All You Need To Know About The SF90 (2019 Ferrari F1 Car)
With the Ferrari 2019 Car Unveiling this morning, here are all the details you need to know about the SF90 – for those who love the technical side of Formula 1 cars, you’re going to love this!
The SF90 is also known internally by Scuderia Ferrari as 670 – this is the 65th single-seater which has been built by Ferrari to compete in the Formula 1 World Championship.
As we all know, there have been new regulations placed and this means, as with all teams, we’ll be seeing quite a few changes being made compared to the 2018 F1 cars.
Take a look at the image above and the images further below – you’ll notice one of the most obvious changes, being those to the front and rear wings – the front is wider with simpler aerodynamic profiles whilst the rear wing is much wider and higher.
The bargeboards have been reduced in their height whilst the front brake duct design has been overall simplified.
One thing which is always key is the weight of the car – this has increased overall to 743 kilos and this includes the driver and his kit which must weigh a minimum of 80 kilos. The fuel allowance for the race has also increased from 105kg to 110kg.
Front Wing – 2019 Ferrari Car
The front wing is one of the most important components of the car – for every team. Not only does it produce downforce, it also conditions the quality of the airflow over the rear and this is a key factor when it comes to delivering effective aerodynamics to benefit the driver.
With the 2019 regulations – there was a requirement of simplification of the front wing – it’s width in turn has now increased to 2 metres which is exactly the same as the track of the car. The vertical elements at the extremities of the wing are no longer allowed and the geometry of the endplates has also been simplified – the purpose of these changes is to make the cars less sensitive to the outwash effect when following another car on-track.
Front Brake Ducts – 2019 Ferrari Car
The brake ducts are designed to cool the carbon brake discs which can reach temperatures of over a thousand degrees celsius!
Over the years, the shape of the front air ducts have become extremely sophisticated, evolving to also play an aerodynamic role and in 2019 this is another component which has been simplified due to the regulations.
Rear Wing – 2019 Ferrari Car
Just like the front wing – the rear wing has also been subject to change due to the rules for 2019. Now, it’s higher by 70 millimetres, increasing from 800 to 870mm and wider – increasing from 950 to 1050mm.
The end plates are 100mm longer and house the rear lights which consist of a pair of LED’s at the outer edges of the rear wing.
This is something similar and already adopted by the FIA for LMP1 and LMP2 prototype cars.
The rule changes also affect the Drag Reduction System (DRS) which is now more effective.
Weight – 2010 Ferrari Car
The 2019 Formula 1 regulations have seen the weight of the car increase by 10 kilos, going from 733kg to 743kg.
The fuel allowance for the race has also increased by 5kg and the minimum weight for a driver, including his equipment and seat is set at 80 kilos.
Any drivers who don’t reach the minimum weight – their cars must take on ballast which must be fitted in the cockpit area only.
(What’s Ballast? Ballast is material that is used to provide stability to a vehicle or structure.)
Engine Cover – 2019 Ferrari Car
The engine cover for the SF90 is considerably narrower in order to improve the overall car’s aero efficiency. The air intake now has a similar shape found on the 2016 car whilst the work on the fluid-dynamics inside the car means that is has the same level of cooling efficiency as the SF71H.
Whilst taking up less space overall.
Power Unit – 2019 Ferrari Car
A Formula 1 Power Unit consists of six components.
These are, the internal combustion engine – a 1.6 litre turbocharged V6; two motor generators, the MGU-K (Motor Generator Unit-Kinetic) and the MGU-H (Motor Generator Unit-Heat).
The MGU-K is derived directly from the system known as KERS which recovers kinetic energy under braking and stores that energy, up to a maximum of 4 MJ in the battery pack.
As for the MGU-H, it recovers thermal energy from the turbo. Another element is the battery pack, where the recovered energy is stored until it is released.
The sixth element is the electronic control unit.
For the 2019, Ferrari 064 Power Unit, both the thermal and mechanical efficiency has continued to develop and this was achieved working on engine combustion, energy recovery and fluids.
The Power Unit layout has been designed in symbiosis with the overall car design, while Energy Storage system reduced its weight and volume.
