Getting more from Ferrari’s V12 is ‘really hard work’
Electric cars have, when it comes to power outputs at least, gone from a low baseline to a position of absolute dominance. The combustion engine has been fastidiously evolved for more than a century, specific outputs rising only incrementally as devoted acolytes nurse marginal gains from this curious device of world-changing potential. New understanding brings a little more compression here, a touch less friction there, a few more revs without catastrophe. Take Ferrari’s 6.5-litre V12. Chief technical officer Michael Leiters and his team engineered an all-new valvetrain, lightened and re-balanced the crank and adopted titanium conrods, all to take peak power from 789bhp (812 Superfast) to 818bhp (812 Competizione). It was, Leiters admits, ‘really difficult work’. The V12 in Ferrari’s first car, the 1947 125 S, was good for 79bhp per litre; the…
