Chrysler Adds 6.4L Engine for its 2014-MY Ram Chassis Cabs

June 28, 2013

The 2014 Ram Chassis Cab 3500, 4500 and 5500 come standard with the new 6.4-HEMI V-8 gasoline engine — the first implementation of a gasoline engine for the Ram 4500 and 5500 Chassis Cab models, according to the automaker. The Chassis Cab version of the 6.4 HEMI is similar by design but is engineered for a different duty cycle, when compared to the version offered in the Ram 2500 and 3500.

The 16-valve engine achieves up to an estimated 410 hp  and a peak torque rating of 429 lb.-ft. Ram’s new 6.4-liter V-8 gasoline engine is the first of its kind for Class 4 and 5 Ram 4500 and 5500 Chassis Cab trucks, according to the comaany.

The new gasoline engine offers a number of features, including the dual-alternator option and a programmable idle shut-down timer. Additionally, the engine features Fuel Saver cylinder deactivation operation under normal driving and during PTO mode to improve efficiency.

The new 6.4-liter HEMI is available with the 66RFE six-speed automatic transmission or the AS66RC six-speed automatic transmission with segment exclusive, gasoline engine left- or right-side PTO capability.

The 3500 Chassis Cab also is available with a 5.7L HEMI V-8 gasoline engine. The engine produces 383 hp and generates peak torque of 400 lb.-ft. . Mated to the 66RFE six-speed automatic transmission, the HEMI features enhanced fuel efficiency and power output, thanks to the incorporation of variable-valve timing (VVT) and a compression ratio of 10.5:1, according to the automaker. Refinements and other applied technologies provide the latest-generation HEMI with performance and fuel economy improvements to rival multi-valve V-8 offerings.

Ram also offers two engine variants based on the 6.7L Cummins for diesel supremacy in the segment.

The first version features 320 hp and 650 lb.-ft. of torque. The engine is paired with Ram’s segment-exclusive six-speed manual transmission, which features a wear-compensating clutch for consistent performance and a dual-trunion shift tower to accommodate a compact shift pattern.

The second version delivers 325 hp and generates torque of 750 lb.-ft. The engine is paired with an Aisin six-speed automatic transmission (AS69RC).

The Aisin AS69RC transmission is designed for high engine ratings and enables a left- and right-side PTO option, as well as allowing for a split shaft PTO configuration (diesel). Fire pumpers, dump beds, aerial buckets, cranes, and onboard compressor/generators are typical PTO based upfits, according to the automaker.

New for 2014, Ram 3500 Chassis Cab trucks are equipped with a front-axle disconnect for greater fuel efficiency.

All Ram Chassis Cab diesels benefit from an advanced cooling system. A high-efficiency fan, dual radiators, dual transmission coolers and charge air cooler. Lower operating temperatures deliver better performance, durability, and lower operating costs, according to Ram.

Best-in-class GCWRs also led to the Ram Active Air intake system, activated by monitoring capabilities in the engine controller. When the exclusive intake system senses extreme heat, it draws cooler air from the front of the vehicle – a function that also engages at high altitudes for superior throttle response in low-oxygen environments, according to Ram. When conditions are wet from snow, ice or water fording, the system pulls air from an under- hood inlet, clear from snow packing and water ingestion.

A new, dual fuel tank option combines 52-gallon and 22-gallon tanks for 74 gallons of extended, integrated onboard fuel range for lower operating costs. Additionally, a mid-ship 22-gallon tank is now an option for gasoline- and diesel-powered Chassis Cabs.

Ram Chassis Cab trucks offer more than 45 active and passive safety and security features, including standard front air bags with Enhanced Accident Response System (EARS), knee bolsters, seat-belt pretensioners, BeltAlert and ParkView rear backup camera system, according to Ram.

A selective tire pressure display is standard for both single- and dual-rear-wheel 3500 models.

The 2014 Ram Chassis Cab models include standard electronic stability control (ESC), which hosts a number of technologies including all-speed traction control, trailer-sway control, Hill-start Assist (HAS) and anti-lock brake system (ABS).

The 2014 Ram Chassis Cab also offers Keyless Enter ’n Go technology, which allows the doors to be unlocked and the truck to be started without having to touch the key fob. An available remote start feature allows a driver to start their truck from up to 300 feet away. Door controls, illuminated entry, engine immobilizer and panic alert are standard features with the Keyless Enter ’n Go system. Auto rain-sensing wipers and SmartBeam headlamps also are offered, adding to a long list of content.

Start of production of the 2014 Ram 3500, 4500 and 5500 Chassis Cab is scheduled for the first quarter of 2014 at the Saltillo Truck Assembly Plant in Coahuila, Mexico.
