Dana offering Spicer PowerBoost hydraulic-hybrid system for off-highway field testing; demonstrated fuel savings of 20-25%
January 25, 2015
Dana engineers have conducted extensive field tests of the Spicer PowerBoost system integrated with a dual-motor hydrostatic transmission in a series configuration. These functional evaluations include more than 1,000 hours on a 16-tonne (17.5-ton) front-end loader and more than 500 hours on a telescopic boom handler powered by an 83 kW (111 hp) engine. These tests of typical duty cycles have verified fuel savings of more than 20% for the front-end loader and more than 25% on the telescopic boom handler, with an expected payback in under 18 months for both applications.
Parker Hannifin gaining traction with RunWise HD hydraulic hybrid; developing CNG-based HD system, next-gen MD system
October 09, 2014
Parker Hannifin is seeing growing acceptance in the market for its RunWise heavy-duty hydraulic series hybrid system (earlier post), currently only applied in Autocar refuse trucks. After the introduction of pilot units in 2010, Parker is now close to the 100-unit mark with the RunWise system, with 84 of those in the North American market, and another 70 being built or on order, said Mark McGrew, RunWise sales manager. “Things are continuing to press forward in a very good way,” he added. “Within the last 6-12 months, we’ve seen tremendous traction.”
In addition to seeking more heavy-duty applications for the RunWise hybrid system—such as transit—McGrew said that the company is working on a new generation of the product that should launch in 2016 for Class 4-6 delivery trucks—e.g., FedEx, UPS, etc. (Earlier post.) Further, Parker Hannifin has paired a RunWise transmission with a CNG engine in the series hybrid powertrain as a one-off to test the waters for such a combination, McGrew said.
Citroën unveiling Cactus AIRFLOW 2L concept at Paris: Hybrid Air powertrain and 2L/100 km
September 18, 2014
Citroën will unveil its new C4 Cactus AIRFLOW 2L concept at the Paris Motor Show. With the C4 Cactus AIRFLOW 2L concept, Citroën is demonstrating fuel consumption of 2l/100 km (118 mpg US) through the use of optimized design with a 20% improvement in aerodynamics; lower rolling resistance (Tall&Narrow) tires; efforts to use lighter parts and thus reduce overall vehicle weight by 100 kg; and the implementation of Hybrid Air technology (earlier post), which cuts fuel consumption by 30%.
The C4 Cactus AIRFLOW 2L project was conducted as part of the “2l/100 km vehicle” program set up by the Plateforme de la Filière Automobile, an industry group. The objective was to deliver practical solutions to reduce the impact of vehicle running costs, on household expenditure and to reduce the eco-footprint of car travel.
Peugeot showcasing 208 Hybrid Air 2L Demonstrator at Paris show
September 12, 2014
PEUGEOT is showcasing its 208 HYbrid Air 2L Demonstrator at next month’s Paris Motor Show. The 2L stands for two liters per 100 km, equivalent to 118 mpg US, and is based on a production version of the Peugeot 208 1.2-liter PureTech 82 hp 5-seater Hatchback.
Peugeot’s Hybrid Air (earlier post) is a full-hybrid solution combining compressed air and hydraulic power, with no battery required for energy storage. Hybrid Air combines the PureTech gasoline engine; a compressed air energy storage unit located beneath the trunk; a hydraulic pump/motor unit in the engine bay; and and an automatic transmission with an epicyclic gear train.

Lightning Hybrids, a maker of hydraulic hybrid systems for medium- and heavy-duty trucks and buses (earlier post), released initial results from emissions testing conducted by an independent testing facility in Colorado of two medium-duty trucks upfitted with the Lighting Hybrids system. The results show decreases in NOx of up to 90% and decreases in CO2 emissions of up to 16% over the same baseline vehicle, depending upon the drive cycle tested.
Lightning Hybrids tested two vehicles: a 2013 Ford E450 6.8-liter V10 and a 2010 GMC 3500 Savana Cutaway 6.0-liter V8. Both vehicles were first tested without Lightning’s hydraulic hybrid system to provide a baseline with which to compare the results with the hybrid system installed.
Peugeot showing new 108, new engines, new HYbrid Air implementation at Geneva Show
February 17, 2014
Peugeot will unveil two all-new models—the 108, successor to the popular 107; and the 308 SW—and two new engine technologies—the 1.2-liter PureTech e-THP three-cylinder turbocharged gasoline engines and new BlueHDi diesel emissions technology, to appear on several versions of PEUGEOT 308, 308 SW and 508—at the forthcoming Geneva Motor Show.
The company will also showcase a 2008 HYbrid Air crossover—an implementation of Peugeot’s HYbrid Air hybrid system (earlier post) in a 2008 Crossover. HYbrid Air is a full-hybrid solution combining compressed air and hydraulic power, with no battery required for energy storage. Hybrid Air combines a PureTech gasoline engine, a compressed air energy storage unit, a hydraulic pump/motor unit and an automatic transmission with an epicyclic gear train.
