Another innovative solution that improves fuel economy is Chrysler Group’s Fuel Saver Technology found in all of the light duty V-8 5.7L and 6.4L HEMI eight-cylinder engines.
By means of cylinder deactivation, it seamlessly alternates between high-fuel-economy four-cylinder mode when less power is needed and V-8 mode when more power is required. Vehicles with multiple displacement systems automatically shift to accommodate different driving conditions and needs. Chrysler Group vehicles with this technology include the automatic transmission versions of the Jeep Grand Cherokee, Chrysler 300/300C, Dodge Durango, Charger, Challenger, and Ram 1500. Fuel Saver Technology is capable of delivering fuel economy savings of approximately 9%. In 2013, 88% of V-8 engines sold by Chrysler Group worldwide incorporated this technology.
Chrysler Group is investigating Powertrain Thermal Management to effectively distribute waste engine heat to reduce oil viscosity, thus improving driveline efficiencies. Future technical strategies to manage and distribute exhaust heat include exhaust / coolant heat exchangers.
Moreover, Magneti Marelli, with its eco-sustainable products(1) contributed €1.41 billion in revenues for 2013, representing an increase of 9.3% over the prior year (€1.29 billion).
