Hummer has announced enhancements to their 2010 H3 and H3T. The new enhancements include an E85 Flex Fuel capable 5.3L V8 engine and three new exterior colors (Red Rock Metallic, Silver Stone Metallic, and Canyon Metallic). The new engines will be standard for all 2010 Alpha Series models. These new engines feature 300 HP and an aluminum cylinder block that should help reduce overall mass and maintain a balanced front-to-rear weight balance.

These new models are expected to arrive by December, 2009 in North America. The H3 will be priced starting at $33,390 while the H3T starts at $30,915.

An all-new engine from Chrysler is set to debut once the 2011 Jeep Grand Cherokee hits the market. Chrysler LLC introduced today an all-new line of V-6 engines that will improve fuel efficiency across the Chrysler, Jeep and Dodge lineup by 8 percent on average compared with previous Chrysler V-6 engines. This more refined and fuel-efficient V-6 engine will ultimately replace seven current Chrysler V-6 engines.

The new 3.6-liter V-6 engine, named Pentastar, is part of the company’s overall $3 billion powertrain offensive. It will first be offered in the all-new 2011 Jeep Grand Cherokee, unveiled today at the New York International Auto Show and at the Jeep Safari in Moab, Utah.

The Pentastar is an all-new design, featuring double-overhead camshafts (DOHC) and a high-pressure die-cast aluminum cylinder block in a 60-degree configuration.

In the all-new 2011 Jeep Grand Cherokee, the all-new 3.6-liter Pentastar V-6 engine will deliver 280 horsepower (209 kW) at 6,400 rpm and 260 lb.-ft. (353 N*m) of torque at 4,800 rpm — an increase of 33 percent in horsepower and 11 percent in torque over its predecessor — while providing an 11 percent fuel economy improvement.

Chrysler’s all-new 3.6-liter Pentastar V-6 engine design features a double-overhead cam (DOHC), narrow included valve angle, cylinder head and high-flow intake and exhaust ports. This design, combined with dual independent cam phasing, allows optimum volumetric and combustion efficiency over the full speed and load range, resulting in an exceptional, flat torque curve along with high specific power — the engine’s torque exceeds 90 percent of its peak value from 1,600 to 6,400 rpm — which will provide customers with outstanding drivability and responsiveness, without the need for premium fuel.
