AUBURN HILLS, MI - Chrysler Group LLC is revamping its powertrain lineup with technology that will contribute to an overall fuel-efficiency improvement of more than 25 percent during the 2010-2014 period, according to the automaker.
By 2014, more than 80 percent of Chrysler Group's current powertrain lineup will undergo a complete makeover, said Paolo Ferrero, senior vice president, Chrysler Powertrain. Fiat Powertrain technologies, such as Multiair, direct injection, turbocharging and transmission systems will be added to the powertrain portfolio.
FIRE. Fiat Powertrain's 1.4L, in-line four-cylinder Fully Integrated Robotized Engine (FIRE) featuring Multiair. Two variations of the engine will be available, naturally aspirated and turbo.
WGE. The new 2.4L, in-line four-cylinder World Gas Engine (WGE) with Multiair features Fiat's Multiair technology to improve fuel economy and specific-power output.
Pentastar. Chrysler Powertrain will streamline its V-6 gas engine offerings from six options to the new fuel-efficient, 3.6L V-6 Pentastar engine, launching on the all-new 2011 Jeep Grand Cherokee, due out in the second quarter this year. The all-new Pentastar V-6 delivers a fuel efficiency improvement of up to 8 percent on average when compared with previous Chrysler Group V-6 engines and delivers 90 percent of its available torque from 1,800-6,400 rpm. In the all-new 2011 Jeep Grand Cherokee, the 3.6L Pentastar V-6 engine offers an increase of 33 percent in horsepower and an 11 percent improvement in torque over its predecessor. The Pentastar V-6 is designed to use technologies such as Multiair, direct-injection, and turbocharging for future applications.
DDCT. Beginning with mid-size D-segment cars in 2010, Chrysler Powertrain will migrate Fiat's six-speed Dual Dry Clutch Transmission (DDCT) to Chrysler Group vehicles. The DDCT delivers a 10 percent improvement in fuel efficiency while enhancing performance. It transitions seamlessly from economy to sport mode when desired and can handle up to 260 ft.-lb. of torque. The DDCT combines characteristics from both a manual transmission and an automatic transmission, delivering the efficient performance of a locked gear mechanical path, while maintaining the drivability and comfort of an automatic transmission, according to the automaker.
