The GMC Savana 2500 lineup splits into cargo, passenger, and diesel work-van branches. Regular and base are the shorter cargo vans, while Extended and Extended Extended use the longer body for more load space. Diesel, Diesel Extended, Turbo Diesel, and Turbo Diesel Extended pair the cargo layout with stronger low-speed pulling power. For carrying people, LS is the straightforward 12-passenger model with rear climate control. LT is the more feature-focused passenger trim, keeping the same large-group mission in an upper-level package.
The Work Van trim level, sold as Regular or base, is the shorter and simpler cargo Savana built around maneuverability and durable work-ready space.
Best for: Contractors, delivery operators, and service fleets that value a shorter footprint over maximum cargo length.
Highlights
The Extended Cargo trim level, found as Extended or Extended Extended, stretches the basic work-van formula to carry longer or bulkier loads.
Best for: Trades, delivery fleets, and van upfitters that need more cargo length than the regular-body van provides.
Highlights
Compared with Work Van, it adds the longer body and a larger cargo area.

The Base Passenger trim level, known as LS, is the no-nonsense people mover with simple controls and the basics needed for large-group travel.
Best for: Shuttle operators, churches, hotels, fleets, and large families that need straightforward group transportation.
Highlights
Compared with Extended Cargo, it changes the mission from freight to people by adding 12-passenger seating, rear climate control, and opening side and rear windows.
0 in stockThe Diesel trim level—Diesel, Diesel Extended, Turbo Diesel, and Turbo Diesel Extended—is the cargo branch known for strong low-speed pulling power and commercial-duty durability.
Best for: Businesses that tow, haul heavy loads, or want diesel pulling power in a regular- or extended-body cargo van.
Highlights
This is a separate cargo branch rather than a passenger upgrade; it adds turbo-diesel pulling power and includes both regular- and extended-body versions.
0 in stockThe Premium Features trim level, known as LT, is the upper passenger trim for buyers who want the Savana’s group-carrying layout in a more feature-focused package.
Best for: Shuttle and fleet operators that want the passenger-van mission with the lineup’s higher trim level.
Highlights
This is not a direct step above Diesel; LT is the higher passenger trim above LS, keeping 12-passenger seating and rear climate control in a more feature-focused package.

Regular and Extended identify the two cargo-van lengths in recent years. LS and LT identify passenger vans. Older listings may also use Work Van, Diesel, or Turbo Diesel to describe the body and engine rather than a comfort level.
The Regular Work Van is the shorter cargo model. In recent years it has a standard 4.3-liter V6, roughly 239 cubic feet of cargo room, durable flooring, six tie-down rings, a rear camera, and Tow/Haul mode.
The Extended is the long-body cargo model. On newer vans it uses a 155-inch wheelbase and provides up to 283.6 cubic feet of cargo space while keeping the Regular model’s basic work-focused cabin and standard V6.
LS is the simpler passenger trim. In recent years it has 12-passenger seating, rear climate control, a rear camera, swing-out rear and side-door windows, and a standard 4.3-liter V6.
LT is the upper passenger trim rather than a cargo model. In recent years it keeps the same basic 12-seat layout, rear climate control, rear camera, and standard V6 as LS, but occupies the more feature-focused place in the lineup.
The main difference is length and cargo room. Newer Regular vans hold roughly 239 cubic feet, while Extended vans use a 155-inch wheelbase and hold up to 283.6 cubic feet. The longer van trades easier maneuvering for more load space.
LS is the straightforward passenger trim, while LT is the upper, more feature-focused trim. In recent years both have 12 seats, rear climate control, a rear camera, and the same standard V6, so equipment details on a specific used van matter.
No. In recent years both LS and LT use a standard 12-passenger layout. Moving to LT changes the trim level, not the basic seating capacity or passenger-van body.
Not as a standard difference. In recent years both Regular and Extended cargo vans use a standard 4.3-liter V6. Extended mainly adds body length and cargo room; engine equipment can still differ among used examples.
The Regular Work Van is the better fit for tighter job sites and crowded streets. It has the shorter body while retaining a full-size cargo area, durable flooring, tie-down points, and towing-friendly hardware.
The Extended Cargo van is the better fit. Its 155-inch wheelbase and cargo area of up to 283.6 cubic feet provide more interior length and room than the Regular Work Van.
Look at LS or LT because both are passenger vans with 12 seats and rear climate control in recent years. LS is the simpler choice; LT is the upper trim for shoppers who want the more feature-focused passenger version.
They identify older diesel-powered cargo vans, not luxury trims. The names generally point to the engine and work-van body, while Extended indicates the longer cargo version. Check the engine and body length on the individual van.
Body length is the key difference. The regular Diesel keeps the shorter, easier-to-maneuver cargo body, while Diesel Extended adds the 155-inch wheelbase and roughly 284 cubic feet of room for longer or bulkier loads.
