Best Vans for MPG in 2026

Fuel economy in the van world splits into two conversations that rarely belong in the same list: minivans built for families, and full-size cargo vans built for business use.

They don’t compete against each other, so this breaks them apart instead of ranking them together.

It’s also worth knowing upfront which vans simply aren’t buyable new anymore. The Dodge Grand Caravan stopped production in 2020. The Chevy City Express died in 2018. The Nissan NV200 was discontinued in 2021.

None of those show up on a dealer lot in 2026, no matter how good their MPG numbers looked on paper a few years back.

Minivans: the real fuel-economy leaders

Toyota Sienna — 36 mpg combined

The Sienna has been hybrid-only since this generation launched in 2021, and it’s still the class leader by a wide margin.

City and highway both land at 34–36 mpg depending on trim, and AWD is available without much of a fuel-economy penalty since the system uses a second electric motor on the rear axle rather than a mechanical driveshaft. Pricing starts around $40,420.

The tradeoff owners bring up most often isn’t mileage — it’s the sound of the hybrid system under hard acceleration, which several reviewers and owners describe as intrusive on highway on-ramps.

Kia Carnival Hybrid — 32 to 33 mpg combined

New for the 2026 model year, the Carnival Hybrid closes most of the gap to the Sienna while keeping the Carnival’s class-leading cargo space — 145.1 cubic feet with all seats folded, versus the Sienna’s 101 cubic feet.

The non-hybrid V6 Carnival is a different story entirely: 18 mpg city and 25 mpg highway, well behind both the Sienna and its own hybrid sibling.

If gas mileage matters to you at all, the Carnival is only worth cross-shopping in Hybrid trim.

Chrysler Pacifica Hybrid — 29 to 30 mpg combined (gas), up to 84 MPGe

The Pacifica Hybrid is the only plug-in minivan on sale, and it plays a different game than the Sienna or Carnival: up to 32 miles of pure electric range before the 3.6-liter V6 kicks in, at which point it settles into a 29–30 mpg combined rating.

For families with a short commute and a driveway charger, a lot of weekly driving could happen on electricity alone.

The non-hybrid Pacifica V6 is considerably thirstier — 22 mpg combined FWD, dropping to 20 mpg with AWD.

Honda Odyssey — 22 mpg combined

The Odyssey brings up the rear on fuel economy with no hybrid option at all, just a 3.5-liter V6 and a 10-speed automatic.

What it trades away in mpg, it makes up in third-row comfort — the Magic Slide second-row seats and wider third-row bench are frequently cited by owners as the best in the segment for actual adult passengers on road trips, not just kids.

Full-size cargo vans: a completely different fuel-economy conversation

Nobody cross-shops a Ford Transit against a Toyota Sienna, but it’s worth explaining why the fuel-economy numbers look so different between the two categories.

Cargo vans haul heavier loads, have worse aerodynamics, and — critically — the Ford Transit no longer offers a diesel engine at all for 2026. It’s gas-only: a 3.5-liter V6 or the EcoBoost twin-turbo version, both through a 10-speed automatic.

Mercedes-Benz Sprinter — 18 to 24 mpg

The Sprinter remains the only diesel option among the three major full-size vans, and it shows at the pump: real-world reports put it at 18–24 mpg depending on load and driving style, ahead of both gas competitors.

It also carries a $6,000-plus price premium at the entry level over the Transit, and one commercial-fleet comparison calculated that premium takes over 12 years of fuel savings to recoup on a typical duty cycle — worth factoring in if mpg is your only reason for choosing it.

Ford Transit — roughly 15 to 19 mpg

Rear-wheel-drive Transit models with the base 3.5L V6 report around 17 mpg highway in independent testing; all-wheel-drive versions with the EcoBoost engine drop closer to 13 mpg combined.

Ford’s 10-speed automatic is a genuine advantage over the ProMaster’s 9-speed, and the Transit is the only van of the three offering both AWD and a turbocharged engine, which matters more for towing than for mpg.

Ram ProMaster — roughly 14 to 19 mpg

The ProMaster runs a single powertrain across the board — a 3.6-liter Pentastar V6 making 276 hp — and it’s consistently the least fuel-efficient of the three in side-by-side testing, typically landing at 14–17 mpg loaded.

What it gives up in mpg it gives back in cargo width (its 75-inch interior is the widest in the segment) and the lowest load floor of any full-size van, since front-wheel drive eliminates the driveshaft tunnel entirely.

What’s gone, and why it matters if you’re cross-shopping used

A few names keep coming up in forum threads and secondhand listings that simply aren’t buyable new anymore.

The Ford Transit Connect and Ram ProMaster City — both efficient small cargo vans in the low-to-mid 20s mpg — are gone from the U.S. lineup, with Transit Connect production ending first and ProMaster City following shortly after; both now live only on the used market.

The Nissan NV200 and Chevrolet City Express, badge-engineered siblings under Nissan and GM, respectively, are both gone too.

And the Dodge Grand Caravan wrapped up in 2020, with Chrysler folding its cheaper-minivan role into the Voyager trim instead.

FAQs

The Toyota Sienna, at 36 mpg combined. It’s the only minivan sold exclusively as a hybrid, which is exactly why nothing else in the segment touches its number.

Functionally, yes — the Toyota Sienna, Kia Carnival, Honda Odyssey, and Chrysler Pacifica (plus its stripped-down Voyager sibling) are the only traditional minivans still sold new. The Volkswagen ID.Buzz exists too, but it’s an electric people-mover in a different price and use category entirely.

Realistically 18–24 mpg, and only from the Mercedes-Benz Sprinter’s diesel engine. Gas-only vans like the Ford Transit and Ram ProMaster land closer to 14–19 mpg depending on configuration and load.

Yes. Both the Ford Transit Connect and Ram ProMaster City are gone from the U.S. new-car market — Transit Connect was the more efficient of the two at roughly 25 mpg, but Ford pulled it, and Ram followed with the ProMaster City shortly after. Anyone shopping one now is shopping used.

Final Word

If your business runs a fleet and mpg is the deciding factor over cargo space, it’s worth checking our breakdown of PHEV SUVs as well — a plug-in SUV can sometimes out-economize even the Sprinter on mixed routes with regular charging access, depending on your daily mileage.

And if you’re leaning toward a minivan but still shopping lease offers before committing, our current SUV lease deals roundup is worth a glance before you sign anything — some of the same manufacturers running minivan promotions have overlapping SUV lease specials worth comparing line by line.
