When it comes to rugged vocational trucks, Terra EV is as ‘green’ as it gets. These 100% battery-electric off-road trucks are ultra-fast-charge capable, which means they won’t slow down operations. With up to 2x the horsepower and 2x the torque, Terra EV trucks can get the job done faster.
Zero emissions. All the power. Ready to work.
The Boss and Master are top-of-the line vocational trucks built on Western Star 4900XD and 6900XD chassis. Depending on configuration and trailer selection, Terra EV trucks can move up to 180-ton loads.
Both the Boss and the Master are powered by MEDATech's ALTDRIVE, a battery-electric drivetrain system engineered for industrial, off-road use. ALTDRIVE is well known in the mining industry. It’s a drivetrain that’s rugged, proven, and with far fewer moving parts requires far less maintenance than a diesel. It’s also built to last twice as long
