Auburn Hills, Michigan – Chrysler Group LLC is revamping its powertrain lineup as a result of its new alliance with Fiat, using technology that will contribute to an overall fuel consumption improvement of more than 25 per cent over the next five years.
“Chrysler Group will attain leadership by rapidly applying Fiat Powertrain technologies, such as Multiair, direct injection, turbocharging and transmission systems to its powertrain portfolio,” said Paolo Ferraro, senior vice-president of Chrysler Powertrain. “By 2014 calendar year, more than 80 per cent of Chrysler Group’s current powertrain lineup will undergo a complete makeover.”
The companies plan to leverage combined powertrain and vehicle knowledge, using Fiat Powertrain’s expertise in diesel technology and small-displacement gasoline engines of 1.8 litres or less, and Chrysler Powertrain’s knowledge of large-displacement gasoline engines and vehicle electrification technology.
Chrysler Group will introduce Fiat Powertrain’s 1.4-litre inline four-cylinder engine in naturally-aspirated or turbocharged versions, featuring Multiair technology that uses electro-hydraulic variable valve actuation technology for an increase of up to 10 per cent power, an improvement in low-end torque up to 15 per cent, and a reduction in fuel consumption and emissions of up to 10 per cent when compared with similar engines without the technology. The Fiat 500 will be the first North American vehicle to feature the engine.
The company will also introduce a new 2.4-litre inline four-cylinder World Gas Engine with Multiair, and an all-new 3.6-litre V6 Pentastar engine that will first appear in the all-new 2011 Jeep Grand Cherokee.
Beginning with midsize cars in 2010, Chrysler Powertrain will also use Fiat’s six-speed dual dry clutch transmission in its vehicles. The company is also currently developing a Ram 1500 with traditional hybrid capability for 2010, and is considering a small electric delivery van application for 2011 or 2012.
