6 Amazing Facts about Formula E
1. Exceptional Speed For a Formula E Car:
The current top speed of a Formula E car is 225 km per hour or 140 miles per hour (which is also its average speed). However, the 2nd generation, according to FIA, is supposed to have increased powertrain performance as well was increased battery along with a brand new chassis, which will boost the performance of the Formula E car so that its top speed can exceed 300 km per hour or 186 miles per hour.
As mentioned above, the average speed of the Formula E car is the same as its top speed i.e. 225 km per hour/ 140 miles per hour, with an acceleration of 0 to 100 km per hour with a few seconds.
2. Striking Features That Make It Prix Worthy:
The acceleration of a Formula E car enables it to go from 0 to 100 km per hour within just 3 seconds, which is highly impressive considering the fact that this car runs on battery!
The overall weight of this car 896 kg (minimum), which includes the driver’s weight and the weight of the survival cell or chassis made from aluminum/carbon structure (honeycomb), bodywork made from Carbon, and rear and front wing made from aero styling and carbon structures. The batteries alone weigh 320 kg.
The Formula E car is comparatively much less noise producing than other cars and at full speed it produces sound that reaches only a high of 80 decibels (approximately), which is a bit higher than the normal road car (petrol) (70 decibel).
3. The Price Tag:
As of now the present cost of the Formula E car is €500,000. However, it has been brought to light that the cost of the car will be revised soon and will amount to €600,000 (total), which will be applicable in the upcoming 3 seasons. The cost is not supposed to go higher than €817,300, and the powertrains alone will cost €250,000. The halo device price is supposed to rise to €12,700, and the chassis will cost €299,600, while the spec battery will be priced at €200,000.
4. The Car Swiping Rule:
The battery technology has its limitations, which is why it is not possible for a Formula E car to offer high performance continuously after an hour on a single battery charge. Instead of swapping batteries, the FIA has made it mandatory for the drivers to switch cars. It is therefore compulsory for drivers to stop during every E-Prix, and then jump into another completely-charged car, which is kept ready and waiting in garage. The swapping needs to take place within the dedicated slot (of pitlane) or allocated garage under careful observation by FIA so that each and every safety belt and equipment gets fastened correctly.
5. Unbridled Strength And Power:
This electric car has a horsepower of 250 HP or more, while it offers almost instant torque (100%), which ensures faster acceleration of the car right from the start along with 17,500 rpm in terms of revs.
The reason why Formula E cars have gears is because gears make it possible for the motor to be highly efficient so that it can work along with the revs to reach the highest potential on chicanes, straights and bends. Gears also ensure effective maxing out on each point in any twisting street. However, shifting gears can cause the power to drop for some time (milliseconds), making the car lose its speed momentarily. This is the reason why Formula E cars use 1 to 3-speed gearboxes so that it can maximize efficiency all through the race without affecting the acceleration.
Using these gearboxes also allows the car to adjust with the varying torque characteristics of its electric motor. Earlier car models would focus on high speed with low torque, but these Formula E cars focus on high torque motors with lower speed, because of which the number of gears need not be high.
6. Time For Recharge:
A Formula E car works on electric power, which makes it necessary to control the distribution system so that it gets charged within 1 hour, both in a reliable and safe manner. However, charging can only take place during practice and in between each session, and not during the race as mandated by the FIA.
