Ferrari 488 GTB

488 GTB is powered by a 3902cc (488cc per cylinder, thus the name) all-aluminium dry sump unit of the Ferrari F154 engine family.Turbocharged with two parallel ball-bearing twin-scroll turbochargers supplied by IHI/Honeywell and two air-to-air intercoolers, the compressor wheels are made of low-density TiAl alloy often used in jet engines to reduce inertia and resist high temperatures within the turbocharger. The engine produces 670 PS (493 kW; 661 hp) at 8,000 rpm and 760 N·m (561 lb·ft) of torque at 3,000 rpm This results in a specific power output of 126.3 kW (171.7 PS; 169.4 hp) per litre and specific torque output of 194.8 N·m (144 lbf·ft) per litre, both records for a Ferrari car.

Underbody vortex generators work to reduce air pressure beneath the car thereby increasing overall downforce. A larger rear diffuser works to increase the velocity of air exiting the underbody to further lower air pressure, in conjunction with active aerodynamic variable flaps that both reduce drag and increase downforce as controlled by a microprocessor. The increased size of the diffuser over the previous 458 requires the twin exhausts of the 488 to be positioned higher in the rear bumper

Ferrari 488 GTB has a weight to power ratio of 2.2 kg (4.85 lb) per horsepower
