This mechanical configuration lowers the cargo floor, eliminates the traditional driveshaft tunnel, and maximizes interior standing height and floor space.
Understanding this vehicle requires looking closely at how its design choices translate into daily operational utility. Whether you are considering an individual unit for a small business or managing an expanding fleet, analyzing the physical dimensions, mechanical parameters, package options, and overall performance metrics will help determine if the 2020 iteration fits your workflow requirements.
Mechanical Specifications and Powertrain Performance
At the heart of the 2020 Ram ProMaster 1500 is a single, tried-and-true powertrain combination designed to maximize reliability and simplify fleet maintenance.
Engine and Transmission
Every standard 2020 Ram ProMaster 1500 is powered by FCA's widely utilized 3.6-liter Pentastar V6 gasoline engine. This dual-overhead-cam powerplant produces 280 horsepower at 6,400 RPM and 260 lb-ft of torque at 4,100 RPM. It features aluminum construction, variable valve timing, and a robust architecture capable of handling heavy commercial duty cycles.
Mated to the engine is a 6-speed automatic transmission (specifically the 62TE unit). While some modern commercial vans have transitioned to 8- or 9-speed gearboxes, this 6-speed setup is praised for its predictable shifting behavior, durability, and ease of serviceability. Power is routed exclusively to the front wheels, a defining characteristic that provides superior traction in adverse weather conditions such as rain or snow compared to traditional rear-drive configurations.
Suspension and Steering
The suspension layout consists of a MacPherson strut front suspension with a stabilizer bar, paired with a rear rigid axle utilizing semi-elliptic multi-leaf springs and gas-charged shock absorbers. This setup is tuned to handle payload weight while maintaining relative composure over rough urban asphalt. Rack-and-pinion hydraulic power steering delivers a surprisingly tight turning diameter—ranging from roughly 36 to 40 feet depending on the wheelbase—making urban navigation, parallel parking, and tight alleyway deliveries significantly less demanding.
Dimensions, Configurations, and Cargo Capacity
One of the primary selling points of the ProMaster lineup is its cavernous, boxy cargo area designed to maximize storage efficiency for shelving, bins, and large freight.
Wheelbase and Roof Height Combinations
The 2020 Ram ProMaster 1500 is offered in specific body configurations, balancing wheelbase lengths with roof heights. The 1500 series represents the light-duty end of the ProMaster spectrum, typically available in:
- Low Roof with 118-inch Wheelbase
- Low Roof with 136-inch Wheelbase
- High Roof with 136-inch Wheelbase
(Note: While the 2500 and 3500 series extend into longer 159-inch wheelbases and extended body lengths, the 1500 focuses primarily on shorter to medium lengths to optimize payload ratings and maneuverability.)
Interior Cargo Dimensions
The near-vertical interior walls—sitting at nearly 90 degrees relative to the floor—distinguish the ProMaster from competitors with heavily tapered sides. This geometry allows standard 4x8 sheets of building material to lie flat on the floor between the wheel wells.
- Interior Width: Approximately 75.6 inches maximum, with 55.4 inches between the wheel wells.
- Interior Standing Height: Low roof models offer roughly 65 inches, while high roof models provide an impressive 76.5 inches, allowing most adults to stand fully upright.
- Cargo Volume: Ranges from roughly 259 cubic feet in the base low-roof short-wheelbase variant up to over 420 cubic feet in high-roof configurations.

Operating Costs, Fuel Economy, and Practical Suitability
Evaluating a commercial asset requires understanding its total cost of ownership, fuel consumption patterns, and operational limitations.
Fuel Economy Considerations
Because full-size cargo vans are classified as heavy-duty commercial vehicles (Class 2b/3 variants in higher trims, with the 1500 sitting at the lighter end), official EPA fuel economy ratings are not always mandated or published in the same manner as passenger cars. However, real-world fleet tracking typically places the 3.6L Pentastar V6 in the 14 to 17 mpg combined range, heavily dependent on payload weight, city versus highway driving cycles, and aerodynamic drag from roof equipment.
Maintenance and Reliability
The Pentastar V6 engine is ubiquitous across the Stellantis corporate family, ensuring that replacement parts, filters, and routine maintenance items are widely available, affordable, and familiar to most independent mechanics and fleet service centers. The front-wheel-drive layout eliminates the need for differential fluid changes on a rear axle, simplifying long-term drivetrain upkeep.
Operational Limitations
While the front-wheel-drive layout provides excellent low-speed traction in snow, it has limitations when climbing steep, loose-surface inclines under maximum payload. Operators requiring heavy towing capacity exceeding 5,100 pounds or serious off-road capability will need to explore heavier-duty platforms or alternative chassis options.
