Formula E’s most recent race winner believes that the series and the FIA have made a good initial call on technical changes that are set to be implemented for the new generation of cars in 2022.
Alexander Sims expects that Monday’s detail on what the FIA is asking for with the release of its Invitations to Tender documents will produce a new set of challenges.
The specification that chassis and battery suppliers to the Gen 3 project will work to includes a two-phase option of either 450 kW or 600 kW total regeneration capability on a front and rear powertrain design that does not have a rear mechanical braking system.
Sims, who took his first Formula E win for BMW i Andretti Motorsport in Saudi Arabia last month, believes that the new-look cars will bring significant new challenges for drivers and teams alike.
“Right at this moment I would say it is difficult to anticipate exactly how it’s all going to manifest itself in terms of overall driving characteristics,” said Sims.
“I’m sure it’s going to be bringing some very different challenges, although when you have regen only on the rear axle it still brakes pretty well.
“It’s not like you can really feel a huge difference between the motor slowing you down versus mechanical brakes, but at the moment I would suggest that it’s just going to bring it back towards more what a conventional single seater feels like.”
Sims pinpointed the battery capabilities and how it could manage the possibility of 600 kW regeneration should this option be pursued.
“I hope that they can find technical solutions for the higher regen option because at the moment we sometimes max out the rear regen on heavy braking zones,” he explained.
“Knowing that there’s going to be more energy to capture from the front axle and the rear axle, even if you match it, you get to approximately 500 kW of regen. I think 600 kW is hopefully feasible but it just depends whether the battery can deal with it, I guess.”
Sims also sounded caution against Formula E making too many sweeping changes as he believes that the overall package of the championship is in good health.
“They’ve got a great product as it is, yes there are certainly ways to improve it and keep it relevant but I think making the cars more efficient on track, reducing mechanical braking and having more regen and potentially some more power is a great thing,” he concluded.
