  • Tune the smart EQ and Twingo ZE to 95 PS and > 140 km/h or simply make it regenerate more

    Some readers asked for it and now the time has finally come: With the support of smart EMOTION, 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…

    This thread is dedicated to discussing the article. The complete article can be found here: Tune the smart EQ and Twingo ZE to 95 PS and > 140 km/h or simply make it regenerate more

  • It does a bit, yes. :)

    Correct, the actual power from 0-50 km/h is about the same. But the smart responses way more direct / harder to your input, so it's still harder from 0 km/h on.

    According to the German Accumotive, the battery is rated for up to 76 kWh, as seen in the link you've mentioned. Why they still limited the motor to 60 kW, I'm not completly sure. Back when I wrote about the motor, I thought it's the battery. But as Brabus themself started offering smart cars with this performance (but for 40.-60.000 €), they proofed that everything is fine. Technically Brabus cars have the same power train as a regular smart. Only difference is, that they got the higher Brabus software.

  • Hi Moritz could you say whether or not the Performance tune would void the main drive battery warranty for the 453 ED in any way? I read that the tune is plug and play and can therefore be removed, what I am lead to believe, without a trace; safe to assume if I need to take it in for a battery replacement the dealer would never know? Danke Schon!

    It would void the warranty, if it's being found.

    and can therefore be removed, what I am lead to believe, without a trace;

    That's correct. There are no errors or anything stored in the car, when the tune was applied at any time. If it can't be found in the car, they can't tell if it was in the car at any time.

  • Okay sweet, thank you for the response. I feel as long as there isn't any security tape or Warranty void stickers than I'm in the clear. I thought of another question: Does the change in regenerative breaking just make the breaking stronger while still enabling a throttling control of it by way of letting off of or putting more pressure on the accelerator. In other words the operation of the regenerative braking I'm used to now doesn't change just the intensity of the resistance, I imagine, especially when I let off the accelerator entirely? and then another change is that it will actually come to a complete stop without a need for the brake pedal? That's siiick, I despise using the mechanical brakes.

    yes. :)

    No, it won't.

    Ah, I was giving myself the impression it does with this description:

    "In connection with the tuning kit, however, the regen is significantly increased and the smart in OnePedal-Drive mode. It regenerates with up to 40 kW, which comes close to Tesla. In conjunction with the tuning kit, you'll get true one pedal driving and the mechanical brakes are only rarely used anymore." in this article: Tune the smart EQ and Twingo ZE to 95 PS and > 140 km/h or simply make it regenerate more below the "Motor power of the Smart EQ" chart.

  • The only damage concerns I can perceive is from chronic hard acceleration, especially from a standstill, by way of stressing the gearbox and drive axles, is that pretty much it?

    I'd say so, yes.

    Moritz, could you say why the tune is chosen to cap at 70kw and not go closer to the max power potential of the motor? Would it be possible to modify the tune to a higher power? Say up to 80kw?

    Because the software of the car starts outputting errors if you ask it for more than the kit does. The kit does as much as possible, without modifying the car's software at all.

  • The shop is updating you as there are any updates. Usually it takes 2-3 weeks until it's at your doorstep. Right now it's being produced, so that's why you haven't got a tracking number yet.
