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.

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.
