M4 Hybrid
Contact us for current availability and factory lead times.
The world's first purpose-built electric hybrid street sweeper. Cummins ISB-200 6.7L diesel paired with electric drive motors and lithium-ion batteries delivers over 50% fuel-economy improvement and reduced emissions and noise, with 60 mph travel speed and 5.6 cubic yard hopper.
Over 50% increase in fuel economy vs. conventional diesel sweepers
Cummins ISB-200 6.7L diesel (200 HP) with electric drive motors and lithium-ion batteries
5.6 cubic yard hopper, 12,000 lb lift capacity, 16,660 lb curb weight
0–14 mph sweeping (low) and 0–60 mph travel (high), electric drive maintains broom speed independent of vehicle speed
Reduced noise levels for early-morning or noise-sensitive sweeping
Available in high or low dump configurations
Available with on-board dust suppression for fine-particulate routes
Same heavy sweep package as the M4 diesel, same 250-gallon water tank
Municipalities with fleet-wide emission-reduction targets that still need full diesel range and payload. The M4 Hybrid delivers a 50%+ fuel savings and lower emissions without committing to the charging infrastructure a full EV requires. Ideal for cities transitioning fleets toward electrification in stages.
Fleet electrification programs with mandated emission reductions
Early-morning and noise-sensitive residential sweeping
Long-route sweeping where EV charging range would be limiting
Budget-conscious green-fleet initiatives unwilling to wait for full EV infrastructure
Operations combining city and highway sweeping with 60 mph transport capability
The world's first purpose-built hybrid street sweeper, not a diesel with stop-start grafted on. Electric drive motors maintain constant broom speed independent of engine RPM, which means the broom keeps sweeping at full power when the operator slows to a crawl for a tight corner. 50%+ fuel savings translate to roughly 650 fewer gallons of diesel per year on a typical municipal route, that's the hybrid's payback math in a single line. No DEF freeze issues because the hybrid runs the Cummins less overall. For fleets under emission-reduction mandates but not ready for full electrification, this is the transitional platform.
Municipal fleets facing state or city emission-reduction mandates with no budget for full EV infrastructure, or sweepers returning from the dump cycle and idling half the day while fuel costs keep rising.
If your mandate requires zero tailpipe emissions, the M4EV is a 100% plug-in electric version with no diesel. If operating cost is the only concern and emissions aren't regulated, the standard M4 costs less upfront and delivers comparable throughput on diesel alone.

Frequently Asked Questions
Who is the M4 Hybrid best suited for?
Municipalities with fleet-wide emission-reduction targets that still need full diesel range and payload. The M4 Hybrid delivers a 50%+ fuel savings and lower emissions without committing to the charging infrastructure a full EV requires. Ideal for cities transitioning fleets toward electrification in stages.
What are the main applications for the M4 Hybrid?
The M4 Hybrid is ideal for: Fleet electrification programs with mandated emission reductions; Early-morning and noise-sensitive residential sweeping; Long-route sweeping where EV charging range would be limiting; Budget-conscious green-fleet initiatives unwilling to wait for full EV infrastructure; Operations combining city and highway sweeping with 60 mph transport capability.
What sets the M4 Hybrid apart from other mechanical street sweepers?
The world's first purpose-built hybrid street sweeper, not a diesel with stop-start grafted on. Electric drive motors maintain constant broom speed independent of engine RPM, which means the broom keeps sweeping at full power when the operator slows to a crawl for a tight corner. 50%+ fuel savings translate to roughly 650 fewer gallons of diesel per year on a typical municipal route, that's the hybrid's payback math in a single line. No DEF freeze issues because the hybrid runs the Cummins less overall. For fleets under emission-reduction mandates but not ready for full electrification, this is the transitional platform.
When should I consider a different model instead of the M4 Hybrid?
If your mandate requires zero tailpipe emissions, the M4EV is a 100% plug-in electric version with no diesel. If operating cost is the only concern and emissions aren't regulated, the standard M4 costs less upfront and delivers comparable throughput on diesel alone.
What is the typical upgrade path from the M4 Hybrid?
Municipal fleets facing state or city emission-reduction mandates with no budget for full EV infrastructure, or sweepers returning from the dump cycle and idling half the day while fuel costs keep rising.
