The Ferrari SF90 is a Formula One racing car designed and constructed by Scuderia Ferrari to compete during the 2019 Formula One World Championship. The car is currently driven by Sebastian Vettel and Charles Leclerc. The car made its competitive debut at the 2019 Australian Grand Prix.

Background[edit]

Ferrari designed and constructed the SF90 as a Formula One car to compete during the 2019 Formula One World Championship.[2] The car is being driven by four time world champion Sebastian Vettel and Ferrari debutant Charles Leclerc and has driven in every race of the 2019 season to date.[3] Ferrari named the car the SF90 to celebrate the companies 90th anniversary and in keeping with tradition Vettel named his car "Lina".[4][5]

Initial design[edit]

The new regulations for the 2019 season meant that the teams had to adopt a new simpler front wing design and a higher and wider rear wing. Ferrari produced a radical front wing design, that tapered downwards from the middle towards the endplates of the wing, whereas Mercedes and Red Bull, their nearest rivals, went with a conventional design that is high from middle to end. This design was meant to encourage flow around the tyres with the front wing being below the maximum allowed height.[6][7] Ferrari's front wing design meant that the majority of the loading would be felt on the middle of the wing and this in turn would cause the air flow to be directed to within the front tyres. This design would make the car more predictable with its downforce levels but give less downforce overall.[8]

An anonymous senior aerodynamicist therefore commented that because the front wing wasn't creating as much downforce as the front wing's of some of its rival cars Ferrari would have to compensate the aerodynamics of the rest of the car. The anonymous aerodynamicist further commented that because the front wing didn't generate as much downforce Ferrari instead had to compensate and increase the size of their barge boards to provide this downforce. This in turn meant that rear would be unable to produce as much downforce as the front going forward in the development of the car. This would likely lead to a car prone to oversteer, therefore it was anticipated that the SF90 wouldn't develop as fast as some of its rivals and the amount of downforce the car would produce would be limited.[8]

Ferrari also changed the engine cover on the SF90 making it smaller compared to the engine cover on the SF90's predecessor the SF71H in order to save weight and for aerodynamic purposes,.[9] Ferrari also adopted a matte finish to the car's livery instead of gloss to save weight.[10] The SF90 also had a reworked cooling system with the engine cover developing a smaller inlet, now triangular rather than oval and the raditor air inlets were made larger. The rear bodywork was also remodeled suggesting an increase in rear aerodynamic performance.[11]

Pre-season testing[edit]

Ferrari took a few upgrades to the first test. The most notable of these was the location of the exit for the air that would have come through the side pod. Instead of the traditional place of letting the air out of the rear of the car the SF90 redirected some of the air out behind the base of the halo. This would have 2 advantages, the first would be that by bringing the air up there is would help to generate extra downforce in the middle of the air and the second benefit would be that the SF90 would be able to manipulate the air flow to its rear wing. A second upgrade that Ferrari brought to the first test was with the wheel. The wheel rim was redesigned with holes in it to transfer heat away from the tyres thus keeping the tyres in their operating window. Although this innovation wouldn't help with the SF90's outright pace it would allow the SF90 to take better care of its tyres therefore improving the cars race pace.[12] After the first week of pre season testing it was the SF90 which had the clear advantage having completed a high number of laps and with both Leclerc and Vettel commenting how comfortable they felt with the car.[13] Although the SF90 finished in 8th and 9th after the first test they only used the harder and therefore slower tyres, when the times were adjusted to show predicted lap time had they all been on the same tyre it was predicted that the SF90 would have been the fastest.[14][note 2]

Season performance[edit]

Ferrari entered both the Belgian and the Italian Grands Prix as favourites with a car which is highly suited to the circuits.[16] Charles Leclerc subsequently won both races taking his debut win at the Belgian Grand Prix though both Grands Prix were only won narrowly with Mercedes finishing second and third on both occasions within a second of Leclerc. Vettel meanwhile finished fourth in Belgium and 13th in Italy following a collision with Lance Stroll.[17][18][19] For the following race, the Singapore Grand Prix, Ferrari introduced new aero updates with new fins on the car's floor and a new nose in a bid to improve downforce among other smaller changes to the cars aerodynamics.[20] The team managed a 1-3 qualifying result and Vettel won the race from pole-sitter Leclerc to secure Ferrari's first 1-2 finish since the 2017 Hungarian Grand Prix, and Vettel's first win since the 2018 Belgian Grand Prix. Ferrari continued to show their improved pace in the Russian Grand Prix, with another 1-3 qualifying result. However, a nonstandard Mercedes strategy, a mechanical retirement for Vettel, and a Virtual Safety Car and Safety Car period meant that Ferrari were caught out and could only salvage a podium finish with Leclerc.
