Hybrid Diesel-Electric System with Export Power

Power. On the move.

Designed for the performance demands of heavy-duty vehicle applications, the Oshkosh® ProPulse® hybrid diesel-electric system dramatically improves fuel economy up to 20 percent and serves as an on-board generator with enough output to power an entire airfield or hospital.

Performance Capabilities

Allows compact, lighter weight vehicle designs

On-board generator delivers up to 120 kW of AC power for external operations

Already proven effective on the Oshkosh® Heavy Expanded Mobility Tactical Truck (HEMTT) A3 and Medium Tactical Vehicle Replacement (MTVR), ProPulse technology uses a modular series-hybrid arrangement to simplify the transmission of power to the wheels. Its diesel engine powers a large electric generator distributing power to each axle module, which is driven independently by a dedicated motor controlled from its own power converter. And life-cycle costs are dramatically reduced because the full electric system lowers torque throughout the drivetrain and regenerative braking increases brake life.

Fuel Economy

% Fuel Economy Improvement Over Conventional Driveline Vehicle*

+35% at 20 mph (32 kph) cruising speed

+20% at 60 mph (96.5 kph) cruising speed

+30% start/stop (0-25 mph; 0-40 kph)

*Preliminary Oshkosh internal test data

ProPulse hybrid diesel-electric system enables significant fuel economy because of a tailored engine control strategy.
