If your daily routine puts you on I-85 between Spartanburg and Greenville, the question isn't which compact sedan photographs better in a brochure. The real test is which one makes that run easier, cheaper, and less fatiguing over the long haul. We've spent real time with both cars here at Steve White Volkswagen Spartanburg, and the fair answer is they're genuinely different tools built for slightly different drivers. One of them probably fits your commute better than the other, and it isn't always the one you'd guess.
Start with the bottom line. The 2027 Volkswagen Jetta wins on highway fuel economy, rear legroom, and standard safety tech at every trim level. The 2026 Mazda3 wins on available AWD, a sportier feel at the wheel, and a premium cabin vibe in its higher trims. Neither is the wrong answer. They're just not equivalent answers.

How far will your commute budget go in each car?
The number that shapes everything else for a daily driver is how much fuel the car drinks over a year of commuting, and on that measure the 2027 Jetta pulls clearly ahead of the Mazda3 once you point it down the interstate. The EPA rates the 2027 Jetta at 29 city / 40 highway mpg on regular 87-octane gasoline, and that 40-mpg highway figure holds across all four standard trims (S, Sport, SE, and SEL). No cherry-picked number from the lightest trim on the most favorable test cycle. The figure stays consistent.
The 2026 Mazda3 sedan with the naturally aspirated 2.5-liter engine lands at 27 city / 36 highway / 30 combined mpg, per EPA ratings. Still solid. But the highway number trails by 4 mpg, and the highway is where Upstate SC commuters actually spend their time.
| Spec | 2027 Volkswagen Jetta (S/Sport/SE/SEL) | 2026 Mazda3 Sedan (2.5 S FWD) |
|---|---|---|
| Engine | 1.5L turbo 4-cylinder | 2.5L naturally aspirated 4-cylinder |
| Horsepower | 158 hp | 186 hp |
| Torque | 184 lb-ft | 186 lb-ft |
| Transmission | 8-speed automatic | 6-speed automatic |
| EPA City mpg | 29 | 27 |
| EPA Highway mpg | 40 | 36 |
| EPA Combined mpg | 33-34 | 30 |
| Fuel grade required | Regular (87) | Regular (87) |
| Rear legroom | 37.4 in | 35.1 in |
| Trunk volume | 14.1 cu ft | 13.2 cu ft |
| Standard safety suite | IQ.DRIVE (all trims) | i-Activsense (all trims) |
| AWD available | No | Yes (select trims) |
The Mazda3 does have more horsepower (186 vs. 158), and you'll feel it if you like a spirited merge onto I-85. The engine of the Jetta delivers its 184 lb-ft of torque low in the rev range, which feels more useful in stop-and-go Reidville Road traffic than a naturally aspirated engine that needs revs to get moving. Both cars run on regular fuel, so you're not paying a premium for performance.
Where does each car put its passengers?
Both sedans seat four adults comfortably up front, but the back seat is where they separate, and the Jetta wins it by a clear margin thanks to a couple of extra inches of rear legroom you can feel on a longer ride. The Jetta has 37.4 inches of rear legroom. The Mazda3 sedan comes in at 35.1 inches. That 2.3-inch difference doesn't sound like much until you've been the person in back on a 45-minute commute.
If you're carpooling coworkers, shuttling kids from Wofford College or USC Upstate on weekends, or just regularly putting two adults in the back, the Jetta is noticeably roomier back there. The Mazda3's interior quality is excellent, and the materials feel a step above base trims of the Jetta, though it fits the back seat tighter. We'd call that a real tradeoff worth weighing.
Trunk space also favors the Jetta, 14.1 cubic feet versus 13.2 in the Mazda3 sedan. Neither is cavernous, but the Jetta gives you a bit more room for groceries, gym bags, or gear when you're heading toward SC Highway 11 and the Cherokee Foothills for the weekend.
What safety technology comes standard?
Both cars take standard safety tech seriously, and each one ships its full driver-assist suite on the base trim rather than locking the good features behind a pricier upgrade, so you start protected no matter which sedan you drive home. Every trim of the 2027 Volkswagen Jetta comes with IQ.DRIVE. The suite of Volkswagen includes adaptive cruise control with stop-and-go, forward collision warning with automatic emergency braking and pedestrian monitoring, lane-keeping assist, active blind-spot monitoring, and rear traffic alert. You don't have to pay to unlock it on a higher trim. All of it rides on the base S.
The 2027 Volkswagen Jetta also earned a five-star overall safety rating from NHTSA. For commuters logging serious highway miles, that rating is meaningful context.
The honest case for the Mazda3
We'd be doing you a disservice if we only pressed the case of the Jetta here, because the Mazda3 earns real consideration in two specific situations where it clearly outpoints the Jetta, and both are worth naming plainly before you decide. First, if you want available AWD, the Mazda3 Carbon Edition and Turbo Premium Plus trims offer all-wheel drive through Mazda's i-ACTIV AWD system, while the Jetta has no AWD option at all. Upstate SC winters are mild by northern standards, but ice events hit I-85 every few seasons. If that truly worries you, the Mazda3 is the only one of these two that can address it.
Second, the drive can matter as much as the destination. The Mazda3 has a more engaging steering feel and a sportier suspension tune. It won't pretend to be a performance car, but next to the composed, comfortable highway ride of the Jetta, the Mazda3 is the more entertaining machine on a winding road. The Jetta is tuned to make 40,000 miles of I-85 feel easy. The Mazda3 is tuned to make those miles feel a little more alive.
Personal preference drives that call.
Plan your decision this way
Choosing between these two really comes down to how you weight highway efficiency and back-seat space against all-weather grip and steering feel, and here's the simple framework we'd hand a Spartanburg driver standing on our lot and trying to decide which sedan to take home.
Pick the 2027 Volkswagen Jetta if: highway fuel economy is your top priority, you regularly carry adults in the back seat, you want every safety feature included without a trim upgrade, or you want a 40-mpg German-engineered sedan with a roomy trunk and a composed long-haul ride.
Pick the 2026 Mazda3 if: you want available AWD for the occasional icy Upstate SC morning, you care about a more spirited driving feel, or you want the premium interior quality that Mazda's higher trims deliver.
We'll make one concession plainly. The Jetta doesn't offer AWD. For most Spartanburg commuters on I-85, front-wheel drive with 40 mpg highway is the better everyday trade. But if AWD matters to you, the Jetta isn't your car, and we'd rather tell you that than sell you the wrong one.

Frequently Asked Questions
Does the 2027 Volkswagen Jetta get good gas mileage for a daily commute?
Yes. The EPA rates the 2027 Volkswagen Jetta at 29 mpg city and 40 mpg highway on regular 87-octane fuel, across all four standard trims (S, Sport, SE, and SEL). That 40-mpg highway figure holds no matter which trim you choose, and it runs on regular gasoline, not premium. For Spartanburg commuters putting real miles on I-85, that figure ranks among the strongest highway efficiency numbers in the non-hybrid compact sedan segment.
Does the Volkswagen Jetta have more backseat room than the Mazda3?
It does. The 2027 Volkswagen Jetta offers 37.4 inches of rear legroom, compared to 35.1 inches in the 2026 Mazda3 sedan. That 2.3-inch difference shows up in real use, especially if you're regularly carrying adults in the back seat for a commute or weekend run toward the Blue Ridge foothills. The trunk of the Jetta also runs slightly larger at 14.1 cubic feet versus 13.2 in the Mazda3 sedan.
Is the Mazda3 a better choice if I want AWD?
If AWD is a real priority for you, the Mazda3 is the right pick between these two. The 2026 Mazda3 offers Mazda's i-ACTIV all-wheel drive on its Carbon Edition and Turbo Premium Plus trims. The 2027 Volkswagen Jetta is front-wheel drive only. No AWD option exists in the Jetta lineup. For most Spartanburg-area commuters, front-wheel drive with 40 mpg highway handles the daily routine well. But if Upstate SC ice conditions are a real concern for you, the Mazda3 addresses them and the Jetta does not.
