An afternoon like dusk – The 604 story, Pt. 4

Engines! The 604’s was less than ideal.

Turning to the engine, one can see how an attempt to save money here also proved forlorn. The one clear advantage of using the 504 architecture was never exploited: the 604 never had the same range of engines as the earlier car. What it had was a 60° V6 engine designed in co-operation with Renault and Volvo.

As Motor pointed out in 1975, engine development requires a very large investment. Peugeot did not see the sales volumes of the 604 being large enough to justify designing a wholly new V6 on their own. This strategy certainly saved investment costs but did not lead to Peugeot having a competitive motor.

The powerplant faced the problem that it didn’t turn out quite enough motive force (though it was hardly slow by the day’s standards) and the 604 was a seen as a heavy car, presumably a result of an attempt to Continue reading “An afternoon like dusk – The 604 story, Pt. 4”

Theme : Engines – France

Do French engines live up to that nation’s fine engineering heritage?

In Post War Europe, engines were restricted by reasonably arbitrary taxation classes. In Britain, the old ‘RAC Horsepower’ rating was based on an archaic formula that related to the bore only, not the stroke and didn’t actually refer to the actual output of the engine.

Despite it being abolished in the late 1940s, it meant that the longer stroke engine, with its relatively low rev limit, lived on far longer in much loved stalwarts such as the Jaguar XK and BMC A Series and it did stem the development of lighter, freer running engines.

Italy was less prescriptive and, although there were aberrations, like home market only 2 litre Ferraris and Alfas V6s, it allowed the development of the sweet engines found in the Alfas and Fiats of the 60s. The French tried to Continue reading “Theme : Engines – France”
