A hybrid driveline assembly for a vehicle includes an engine, an electric motor, and a transmission having an input and an output. The transmission input is selectively coupled to the engine and electric motor. The transmission is shiftable between a plurality of drive modes. The driveline assembly further includes a final drive assembly operably coupled to the transmission output. The final drive assembly has a front final drive operably coupled to a rear final drive.

A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a truck, a tractor unit, a trailer, a tractor-trailer configuration, at a tandem, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.
