With the support of EQpassion, Steinbauer developed a tuningkit for the smart EQ. I have been using the finished product since two weeks now and of course I would like to tell you how it handles.
Anyone who knows the 4th generation smart electric drive, knows that this little city runabout has already an incredible acceleration coming from the factory. Between 0 - 50 km/h, it's faster than almost everything that everyday life has to offer. And that despite the fact that it's performance is always limited. The built-in electric motor from Renault can achieve up to 81 kW, but is limited to 60 kW in the smart (68 kW for Brabus).

There are two versions of the tuning kit:
• More regenerative breaking & a boost to 95 PS (752,06 €; excl. vat)
• More regenerative breaking (541,97 €; excl. vat)

The tuningkit is exclusivly beeing sold through EQpassion and it's shop.

The tuning company promises 10 % more power, torque, more regenerative breaking and even a higher top speed. Enough reasons to try the big 95 PS kit out and test how the little rocket is performing with the upgrade. For that purpose I build it in my 100,000 km old smart EQ.

It is particularly pleasant that the kit can be installed non-destructively and without tools in 30 minutes. It can also be easily removed and everything can be restored to its original state, as no cables have to be cut or control units reprogrammed.

Hello.

I installed the Steinbauer performance module two days ago and I think it delivers even more HP, regenerative braking and torque than advertized...
Is it only in my head? I don't know, but the regenerative braking almost stops VERY fast, and the hand of the discharging/recharging gauge goes to the left extreme right away.
Which makes me wonder if by lifting my foot off the brake pedal instantly, it doesn't supply too much amperage to the HV battery, and if that juice is used a 100%.

Thank you :)

Especially if you are already 100% charged, is there still a regen slow down when you go down a hill?
It adds 50 % more regen to the existing curve. So if the smart is fully charged and won't regen, it's going to add 50 %, which is still nothing. As the smart gets more empty, it's still adding 50 % to it and therefor regenerates more and more. :)

Same method applies for the horse power, when the battery is getting close to being empty.

1 - My 453 is the older one an "ED" label, and no radar based regen, being a US model. How do these kits change the regen when I select "ECO" mode? (Do the Euro models have this switch too?)
Yes, is also works there. European models can simply turn the radar based regen off, which I have all the time. And yes, we've also got the eco button.

2 - On your EQpassion Blog - Tune the smart EQ and Twingo ZE to 95 PS and > 140 km/h or simply make it regenerate more page, what is the significance of the yellow line in your "Motor Power of the smart EQ" chart?
That's the torque.

Hello people.

Has anyone thought of installing an electrical switch on the power supply of the Steinbauer performance module in order to be able to activate/deactivate it without having to get out of the car and open the trunk etc?

Thank you :)

Yes there is.
I am talking about regen when the battery is not a 100% charged.
This may be confusing???

The question Jeb asked was “if you are already 100% charged is there still a regen slow down when you go down a hill?”

You answered “YES, when the battery IS NOT 100% charged.”

Shouldn’t the SIMPLE answer have been NO? 🤯

Has anyone tried it yet?
I haven't, but I talked to my contact a Steinbauer.

They recommend, that you don't switch while the smart is on, but before starting the smart, you can decided which mode you want.


Marginal, why would you want to turn the module off?
Because the pedal is way more direct, you could say sporty, when it's turned on. Which you may don't want to have all the time.

Exactly.

That is why I intend to make a manual disengagement of the module, using a switch and relay(s).
Meaning, one switch on the power supply of the module (it has four wires on the plug on top of it, two /the thickest ones/ of which are the PS, and the other two are the data ones) extended with a wire to the plastic on the steering column, and one (or two?) relays, preventing this switch to work if the ignition key is on the on position.

Thanks.

Quite so.

There are some cases in which the module is not needed.
Let's say someone is pulling the car on the road thus recharging the battery.
It wouldn't be easy for them to pull with the module connected.
That's only one of the reasons ...

I'd call such an on/off module function - a Turbo one :)

Of course not, but why not be ready for it?
MYTHBUSTERS SAYS, PROOF OF CONCEPT - have you done a 451 “road tow regen” ever?

Just curious speed, distance “tires a smoking’” to provide a net gain of XX miles?

Might be better served to carry a liter of PETROL in the back?
