2009 Dodge Ram powertrain lineup revealed, none gets 23mpg

It was reported last month that Dodge increased the fuel-economy of the 2009 Dodge Ram to 23mpg from 19mpg. Well Chrysler today released a press release giving the details on the powertrain lineup for the 2009 Dodge Ram and nothing gets 23mpg. Instead they announced a new HEMI that gets 13 percent more horsepower and 4 percent better fuel-economy.

Kicking off the lineup is a 3.7L V6 engine that produces 215-hp and 235 lb-ft of torque. Next is a 4.7L V8 that is compatible with E85 fuel and produces 310-hp with 330 lb-ft of torque. A new 5.7L HEMI enters the Ram lineup producing 390-hp and 407 lb-ft of torque with the ability to go from 0-60 in less than 6 seconds (because you’ll definitely be worried about 0-60 when hauling all that equipment in your Ram).

Dodge also announced a 6.7L turbodiesel engine that will be followed by an all-new light-duty diesel 2009.

Chelsea, Mich., Jun 26, 2008  –  This morning, Dodge will showcase its new 2009 Dodge Ram powertrain lineup at the company”s proving grounds. Powertrain choices in all-new 2009 Dodge Ram models will offer improved fuel economy plus more power, torque and refinement than ever before.

Engines available in all-new 2009 Dodge Ram 1500 models include the all-new, best-in-class, 390-horsepower 5.7-liter HEMI®, flex-fuel 4.7-liter and 3.7-liter gasoline engines. The 2009 Dodge Ram Heavy Duty models (with current 2008 design) are available with either the 5.7-liter HEMI or the 6.7-liter Cummins turbodiesel engine, which already achieves 2010 NOx emission standards, making it the cleanest and best-performing heavy-duty pickup truck in the market.

“While the all-new HEMI engine maintains the key characteristics that makes HEMI a household name in powertrains, we added new technologies, including Variable Valve Timing, that substantially improve fuel economy and refinement and maximize performance,” said Bob Lee, Vice President ““ Powertrain Product Engineering Team, Chrysler LLC.

“Our all-new Dodge Ram also offers best-in-class aerodynamics to go hand-in-hand with Chrysler”s fuel-saving technologies,” said Mike Accavitti, Director ““ Dodge Brand and SRT Global Marketing and Communications, Chrysler LLC. “And, with Dodge Ram”s first-ever crew cab, first-in-segment coil-spring rear suspension, industry-first RamBox cargo management system and more than 35 new or improved features, we”re changing the game in the truck market.”

All-new 5.7-liter HEMI to Offer Best-in-class Horsepower and Torque
For 2009, Dodge offers a new generation of the famous 5.7-liter HEMI V-8 in its Ram trucks, with best-in-class horsepower and torque. The new HEMI powers the all-new 2009 Dodge Ram to best-in-class performance: the R/T regular-cab 4×2 model equipped with a short bed and 4:10 gears can accelerate from 0-60 mph in less than 6 seconds.

While the all-new engine maintains many of the basic features that make “HEMI” synonymous with “power,” several technologies were added or improved:

    * Variable Valve Timing (VVT)
    * Expanded operating range of the fuel-saving Multiple Displacement System (MDS)
    * Increased compression ratio
    * Active intake manifold with long runners for low-end torque and short runners for high-rpm power
    * Improved cylinder head port flow efficiency
    * Reduced-restriction exhaust and induction systems

The result is improved idle quality and overall refinement, more horsepower (13 percent), more torque (8 percent) and better fuel economy (4 percent).

“The all-new 5.7-liter HEMI V-8 engine will offer our customers better fuel economy, improved idle quality and overall refinement, along with more horsepower and torque,” said Lee. “HEMI has always been synonymous with power, and now ““ thanks to VVT, expanded four-cylinder mode in our MDS system, and a host of other technologies ““ Chrysler”s new HEMI delivers more fuel efficiency and refinement, along with even more power.”

The new 5.7-liter HEMI V-8 delivers best-in-class 390 hp (291 kW), a 13-percent improvement, and 407 lb.-ft. (552 NӢm) of torque, an 8-percent improvement, while providing an estimated improvement of 4 percent in fuel economy.

The HEMI”s new VVT improves fuel economy under some conditions in two ways. First, it reduces the engine”s pumping work by closing the intake valve later. Second, it increases the expansion process of the combustion event. This allows more work to be transferred to the crankshaft instead of being rejected out of the exhaust port as heat. Essentially, VVT optimizes engine breathing, which improves engine efficiency and power.

Dodge”s fuel-saving MDS system seamlessly alternates between smooth, high-fuel-economy four-cylinder mode when less power is needed, and V-8 mode when more power from the new 5.7-liter HEMI engine is in demand. An expanded MDS operating range in the new-for-2009 HEMI “” aided in part by the Ram”s best-in-class aerodynamics “” will allow customers to realize an even-greater fuel economy benefit. When MDS is operating, it is indicated by the fuel-economy-mode readout in the 2009 Dodge Ram”s Electronic Vehicle Information Center.

Chrysler estimates that since its inception of MDS in 2005, nearly 100 million gallons of gasoline have been saved, along with reduced carbon dioxide (CO2) emissions of close to a million metric tons.

4.7-liter V-8
An available 4.7-liter V-8 delivers 310 horsepower (231 kW) and 330 lb.-ft. (447 NӢm) of torque.

The 4.7-liter V-8 shares some of the HEMI engine”s combustion technology with its twin spark plugs per cylinder. It also makes use of increased compression ratio, improved cylinder head port flow and a new slant/squish combustion system designed to optimize fuel economy, power and torque.

This engine is also compatible with E85 fuel, earning the Flexible Fuel Vehicle (FFV) designation that provides customers the option of operating their vehicle on mixtures of gasoline and ethanol.

3.7-liter V-6
Unlike some others in the marketplace, Dodge will continue to offer customers a V-6 engine.

Standard on all-new 2009 Dodge Ram two-wheel-drive regular cab and Quad Cab® models is a 3.7-liter Magnum V-6 engine, generating 215 horsepower (160 kW) and 235 lb.-ft. (319 N”¢m) of torque.

Similar to the 4.7-liter and 5.7-liter V-8 engines, the 3.7-liter V-6 is equipped with Electronic Throttle Control, which provides engine torque control while compensating for changes in engine load caused by the air conditioning compressor, alternator and power steering pump.

The 3.7-liter V-6 also offers fuel economy and performance benefits from technologies including exhaust gas recirculation, compacted graphite-iron bedplate and internal balance shaft.

6.7-liter Cummins Turbodiesel: Cleanest on the Market
The Dodge Ram Heavy Duty”s 6.7-liter Cummins turbodiesel engine already meets 2010 truck emissions standards in all 50 states, making the 2009 Dodge Ram Heavy Duty the cleanest diesel truck available on the market today.

The inline six-cylinder turbodiesel engine uses a diesel particulate filter (DPF) to virtually eliminate particulate matter emissions and an adsorber catalyst to reduce oxides of nitrogen (NOx) by as much as 90 percent.

In addition to the NOx adsorber and the DPF, the 6.7-liter turbodiesel engine includes other technologies to improve fuel efficiency and reduce unburned hydrocarbons:

    * A cooled exhaust gas recirculation (EGR) system combines with a uniquely designed piston combustion bowl and a high-flow, electronically controlled Variable Geometry Turbocharger (VGT™), matching boost pressure with the engine”s performance needs to reduce emissions and improve drivability
    * Within the exhaust system, a self-cleaning DPF and an oxidation catalyst reduces particulate matter by a factor of 10. The emissions system is designed for a government-certified 120,000 miles
    * A closed crankcase ventilation system eliminates crankcase fumes and oil carry-over, a common process with past diesels

As durable as it is powerful, the 6.7-liter Cummins turbodiesel has life-to-major overhaul intervals of 350,000 miles, providing more than a 100,000-mile advantage over the competition.

All-new Light-duty Cummins Turbodiesel
Dodge will introduce an all-new Cummins turbodiesel engine in its light-duty pickup trucks after 2009.

The new engine will provide a dramatic increase in low-end torque, up to a 25-percent improvement in fuel efficiency and a 20-percent reduction in carbon dioxide (C02) emissions when compared to an equivalent gasoline engine.

With new, clean, quiet diesel technology, the new diesel engine will meet 50-state emissions standards for 2010.
