War of attrition
The race at the Parque O’Higgins Circuit produced no fewer than eight DNFs in 2018/19, which - at the time - set a new Formula E record; since equalled in Hong Kong in March 2019.
There were just 14 classified finishers - perilously close to the series' record low of 13 both at the 2015 Monaco E-Prix and the race around Battersea Park in London, 2016.
Six didn't make it this time around, with Andre Lotterer disqualified for exceeding power limits in his TAG Heuer Porsche, whilst Edoardo Mortara (ROKiT Venturi Racing), Brendon Hartley (Geox Dragon), Neel Jani (TAG Heuer Porsche), Jerome D'Ambrosio (Mahindra Racing) and Jean-Eric Vergne - already his second none-finish of the season - failed to make the chequered flag.
Evans: 'Glitch left me blind!'
Panasonic Jaguar Racing's Mitch Evans said the team had "work to do" after a software problem saw what should have been a clear lights-to-flag victory slip away, leaving the New Zealander to scrabble home third.
Evans had stormed qualifying to take a maiden Julius Baer Pole Position and bag three points but it could have been so much more. He looked commanding in the race, too, until BMW i Andretti Motorsport's Max Guenther slipped past in a perfectly executed move at just over the half-way stage.
"The race sort of slipped from our hands, it was a bit of a strange one," admitted Evans post-race. "Looking at the positives, we got some good points and a podium after having a bad start of the season in Diriyah, so I was happy with that.

"Starting from pole, I wanted to walk away with a win, but we still have work to do. From the start, we had software problems that we had to deal with. I'd never experienced them before.
"I over-consumed energy because I wasn't getting any information and it left me blind with no guidance. It was extremely difficult to manage the race. Equally, it could have been a lot worse. I was happy with the result but it was bittersweet."
Max's 'dream' win
A year on since BMW's driver Max Guenther failed to finish the 2019 Santiago E-Prix driving for his former team Geox Dragon, he stormed to victory in a perfectly executed race - clinching his maiden win in Formula E with a daring now or never move on the final lap.
It was some battle with Antonio Felix da Costa in the DS Techeetah, who was chasing his first race win with the team. Da Costa moved beyond Evans' ailing Jaguar and went about hunting Guenther who had climbed to the front of the pack past Mahindra Racing's Pascal Wehrlein earlier in the encounter.
Holding out, Guenther maintained the lead with less than three minutes left on the clock. With both cars entering Turn 10 together, Da Costa forced the BMW driver wide, creating the space for a move up the inside to snatch the lead at the last.
With less than 60 seconds to run, Guenther wouldn't be denied and was back on the attack, right onto Da Costa's diffuser. Both had the same level of energy to play with and in a straight fight, the BMW man stormed by Da Costa into Turn 9, regaining a hard-earned lead, where he stayed.

"It's a dream come true," said Guenther after the chequered flag. "For all of us it was about managing the race in hot conditions and it was a straight fight for the win.
"Having not made a great start on the dirty side of the track, which cost me a position, we used the ATTACK MODES very cleverly. That allowed me to take the lead. In that heat, it was also important to keep an eye on the temperature of the batteries. We did that really well.
"On the final lap, Antonio had to coast a little earlier than me on the straight. I thought to myself ‘now or never’ and went for the overtake. Fortunately, it came off!"
Da Costa on the rostrum
He didn't hold on for the win, with Guenther stealing in at the last, but DS Techeetah man Antonio Felix da Costa secured the team's best result of the season with second place in Santiago.
After a torrid start to the campaign for both Da Costa and team-mate Jean-Eric Vergne - the defending champion - the Portugese provided a crumb of comfort, though JEV once again couldn't make the finish and retired from the running at Parque O'Higgins.
“It was great to have a first podium and to fight for a win with my new team already when we are only three races in," he said post-race. "We’ve still got some work to do because that should have been our win today but we’re still a new team and we’ve still got some things to get on top of.
"We made a mistake with the energy and I thought we were good to go, so I overtook for the lead of the race but had to slow down pretty quickly after to manage the temperature. It was better to finish second and get the points than not finishing the race at all.”
