2026 Chevrolet Trailblazer on I-77 in South Carolina during a summer morning commute

The Blythewood-to-Columbia run on I-77 covers about 18 miles of mostly open interstate. So highway MPG is the number that actually moves your wallet, and we won’t spend much time on city ratings for a stretch like this. Our team at Wilson Chevrolet ranks the four 2026 Chevrolet models we think fit this corridor best, starting with the 2026 Trailblazer, which earns the top spot on the strength of Chevrolet’s own EPA-estimated 31 mpg combined with the 1.3L turbo and front-wheel drive.

The 2026 Chevrolet Commuter Rankings at a Glance

If you want the short version, four 2026 models cover this corridor well, and highway MPG is what separates them, because your daily run south toward Columbia doesn’t spend much time off the interstate. All figures are EPA estimates from Chevrolet and the EPA.

The Trailblazer Wins the Efficiency Argument

Chevrolet rates the 2026 Trailblazer at 31 mpg combined with the 1.3L turbo engine and front-wheel drive, and 33 mpg on the highway specifically, which is exactly the figure that pays off when your commute runs mostly open interstate. The Trailblazer is a legitimate SUV with 54.4 cubic feet of cargo space behind the front seats, so it doesn’t feel like a penalty box just because it sips fuel carefully.

The Trailblazer does give up some ground on the spec sheet. AWD drops the combined rating to 27 mpg, and with 155 horsepower it’s not a power vehicle. But for an I-77 run from Blythewood into Columbia, that 1.3L turbo cruises at highway speed without strain. North of Blythewood, I-77 narrows to four lanes before widening again near Rock Hill. The Trailblazer’s compact dimensions make lane changes and on-ramp merges feel relaxed in that tighter corridor.

Highway efficiency plus real SUV space is why it’s our top pick here.

The Trax Is the Pure MPG Leader (With One Real Tradeoff)

The 2026 Trax is EPA-rated at 28 city and 32 highway with the standard 1.2L turbo three-cylinder, hitting 30 mpg combined, and those are genuinely strong numbers for a gas-powered vehicle. If all you’re after is spending as little as possible at the pump, the Trax wins outright.

The catch is that it’s FWD-only, with no AWD option on the 2026 Trax at all. For a purely highway commute in the Carolinas’ warmer months, that’s not a problem. But if your route includes wet-weather detours on surface roads around Blythewood or Fairfield County, or you’re hauling gear to Lake Wateree on the weekend, you’re working with front-wheel drive only. The 137-horsepower output is adequate for highway cruising but feels limited when merging under load.

Choose the Trax if you’re after raw fuel efficiency and a smaller, easier-to-park footprint. Eyes open on the AWD limitation.

Buying Caution: On any commuter purchase, cross the highway MPG figure against the miles you’re actually driving each year before you decide what the efficiency difference is worth in real dollars. A two-mpg gap becomes meaningful over 15,000 miles per year. A four-mpg gap is harder to ignore. Run the numbers on your actual commute before you walk in.
The 2026 Trailblazer (1.3L FWD) leads this ranking with Chevrolet’s own EPA-estimated 33 mpg highway, the highest of any non-electric Chevrolet SUV on our lot for the I-77 corridor.

The Equinox Is the Midsize Sweet Spot

The 2026 Equinox lands right in the middle ground between the small efficient models and the bigger family haulers, and it’s an easy balance to live with. The EPA rates it at 26 city / 29 highway / 27 combined with front-wheel drive, and 25 city / 29 highway / 26 combined with AWD.

Does AWD cost you at the pump on this route? On the highway, not really, because the rating holds at 29 mpg whether you pick FWD or AWD. The efficiency penalty of AWD shows up in city driving instead. For an I-77-heavy commute, that’s a distinction worth having.

The Equinox comes in front-wheel drive and all-wheel drive. They’re both built around the 1.5L turbo four-cylinder.

At 175 horsepower and 203 lb-ft of torque on the AWD version, the 1.5L turbo has real low-end pull. The turbo doesn’t feel stressed at 70 mph with the air conditioning running in a South Carolina August. The Equinox also offers more interior room than the Trailblazer or Trax, with 63.5 cubic feet of max cargo, so it earns its keep on weekends too.

The Equinox is the pick when you want a genuine compact SUV that doesn’t force you to choose between commuting economy and family utility.

The Traverse Earns Its Place for Carpool and Three-Row Families

Lower highway MPG doesn’t automatically knock a vehicle off this list, and the 2026 Traverse proves the point for anyone hauling kids and gear, because a three-row SUV solves a seating problem no amount of fuel savings in a smaller model can fix.

The EPA rates it at 20 city / 26 highway / 22 combined with front-wheel drive. Yes, that’s lower than every other vehicle on this list. The engine is a 2.5L turbo making 328 horsepower and 326 lb-ft of torque, which means it’s not underpowered for a large three-row SUV. It can tow up to 5,000 pounds when properly equipped. Max cargo capacity reaches 97.6 cubic feet with both rear rows folded.

The real case for the Traverse on this commute is practical. If you’re running three kids from Blythewood to their school drop-off before you hit the interstate toward Columbia, a Trailblazer seat count doesn’t solve your problem. The Traverse does.

The Traverse is the vehicle for the commuter who also happens to be running a household. We won’t pretend 22 combined mpg matches the Trailblazer. It doesn’t. But the Traverse justifies that tradeoff with genuine three-row capability at a size that fits a normal garage.
