The new V8 sported by the 488 GTB is the Maranello engineers’ latest response to the challenge to constantly set new benchmarks of excellence. This 3902 cc power unit is the Prancing Horse’s most high performance engine ever with zero turbo lag and a unique, seductive soundtrack. It delivers 670 cv at 8,000 rpm with a specific power output of 172 cv/l, a new record for a road-going Ferrari, maximum torque of 760 Nm in seventh gear and a throttle response time of just 0.8 seconds at 2000 rpm in third gear. Consequently, the 488 GTB sprints from 0-100 km/h in 3 seconds flat and from 0-200 km/h in just 8.3. These superb performance figures are the result of a focus on achieving maximum efficiency across the board. In terms of combustion, this means new high-tumble intake ports specially shaped to optimise the flow coefficient and swirl motion in the combustion chamber for a homogeneous charge even at high revs, combined with 200-bar direct fuel injection. The new V8 also has an ion-sensing system which measures ionising currents to control ignition timing and adaptively predict misfires, as well as a multi-spark function which enables the spark advance to be maximised at all revs. Mechanical efficiency is guaranteed by an oil pump that supplies oil either at high pressure or low pressure, reducing hydraulic power requirements by up to 30 per cent compared to a conventional pump. Cylinder heads with roller finger followers reduce the power absorbed by the valvetrain by 10 per cent at low revs thanks to the reduction of friction between the valve stems and the tappets and the camshafts and the finger follower roller. The use of the flat-plane crankshaft architecture guarantees maximum compactness, lower mass and helps improve the engine’s internal fluid-dynamics by ensuring equal pulse spacings and thus balance between the cylinders. The turbos are on ball-bearing-mounted shafts to reduce friction and the compressor wheels are in TiAl, a low-density titanium-aluminium alloy, which, thanks to its lower inertia, ensures maximum spool-up speed. In addition, twin-scroll technology directs the exhaust gases from each cylinder through separate scrolls and increases the efficiency of the exhaust pulses for maximum power. A special seal on the turbine housing ensures a minimum gap between it and the compressor wheel for maximum efficiency. All these solutions contribute to the class-leading response time with zero turbo lag. As the revs rise, the V8’s soundtrack increases in volume and clarity, in line with the increase in power. Pivotal to the sound in the cabin are the exhaust headers with longer, equal-length tubing and the flat-plane crankshaft. The soundtrack was further enhanced by an in-depth study of the harmonics and tonality at different engine speeds, another area in which Ferrari has always excelled.
