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 be more scientific, with a fiscal horsepower tax that brought in various factors but, generally, encouraged smaller engines of 4 cylinders and less. Thus, in a country that has a fine record in technical advances in motoring, engines struggled to keep up.
