How many other car manufacturers can you think of that produce an entire range of cars, from their wheel nuts to their crank-shafts, under just one roof, at one factory? Not many.

Aston Martin sources engine, body and electrical parts from outside the main plant at Gaydon, as does Jaguar. Even Morgan, that most bespoke of car companies, sources one or two components externally, including quite a few trees.

At Ferrari, though, everything except the cows that provide the leather is now made at Maranello. Since November, in fact, they’ve even been generating their own electricity in order to power the Scuderia’s various tooling facilities – to the extent that in January Ferrari sold power back to Italy’s National Grid.

As a result, Ferrari now claims that its plant at Maranello produces between 25-30 per cent less CO2 than it did before its new “Trigeneration” system fired up in November – in which mechanical power, heat and cooling are produced by just one source. And that’s real world emissions, by the way, not ones that appear in EU approved documents, and which mean not a great deal in the overall scheme.
