The first batch of Formula E's Spark-Renault cars is on target to be delivered to teams on May 15.
The 10 teams that have signed up for the FIA's new electric single-seater championship will each receive their first Spark-Renault SRT_01E in just over a fortnight, with official testing beginning on July 3-4 at the series' Donington Park base.
Frederic Vasseur, head of the Spark firm that has designed the car for the initial series, confirmed that the scheduled delivery date of May 15 would be met.
"I think we'll work over the weekend for sure, but we'll be OK," he told AUTOSPORT.
The final test of the initial programme before teams become involved took place last week at Monteblanco in Spain, where Ho-Pin Tung drove alongside Jonathan Cochet and Antoine Leclerc.
Vasseur said testing had gone extremely smoothly, with an upgraded version of the car first tested by ex-Formula 1 driver Jarno Trulli showing good pace.
"We've done something like 4000kms of testing, which is something like three seasons of the Formula E championship, with no big issues," he said.
"We took a big step forward in the performance of the battery when Trulli tested the car with version two of the engine and battery.
"It's an exciting challenge and all the partners around the table have been really motivated by the project."
