MY $3000 ELECTRIC MERCEDES B-CLASS IS NOW FIXED WITH UPGRADES TO TESLA POWERTRAIN!

EV Channels Review

This video details the extensive repair and upgrade process for a 2014 Mercedes B-Class Electric Drive, purchased for $3,000 in non-functioning condition. The core issue addressed was a common and fatal coolant leak in the Tesla-sourced drive unit, a problem shared with early Model S and second-gen RAV4 EVs. The repair involved a 'coolant delete' procedure, a new 12V battery, and a DC/DC converter, performed by Conduit EV. The reviewer highlights the car's surprisingly robust Mercedes interior quality, ample cargo space, and the Tesla powertrain's strong acceleration, which can easily roast the tires. Despite a minor damper issue and a non-functional heater, the reviewer is highly satisfied with the car's revived performance and daily usability, considering it the nicest among their collection of 'cheap EVs'. The estimated real-world range is around 80 miles, with a usable battery capacity of approximately 28 kWh.
