The Formula E Gen3 cars, introduced in the 2022-2023 season, feature a significant upgrade in battery capacity. They utilize a 47 kWh battery that provides enough energy for a full race distance. This increased capacity, coupled with improved energy management systems, has allowed for longer races and more exciting competition.

Power Output: The Gen3 Formula E cars, introduced in the 2022-2023 season, boast a significant power upgrade compared to previous generations. They have a peak power output of 350 kW (approximately 470 horsepower). This power, combined with regenerative braking, enables these electric race cars to achieve impressive acceleration and top speeds.  
It’s worth noting that this power output can be further increased during Attack Mode, a strategic element in Formula E races where drivers can activate a temporary power boost.

Formula 1

Internal Combustion Engines:

An internal combustion engine (ICE) is a heat engine where the combustion of fuel occurs within a combustion chamber that is an integral part of the working fluid flow circuit.  
• Intake Stroke: A mixture of air and fuel is drawn into the cylinder.  
• Compression Stroke: The piston moves upward, compressing the air-fuel mixture.  
• Combustion Stroke: The spark plug ignites the compressed fuel-air mixture, causing a rapid expansion and pushing the piston downward.  
• Valves: Control the intake of air and fuel and the exhaust of combustion gases.  
• Spark Plug: Ignites the fuel-air mixture in the cylinder.  

Key Components

While internal combustion engines have been the dominant technology for decades, their environmental impact has led to the development of alternative power sources, such as electric vehicles. However, ICEs continue to be widely used and are constantly being improved to meet stricter emissions standards and increase efficiency.  

Hybrid Power Units: A hybrid power unit combines a traditional internal combustion engine (ICE) with one or more electric motors. This combination offers several benefits, including improved fuel efficiency, reduced emissions, and enhanced performance. Hybrid powertrains offer a balance between traditional internal combustion engines and fully electric vehicles. They provide improved fuel economy, reduced emissions, and a smoother, quieter driving experience.

Fuel and Fuel Flow: In Formula 1, fuel flow is strictly regulated to ensure fair competition and limit performance. The current regulations impose a maximum fuel flow rate of 100 kilograms per hour. This restriction significantly impacts the strategy and performance of teams, as they must carefully manage fuel consumption throughout the race

Power Output: While the exact power output of a Formula 1 car can vary depending on specific engine configurations and track conditions, it’s safe to say that modern F1 power units are capable of delivering over 1,000 horsepower. It’s important to note that the specific power output can fluctuate throughout a race, depending on factors like track temperature, altitude, and engine mode settings. However, the overall power and performance of a modern Formula 1 car are truly impressive.

Chassis and Aerodynamics

Formula E:
• Lightweight Chassis: Formula E cars are designed to be lightweight and energy-efficient.

Formula E:
Attack Mode: is a unique feature in Formula E that adds an extra layer of strategy and excitement to the races. It allows drivers to temporarily boost their car’s power output, giving them an advantage on the track. To activate Attack Mode, a driver must deliberately drive off the racing line and through a designated activation zone on the track. By doing so, they gain an extra 35kW of power, increasing the car’s total output. Additionally, there’s a limited amount of time for which Attack Mode can be activated during a race. This strategic element, combined with the unpredictable nature of electric racing, makes Formula E a thrilling spectacle for fans and a challenging environment for drivers.

FanBoost: is a unique feature in Formula E that allows fans to directly influence the outcome of a race. By voting for their favorite driver, fans can grant them an extra power boost during the race. Before each race, fans can vote for their favorite driver through the official Formula E app or website. The top three drivers with the most votes receive an extra power boost, typically around 100kW. Drivers can activate this power boost strategically during the race, giving them a temporary advantage over their rivals. FanBoost adds an element of fan engagement and unpredictability to Formula E races. It empowers fans to directly impact the outcome of the race, making the series more exciting and interactive.

Formula 1

Sprint Races: Introduced in 2021, the Sprint race format is a relatively new addition to Formula 1. Designed to add excitement and unpredictability to Grand Prix weekends, it involves a shorter, separate race held on Saturday. The Sprint race format has added a new dimension to Formula 1, providing fans with additional on-track action and strategic opportunities for teams. It has also had a significant impact on the championship battle, as drivers can gain valuable points

Pit Stops: Pit stops are a crucial strategic element in Formula 1. They allow teams to make essential changes to their cars, such as changing tires, refueling, and performing minor repairs, all in a matter of seconds. Over the course of a race, tires wear down due to friction and heat. Pit stops allow teams to change to fresh tires with better grip, improving car performance.
