The futuristic Gen2, or second-generation, cars that will debut in Saudi Arabia on Dec. 15 now boast double the battery range.
That means drivers can do a full distance without having to pit, jump out and change vehicles midway through a race, as they have had to up to now.
“Now people are coming, assuming that this is a long-term venture that is going to be playing a really huge role in the motorsports industry and in the car industry,” added Agag.
“And we cannot fail. We have new manufacturers, new sponsors. It’s great, but it also means more responsibility.”
The technological step-up will lend the series greater credibility and burnish its credentials as a test bed for electric car manufacturers. Currently, those manufacturers include Audi, Jaguar, Nissan and Citroen/DS, with Porsche and Mercedes-Benz set to join in 2019 for season six.
The new cars are still far from Formula 1 pace, with the Gen2 accelerating from 0-62 mph in 2.8 seconds compared to less than 2 for an F1 car.
The top speed of 174 mph compares to Formula 1’s record of 231, but the gap is closing.
“Electric cars are going to go faster and faster,” said Agag. “I see us going now towards smaller batteries with the same amount of power, and ultra-fast charging so maybe one or two pitstops during the race in generation three.
“This will mean less weight, even more power, so a lot more performance.
“And I think generation four or five can be at the same level as the Formula 1 cars today.”
Ultimately, he said, the time could also come when Formula E was ready to break away from being purely a city-based street circuit series, where speeds are limited by track characteristics.
“I think when the performance is there, we need to provide a platform, a laboratory for these electric cars to go to the limit,” he said. “At the same time racing in cities is part of our DNA.
“I see maybe a hybrid situation in which we keep some races in the cities but we do maybe three, four, five at racetracks to allow these cars really to express themselves, to show their level of performance.”
Agag stated recently that he saw Formula 1 starting to feel the heat from Formula E in the next five years, with the electric series destined to become “the main motorsport in the world.”
Speaking to Reuters, he said his series had reason to feel confident but there was plenty of room for both championships.
“We are not competitors with Formula 1 and we are still always big fans of Formula 1. But obviously the fact that we are still here and now probably in the best moment of our history, of course we feel more confident,” he said.
“I don’t think Formula 1 should be worried at all about Formula E.
“I think our rival is tennis, golf, football. Other sports. The better Formula 1 does, the better Formula E will do. And vice-versa.”
Season Five will also feature a new ‘attack mode’ or ‘hyperboost’, introducing a new level of strategy with drivers going off the racing line in certain sectors to collect more power — as in the video game Mario Kart.
“I think the cars, just the look of the new cars is incredible, but the sound of the new cars is a lot more exciting,” said Agag, summing up the draw of the new season.
“The attack mode I think is going to be super-fun to watch…we’ve just seen a glimpse of it in Valencia during the test and it looked amazing, but I’m so excited to see this thing in action.
“There will be a little bit of chaos in the first race but that’s OK.”
