Chrysler's New Four- and Six-Cylinder Engines - Click above for high-res image gallery

If Chrysler is looking to gain any one thing from its new parents at Fiat, it's engine technology. Specifically, the Pentastar will be enlisting its Italian overlords to supply direct injection systems, turbocharging, and Fiat's Multiair variable valve technology, along with new dual-clutch transmissions. Chrysler claims all of this technology is going to boost the overall fuel-efficiency of its vehicles by 25 percent between now and 2014, with over 80 percent of Chrysler, Dodge and Jeep vehicles getting new mills in the process.

To that end, Chrysler has finally announced the details of its new powertrain lineup, including two small-displacement four-cylinders and a new V6.

On the four-pot front, Chrysler will begin fitting one of two new 1.4-liter four-cylinder engines on future models: a naturally aspirated version kicking out 100 horsepower (at 6,750 rpm) and 95 pound-feet of torque (at 4,250 rpm), as well as a turbocharged variant that churns out 170 hp (at 6,750 rpm) and 170 lb-ft of twist (at 3,000 rpm). Chrysler has dubbed these new mills "Fully Integrated Robotized Engines" (FIRE - seriously), and each features Fully Variable-valve Actuation (FVVA) - what we've come to know as Multiair across the Atlantic. Chrysler maintains that both engines offer a 10 percent reduction in emissions and fuel consumption while putting out between 10- to 15-percent more power than its outgoing mills.

A larger displacement, 2.4-liter inline four with Multiair will also come to market, putting out 190 hp (at 6,000 rpm) and 175 lb.-ft of torque (at 4,200 rpm), and along with the new trio of four-cylinders, Chrysler announced specs on the new Pentastar V6. Displacing 3.6 liters and putting out 280 hp (at 6,400 rpm) and 260 lb-ft of torque (at 4,400 rpm), the new six will see similar fuel consumption and emissions reductions and will be fitted to the all-new 2011 Jeep Grand Cherokee later this year.

In 2010, Chrysler says that it will begin to equip its mid-size vehicles (D-segment) with a new six-speed Dual Dry Clutch Transmission (DDCT), that improves fuel economy and can handle up to 260 lb-ft of torque. Expect to see the new tranny making its way into the next-generation Sebring and Chrysler's new crossovers.

And if all that wasn't enough, Chrysler announced its intentions to bring a hybrid Ram 1500 market this year, along with working with the Department of Energy to build a small test fleet of plug-in Rams and minivans, including an electric delivery van for fleet use in 2011 or 2012. All the details are available in the press release after the jump.

so why is the cruze's 1.4 seemingly so underpowered compared to this one?

I'd have to guess that the Cruze's is set up to maximize fuel economy where-as this one is set up for hp. If the internals and fuel system can support it (along with the turbo), more HP is just a bump in boost away!
