R / production rarity
How rare is it?
A simple 1–5 rating based on completed worldwide production for this exact version. Price and desirability are not included.
The rating uses five fixed production bands. Smaller production runs receive higher ratings. Exact totals and responsibly sourced estimates for this precise version can be rated. Plans, regional totals, lower bounds, disputed figures and broader-family totals remain visible but unclassified. The evidence description is kept separate from the rating so a source limitation cannot change how scarcity is measured.
308 GTB Quattrovalvole (F106AB/Q) records one precise Ferrari performance-car configuration from 1982–1985. The Quattrovalvole update joined Ferrari’s compact transverse V8 berlinetta format to a new four-valve cylinder head.
At its centre is a 2,927 cc naturally aspirated v8 identified as F105AB. Ferrari publishes 176 kW (240 CV) for this scope. Four valves per cylinder restored output while retaining Bosch K-Jetronic injection and the transverse mid-engine package.
The engine is installed in a transverse rear-mid engine, rear-wheel drive layout and works through a 5-speed gated manual. Those facts matter acoustically as well as technically: engine position, firing order, induction, gear selection and cabin structure all affect what reaches a listener.
Engineering and character
Its nearest passport neighbour in this published sequence is the 365 GT4 BB. That relationship supplies chronology, not interchangeable specifications. Ferrari repeatedly evolved its V8 and twelve-cylinder families through body styles, competition derivatives and later technical phases. Keeping each boundary visible prevents attractive but incompatible facts or recordings from migrating between cars.
The listening cues flat-plane V8, gated manual, mechanical, high-revving are orientation rather than proof. A cold start can expose idle control and mechanical texture; acceleration can document induction, combustion and shift behaviour; a fly-by can place exhaust and tyre sound in an exterior context.
The focus here is the closed-roof 308 GTB Quattrovalvole. It excludes the GTS, earlier two-valve injected and carburettor cars, the 208 family and modified examples. Many surviving Ferraris have replacement exhausts or other period and modern changes.
Legacy and identity
It invites cold start, acceleration and fly-by recordings, plus photographs, documents and corrections.
Contributors are therefore asked for capture date, general environment, microphone and recorder details, engine temperature, operating load and any known deviation from factory specification. Private location and ownership details stay out of the public record. This practical metadata lets later researchers distinguish mechanical character from recording technique while leaving room for a corrected identity or a better documented replacement.
Preservation means keeping each claim inspectable and correctable.
