Mulsanne’s Corner opens with the line “Answering the questions that no one else is asking,” then backs it up with enough race-car engineering material to make a casual Le Mans fan regret clicking during lunch.
Michael J. Fuller’s site says it was created on August 1, 1998. The layout still recommends an 800Ă—600 screen resolution. The contents, meanwhile, range across decades of prototype racing: Audi R8 and R10, Bentley Speed 8, Toyota GT-One, Porsche 962, Jaguar XJR-14, Nissan prototypes, Panoz, Courage, Lola, Cadillac, Peugeot and plenty of cars that require a fairly committed motorsport brain to recognize.
The car pages are only part of it.
There are engine sections, interviews with drivers and engineers, historical pieces, technical regulations, scale-modeling references, Le Mans trap-speed data, and a race-car aerodynamics database.
Numbers instead of adjectives
Motorsport writing can turn into a fog of “aggressive aero” and “advanced design” very quickly. Mulsanne’s Corner is useful because it often gets specific.
The archive includes downforce and drag figures, aero balance, chassis regulations by year, technical drawings, development history, and explanations of concepts such as diffusers and wing endplates. One long-running feature asks why the Mercedes-Benz CLR became airborne at Le Mans in 1999.
The site also preserves rulesets that would otherwise be annoying to reconstruct. Its chassis-rule index stretches through years of ACO, FIA and IMSA regulations. For somebody researching why a particular prototype looks the way it does, that context matters.
And somehow this is not merely a fossil. The homepage shows updates in 2026.
What a specialist site can become
This is one of the best arguments for letting a personal website become absurdly specific.
No general automotive publication is likely to maintain a quarter-century cross-reference between obscure prototype chassis, historic rules, aerodynamic data, interviews and engineering notes. A focused independent site can.
That specificity is also SEO without the embarrassing part. Search for a particular chassis designation or technical question and there is a good chance the useful page is already sitting here.
