Mark Wahlberg dropped a fat stack on a new set of quarantine wheels, a custom 3-wheeler that's eco-friendly and street legal!!!

 Mark's newest ride is an Arcimoto FUV -- Fun Utility Vehicle -- which retails for just under $20,000 and it's super cool.

 Mark was one of the first people to test drive the FUV last year, when Arcimoto had a small junket in Los Angeles showing off the new electric whip. We're told Mark liked it from the jump and he finally pulled the trigger while in quarantine.

 sources says Mark's environmentally sustainable ride comes with a custom paint job promoting his health company, F45, and MW feels the FUV is perfect for zipping through his compound and getting around on set.

The FUV sounds pretty fun to whip around ... it tops out at 75 MPH and comes with heated seats and steering grips, Bluetooth speakers, removable doors and a panoramic roof.
