The shakedown was used to evaluate the performance of the new battery, with the car completing over 400 km, but running without the Halo driver protection device, or fully installed bodywork.[10] In October 2017, the SRT05e successfully completed its first endurance tests held across three days, at the Monteblanco Circuit in Spain, once again, without the halo cockpit protection system, but with the full bodywork of the car installed.[11] On 1 December 2017, the FIA, as well as Formula E Holdings announced via Press Release, that they would renew their exclusive partnership with Michelin to supply tyres for the Championship until 2021.[2] On 6 March 2018, the SRT05e was launched at the Geneva International Motor show by FIA President Jean Todt, as well as Formula E Holdings CEO Alejandro Agag.The track was modified to include two specially-inserted temporary chicanes, on the front and back straight, with lap times estimated to be around the 1:01 mark.
