Kiessling Transit orders 32 more Lightning Hybrids hydraulic hybrid buses

Kiessling Transit, a Massachusetts-based transportation company, is ordering 32 more hydraulic hybrid buses equipped with Lighting Hybrids’ Energy Recovery System (ERS) for medium- and heavy-duty trucks and buses.

This order for 32 units follows an order last year from the Boston-area transit company for 35 units that were commissioned in September 2015. (Earlier post.) Those vehicles have recorded close to a total of one million miles. The ERS has demonstrated improvements of 25% in fuel efficiency, and significantly reduced tailpipe emissions. In addition, Lightning Hybrids has identified ways to reduce vehicle idle time by up to 30%.

Kiessling Transit has received a grant from the Commonwealth of Massachusetts that pays for 80% of the cost of the Lightning Hybrids’ systems to be installed on Kiessling Transit’s Ford E-450 passenger buses, making them cleaner, more fuel efficient and improving braking efficiency.

The ERS is a patented, parallel hydraulic hybrid system that has no electric batteries. Instead, it applies a hydraulic system to the driveline of a vehicle to regenerate braking energy. Hydraulic pumps and a lightweight accumulator brake the vehicle, store the energy, and then use that stored energy to provide power to the wheels.


When put in service, the buses will provide an immediate positive impact on the environment due to the reduced emissions of the system. For example, vehicles with Lightning Hybrids’ technology produce half of the NOx emissions and 25% fewer CO2 emissions, compared to vehicles without the company’s system. In addition to these emissions reductions, the Kiessling fleet will see decreased fuel use, longer brake life, better low-end torque, and lower maintenance and operational costs.

The hydraulic hybrid product was installed and is being maintained by Lightning Hybrids’ East Coast distributor, National Fleet Hybrids, located in Attleboro, Mass.

Lightning Hybrids’ proprietary fleet data analytics software, which tracks and evaluates vehicle and system performance was tested and proven on the Kiessling fleet. The results, logged through Lightning Hybrids’ telematics systems and confirmed through Kiessling’s fuel logs, revealed the improvements in fuel economy and reductions in emissions. Driver feedback also confirmed vehicle performance benefits.

Lightning Hybrids’ hydraulic hybrid Energy Recovery System (ERS) is sold through a network of dealers and upfitters.
