Which is bigger, Ford Transit or Ram ProMaster?

The Ford Transit is generally bigger than the Ram ProMaster in most common cargo-van configurations, offering more interior cargo space and a longer overall footprint in its long-wheelbase/high-roof setup. The Ram ProMaster can approach Transit in certain builds, but Transit typically remains larger overall.

Both vans are sold in a range of wheelbases and roof heights, so "bigness" depends on the exact configuration. This article compares maximum practical cargo space, external length, and payload considerations to help buyers decide which van better fits their needs.

How 'bigness' is measured

Size can be defined in several ways: interior cargo volume, exterior length and height, and how much weight the van can carry (payload) or legally tow (GVWR). Ford and Ram offer multiple body configurations in North America, so the largest value depends on which trim and roof-height you choose.

Cargo space by configuration

To illustrate which van yields more usable space in its biggest setup, we compare the top configurations for each model.

Ford Transit configurations

• Ford Transit cargo van: up to about 487 cubic feet of cargo space in the long-wheelbase, high-roof configuration.

Across the Transit lineup, maximum cargo space occurs with the longest wheelbase and highest roof, delivering substantial room for tall items and bulk goods.

Ram ProMaster configurations

• Ram ProMaster cargo van: up to about 463 cubic feet of cargo space in the 159" wheelbase, high-roof configuration.

In practice, the ProMaster's largest-volume setup is slightly smaller than Transit’s top configuration, though it remains very capable for most van-based operations.

Exterior length and footprint

Exterior length and overall footprint influence how the van fits in urban spaces, loading bays, and garage environments. The Transit generally offers the longest options, while the ProMaster covers a broad range with some shorter-length variants.

Length in the longest configurations

• Ford Transit: longest configurations tend to reach the upper end of its segment, providing more overall length than the ProMaster’s longest options.


• Ram ProMaster: aims to balance length with maneuverability, offering several length choices but typically not as long as Transit’s max in the same market.

For operators who need to maximize payload and space while still navigating tight streets, the Transit’s extended-length variants are a key advantage; for some deliveries, a shorter ProMaster may be easier to park and maneuver while still offering ample cargo space.

Payload and GVWR considerations

Payload capacity and GVWR are critical for determining how much weight a van can carry in addition to its own weight. Both vans provide multiple GVWR options and strong payload figures, with the Transit often offering higher max payload in its high-GVWR configurations while the ProMaster can approach similar figures in its heavy-duty trims.

Summary

In most common North American configurations, the Ford Transit is the bigger option in terms of interior cargo space and exterior length. The Ram ProMaster is still a capable choice, particularly in shorter configurations where its footprint is more compact. Always verify the exact wheelbase, roof height, and GVWR for your specific configuration to determine which van truly meets your space and weight needs.

Why did Ford discontinue the Transit?

Ford is not discontinuing the large Transit van, but it is ending sales of the smaller Transit Connect in North America after the 2023 model year due to decreased demand and a strategic focus on reducing costs and complexity. The Transit Connect will continue to be sold in Europe. Additionally, the specialized Transit Trail package was recently discontinued because of supply chain issues and a lack of demand, though this is separate from the discontinuation of the base Transit Connect in North America. 
North America discontinuation (Transit Connect)

• Declining demand: Sales for the compact van segment, including the Transit Connect, have fallen significantly, making it unprofitable for Ford to continue. 
• Strategic shift: Ford is prioritizing cost-saving, efficiency, and its electric vehicle (EV) offerings as part of its global restructuring plan. 
• Other manufacturers followed suit: Other companies, like Ram with the ProMaster City, have also discontinued their small vans in the U.S. 
• Larger Transit remains: The larger Ford Transit van, which is built in the U.S., will continue to be sold. 

Transit Trail package discontinuation

• Supply chain issues: Ongoing supply chain challenges and part availability constraints made it difficult to produce the Transit Trail package.
• Prioritizing parts: Ford decided to remove the package for the 2025 model year to prioritize delivering parts and service for vehicles that already have it.

Which is better ProMaster or Transit?

The main differences are that the Ford Transit offers more engine and drivetrain options (including all-wheel drive) and is more fuel-efficient, while the Ram ProMaster is a front-wheel-drive-only vehicle with a simpler powertrain, a wider interior, and potentially a tighter turning radius for urban maneuverability. The choice depends on your priorities: the Transit is better for performance and varied terrain, while the ProMaster is often favored for its spacious and boxy build, making it a popular choice for DIY conversions, and its urban-friendly handling.

Ford Transit

• Performance: Offers multiple engine options, including a more powerful turbocharged V6, and has the availability of all-wheel drive (AWD), making it more capable on varied terrain. 
• Fuel Efficiency: Generally has slightly better fuel economy. 
• Technology: Features a more advanced infotainment system with larger screen options and more comprehensive driver-assistance technologies.

Ram ProMaster

• Drivetrain: Exclusively front-wheel drive (FWD), which simplifies the powertrain but is less ideal for off-road or low-traction situations. 
• Interior Space: Has a wider and boxier interior with more buildable floor space, making it a favorite for camper van conversions because it is easier to frame out. 
• Maneuverability: The FWD setup gives it a tighter turning radius, making it easier to handle in urban environments.

Which one should you choose?

• **Choose the ** Ford Transit** if:**
  • You need all-wheel drive for driving in adverse weather or on rougher roads. 
  • Maximum cargo volume or a wider buildable area is not your primary concern. 
  • You want more engine choices or a more powerful option. 
• **Choose the ** Ram ProMaster** if:**
  • You prioritize a boxy, wide, and flat interior for a DIY build. 
  • You primarily drive in urban areas and value easy maneuverability. 
  • All-wheel drive is not a priority for your needs. 

How big is the Ford Transit compared to the Ram ProMaster?

The Ram ProMaster offers up to 524 cubic feet of cargo capacity on its largest model, while the Transit offers up to 536.4 cubic feet. However, the slightly larger load space in the Ford model comes at the cost of agility and towing.
