The 488 GTB is powered by a 3904cc (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 Nm (561 lbft) 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 Nm (144 lbfft) per litre, both records for a Ferrari car.TransmissionThe only available transmission for the 488 is an automated manual dual-clutch 7-speed F1 gearbox manufactured for Ferrari by GETRAG, based on the gearbox used in the 458.HandlingImproved carbon-ceramic brakes are supplied on the 488, derived from technology used in LaFerrari, constructed with new materials that reduce the time needed to achieve optimum operating temperature. Disc sizes are 398 mm at the front, and 360 mm at the rear. These advancements reportedly reduce stopping distances by 9% over the 458.A new 5-spoke alloy wheel was designed for the 488, measuring 51 centimetres (20 in) front and rear. Front tires measure 245/35 with rears 305/30.The 488 GTBThe first 488 to be introduced was the 488 GTB 2-seat berlinetta, successor to the 458 Italia. It was launched on 3 February 2015, in advance of its world premire at the March 2015 Geneva Motor Show.Claimed manufacturer performance for the 488 GTB is 0100 km/h (062 mph) in 3.0 seconds, 0200 km/h (0124 mph) in 8.3 seconds, covering the quarter mile in 10.45 seconds and continuing to a top speed in excess of 330 km/h (205 mph).DesignThe body of the 488 has been designed to increase downforce by 50% over the 458 while reducing aerodynamic drag. A new front double splitter increases radiator cooling while a newly designed blown rear spoiler (actually a slotted flap) integrated into the rear decklid and bumper increases downforce without requiring a raised wing. The central Aero Pillar deflects air under the flat body of the car while two vents in the bonnet provide an exit for air from the dual intakes of the front bumper, further reducing air pressure over the front of the 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 for clearance.The scalloped side air intakes are a homage to those found on the 308 GTB, and are divided by a central partition. Air entering the top intake is partially directed into the turbocharger compressor intake, while the rest is directed through the rear of the car and exits alongside the rear lights, increasing air pressure behind the car in order to reduce aerodynamic drag. Airflow entering the lower intake is directed towards the intercoolers in order to cool the intake charge.
