This Is How A Formula E Cars Works? – Video
Ever wondered how the electric Formula E cars work? We show you how each component works to provide power for the motorsport cars.
Formula E Car Specs:
Design
- Aerodynamics optimised to facilitate overtaking
- High ride height sensitivity and wide range of suspension set up possibilities to tackle the city centre streets
- Cost effectiveness
- Compliant to FIA safety regulations
Technology
- Use of latest technology, pushing the boundaries for the future
- Compromise between performance and cost effectiveness wherever possible
- Extensive use of composite materials but limited usage of the most expensive carbon fibres
Dimensions
- Overall length: 5000mm (max)
- Overall width: 1800mm (max)
- Overall height: 1250mm (max)
- Track width: 1300mm (min)
- Ride Height: 75mm (max)
- Minimum weight (inc driver): 888kg (batteries 320kg)
Power
- Maximum power: 200kw, equivalent to 270bhp
- Race mode (power-saving): 170kw, equivalent to 228bhp
- FanBoost (race-only): The three winning FanBoost drivers each receive an extra 100kJ of energy to be used in a power window between 180kW and 200kW
Maximum power will be available during practice and qualifying sessions. During races, power-saving mode will apply with the FanBoost system temporarily allowing maximum power for a limited time of 5 secs per car.
The amount of energy that can be delivered to the MGU by the RESS is limited to 28kwh. This will be permanently monitored by the FIA.
Performance
- Acceleration: 0 – 100 km/h (0-62mph) in 3 secs
- Maximum speed: 225 km/h (140mph)
Power unit
- MGU by McLaren
- Maximum of two MGU’s allowed
- MGU’s must be linked only to the rear axle
- The use of traction control is forbidden
Traction battery
- The traction battery is a Rechargeable Energy Storage System (RESS) and supplies electric energy to the Power Circuit and thus to the traction motor. Any onboard battery electrically connected to the Power Circuit is considered to be an integral part of the vehicle’s traction battery
RESS
- A Rechargeable Energy Storage System (RESS) is a system that is designed to propel the car via the electric motor. In order to comply they must be:
– FIA Standard
– The maximum weight of the Battery Cells and/or Capacitor of the RESS must not be higher than 200kgs
– All Battery Cells must be certified to UN Transportation Standards as a minimum requirement
Chassis
- Chassis / Survival cell – Carbon/aluminium honeycomb structure made by Dallara
- Front and rear wing – Carbon structures and Aero styling by Dallara
- Bodywork – Carbon – Kevlar honeycomb structures made by Dallara
Gearbox
- Hewland paddle-shift five-speed sequential gearbox
- Fixed gear ratios to reduce costs
Brakes
- Standard two separate Hydraulic systems, operated by the same pedal
- Brake material is free choice
- Calipers; the section of each caliper piston must be circular
The body of the callipers must be made from aluminium alloy
Wheels & tyres
- Bespoke 18″ treaded Michelin tyres for use on both wet and dry conditions/surfaces
- Championship specific wheel dimensions
- O.Z. Racing Magnesium rims. Max width front – 260mm / rear 305mm. Max Diameter – front 650mm / rear 690mm
Electronics
- McLaren Electronics ECU/GCU including data logging system
- Power supply management unit
- CAN data acquisition pre-equipment
- FIA Marshalling system
- Beacon receiver
- Telemetry is not permitted
Suspension
- Double steel wishbones, pushrod operated, twin dampers and torsion bars suspension (front) and spring suspension (rear)
- Adjustable ride height, camber and toe
- Two way (front) / Four way (rear) adjustable Koni dampers
- Adjustable anti-roll bar (front/rear)
Steering system
- Non assisted rack and pinion steering system (power assistance is allowed)
- Steering wheel with dashboard, marshalling display, gear change and clutch paddles
Safety
- FIA safety standards including: front, side, rear and steering column impact tests
- Front and rear roll hoop, impact structures and monocoque push tests
- Anti-intrusion survival cell protection panels
- Wheel retainer safety cables
- Extinguisher system (electronically operated)
