GT, arrived in 2007, developed with Tony Stelliga and Damian McTaggart (designer of the TVR Cerbera, Tuscan and T350).

A New Chapter for Marcos

In 2010, ex-Formula One and IndyCar engineer Tony Brown acquired the marque, the brand rights and the Marcos name through Marcos Cars Ltd (registered in England and Wales, Company No. 07446000). With the Marcos Owners Club, his team built the mid-engined Spirit 220 prototype, run at Prescott Hill Climb with the blessing of original designer Dennis Adams.

Now partnered with entrepreneur William Storey, Marcos has secured new investment and assembled a team of British engineers with Formula One experience, a media team led by Geno White, and the backing of industrialist Anthony Barrow. The new car launches in Autumn 2026.
