Powertrain & Engine Architecture
The heart of this RAM 2500 is the 6.7-liter Cummins inline-six diesel engine, designated as the ETJ code. This engine represented a significant upgrade over previous Cummins offerings, featuring a common-rail fuel injection system for improved efficiency and reduced emissions. The common-rail system allowed for multiple injection events per combustion cycle, optimizing fuel burn and reducing engine noise. The engine also incorporated a variable geometry turbocharger (VGT) and an intercooler to enhance power and torque across the rev range. The 350 horsepower output was achieved at 3000 rpm, while the impressive 881 Nm (649.79 lb-ft) of torque was readily available at a low 1500 rpm. This made the truck exceptionally capable for towing and hauling. The automatic transmission used was a six-speed unit, designed to handle the substantial torque output of the Cummins engine. It was calibrated for smooth shifts and optimized for both on-road driving and demanding work applications.
Driving Characteristics
The 6.7L Cummins with the automatic transmission delivered a driving experience focused on usability and capability. While not as overtly sporty as some gasoline-powered trucks, the diesel offered a broad, flat torque curve that made hauling heavy loads feel effortless. The automatic transmission, while smooth, wasn’t designed for rapid gear changes. It prioritized durability and consistent performance under load. Compared to the manual transmission versions of the same engine, the automatic offered greater convenience, particularly in stop-and-go traffic. However, the manual transmission generally provided slightly better fuel economy and a more direct connection to the engine. The gear ratios were optimized for towing, with a lower first gear for getting heavy loads moving and a relatively tall overdrive gear for efficient highway cruising.
Equipment & Trim Levels
The 2500/3500 Crew Cab I with the 6.7L Cummins and automatic transmission was typically offered in mid-range trim levels, such as the SLT or Laramie. Standard features included air conditioning, power windows and locks, a basic audio system, and cloth upholstery. The Crew Cab configuration provided ample space for passengers, making it a popular choice for families and work crews. Optional extras included leather upholstery, a premium sound system, navigation, heated seats, and a sunroof. The Laramie trim, being the more premium option, added features like chrome exterior accents, upgraded interior materials, and additional convenience features.
Chassis & Braking
The RAM 2500/3500 featured a robust chassis designed to withstand the stresses of heavy-duty use. The front suspension utilized a double wishbone setup, while the rear suspension employed leaf springs. This combination provided a comfortable ride while maintaining excellent load-carrying capacity. Braking duties were handled by disc brakes on all four wheels, coupled with an Anti-lock Braking System (ABS) for enhanced safety. The braking system was appropriately sized to handle the truck’s weight and towing capacity. The rear axle ratios varied depending on the specific configuration and intended use, with lower ratios (numerically higher) being preferred for heavy towing and higher ratios for improved fuel economy.
Market Reception & Comparison
The 2010-2012 RAM 2500/3500 with the 6.7L Cummins and automatic transmission was generally well-received by critics and consumers alike. It was praised for its powerful engine, comfortable ride, and spacious interior. Compared to its competitors – the Ford Super Duty and Chevrolet/GMC HD trucks – the RAM offered a more refined driving experience and a more modern interior. Fuel economy, while not a primary concern for heavy-duty truck buyers, was competitive with other diesel-powered trucks in its class. Reliability was generally good, although some owners reported issues with the automatic transmission and the diesel particulate filter (DPF) system.
Legacy
The 6.7L Cummins engine has proven to be exceptionally durable and reliable, and examples of this powertrain continue to be highly sought after in the used truck market. The automatic transmission, while occasionally prone to issues, is generally considered robust when properly maintained. These trucks represent a good value for buyers seeking a capable and comfortable heavy-duty pickup. The 2010-2012 generation RAM 2500/3500 established a strong foundation for the continued success of the Ram Heavy Duty line, solidifying its position as a leading contender in the competitive American truck market. Proper maintenance, including regular oil changes and DPF servicing, is crucial for ensuring the long-term reliability of this powertrain.
