Mitsubishi Delica L300 vs L400: A Comprehensive Guide

If you're considering the Mitsubishi Delica for your next adventure vehicle, you're making a smart choice. The Mistubishi Delica is a very capable and compact campervan that punches above it’s weight class.

The next step is determining which model best aligns with your needs. In North America, the two primary Delica variants are the L300 Starwagon and the L400 Spacegear. Both are available with either a gasoline or turbo-diesel engine, and offer automatic or manual transmissions paired with a two-speed transfer case.

Rather than identifying a single “best” Delica, this article is designed to help you evaluate which model and configuration best suits your preferences—based on the unique characteristics and capabilities of each model.

The Quick Answer

If you prefer a rugged look and feel, go with the L300. It has all of the unique JDM quirks and features you could possibly want. It also boasts a great fuel economy of 22 MPG or more with the Nomadic Tune. However, the L300 has a lower cruising speed of 65 mph and will encourage a more active posture in the driver seat compared to newer models. The trade-off being its ability to perform quite well offroad, for a van. The Delica L300 Starwagon is for the JDM car enthusiast that respects the mechanical needs of an older vehicle. It’s a ~30 year old van, so ideally you are checking your fluids before long trips.

For those craving modern comfort with extra muscle, the L400—gas or diesel—is the more effective choice. With more powerful engines and enhanced suspension, it offers a smoother ride, faster cruising speeds approaching ~80 MPH, and a distinctly contemporary feel. You’ll trade a bit of fuel efficiency for the thrill, but the payoff is worth it for drivers who want to chase adventure without compromising a cozy driving experience.

Delica Production Years

The L300 and L400 had a bit of overlap in Japan. The Delica L300 Starwagon was produced from 1986 to 1999 for the Japanese market and continued for foreign markets, like New Zealand and Australia, through 2013. The L400 Spacegear was produced from 1994 to 2007 for the Japanese market with a 5-year overlap with its predecessor. Imagine being at a Mitsubishi sales lot in 1996 and seeing two iterations of the same model, brand new. Ninety percent of the versions you’ll see imported into the US will be right hand drive because the Japanese versions came with more of the cool factory options and are typically in better shape and have less mileage on the odometer. Certain left hand drive versions that were manufactured for Europe were released in unique L300 long wheelbase, dual sliding door editions. However, we have never come across the opportunity to import one.

Interestingly enough CMC, China Motor Corporation, began manufacturing the Starwagon in left hand drive editions in 1991 and began producing the Spacegear in 2001. The company still releases new versions every year for the Taiwanese market. New versions come with upgraded powerplants and transmissions, of course. Sadly, we cannot import anything newer that 25 years old, but rumor has it that certain add-ons like headlights and bumpers fit the old models. Unrealistic logistics including shipping methods and overhead costs, have made importing a LHD van to our dealership difficult. Hopefully this will change in the near future and the occasional LHD Delica will pop up on our site. Keep your eyes peeled!

L300 vs L400 Size Comparison

Hopefully, our rudimentary diagram helps put in perspective the size difference between these vans.

The L300 stands out for its compact build and exceptionally short wheelbase, making it the most maneuverable Delica—especially in tight spaces. Its cab-over design places the front axle beneath the driver, reducing overall length and offering off-road visibility advantages, like easily spotting close obstacles and precisely placing tires. There’s no hood impeding your view, which is a very unique feeling in the driver seat.

By comparison, the L400 SWB is only 7 inches longer in body but stretches 22 inches further in wheelbase. Its more conventional front-engine layout offers a smoother ride for front passengers and greater stability at high speeds, though maneuverability decreases slightly.

The L400 LWB adds another 8 inches to the SWB's wheelbase—30 inches more than the L300—resulting in a wider turn radius and less agility. It should go without saying but it’s a bit easier to high-center the LWB offroad than the L300. However, this extra length provides increased rear storage thanks to an extended overhang behind the rear wheels.

Importantly, all Delica models remain compact by modern standards. For example, the L400 LWB's 9-foot 10-inch wheelbase is still shorter than a 3rd gen Toyota Tacoma’s 11-foot wheelbase, making the Delica lineup impressively nimble in today's overlanding landscape. More information about the multiple trade-offs with wheelbase lengths can be found HERE.

As you can see above, all of the L300 and L400 Delicas are still substantially smaller than an average midsize pickup, with the only exception being height.

L300 vs L400 Interior Space

The L300 stands out again for its compact size while still having plenty of interior space. From the driver’s seat to the rear hatch, the L300 has 8 feet 5 inches of space. The SWB and LWB L400s come in at 7 feet 4 inches and 8 feet 9 inches, respectively. The L300 also offers a little more interior width than either of the L400 options; 60 inches compared to the L400’s 59 inches.

Each van is an expose’ of Japan’s cultural minimalism. Japanese design values simplicity and intentional living. Given the small platform of the Delica, storage space was hard to integrate during the design phase. However, they found space to stash your jacket and shoes inside a sliding cubby bin under the passenger seat of the L400. With the third-row seat of the L300 able to sit in 8 different positions, we’re sure you’ll find space for most of your gear. Rondo says he can fit three medium size mountain bikes upside down and still close the hatch.

Most importantly, each van is able to fit a full-size mattress wall to wall, on top of the folded seats in the rear cabin of the van. This still leaves room for a cooler and a few gear bags behind the third row. Underneath the bed, there’s plenty of room for extra stuff, like snowboards, skis, camp chairs, and skewers for smores. So, the real question is, ‘do you really need to take the time to build-out the van’s interior?’ There’s people who like to keep all of the seats inside for shuttling friends to the top of the mountain bike trail. Others prefer to try and create a “cabin in the woods” feeling by removing the seats and adding some wood paneling. Is that a necessary effort? You can be the judge of that.

Lastly, the Starwagon never was released in the Japanese Domestic Market with many safety features. Apart from hydraulic disc brakes, 3-point harness seatbelts, and an emergency brake, the L300 wasn’t released with anything too fancy to defend your bodily health. However, the L400 was released with a driver side airbag in late 1996 and soon after was offered with dual front airbags. The next addition to the van was ABS or anti-lock brakes in late 1997. Given these features, your opinion may be swayed toward the L400 for this reason alone.

L300 vs L400 Fuel Economy and Engine Performance

Is the Delica fuel efficient?

It depends on who you ask. By most standards, the Diesel L300 is considered fuel efficient in the U.S. Here, it’s more about the ratio of versatility and cargo capacity to fuel economy. With our Nomadic Tune, we are able to get 22 MPG or more out of the 4D56. Without the tune, it is fairly typical to average 18 MPG. You’d be hard pressed to find another “overlanding” vehicle that is more fuel efficient than the L300 with the 4D56 engine.

The L400’s engines, the 4M40 turbo diesel and 6G72 Gasoline V6, will fall around 16-19 MPG depending on the model, modifications and driving style.

What is the best Delica engine?

Between the four options, there is no universally “best” Delica engine—it ultimately comes down to which option best aligns with your specific needs and priorities. Generally speaking, the L400 series engines are regarded as more reliable and require less maintenance, which has contributed to their popularity among JDM van enthusiasts. However, the L300 offers distinct advantages of its own.

Both of the gasoline engines released in the Delica were also released in the US domestic market in many cars, vans and SUVs. Between 1987 and the late 2000s, both the inline 4 cylinder and V6, were commonly found on US roads. Because of this, parts can be found at Napa, O’Reilly and Carquest for general maintenance needs. Also, this means that mechanics across the country are familiar with them, which will allow for a larger support system coast to coast than some of the diesel options.

When evaluating gasoline versus diesel options, it’s important to note that the diesel engines—particularly those in the L300 & Series 1 L400—are predominantly mechanical. This simplicity reduces the likelihood of electronic failures and makes diagnostics more straightforward. These diesel engines also feature forged internals in the bottom end, engineered for high compression levels exceeding 400 PSI per cylinder. This robust construction supports effective downhill engine braking, enhancing control and helping preserve brake integrity under demanding off-road conditions.

Additionally, unlike many modern diesel systems, these engines can run on both high and low sulfur diesel fuels—providing added convenience for remote travel, including destinations like Baja California. Additionally, if you're eco-minded and love a little DIY, why not run your diesel Delica on recycled cooking oil? With the correct fuel lines, a winter-ready tank, and a few tweaks, you’ll be rolling down the road with the scent of fries trailing behind you. Tasty for the planet, too.

Here are a few additional factors to consider:

DISCLAIMER: These measurements were taken in automatic transmissions. Manual transmissions will have higher RPMs at the same speeds, therefore, causing lower cruising speeds.

For fuel efficiency, the 2.5L turbo diesel 4D56 wins hands down. This engine with the Nomadic Tune can do 22 or more miles per gallon. Without our tune, the 4D56 is capable of 18-20 MPG. In stock format, this engine will be limited in its cruising speed which is around 65 MPH. So, you’ll need to harness some patience on long highway road trips and add an hour to the projected google maps time. Mind you, on mountain roads with a speed limit of 55 mph, the 4D56 shines bright while mostly keeping up with traffic. After our tune, the van feels more like a modern car, increasing acceleration by more than 35%. Visit our YouTube page and watch the Stage 1 Tune video for a rundown with Rondo.

Stock 4D56 Specs:

  • 86 HP

  • 132 lb. ft. torque

  • Cruising Speed of 65 MPH at 2650 RPM

For performance versatility, the 4M40 2.8L Turbo Diesel is the best pick. It nearly matches the L300’s 4D56 fuel efficiency and the L400’s 6G72 top speed, while delivering the most balanced performance overall. From a standstill, the 4M40 delivers responsive acceleration thanks to its quick turbo spool at low RPM, minimizing lag and maximizing boost delivery during initial throttle input. With proper tuning—involving optimized fueling and injection timing—the engine can achieve fuel economy in the low 20 MPG range. Stock, the engine performs quite well, with some tweaks, it performs on a whole new level. To ensure engine long-term reliability, we keep boost levels moderate and make sure the temperatures stay well within tolerance.

The facelifted Series 2 L400s’ fuel injection pump is electronically controlled and harder to tune above a certain level. Expect similar fuel economy to the Series 1 but don’t expect to match the same maximum power output as the original 4M40.

Stock 4M40 Specs:

  • 130 HP

  • 213 lb. ft torque

  • Cruising Speed 80 MPH at 3,300 RPM

For sustained highway speeds, the 3.0L V6 6G72 gasoline engine, found in the L400, performs notably better than its counterparts. If your usage includes long-distance travel or frequent highway driving, this powertrain may be the most suitable option. While the 6G72 lacks the torque of the 4M40 diesel, it remains a capable performer off-road. Fuel economy with the V6 typically peaks at around 18 MPG.

An added advantage is parts availability: since the 6G72 was featured in multiple USDM vehicles, components are easier to source across the United States and tend to be more cost-effective than diesel alternatives.

Stock 6G72 Specs:

  • 195 HP

  • 205 lb. ft. torque

  • Cruising speed of 80 MPH at 3,550 RPM (will happily go faster)

This leaves the last option, which is available in the L400 and L300, the gasoline powered 4G64 2.4L SOHC 8 Valve. As a less common and minimally tunable engine, it’s the least favored option—offering lower performance and fuel efficiency than the 4D56. While viable, meaningful upgrades require extensive and costly modifications like internal overhauls and turbocharging. Nomadic does not currently offer performance upgrades, other than exhaust, for this powerplant. That being said, this engine was released in multiple Mitsubishi and Diamond Star Motors vehicles in the 90’s and early 2000’s; such as the Dodge Ram 50 truck, the Montero and certain versions of the Eclipse like the Spyder. So, its parts and support are more commonly available across the United States, making this an option to consider.

Stock 4G64 Specs:

  • 112 HP

  • 117 lb. ft. torque

  • Cruising Speed of ~65 MPH (similar limitations to the stock 4D56)

This leads us into another important comparison between the engines: Reliability.

Delica L300 vs L400 Reliability

Is the Mitsubishi Delica reliable?

Yes, the Mitsubishi Delica is very reliable when properly maintained. You can expect to get 400,000 KM or more out of any of the Delica’s engine options. There are some key differences between both the L300 and L400 engine options.

L300 vs L400 Reliablility

There isn’t much objective data covering the Delica's reliability. But from our extensive first-hand experience with these engines, we do see some patterns.

Overall, both the L400 engines, 4M40 and 6G72, are going to be less fussy and more reliable. Their placement under the hood allows them to shed heat more efficiently, which adds to their longevity. The 6G72 engine, in particular, is generally reliable due to its simplicity as a single overhead camshaft design actuating 12 valves on each bank. Respectively, this is the least complicated V6 that Mitsubishi ever made and is less prone to complex issues, making it a more approachable option for individuals unfamiliar with gasoline engines.

Both the 4D56 and 4M40 diesel engines in the Delica require a well-maintained cooling system to ensure reliability. Inadequate coolant levels or incorrect coolant mixtures can lead to overheating and potential head gasket failures—issues that are particularly prevalent in the L300’s 4D56 variant. This is why we inspect the cooling system in detail during our Maintenance Routine. Cooling system components and oil seal replacements are common services for these engines upon their first visit with Nomadic. In extreme circumstances, we integrate hyper-cooling radiator systems into the existing passageways of the Delica to ensure their reliability during the hot summer months. Like with any vehicle, ambient outdoor temperature directly effects the engine’s performance. To keep track of engine diagnostics on-the-fly, we prefer to install a dash mounted gauge which digitally tracks turbo boost, coolant temperature and exhaust temperature. This ensures that the driver can see accurate live data and know when to adjust their driving approach. Keeping up with general maintenance, checking your fluids and looking for leaks under the van regularly, is key when owning any used vehicle.

In Terms of transmissions, we’ve only had to rebuild two L300 automatics, one L300 Manual 5 speed and only one L400 Automatic. Since we’ve sold and maintained hundreds of these rigs, we’d say that’s pretty impressive on Mitsubishi’s part. As for the L400 5 speed manual, we haven’t rebuilt one yet but we have an extra in storage, just in case; Knock on wood. Luckily, most every piece of the drivetrain for both variants including brake system components, u-joints, CV axels, transmission parts, shocks, and more can be sourced within North America. For those of you trying to turn your Delica into a monster, keep in mind that with super large lifts and 35” tires, you’ll stress the transmission and transfer cases much more. Stay out of overdrive and in high RPM if you’re climbing steep terrain and watch your transmission temps. With massive tires, another upgrade you may want to consider upgrading to a set of 5.29 gears but that’s only for the serious off-roaders.

Outside of engine and transmission reliability, both chassis are very reliable, and known for their robust design. Aside from rust, there isn’t much to be worried about here. Both versions of the van are unibody with multiple subframes, which keeps them lightweight. Make sure to wash the undercarriage after offroading and especially if you’ve been near the coast or driving on sand.

If you are purchasing from Nomadic Vans, you can rest assured that all of these issues have been checked for and repaired. Check out the Maintenance Routine page for more information!

Which Delica is best Off-Road? 

Both models are equipped with 4WD options, making them capable of handling a variety of terrain. The L300 is particularly known for its robust off-road performance, while the L400 offers a more balanced approach with improved handling and comfort. Both have practically the same independent suspension up front with torsion bars, which eat-up washboard roads with ease. The real differences are in their transfer case and rear suspension.

For off-road performance, you can’t go wrong either way. While the L400 tends to get preference in other countries (Australia and Canada), probably for it’s center locking 4WD system, stronger engine and rear wheel disc brakes, the L300 tends to be the favorite in the States possibly because of its similar feel to a CJ-5 Jeep.

Delica L300 Off-Road Performance

Stock, the L300 does have more room in the fenderwell to clear a larger tire. 31 inch tires will clear without a lift and some fenderwell trimming. This puts the side skirts 18.5” off of the ground, making it quite hard to high center the van with its 88” wheelbase. The two speed transfer case allows for some low-speed crawling while maintaining high rpm power. The rigidity of the rear leaf springs keeps the L300 strong but lack the articulation that some would prefer. Maneuverability with its turning radius is unbeatable as well as its cab-over driver position, for optimal visibility. Its front approach angle is by-far the best, not only compared to the L400 but 90% of overlanding vehicles everywhere. Let us not forget that a majority of early generation Starwagon’s came a limited slip rear differential which adds an immense amount of control on slippery surfaces.

Many of these off-road advantages, however, will translate into less on-road comfort and capability.

Delica L300 Weights: Note how much less the L300 weighs compared to its younger brother

  • L300 4D56 (hardtop) | 4,034 LBS

  • L300 4G64 (hardtop) | 3,836 LBS

  • L300 4D56 (Crystal Lite Roof) | 4,184 LBS

  • L300 4G64 (Crystal Lite Roof) | 3,986 LBS

Delica L400 Off-Road Performance

The L400 also performs admirably off-road, with better suspension and handling due to its 4WD system improvements. The shift-on-the-fly transferase is convenient for high range 4WD when headed up the pass for a ski adventure when the snow starts to fall. The L400 will be somewhat heavier and have less clearance than the L300, stock. What the L400 lacks for clearance with a 30” tire, it makes up with power and more modern suspension. It’s coil spring rear suspension absorbs more rough terrain and allows for more articulation during more challenging rock crawling. The center locking differential is known to pull drivers out of some lack-luster situations in the mud and snow. Limited slip differentials are rarely found in L400’s from the factory but they do exist. Of course, drivetrain upgrades are available to make this rig even more capable, if you’re considering a more serious overlanding adventure, like the Rubicon.

The L400 strikes a balance between on-road comfort and off-road capability, making it suitable for those who want a versatile vehicle that can handle a variety of driving conditions without sacrificing comfort.

Delica L400 Weights: More power with slightly more weight

  • SWB L400 4M40 (Hardtop) | 4,343 LBS

  • SWB L400 6G72 (Hardtop) | 4,255 LBS

  • SWB L400 4M40 (Crystal Lite Roof) | 4,585 LBS

  • SWB L400 6G72 (Crystal Lite Roof) | 4,497 LBS

  • LWB L400 4M40 (Crystal Lite Roof) | 4,718 LBS

  • LWB L400 6G72 (Crystal Lite Roof) | 4,630 LBS

Delica Trim Levels and Interiors

Both the L300 and the L400 came in a myriad of options and trims. Many of them overlapping. It is hard to include every little nuance between these trims, but below is the most relevant information and differences. They came with “Crystal Lite Roofs” on Exceed and Super Exceed models. These ceilings of glass are quite the experience, but in rare occasions, it should be noted that they can be prone to issues if the seals begin to go stale. Another option was the cold-weather package, which came with more insulation, and sometimes a dual battery setup. The cold-weather package came standard on the Chamonix/Mont Blanc and Jasper trim levels, because these were marketed as vans for winter sports enthusiasts. Lots came with incredible side graphics, some saying, “Designed for the all-season, outdoor player.” no matter the Delica you choose, rest assured you’ll never see another with the same options from the factory. They are all unique characters.

Delica L300 Trims

Delica L300 Chamonix Edition

There are more L300 trims than what is listed here, especially across different markets. These are the most relevant to the Japanese market and US imported market.

  • GLX - The L300’s base model. There are lower trims than this, but, typically the lowest trim level you will find imported into the United States is the GLX. Standard cloth seats and plastic side panels. Standard rotating bench-style second row seats.

  • Exceed - Upgraded interior from the GLX. Velour seats with more cushion. Captain’s chair style second row seats that swivel around for multiple configurations. Came with either a high or low hardtop roof or an optional crystal lite roof.

  • Super Exceed - The highest trim level offered. The Super Exceed came with alcantara upholstered seats, flocked window and door trim. This trim had the same captain’s style second row seats and a thicker carpet. The Super Exceed only came in an automatic with the Crystal Lite Roof, as far as we’ve seen. As a bonus, an LSD was found in every single Super we’ve imported.

  • Chamonix (1989-1994) - Named after the iconic ski destination in France, the Chamonix was a special edition Delica GLX marketed towards skiers and cold weather applications. This trim came with an LSD, a high-roof with built in insulation, a dual battery compartment, and an alternative interior color with standard bench style second row seats. This trim came in a variety of colors and graphics. The crystal lite roof was not an option.

  • Jasper (1993-1994) - Named after Canada’s expansive National Forest, the Jasper came out as the next iteration to the Chamonix trim level. It had largely the same upgrades as the Chamonix. The only difference being the different exterior/interior colors and graphics. The crystal lite roof was not an option.

  • Active World (1996-1997) - A replacement for the Chamonix and Jasper. Why they didn’t name this edition the “Nagano” after the Olympic games happening at the time, I do not know. The cold-weather package was not standard, and this model was available with a high or low hardtop roof (no crystal lite roof option). Some Active World’s came with the came with the dual battery setup. Alternative patterned upholstery compared to the GLX, similar to the Chamonix and Jasper.

Delica L400 Trims

Similar trim options to the L300 with some exceptions.

Delica L400 Super Exceed

  • XG - This was the base model of the L400. Not very common in the United States. Came with swiveling bench-style seats (cloth).

  • Exceed - Velour upholstered seats. Captain’s chair style second-row seats. High or low hardtop, or optional crystal lite roof on high tops only. Padded cloth side paneling.

  • Super Exceed - Upgraded seats with more cushion. Thicker floor carpeting. Crystal Lite Roof option standard. The LSD was NOT released in every Super, unlike the L300. Rear cabin 12 V light with corded attachment and electronic fold away side mirrors optional.

  • Royal Exceed (LWB only) - Same as the Super Exceed but long wheelbase only and came with an optional karaoke machine, heated seats, Electronic fold away side mirrors, Limited Slip Rear differential, Electric driver seat and many more features. We’ve only seen them with a Navy blue exterior.

  • Chamonix/Mont Blanc - Special edition L400 with swiveling bench-style second-row seats. The cold-weather package came standard. Hardtop only with a high or low roof option. Sometimes came with dual battery compartment and rarely an LSD. Series 1 L400s came with blue patterned cloth seats. Series 2 came with tan or white leather bench second-row seats and a white paint option.

  • Jasper - Same as Chamonix, but with different exterior and interior graphics and only a cloth seat option.

Final Verdict

Choosing between the L300 and L400 ultimately depends on your priorities, as both are highly capable adventure vehicles with distinct strengths. The L300 offers classic retro styling, a fuel-efficient powertrain, and a compact cab-over chassis that lends itself well to off-road maneuvering. While off-road performance is comparable between both models, the L300 may hold a slight advantage in technical terrain.

The L400, on the other hand, provides a smoother on-road experience and higher cruising speeds, thanks to its refined suspension and more conventional layout. Many buyers gravitate toward the Spacegear variant for its newer build, enhanced safety features, and the robust 6G72 V6 engine—widely supported by U.S. auto shops due to its presence in numerous domestic vehicles.

For mechanically inclined enthusiasts, the L300 remains a compelling option. However, owning any older vehicle—Delicas included—requires a practical understanding of its quirks and respectful upkeep, despite its famously reliable Japanese engineering.

Both models have much to offer, and neither is a wrong choice. We hope this guide supports your decision in finding the best match for your adventures. If you have additional questions, don’t hesitate to reach out or leave a comment—our team is always happy to assist!
