The Spark-Renault SRT_01E is an electric racing car designed for the FIA Formula E championship . It was the standard racing car for the 2014/15 FIA Formula E Championship , which was held on street circuits around the world from September 13, 2014 .
development
The Spark-Renault SRT_01E is a joint production of various manufacturers under the Spark Racing Technology merger under the direction of Frédéric Vasseur , a co-founder of ART Grand Prix . The name is made up of the abbreviation of the company name SRT , the project number 01 and an E for "electric".
Dallara developed the chassis of the racing car, McLaren Electronic Systems , a subsidiary of the McLaren Group , the electric motor , Renault the design and Williams Advanced Engineering the battery technology.
Technology and performance
The aluminum and carbon (CFRP) chassis has a sandwich honeycomb core construction . During the construction, care was taken to ensure that composite materials are used, but only a limited amount of CFRP in order to keep the manufacturing price low. The safety standards ( e.g. crash test , head and neck support , roll bars and an electronically operated fire extinguishing system ) correspond to those of the Formula 1 World Championship .
According to the regulations, the weight of the vehicle including the driver must not be less than 888 kg, and the weight of the battery and Rechargeable Energy Storage System (RESS) must not exceed 200 kg. The 26 kg electric motor, which is a further developed version of the electric motor from the McLaren P1 , drives the rear wheels and has a maximum output of 200 kW at a nominal voltage of 610 volts . The RESS has a similar structure to the Motor-Generator-Unit-Kinetic (ERS-K) of the ERS of Formula 1 , the total energy is limited to 28 kWh per vehicle and race.
The vehicle has a braking system from the British manufacturer Alcon , the brake calipers are made of aluminum, the brake discs are made of carbon. Similar to Formula 1, the wheels of the Spark-Renault SRT_01E are anchored with steel cables so that the wheels do not come off the vehicle in the event of an accident. The wheel suspension consists of steel double wishbones with thrust struts and torsion bar springs on the front axle. In addition to the ground clearance, the toe, camber , stabilizers and shock absorbers from Koni are also adjustable. The rack and pinion steering is servo-assisted .
Equipped with a sequential five-speed gearbox from Hewland , the racing car reaches a (governed) top speed of 225 km / h and accelerates from 0 to 100 km / h in three seconds. Shifting takes place via paddles on the steering wheel, the gear ratio cannot be changed.
The supplier of the 18-inch all-weather tires mounted on magnesium rims from OZ Racing is the unit manufacturer Michelin . The tire width is 260 mm on the front and 305 mm on the rear axle.
After several suspension breaks during test drives and in the first races, Spark Racing Technology announced that it would start using reinforced suspensions from the Miami ePrix 2015 .
From the 2015/16 season onwards , eight designers were given the opportunity to further develop the drive (engine, transmission, inverter and cooling system) and the rear suspension. Spark said that it would also make changes to the suspension and brakes on the vehicle. All designers use their vehicle, based on the Spark-Renault SRT_01E, under a different name.
A new body kit was planned for the vehicles for the 2016/17 season . The changes, however, were limited to a new front wing, the look of which was more futuristic and should make the vehicle design stand out even further from other formula vehicles. Since the end plates were now attached to the vehicle nose with two struts, the wing was also more stable. In the first two Formula E seasons it happened several times that the vehicles lost the end plates of the front wing after being touched.
Production and Price
42 vehicles were produced for the 2014/15 season and made available to the teams at a unit price of 350,000 euros.
For the season 2018/19 was Spark SRT_05e announced as successor.
