F1 By Numbers

The season is over, but that doesn't mean we can't marvel at the Silver Arrow's astonishing advances in efficiency technology over the years.

1. The weight of the battery has been reduced by 81% in just nine years, while its energy density has doubled.

2. The kinetic energy recovery system (KERS) now boasts 95% efficiency when storing the energy generated during a race in the battery system. In 2007, the system claimed just 39% efficiency. Despite all the intelligent software solutions, however, it is the driver who ultimately decides – using a switch on the steering wheel – when additional electric power should be deployed.

3. KERS weighed 107kg in 2007. The latest iteration weighs just 20kg. 

4. A Silver Arrow now regenerates enough energy during an F1 race to meet the needs of an average family home for 24 hours.

5. The processor inside the race car carries out more than 43 trillion calculations over the distance of a single race.

6. At a flow volume rate of 100kg of fuel per hour, the power unit pumps out 1 240kW of performance.

7. Exhaust gases from the 1.6-litre V6 combustion engine exceed 1 000 °C. They drive a turbine that is connected to a compressor. In between, the MGU-H (H = Heat) hybrid unit sources its energy from the exhaust gases produced by the engine. This energy is stored in the battery along with the electricity generated under braking by the MGU-K (K = Kinetics) unit.

8. Billions of calculations are carried out by the power unit every second during a race. Its processors are roughly 20 times more powerful than those of a conventional car.

9. The engine reaches temperatures of 2 600 °C during a race and performs more than 46 000 combustion events per lap.

10. The MGU-H generator can push the turbo's compressor unit to a speed of 100 000 revs per minute.

11. The compressor in an F1 engine pumps air into the combustion chambers, compressing the intake air to around five times that of atmospheric pressure.

What the Hypercar Means for the Future of Mobility

When the S 400 BlueHybrid – the first Mercedes-Benz foray into hybrid passenger cars – hit the streets nine years ago, no one could imagine the same technology would one day be repurposed to push the limits of performance.
