However, except for these e-turbos, Ferrari mastered all these items years in the past. It’s the hybrid parts and software program engineering that demonstrates what a fast trajectory these guys at the moment are on. Reasonably than counting on exterior suppliers, Ferrari is taking cost, having lately opened the brand new “E” constructing. Its first absolutely electrical automotive is because of seem this time subsequent yr, however the {hardware} is already in manufacturing on this expansive Mario Cucinella–designed house.
The electrical motors used on the F80 are thus totally proprietary, with the intention of maximizing efficiency whereas minimizing weight. There are two on the entrance axle and one on the rear, to ship torque vectoring and all-wheel drive.
The electrical entrance axle additionally homes an inverter and cooling system, the entire meeting weighing simply 61.5 kilograms. That’s 14 kilograms lower than the equal set-up on the SF90 mannequin. The inverter is bidirectional, in order that alternating present produced by the e-axle beneath regenerative braking is changed into direct present to cost the battery. The inverter on the rear MGU-Ok e-motor is used to begin the combustion engine, get better power to the battery, and supply torque-fill beneath load. Each inverters are ruled by an extremely compact management module.
The e-motor’s stator and rotor sit in what’s referred to as a Halbach array, which targets and maximizes the density of the magnetic subject. The magnets’ sleeve is manufactured from carbon fiber, permitting it to spin at as much as 30,000 rpm. Each are options derived from System One. A singular DC/DC converter implies that one element can deal with 800 V, 48 V, and 12 V concurrently. Ferrari says it has a conversion effectivity of 98 %, and it reduces weight and complexity.
The excessive voltage battery (860 V, in reality) can also be straight influenced by F1: 2 hundred and 4 lithium cells are grouped in three modules in a carbon fiber case that sits low within the chassis to take care of an optimum middle of gravity. It’s all in the help of efficiency: Not like the 296 GTB, there isn’t any EV mode on this factor. With a dry weight of 1,525 kilograms, it’s 125 kilograms heavier than the McLaren W1, however its British rival lacks an electrified entrance axle, and thus the Ferrari’s torque vectoring and all-wheel drive.
Unbelievable Aero

Just like the Aston Martin Valkyrie and W1, the F80 makes use of floor impact aerodynamics. In whole, it might probably generate 1,000 kilograms of downforce at 155 mph, a metric to conjure with on condition that that is primarily a highway automotive.
A entrance triplane wing impressed by the system used on the Le Mans–profitable 499P, flat underbody, S-duct, raised “keel,” rear diffuser, and energetic rear wing all work in tandem with the F80’s energetic suspension to generate unprecedented stability with out hurting the automotive’s on-road dynamics.
