Ferrari revealed its 2023 F1 contender, the SF-23, at the company’s Fiorano track on St. Valentine’s Day. The Maranello challenger will make its racing debut at the Bahrain Grand Prix on March 5 with Charles Leclerc and Carlos Sainz Jr. taking turns.
The SF-23 uses the updated F1 car template that was revealed in July 2021. The template featured revised aerodynamics that helps the car retain downforce.
As you probably know, the F1 cars these days feature a hybrid powertrain that combines a 1.6-litre turbocharged V6 with MGU-K (kinetic energy recovery system) and MGU-H (heat energy recovery system) units. The K motor’s revs are limited to 50,000 rpm and its max power is limited to 120 kW or 163 metric hp. As for the V6, Ferrari has limited the revs to 15,000 rpm, and while it’s up to the manufacturers to put restrictions on the ICE revs, the combined power output cannot exceed 753 kW or 1,024 metric hp. If you do a quick math, the ICE produces just over 860 metric hp. With coolant, oil and driver, the SF-23 weighs 798 kg (1,759 lbs).
The K motor is mechanically connected to the crankshaft and is used to assist the ICE when deemed necessary, while the H motor is part of the turbocharger assembly and harvests the heat from the exhaust that would otherwise be wasted, and generates electricity that could be used for eliminating the turbo lag or to power the K motor.
