Any time that Ferrari appends the name of one of their models with an “M”—for modificato, or modified—it generally means that it’s the final version of that model incorporating all the refinements and upgrades—and so it’s also arguably the best. That is probably a fair assessment of the 575M Maranello, a heavy revision of the 550 that preceded it. Ferrari sent the classically proportioned grand tourer back to Pininfarina for a nip and a tuck (mostly revised aerodynamics, intakes, and body-colored headlight surrounds), and then plunged under the hood to revise the Tipo F133E motor, punching it out a third of a liter to produce 508 horsepower, an increase of nearly 30. The 575M marked another highly significant milestone for the scuderia, as the first road-going V12 car to feature an F1-style gearbox. Few cars have the poise, effortless grace, and startling performance as the 575M Maranello, one of the best front-engined grand tourers ever produced.
