Extended field trials with Iveco Daily hybrid diesel/electric-powered vehicles are beginning in Italy, after the company delivered 10 Daily hybrids to express air delivery company FedEx Express. The vehicles will be used on routes between Milan and Turin.
Iveco claims fuel consumption and carbon dioxide emissions reductions of up to 30% in urban driving cycles. Compared with a vehicle equipped with a conventional diesel powertrain, the trial vehicles are expected to use about 6000 L (1585 gal) less diesel fuel each year. Claimed CO2 emissions reductions are approximately 15 t (16.5 ton) per annum per vehicle compared with a conventional powertrain. Contributing to these reductions are the automatic engine stop/start and regenerative braking-energy-recovery systems.
The parallel hybrid powertrain consists of an Iveco diesel engine and a vehicle management unit jointly developed by Fiat Powertrain Technologies and Magneti Marelli. Bosch supplies the starter clutch, motor/alternator, inverter, electronic control unit, and starter motor. ZF provides the gearbox clutch and automated manual transmission, similar to that used in the Daily Agile model. Johnson Controls provides the battery system. After the Italian trials have begun, FedEx Express will expand to other European cities, with trials expected to begin in Paris soon. The company operates around 100 hybrid vehicles around the world.
Iveco has produced hybrid versions of the Daily before, and the latest Daily hybrid models can be seen as a development of the Daily Ecodriver, developed jointly with Bosch and based on the previous-generation Daily.
The Daily Ecodriver was also equipped with a parallel hybrid system using Iveco’s 2.3-L four-cylinder common-rail diesel engine combined with a 45-kW electric motor/generator, 400-V battery pack, and a six-speed automated transmission.
Two passenger-carrying versions of the Daily Ecodriver were supplied to Turin’s public transport operator Gruppo Torinese Trasporti in 2006. The vehicles were used for passenger transport during the 2006 Turin Winter Olympic Games.
Commenting on the trial, Paolo Monferino, Iveco’s Chief Executive Officer, said: “We are committed to the development of this technology, and the next step is to make it affordable for our customers. In order to meet customer demand, Iveco will introduce hybrid powertrain technology in our vehicle production facilities by the end of 2009.”
