Alfa Romeo's F1 car for 2023

The Alfa Romeo F1 Team officially unveiled their 2023 contender on February 7th. The C43 and it's already turning heads as one of the most beautiful cars on the grid. At the launch event in Zurich and Hinwil, Switzerland, drivers Valtteri Bottas and Zhou Guanyu pulled the covers off the lean, mean machine in a striking red and black livery designed by Alfa Romeo's Centro Stile. The team is looking to continue their path of constant improvement in the upcoming World Championship.

CGI images and videos of the C43 were also released to media and fans alike, showcasing the car's beauty and power. The unveil video highlighted the team's union of individuals, each playing an important part in the car's assembly and the team's success. The C43 was even made available in Augmented Reality, allowing fans to bring the car into their homes in an interactive journey developed by team partners JigSpace.

In an effort to bring the car back to the community, the C43 show car unveiled by the drivers was put up for auction via Memento Exclusives on f1authentics.com. The livery prominently features the team's brands, including Alfa Romeo and new title partner, Stake, as well as new acquisitions that underline the team's growing attractiveness to businesses in all sectors.

The technical team, led by Jan Monchaux, designed the C43 and powered it with a new Ferrari power unit. The car is an evolution of last year's successful challenger, the C42, but incorporates several updates and complete new parts due to the significant changes in regulations brought in by the FIA.

The launch event was followed by a meet and greet with fans and an online press conference with international media, showcasing Alfa Romeo F1 Team Stake's unrivaled levels of access and constant push for innovation. The C43's overall development path promises a steep improvement curve, and with the talented drivers of Bottas and Zhou Guanyu behind the wheel, the team is looking to make a big impact in the upcoming World Championship.

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. Recent years saw further developments aimed at making these the safest Formula One cars in history.

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 six fasteners which have regulated dimensions and coordinates. Following Romain Grosjean’s spectacular crash in Bahrain 2020, new safety measures have been introduced to make the fuel tank detach from the chassis in a safe manner in the event of a major crash.

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.

Since 2022, the fuel used by the power units needs to be composed by at least 10% bio ethanol, in a bid to make the sport more sustainable.

Tyres

2023 is the second season with a big change in tyres, with Pirelli providing new, low-profile 18’’ tyres to replace the 13’’ ones used until 2021. This switch is hugely relevant to road car development and represents one of the big unknowns going into the new season. Pirelli, the sole supplier to the whole of Formula One, has also worked to produce new compounds and tyre structures designed to avoid too much overheating when tyres slide too much.
