Spark-Renault SRT 01E Next Generation F1 car

The Spark Renault SRT 01E is an electric formula race car designed for the inaugural season of formula E,in 2014-15. The car is the result of a 10 month collaboration between spark racing technology,McLaren Electric system,Williums Advance Engineering, Dallara And Renault.

Development of the car started in September 2012. Lucas di Grassi was appointed as official test driver, demonstrating the prototype, the Formula EF01(built in 2010).The Formulec EF01 featured a chassis constructed by Mercedes GP and motors built by siemence. The car was used for the official promotion video and for demonstrations in host cities.

Design

• Aerodynamics optimized 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
• 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: 5,000 mm (197 in) (max)
• Overall width: 1,800 mm (71 in) (max)
• Overall height: 1,250 mm (49 in) (max)
• Track width: 1,300 mm (51 in) (min)
• Ride Height: 75 mm (3 in) (max)
• Overall weight (inc driver): 888 kg (1,958 lb) (min) // Batteries alone 320 kg (705 lb)

➥According to the regulations, the Formula E cars can be charged during practice, qualifying, the race and some other specified moments during a raceweekend.Drayson Racing and its technical partner QualcommHALO are developing a way to  Wirelessly Charge the car. The wireless electric vehicle charging (WEVC) system uses a pad under a parking space to charge the car. The system is tested on the electric Drayson B12/69EV, a modified version of the Lola Bo8/60.
