Like the Drag Reduction System (DRS) in Formula 1, the effectiveness of Attack Mode tends to vary from circuit to circuit in Formula E. In Jakarta, it didn’t appear to make overtaking all that much easier – which we’d argue is a good thing – but it had its use in either allowing a driver to close in on a rival running ahead or as a means of defence.
Evans took an offset Attack Mode strategy in comparison to the pair of DS Techeetah drivers, running off line to pick up the power boost later on both occasions. When Vergne claimed his second dose, he lost the lead to Evans through the triggering zone, but quickly used the boost to pass his rival into the wide Turn One hairpin, which was the obvious place to overtake on this track. Evans waited a full 10 minutes later to take his second dose, 14 minutes from the finish, and crucially stayed ahead of da Costa as he did so.
The Jaguar closed in on Vergne’s DS Techeetah, but the power boost was all used up when, with six minutes left on the clock, Evans appeared to surprise the leader by braking later into Turn Seven and slipping down the inside. Following added time in the wake of the race’s single safety car period, when Oliver Rowland’s Mahindra lost a wheel early on, Evans crossed the line for a narrow win from Vergne, with Venturi’s Edoardo Mortara shadowing the pair closely in third. All three finished with zero per cent read-outs on the energy they had left – which shows how fine the margins are on team and driver strategic accuracy in this complex and challenging series.
