Volvo does not build many cars like the Volvo B7F with 6.7-litre front-mounted I-6, built from 1978 as the oil crises and the first emissions rules rewired the industry.
Where it came from
Volvo B7F and Volvo B7FA were a series of front-engined single-decker bus chassis manufactured by Volvo. While the B7FA was a more conventional front-engined chassis, the B7F had the engine mounted on top of the front axle, giving the buses very little front overhang. The models are not known to have been available in Europe, but they could at least be found in Latin America, New Zealand and South Africa.
Under the skin
Under the skin sits 6.7-litre front-mounted I-6; other versions carried different engines, listed in the specification table below. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
In context
Where it sits in Volvo's history is not in doubt: the Volvo BB57 (B7F) / Volvo B57 (B7FA) came before it; the Volvo B270F followed it. On a showroom list of its day it stood against the GM (General Motors) Saab 900, the Mazda RX-7, the Toyota Supra. Nearby in the Volvo catalogue sit the Volvo 144 and the Volvo 264 TE.
The money
MotorJury scores cars on the United States complaint and recall record, and the Volvo B7F has none: too old, too rare, or never sold there. Its value today is a collector's question, decided by provenance and condition rather than by a class average.
