Is the end in view for the once ubiquitous 2 Litre?

I’ve never liked 4 cylinders. Part of me has always lusted after pistons and capacity. How I envy a fellow correspondent on these pages his 5.3 litre V12. The only diesel engine I’ve ever been attracted to is Volkswagen’s ludicrous 5 litre V10, which made a mockery of diesel’s assumed economy but where the sheer numbers almost overcome my antipathy to fuel oil. Despite all this, the puritan in me has shown restraint and, in fact, the most cylinders I’ve ever owned in one engine is six and the largest capacity 2.8 litres. But it’s not all size. I like less than 4 cylinders too.

I have eternally fond memories of the Citroen Flat Twin and I’ve never been tempted by a Japanese 4 cylinder motorcycle, far preferring my V Twin. I got very excited by Fiat’s TwinAir engine and, despite getting the idea that the real-world consumption, and thus emissions, are less related to the paper ones than they might be, it remains an attractive proposition – if only they’d Continue reading “Theme : Engines – 2000, the Not-So-Magic Number”

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”
