The Ferrari 308 GTB Quattrovalvole, introduced in 1982 as an evolution of the 308 GTB, was produced until 1985. Approximately 3,042 units were built, making it a relatively rare model in Ferrari's history, especially compared to later production runs. Designed by Pininfarina, it features a distinctive wedge-shaped body and remains an iconic representation of 1980s automotive design. The "Quattrovalvole" name refers to its four-valve-per-cylinder configuration, an upgrade over earlier 308 models, enhancing engine performance.

Powered by a 2.9-liter V8 engine, the Quattrovalvole delivers 230 horsepower in European specification (slightly less in U.S. models due to emissions regulations) and achieves a top speed of around 155 mph with a 0-60 mph time of approximately 6.5 seconds. Its mid-engine layout and lightweight fiberglass body (in early GTB versions) contribute to balanced handling, a key draw for collectors. As a final iteration of the 308 series, it holds historical significance as a bridge to the later 328 model. Values have risen in recent years, often exceeding $100,000 for well-maintained examples, with low-mileage or original-condition cars commanding premiums in the exotic car market.
