Formula E’s new car is all-wheel drive and accelerates faster than F1
Formula E unveiled its new “Gen3 EVO” car, an update to the Gen3 car which debuted last season, ahead of the Monaco ePrix this weekend.
The new car will be used for next season, and is basically a mid-cycle update of the Gen3 car which has been in service for last and this season. The succeeding Gen4 car is not expected until 2027.
The Gen3 car was introduced as both lighter and more powerful as the previous generation car, with a lot of promises about how much quicker it could be in the races.
It also utilized some pretty unique design ideas. The biggest difference is the addition of a front motor, but this motor was only used for braking, and conversely, the rear friction brakes were entirely deleted and instead the rear axle is braked only by the rear motor using regenerative braking, for a total of 600kW regenerative braking power.
However, The Gen3 didn’t turn out to be all that much faster. This often happens with new racecars as teams get used to tuning and using them, but teams struggled to harness the extra power available to them.
At the same time, the series switched tire providers, and the new tires may have proven to be a limiting factor.
Now, the Gen3 car is hoping to fix both of these problems at once. Not only has Hankook provided stickier tires (with 5-10% more grip, and made of 35% recycled materials) which should help to harness some of the car’s additional power, Formula E has also taken the rather unique move (in the world of formula cars) of activating the Gen3 car’s front motor for thrust, not just regen – thus making its cars all-wheel drive.
The Gen3’s inclusion of a front motor left many thinking – ourselves included – that it would inevitably get activated not just for regen, but for power delivery.
There have been all-wheel drive single seater open wheel cars in the past, but it has only been tried a few times. Currently, other open-wheel single seaters (like F1, IndyCar and the like) are rear-wheel drive only.
AWD has been popular on road cars recently, because it enhances acceleration and drivability. And on EVs, it’s quite easy to add, because you can just slap a second motor on the other axle and run a few cables to it, rather than needing to run driveshafts and gearing mechanisms all through your car to transfer the power from a single combustion engine to two separate axles.
However, sportscar and racing enthusiasts have often preferred rear-wheel drive because it makes cars more squirrelly and difficult to control, showcasing driver skill more readily.
So Formula E is going to allow all-wheel drive only in certain situations. During qualifying duels, race starts, and during the activation of “attack mode,” a temporary 50kW power boost that each driver gets at certain points in the race.
One complaint about the Gen3 cars was that attack mode was hard to use, because the car felt like it couldn’t properly utilize that additional 50kW. By activating the front motor, this should give drivers a huge advantage – quicker acceleration through and out of corners is an enormous benefit.
While 0-60 numbers don’t matter a lot for a racecar – they’re only ever at 0mph at one point, at the start of the race, after all – acceleration is still important for exiting corners, and gives you a lasting benefit for the entire straight if you can get a better exit than another racer. And the Gen3 EVO boasts a truly impressive 0-60 number: 1.82 seconds.
This 0-60 time is 30% quicker than an F1 car and 36% quicker than the Gen3 car, thanks to that front motor helping pull the car forward with 4 contact patches instead of 2.
In addition, the design of the car has changed somewhat. The nose and front wing have been redesigned from the (perhaps overly) angular design of the original Gen3 car. Over the last season and a half, cars have struggled with front wing damage, so hopefully the new wing will be a little more durable.
All told, Formula E says that the new car could be 1-3 seconds faster per lap, depending on circuit and whether the AWD system is in use. This would be a pretty massive improvement as far as laptimes go, but we’ll have to see how it plays out when next season comes around.
Now, if only we could also see that 600kW mid-race charging they’ve been working on…
The new Gen3 EVO car will start seeing use next season, but if you want to see the current Gen3 car in action, you can watch it this weekend at the Monaco ePrix.
The race proper starts at 6am PDT, 9am EDT, 1pm UTC, and 3pm local Monaco time on Saturday April 27. In the US, all sessions other than the race will be available on the Roku channel, practice sessions will be on Formula E’s YouTube, and the race will be on CBS/CBS Sports Network.

After years of waiting and many false starts, Formula E is finally going to debut its mid-race charging system, which will give cars a quick boost of energy charging at a rate much faster than current road cars can.
For years now, we’ve been hearing about FIA plans to introduce charging stops to electric racing.
In gas car racing, some series allow mid-race fueling and some don’t. The World Endurance Championship, which runs the 24 Hours of Le Mans, obviously needs to fill up several times during the race. But Formula 1, which hosts shorter races, eliminated mid-race fueling in 2010.
Plans to bring mid-race charging to Formula E started in 2021, when the FIA started kicking around plans for an Electric GT racing series with 700kW charging.
But the FIA already had one electric racing series, Formula E, which had debuted in 2014. At the time, each driver had two cars, and would swap mid-race to a fresh car with new batteries.
Battery-swapping had been considered, but it would be too complicated to set up at temporary race facilities in city downtown areas, as many Formula E tracks are.
Then, in 2018, Formula E debuted a new “Gen 2” car which had a big enough battery not to need a charge mid-race, and later a “Gen 3” car in 2022, which had much stronger regenerative braking, capable of 600kW of braking power. Gen 3 also has an “Attack Mode” feature that lets cars unlock additional power for a short period each race, adding to strategy and mixing up the race order.
That 600kW charging ability could also be used for mid-race charging, so Formula E said that it was working on a system to allow for this. It announced that mid-race charging would come at some point in the 2023 season, but then pushed back those plans until 2024, and pushed them back again, this time with an uncertain date.
The issues involved building the charging system in temporary facilities and ensuring safety of the system (and of pit stops in general, which is always a concern when cars are driving rapidly near people). But after winter testing prior to this season, Formula E now says the system is ready to go.
So, once again, Formula E is ready to announce that mid-race charging is definitely, totally, positively, 100% certain at the upcoming Jeddah E-Prix, on February 14-15 in Jeddah, Saudi Arabia.
Formula E thinks that proving this high-power charging technology could help road cars to charge more quickly, which could have myriad benefits for electric cars in general.
The series is calling the system “Pit Boost,” and it will consist of a 34-second pit stop that provides around 10% additional charge to the cars (about 4kWh). While 10% isn’t a lot, 34 seconds is also not a lot of time. For comparison, one of the fastest-charging cars out there, the Ioniq 5, can charge from 10-80% in 18 minutes, which means 10% charge takes 2.5 minutes – five times as long as Formula E cars will manage the feat.
The stop will be mandatory for all drivers to take at some point in the race, and will mean new strategy options for drivers. Taking the stop means getting more energy, which means that your car won’t have to do as much energy saving to get to the end of the race – but it also means giving up your position on track, which can be hard to get back if you do it late in the race.
However, we’ve never seen it happen before, so it will be interesting to see what kind of strategic options develop.
If you’re interested in seeing how it turns out, tune in to the Jeddah E-Prix on February 14-15 to see what happens. It’s a doubleheader race weekend, with night races both on Saturday and Sunday, February 14-15, at 5pm UTC, 9am PST, 12pm EST, and 8pm local time. You can check out how to watch the race in your area by going to Formula E’s “Ways to Watch” section. In the US, Roku should be the most reliable way to watch.

JackRabbit, the maker of pint-sized electric microbikes, is back with a new product designed to quickly recharge their batteries from pure, uncut photons mainlined into an e-bike directly from the sun. In true independent charging form, the Solar Charging Kit from JackRabbit keeps riders rolling even when there’s not a convenient AC outlet in sight.
Unveiled this week, the Solar Charging Kit consists of a single folding solar panel and a tiny voltage converter that is configured to output 42.0V, which is the exact voltage required by JackRabbit’s little e-bike batteries. There’s also an added USB-A and a USB-C charging port for powering other devices in addition to charging JackRabbit batteries.
“This Solar Charging Kit plugs directly into your bike,” explained the company, “letting you recharge without needing an outlet, but with a speed comparable to the charger that comes with the OG/OG2 (42V, 2A).”
That would mean the panel outputs around 80W of solar power, which the company says can recharge its batteries in just three hours. That fairly quick recharging speed is helped by the fact that JackRabbit’s batteries are a mere 151 Wh, or around a third of the size of most e-bike batteries.
If that sounds small, then you’re right – it is. But JackRabbit is all about going micro, offering barely 25 lb rideables that are easy to store and bring on adventures, even when they aren’t actually being ridden.
With small batteries that fit under the 160Wh limit for many airlines in the US, the batteries can be quickly charged and taken to the widest number of locations. And for riders that want to go further than a single 10-mile (16-km) battery will allow, extra batteries are small enough to fit a pants pocket. The company also offers much larger Rangebuster batteries, though they won’t pass by TSA and make it onto an airplane in your personal item.
It sounds like the Solar Chargking Kit should be able to charge up JackRabbit’s large RangeBuster batteries, though likely in more than three hours.
The $349 Solar Charging Kit is a bit pricier than building something similar yourself, but it’s also safer and more convenient than hacking together your own battery charger since it’s designed to work with JackRabbit’s batteries right out of the box.
Technically it’s only inteded for JackRabbit’s micro e-bikes (themselves technically seated scooters, even if they look and feel more like a typical bike), but it’d probably work for just about any 36V e-bike that requires 42.0V to charge.
This isn’t the first time we’ve seen solar charging kits for electric bikes, and it’s a trend that is certainly appreciated by outdoors and camping enthusiasts, festival goers, or anyone who finds themself and their bike spending extended periods in the great, sunny outdoors.
