FERRARI 488 GTB


Forty years on from the unveiling of Ferrari's first ever mid-rear-engined V8 berlinetta, the 308 GTB, the Prancing Horse opens a new chapter in its 8-cylinder history.

The 488 GTB name marks a return to the classic Ferrari model designation with the 488 in its moniker indicating the engine's unitary displacement, while the GTB stands for Gran Turismo Berlinetta. The new car not only delivers unparalleled performance, it also makes that extreme power exploitable and controllable to an unprecedented level even by less expert drivers.
An exceptional engine and sophisticated aerodynamics combined with refined vehicle dynamic controls radically improve the already razor-sharp responsiveness of Ferrari's road cars to near-track level.

Technical specification :

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 tremendous performance figures are the result of a focus on achieving maximum efficiency across the
board. In terms of combustion, this means new specially-shaped high-tumble intake ports 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.
Mechanical efficiency is guaranteed by an oil pump that supplies oil either at high pressure or low pressure. Cylinder heads with roller finger followers reduce thepower absorbed by the valvetrain by 10 per cent at low revs thanks to reduced friction. The use of flat-plane crankshaft architecture guarantees maximum compactness, lower mass and helps improve the engine’s internal fluid-dynamics.

Numerous components contribute to the powertrain’s exceptional response times. 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. the exhaust gases from each cylinder through separate scrolls and increases the efficiency of the exhaust pulses for maximum power.

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.
