This Mercedes W123 wagon came from the factory with a OM617 turbodiesel inline-five. However eCap Mobility in Winsen, Germany converted the car to electric. It now has two 53 kW electric motors and 63.3 kWh worth of lithium-ion batteries. The motors give the wagon a maximum speed of 170 km/h (105 mph) while the batteries give it a range of 200 km (124 miles).

Kudos on a job well done. How did you find a Mercedes with such a persistent interior? Guessing you completely redid the interior as well as turning this into an EV. Again, great job!
Kindest Regards,

Waste of a great car. This was the best engine ever made in the best car ever made.
Oh come on… there were 2.7 million W123 produced…
Pretty nice car. But 53 kW? That´s 72 hp. The car is not THAT light and with the added batteries it most likely got heavier. I seriously doubt the better torque curve that comes with an EV-conversion will save it.
Even if they are clearly not going for an performance build, they put so much love and effort into it, why not go for a stronger engine.
The car has two 53 kW motors or about 140 horsepower. Unfortunately they did not list the torque output.
Ohh, sorry, missed that there were two. Thanks for replying to those who cannot read (e.g. Me).
That power should make it perfectly driveable and explains how the car can reach 105 mph.
What is the cost of this conversion?
Hi Christopher. We recommend contacting eCap Mobility in Winsen, Germany or EV West in California, USA to find out the cost of a similar EV conversion.
This is what i’ve been waiting for…… the beginnings of a conversion kit for my beloved w123. Range is still pathetic but a few more years with battery developments and i won’t have to say goodbye to my trusty heap of Benz.
I am working on the conversion of a S123 as well. The technical setup of the W123 and S123 is nearly identical. The main differences are the W123 has the fuel tank behind the back seats, where the S123 has it under it’s floor. And the S123 has the self leveling system (SLS) as standard.
For my car I am aiming to fit a Tesla 3 motor between the rear wheels. and the VW ID-series 82Kw battery pack in the front. This way the weight balances out nicely and the 400v system makes fast charging possible.
It’s a costly conversion, but we are aiming to use our car as a daily driver, doing about 30.000km’s per year.
