0
The time taken in seconds for the gearbox of the E20 to change gear (drive is never lost during the gearshift).

0.1
How much faster in seconds the E20 goes each lap due to the reducing weight as the car burns fuel (not accounting for tyre degradation).

1.6
The time in seconds for the E20 to decelerate from 100 km/h to standstill.

3.0
The average time for the pit crew to change all four wheels and tyres at a pitstop.

4.9
How many seconds it takes for the E20 to reach 200 km/h from standstill.

5
The number of consecutive races each gearbox must survive before it can be changed without suffering a five-place grid penalty.

6
How many hours it takes for a complete rebuild of the car at the track with 12 mechanics (assuming sub-assembly is already complete). From scratch at the factory it would take 150 people seven days.

6.67
The number of seconds per lap that the KERS electric motor can be activated at full power.

7
The number of gears in the E20’s gearbox.

8
The number of engines allocated to each driver in 2012.

10
The weight of a Pirelli front tyre in kilograms.

18.5
In psi, this is the average pressure for an F1 tyre.

30
The weight of a driver’s head and helmet in kilograms during maximum braking of 4.5G (the same as a heavy suitcase).

42
The number of revolutions per second by a tyre when the E20 is travelling at 300 km/h.

60
The amount of water dispersed in litres per second by a wet Pirelli tyre travelling at 300 km/h.

87.75
The impact energy in kilojoules that must be withstood by the nose of the car when it is crash tested by the FIA. This is the same amount of energy as would be required to stop a 4 tonne elephant moving towards you at 25km/h.

90
The operating temperature in degrees Celsius of each Pirelli tyre.

130
Measured in decibels, this is how loud the RS27-2012 engine is at full revs.

400
The amount of braking energy in kilojoules that the KERS generator can place into the KERS battery in a single lap.

500
The temperature in degrees Celsius reached by the clutch during a race.

640
The minimum weight of the car in kilograms

900
The temperature in degrees Celsius of the exhaust gases when the car is on full throttle.

1,100
In degrees Celsius, this is the temperature a brake disc can reach during the race.

1,500
This is the total number of moving parts in each RS27-2012 V8 engine.

2,500
The number of gear changes the drivers have to make during an average Grand Prix.

4,000
The total number of parts that make up each RS27-2012 V8 engine.

11,000
The number of technical drawings produced by the time of the E20 car build (28% more than any previous car).

10,000
The number of aero parts tested annually in the wind tunnel.

30,000
The number of individual parts that make up each E20.

250,000
The amount of man hours that have gone into the design of the E20.
