I really wanna do a VW CC to be honest...it has everything i could want in a car and also i can buy it with a salvage title and then use the parts for my current car. i have a black one and i know that i can get a lot of fun and pleasure out of driving it.....So lets say I go with that car..would that be alright to do and make it electric
Since you have one you can do some checking on space for batteries. Its best to not put them in the passenger compartment. Best under behind and up front around the motor. You'd then need to figure out your motor/controller setup and maybe a voltage range. That would need a reasonable sized motor. Mostly for torque. The AC-75 is an affordable motor. The curtis controller can be set to utilize an automatic by doing idle. You might call up HPEVS and run it by them to see what they think. They also have a dual AC-35 which if you have the room would be a kicker motor setup. Might consider dual motors stacked if possible. Would require a custom adaptor plate. But would give a kicker vehicle. There are a few dual stacked motor setups around.

You could use the adaptors and couple them with the AC-75 motors. Dual AC-75's :)
Alright so now that i know i am going to do the VW CC. you are saying a dual stack motor setup would be possible? again distance is more important than top speed but i wouldn't mind it a little fun as well and as for batteries i can place them in the trunk and in the front..what is LiFePo batteries and can i use that
I HAVE NARROWED MY CHOICES


So I have narrowed my choices to the following cars and then i can finally focus one the guts of the project so here goes...

Kia Optima


VW CC



BMW Gran coupe


Mercedes Benz CLS

Lovely cars!

But all of them will be massively under powered with an AC75 - 80hp

You will need twice that for a car of that class
alright so then that means I need to get you a bigger motor on a double stack em as someone mentioned in an earlier post correct

Yes
But it will still be marginal for a big luxury car
Or go DC where you CAN get decent power levels

Or go for one of the more powerful AC systems - Scott drive??
There are much more powerful AC systems out there but at the $20,000 level
and that's due to the weight of car correct....so either go DC or a big strong AC motor in order to push it...... ok cool that's the next thing i will look for.....budget is not so much a problem as i know that it will get a little expensive but I wan't to show the potential....that most people can go about 150 miles or so and be ok

Your goals are pretty ambitious. All four of those cars are starting out pretty heavy. If you somehow manage to not add any weight beyond the original curb weight you are looking at needing a pack size of somewhere around 60kwh. With a Warp 11 HV and 340volts of batteries (98 cells 314V nominal) you would need about 190 ah cells. So probably 200AH cells. And I am not sure you will get the range you want even with that but it will be in the neighborhood.

My gut feeling is that with this many batteries you will add around 500 lbs above the original and thus lose about 12% of your range due to the extra weight.

That is a lot of batteries! Not sure where you will put all of them.

Best Wishes!
I appreciate the input and swift response and also vast knowledge which is a period in what I know so I would need a lot of battery in order to put a car of that magnitude on to the road we just electric power and yeah my plans are pretty ambitious but i just want to see how far this could actually go I know a lot of people use old school cars and smaller two seater cars but I would just like to see someone tried to do something different and if it have to be me to try I'm okay with that but i just want to see somebody try
so.........taking the advice from you guys it appears as thought that it's going to be expensive to do one of the big cars.......so i will slim it down and do a smaller size car.....any suggestions or is this is it
I'd say do some research on make/models, make a guess on battery pack, motor and controller, then come back and let the experts work it over. This is not something you should rush into, so enjoy the holiday!

As always, if you have questions, this is the place. :)

Cheers!
Happy holidays to all as well as u can see I try to keep up with you replies pretty quick. I been trying to look over and see....my first choice was the VW cc and still wish I can have that one but I will look at other options
