The Spark-Renault SRT 01E is an all electric car, constructed by Dallara and Spark Racing Technologies.[1] The SRT_01E features an electric motor built by McLaren and batteries provided by Williams, and is the first car to be homologated by the FIA.[2]

Competitive HistoryEdit

The SRT_01E is the first car to be built for the championship, and will be raced by every team at every round in the inaugural 2014/15 season.[2] A total of fourty cars have been ordered for the ten teams, with the first shakedown for the entrants being held at Donington Park at the start of July.[2] The 2014 Beijing ePrix saw the SRT_01E make its competitive debut, with Lucas di Grassi taking the first win for the car on behalf of Audi Sport ABT.[3]

At the 2015 Buenos Aires ePrix, however, an inherent weakness in the SRT_01Es design came to fore, causing two almost identical retirements within a few laps of each other.[4] The rear suspension, which through the SRT_01E's unique design, has to support the weight of the batteries, gearbox and electrical systems, failed on both di Grassi and Karun Chandhok's cars during the race.[4] The components that failed have yet to be identified, but the rear suspension is expected to be modified on every car before the 2015 Miami ePrix.[4]

Development HistoryEdit

The SRT_01E began to be developed in 2012, with Frédéric Vasseur the original designer.[2] Spark (Vasseur's company) co-developed the chassis with Dallara, while McLaren Electronic Systems were asked to develop the electric motors and electrical equipment.[2] Williams Advanced Engineering were then asked to develop the batteries (capable of delivering up to 200kw (270bhp equivalent) for half an hour), with Renault installing and setting up the systems.[2]

Heidfeld Smash

A serious accident for Nick Heidfeld tests the SRT_01E's strength, with the German walking away unhurt.

Hewland were then asked to develop the sequential gearbox, which were fitted with fixed ratios to lower costs.[2] Michelin were named as the official tyre partner for the series, and hence produced a unique tyre for the SRT_01E.[2] The SRT_01E is capable of producing less than 80db of noise at full speed (ten more than the average petrol road car), a key feature of the car.[2] After the 2015 Buenos Aires ePrix, the rear suspension was redesigned to strengthen the car after several failures, the only major development on the car to date.[4]

Post 2015Edit

The SRT_01E becomes the testbed/basis for the eight new manufacturers set to enter the championship for the 2015/16 season.[5] These manufacturers will only be allowed to modify the powertrain, however, leaving Spark to update the rest of their design as they wish.[5] In April 2015, after three days of private testing with Gregoire Demoustier at the wheel, Spark announced that they would be modifying the brake and suspension systems before the new season started.[6]
