Tertre Rouge Group C-inspired Race Car

A UK-based individual, Mark Sparrow, has revealed preliminary information about his project to construct a road-legal endurance racing vehicle that takes inspiration from the legendary Group C race cars of the 1980s. Named Tertre Rouge, after a turn on the Circuit de la Sarthe used in the 24 Hours of Le Mans, the project is a lifelong dream for Sparrow, who first witnessed Group C race cars in action at Le Mans in 1989.

Audi Q3 Overview

Mark Sparrow’s background is in mechanical engineering. Previously, he was part of the team behind the BepiColombo space probe that is en route to Mercury. Currently, he manages his own contracting business in the aerospace sector. When not engaged in aerospace endeavors, Sparrow concentrates on the Tertre Rouge project, which he aims to make road-legal in Europe, circumventing stringent crash testing regulations typically imposed in the United States.

Performance Objectives

Sparrow’s ambition for the Tertre Rouge is to equal or surpass the performance benchmarks set by Group C legends like the Mazda 787B and the Porsche 956. Unlike most modern cars, the vehicle will feature minimal electronic driver aids, including the absence of electronic stability and traction control systems.

Technical Specifications

The Tertre Rouge is to be built on a steel tube-frame chassis that incorporates an integrated roll cage. Its body will be crafted from an assortment of composite materials, targeting a total weight of approximately 2,100 pounds. The engine will be a twin-turbocharged 5.0-liter V-8, derived from a 1990s Mercedes M119 design, with an estimated peak power output of around 750 horsepower. Power will be transmitted to the rear wheels through a six-speed sequential gearbox sourced from Elite Transmissions, a UK firm specializing in racing transmissions.

Aerodynamic and Testing Plans

Aerodynamic testing will be conducted in wind tunnels and on racing circuits, such as Donington Park Circuit in the United Kingdom. According to Sparrow, the aerodynamic design of the car’s body will be fine-tuned to handle speeds nearing 250 miles per hour.

Production and Future Plans

Sparrow anticipates commencing production of the Tertre Rouge around the year 2025. A limited run of no more than 20 units is planned, each with a price tag of approximately 750,000 British pounds (or roughly $911,000). Revenue generated from these sales will be allocated toward entering the vehicle in racing competitions. Potential events include endurance races at the Nürburgring and possibly even historic racing events specifically designed for Group C cars. Ultimately, Sparrow’s aspirational goal is for the Tertre Rouge to participate in the iconic 24 Hours of Le Mans race.

Love how this is a nod to Group C cars like the Mazda 787B and Porsche 956. Keeping the spirit alive while making it road-legal is a cool concept.

20 units at about £750k each, that’s quite an investment. Curious to see if it will pay off when he takes it racing.

£750k for one of these? steep price but if it delivers, I can see collectors lining up for it.

A corner from Circuit de la Sarthe as the name, thats a nice touch. It would be awesome if this car actually races at Le Mans one day.
