Kind of cool, but small volume
I hope it really has the acceleration they claim. Electric motors can certainly put out more torque than gas engines can, so it will be nice to see a car that takes advantage of this to leave the dinosaur burners in the dust on the drag strip.
I wonder what cells are being used, I'd assume some type of LiFePO4 to get the fast recharge time. Actually could be some higher C rate version of NCA cells too. No mention of range that I can find, but I'd guess it should be able to get around 150 miles or so.
Range: 100 miles
Body is a ~$20k Daytona Coupe kit. Well it sounds more challenging to develop EV from it, Tesla started with Lotus glider.
Wonder how much homologation costed them.

Opps, looks like they used this body: CSX9000
Yes but you could use the FFR kit and probably get similar results for a lot less money.
Has anybody noticed that there are no side mirrors!
Have they forgotten them?
There must be a reason?
IMO it's only an ad. The real model will have the side mirrors for sure.
I met with these guys a few months ago (under non-disclosure). They are a real deal Silicon Valley startup striving to build a high quality product. I expect that they will deliver on their promises.
There is more info on the company and product in the Pebble Beach Concours reveal press release.
Does this car fall under conversion?
And very high price, over half a million dollars, and not designed from the ground up as an EV. So in the EV revolution big picture this car is a footnote.
Unless their goal is to use it as a proof-of-concept for their innovative EV supercar/track car drivetrain.
I found this electric FFR Roadster build last night: Wayne's 2010 FFR Mk4
Electric Mk4 - FFCars.com : Factory Five Racing Discussion Forum
He is running a DC drivetrain with P85 levels of power (1350A @ 240V = 324kW = 435hp), but half the weight.
Lots of videos on his youtube channel: https://www.youtube.com/channel/UCL42VFYP-_7SCH-Xkuhbv4g
There are also a few electric 818 builds:

I haven't seen an electric Factory Five Coupe (yet)
Yes you have, in the video I posted :wink:
Oh, you mean that video that I watched and then quoted? Nevermind... :biggrin:
I'm curious to learn more about their battery pack and charging system.
So far I know:
30 kWh size battery, 100 mile range max (likely lower range in real world driving)
740-volt lithium-ion battery pack
can fully charge in 30 minutes via DC fast charger
At first I was surprised by the 30-minute charge number. Then I found out its only a 30kW sized battery pack.
single gear transmission , limited to 120mph
twin sequential axial flux electric motors, 500 hp & 1000 lb-ft of torque
only around 100 vehicles to be made. price tag $529k
So a 30 kW battery pack. I guess it'll be able to use the CHaDEMO fast charger for that 30 minute charge. Seems reasonable. Certainly Tesla's tech can charge more than 30kW in 30 minutes so it's not like Renovo invented anything new here with regards to fast charging.
I wonder why kind of cooling system they have in place to address concerns about temps when fast charging or sitting fully charged in the Arizona type heat.
What's the original source for the pack voltage at 740V?
If that's accurate, then fast charging is not compatible with CHAdeMO or SAE DC -- those specifications top out at 500VDC and 600VDC, respectively.

Don’t know if there’s anything new. Except maybe for the hairstyle of the CEO. :wink:
The range on this EV is pathetic considering the extraordinary price.
