Alfa Romeo Racing C41

Survival cell

The survival cell is the heart of the entire car and by far the most complicated structure in a modern Formula One car.

The survival cell is made from a sandwich style carbon composite structure. It offers superior stiffness to weight ratio and structural integrity.

The survival cell accommodates the driver’s cockpit area and it is secured to the engine and gearbox by 6 fasteners which have regulated dimensions and coordinates.

Power unit and gearbox

In the current era of hybrid Formula One power units, the main power source is provided by a V6 1600cc engine, mated to a single turbocharger. The energy harvested during a lap by two electric motors (MGUK and MGUH) is stored into a battery pack and deployed via a 120kW electric motor.

The gearbox has 8 forward gears and 1 reverse gear.

The entire drivetrain is supplied by Ferrari.

Tyres

A change in the regulations has seen a standardised tyre allocation being brought in for 2021, with drivers – unless otherwise determined by the FIA and with the agreement of Pirelli – set to receive two sets of hard tyres, three sets of mediums and eight sets of softs per race weekend.
The Pirelli tyres feature more robust compounds than in the past, a change introduced by the Italian manufacturer after 2020 saw some of the highest cornering forces in the history of the sport.
