Ferrari hopes to wrestle for title with 2018 SF71H

  2017 Formula One Championship runners-up Ferrari have revealed their 2018 Challenger, the SF71H (the code name for the 669 project). The New Ferrari SF71H is the sixty fourth single-seater car designed and produced by the Prancing Horse. The SF71H will be transported to Barcelona’s Catalunya Circuit, for filming on Sunday, followed by the start of testing proper on Monday where Sebastien Vettel and Kimi Raikkonen will take turns driving the new car.

Rule changes introduced last season led to the introduction of significant aerodynamic modifications and wider tyres, all aimed at increasing performance. Therefore the new 2018 Ferrari F1 car has been created to make the most of the experience gained last year. Compared to 2017’s SF70H, the wheelbase has been changed slightly, with the side dimensions also revised along with the cooling system. The suspension follows the tried and tested practice of using push-rods at the front and pull-rods at the rear, however, their design has been updated based on experience gained during the first season running the wider tyres.

The most obvious element to catch the eye is the Halo, introduced for the 2018 season, designed to protect the cockpit area. After two years of on-track testing, it has now entered the rule book. It weighs around 7 Kg, plus fittings and this has only been partly compensated for with an increase of 5 Kg, from 728 to 733 – to the minimum car weight set in the 2018 regulations.

Ferrari SF71H’s Power Unit

The number of V6 engines that can be used over the course of the season, without incurring a penalty, continues to decrease, this year from 4 to 3. The same number applies to the turbo-compressor and MGU-H, the energy recovery system attached to the turbo, while only 2 MGU-K, the device that generates kinetic energy linked to the transmission; are allowed over the year. This also applies to the electronic control unit and the batteries.
