The "Ferrari 627 Indy" likely refers to the Ferrari 637, a turbocharged IndyCar built by Ferrari in the mid-1980s to compete in the CART series, especially the Indy 500, as they considered leaving Formula 1 due to turbo regulations. It featured a powerful 2.65L turbocharged V8 engine, carbon fiber chassis, and upward-pointing exhausts. Though promising and fast in testing, the project was scrapped when F1 changed its rules, preventing Ferrari from racing it competitively in IndyCar, leaving it a fascinating "what if" in motorsport history. 

Key Details:

Name: Ferrari 637 (not 627).

Purpose: To enter the American CART Championship (IndyCar).

Engine: 2.65L, 90-degree turbocharged V8.

Chassis: Carbon fiber lower frame with an aluminum upper body.

Development: Built as a response to the turbo era in F1 and a potential shift away from it.

Outcome: Abandoned due to FIA rule changes in F1 and strategic concerns, never raced competitively. 

Why it Matters:

The 637 represents a significant moment where Ferrari almost left Formula 1 for American open-wheel racing, showcasing their ambition and engineering prowess in a different discipline, though it ultimately remained a tantalizing concept rather than a race winner.
