The latest 12-cylinder creation from Ferrari, the aptly named 812 Superfast, may appear to use the same V12 powerplant as the F12 Berlinetta and tdf, however a sizeable jump in displacement from 6,262cc to 6,496cc, and 75% all-new parts and subsystems, means this latest naturally aspirated heart from the Prancing Horse is bona fide new.
And if you don’t include the mid-rear- engined limited-series specials, then the 812 Superfast is also Maranello’s most powerful and fastest road-going car yet, developing an incredible 800ps at 8,900rpm and 718Nm of torque at 7,000rpm (80% of which is available at 3,500rpm). This means output has been boosted by 60ps and 28Nm compared with the F12 Berlinetta.
Furthermore, with the increase to 6.5 litres, the new V12’s stroke has gone up to 78mm from the 6.2’s 75.2mm. And while the bore remains at 94mm, there’s a slight change in compression ratio, from 13.5:1 to 13.6:1. On the efficiency front, a 350-bar direct injection system (developed by Bosch) is used for the first time on a spark-plug engine. Along with the 812’s stop/start capability, it means that a reduction in CO2 of 20g/km has been made over the V12 Berlinetta, with the official 812 NEDC CO2 rating being 340g/km.
While most of the development targets for this new engine were based on power and performance, sound quality – in true Italian style – was equally important for Ferrari. Thus, the exhaust geometry system increases and balances the sound from the engine compartment and tailpipes, with a six-in-one equal-length pipes exhaust manifold.
“Bigger, better and badder, the latest 6.5-litre version of Ferrari’s naturally aspirated V12 is more magnificent than ever,” enthused jury member John Carey, while fellow judge Nikos Kounitis predicted: “One day, when batteries and electric motors have prevailed and vehicles drive autonomously, petrolheads will glorify Ferrari’s V12 as one of the final great acts of defiance of the IC engine era.”
