Chassis

Moulded carbon fibre and aluminium honeycomb composite monocoque, manufactured by Lotus F1 Team and designed for maximum strength with minimum weight. RS27-2012 V8 engine installed as a fully-stressed member.

Front Suspension

Carbon fibre top and bottom wishbones operate an inboard rocker via a pushrod system. This is connected to a torsion bar and damper units which are mounted inside the front of the monocoque. Aluminium uprights and OZ machined magnesium wheels.

Rear Suspension

Carbon fibre top and bottom wishbones with pull rod operated torsion springs and transverse-mounted damper units mounted in the top of the gearbox casing. Aluminium uprights and OZ machined magnesium wheels.

Transmission

Seven-speed semi-automatic titanium gearbox with reverse gear. “Quickshift” system in operation to maximise speed of gearshifts.

Fuel System

Kevlar-reinforced rubber fuel cell by ATL.

Cooling System

Separate oil and water radiators located in the car’s sidepods and cooled using airflow from the car’s forward motion.

Electrical

MES-Microsoft Standard Electronic Control Unit.

Braking System

Carbon discs and pads. Calipers by AP Racing.
Master cylinders by AP racing and Brembo.

Cockpit

Removable driver’s seat made of anatomically formed carbon composite, with six-point or eight-point harness seat belt. Steering wheel integrates gear change, clutch paddles, and rear wing adjuster.

KERS

Motor generator unit driving into front of engine with batteries as an energy store. Motor Generator supplied by Renault Sport F1. Electronic control unit by Magneti-Marelli.

0 – The time taken in seconds for the gearbox of the E21 to change gear (drive is never lost during the gearshift).

0.1 – How much faster in seconds the E21 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 E21 to decelerate from 100 km/h to standstill.

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

4.9 – How many seconds it takes for the E21 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 E21’s gearbox.

8 – The number of engines allocated to each driver in 2013.

10.2 – The weight of a Pirelli rear tyre in kilograms (including rim).

18.5 – In psi, this is the average pressure for a Formula 1 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 E21 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 RS27-2013 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 RS27-2013 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 RS27-2013 V8 engine.

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

11,000 – The number of technical drawings produced by the time of the E21 car build (28% more than any previous car).

30,000 – The number of individual parts that make up each E21.

250,000 – The amount of man hours that have gone into the design of the E21.
