On YouTube, Rich Rebuilds converted an old T-bucket hot rod to electric using the drive components of a wrecked Zero motorcycle. The motor is surprisingly small but the performance was pretty good nonetheless.

The Smart roadsters were even smaller, so keeping component sizes down is a win for this project.

i mean Aerodynamic improovments :P

And how i should use a heavy and complex hybrid with a lot of parts they could wear, when i could get a maintance free System with 300km+ and over 150kW on the Rearaxle? :P

The Zero Components are to weak and brittle for this job. I would drive 200000km+ without touch the drivesystem.

I was looking for confirmation.

Here's mine:

(The one on the right.

) A Toyota HSD part, 98lb/68hp. I have a donor vehicle but no current prospect of getting the two of them together.

I'm not really sold, because it's a single motor/open diff unit. Later models have twin motors and limited slip in software, with 80hp, so far as I know.

Hi,

the new Lithium Cells should arrive in a few days. The new ones has ober 255Wh/kg energy density and a continuous currect of 3C (peak 5C). So i could pump over 125kW peak out of this tiny 95kg Batterypack.

Many many changes in my project in the last months! Other cells, other Motor, other BMS and so on...
I dissamble the car actually and look where i can save up some kg.

Servus,

My previous job did not allow me to make any significant progress on my project. Since I have come more and more into the field "EV", I have now decided to make myself independent again. The project "Smart Roadster" is thus approached with new energy and buget. The goal is to participate in the "EcoGP" this summer and also to win!
Pictures of the stand will be available in the next 2 weeks. I am currently moving into a new factory building.
