The Smart 451 Fortwo Electric Drive (ED)

I have been getting a worrying amount of messages asking why there are no specific
pages, tick boxes or information about the electric drive version of the fortwo 451.

I'd like to go on record with the 2 answers that I have been sending back to the people who ask.


It's pretty much just me adding stuff to this site, 1 person. I have a job but it's not a super well
paid job so I just can't afford to own every smart car variant. Smart don't give me cars, I don't
get a discount, I have to buy them all just like everyone else.

If you want to donate a car to me, feel free but currently I've just bought a house and had a workshop built.
I have no money left. I'm living on Pot Noodles and drinking rain water.

So, unfortunately, I just can't afford to buy a smart fortwo ED just to please the 200 people who own
them. I'd love to own one, I really would but even if I did own one, it would lead to a 2nd issue.

Edit: I saved up and bought one locally for a very good price.


This is hard to explain without sounding like I'm treating you like a spaz, so I'm just going to treat you like a spaz.

Exactly what info do you want? What mods do you want to achieve?

The hand manual tells you a lot about the car and apart from the motor and batteries, IT'S THE SAME CAR!

If you want to change the panels, it's the same as the petrol model.
If you want to spray the headlights, it's the same as the petrol model.
If you want to lower the suspension, it's the same as the petrol model.
If you want to know what bulbs you need, it's the same as the petrol model.

What About The Motor And Batteries?

Yeah, what about them? 

Did you know that not all smart dealers are set up or trained to deal with the fortwo ED?
They have all of the equipment required to deal with the lithium ion batteries.

Remember that time you short circuited the battery on your petrol model and you got a bit
of a spark and maybe the fuse blew? Short circuit the drive battery on this and you are flying
through the air, maybe with less skin and fingers than before, possibly on fire or dead.

You are not trained to mess with these batteries, you have no reason to mess with these batteries,
there is nothing you can do with these batteries to make your car faster or go for longer.

The motor is a sealed unit that has no user serviceable parts. You have no reason to mess with the
motor and there is nothing you can do to the motor unit to make it go faster or make it more efficient.

All of the power, torque and efficiency settings are all software controlled, so until there are remaps
available for them, there is absolutely no reason to mess with your ED batteries and motor.

Searching For ED And EQ Specific Pages

The way our tag words work, searching for "ED" or "EQ" won't work very well.

It's because the search will even look at parts of tag words so searching for EQ will bring up pages tagged
with the word "sequential" because there's an EQ in the word. This is much worse for searching ED.

Even putting a space after ED won't help. So....

I have added a specific search term for the ED and EQ that will narrow down the results.

Do a search for ED. EQ. E.D or E.Q

The full stop is important.

There Must Be Some Differences

Yes, they are covered by your hand manual.
However, here is the fuse layout

What About Difference in the 451 Gen 2 & Gen 3?

This has got to stop, even Wikipedia has the 451 ED down as 2 generations.

The same design car CANNOT be 2 different generations.
If a car is revised, it is an update (internal) or facelift (external).

The 450 ED was generation 1 and was tested in 2007.
The 2009 451 ED was generation 2.
The 2011 451 ED was generation 2, mark 2.
The 2017 453 ED was generation 3

Just because the 2011 model had a motor and battery made by a different company and the ECU
had slightly updated software does not make it a different car. The petrol and diesel model of the
451 aren't classed as different generations of car but the have different engines, fuel and software.

So, stop doing it. I'm looking at you Americans.

And whilst I'm at it. If you buy a car in 2017, it CANNOT be a 2018 model.
I don't know why this bullshit has started in the US apart from to try and trick idiots into
thinking they are getting something better and more futuristic than they really are.
