At its 30th anniversary at the Goodwood Festival of Speed (FOS), Porsche unveiled its Vision 357 Speedster concept. The all-electric retro-looking speedster is a sister model to the Porsche Vision 357, “a nod to the first Porsche model line.”
Porsche revealed its Vision 357 in January, 75 years after the 356 No. 1 Roadster became the first vehicle to bear the Porsche name.
The automaker calls the 356 “the dream of Ferry Porsche” and “the birth of the sports car brand.” Porsche’s Vision 357 brings the design into the modern day.
The Style Porsche Team was tasked with designing a sports car that Ferry Porsche would create if he was alive right now. In other words, “What would the dream of a sports car of Ferry Porsche might look like today?”
At its 30th anniversary at the Goodwood FOS, Porsche showed off a convertible version of the Vision 357. Michael Mauer, vice president of Style Porsche, said:
The Porsche Vision 357 is a nod to the first Porsche model line, Ferry Porsche’s dream sports car. And since the 356 has burned itself into the collective brand memory as both a convertible and a coupé, the same logic applies to the concept car: there can only be two.
Mauer continued to say that the new Speedster EV “demonstrates that even with fresh design genes, the Porshe DNA shines through.”
Meet the all-electric Porsche Vision 357 Speedster
The all-electric Vision 357 speedster is designed in tribute to the 356 but is based on the 718 GT4 e-Performance. As such, the electric motors and battery tech come from the Mission R, while the chassis is from the 718 GT4 Clubsport.
Although Porsche doesn’t share performance specs, we expect it would deliver the same over 1,000 hp (800 kW) in qualifying mode. As such, the Vision 357 Speedster should achieve 0 to 62 mph (0 to 100 km/h) in under 2.5 seconds.
On the retro-inspired exterior, the model features a large “75,” in homage to the anniversary of the 356 Number 1 Roadster, with the years “1948” and “2023.”
The two grey tones are inspired by historic motorsport forerunners, which is complemented by Miami blue on the wrap-around front bonnet. The vertical grill pattern in the rear is another nod to Porsche’s first model.
In addition, Cameras have replaced the exterior mirrors featuring a new, aerodynamically optimized shape “reminiscent of wings.”
The interior is reduced to essentials and is “fully tailored to the driver.” This includes a low-slung sporty seat position, a racing steering wheel, and an instrument cluster that “sits atop the steering column as a transparent surface.”
The entire dashboard is a carbon-weave finish, while the conventional glove box has been replaced with Miami blue straps in the upper right section to save weight.
Porsche says the Vision 357 Speedster was the “highlight at Goodwood.” After debuting the model at the event, the design study will be displayed at the 2023 Rennsport Reunion at the end of September.

After years of waiting and many falsestarts, 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.
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.
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.
