I-65 runs straight through Hendersonville, and whether you're pointing it south toward Birmingham or north toward Louisville, you'll be on that road for three to four uninterrupted hours. That kind of drive doesn't ask for the sportiest car in the lot -- it asks for the one with a quiet cabin, a confident adaptive cruise system, honest fuel range, and enough seat comfort to feel decent when you pull off the interstate. The 2026 Hyundai Sonata brings all of that, but which configuration brings it best?
The clearest answer: the 2026 Sonata Hybrid SEL is the standout road-trip pick for most Hendersonville drivers. Its EPA-estimated 47 mpg combined means fewer stops, its standard dual-zone automatic climate control and heated front seats keep everyone comfortable past hour two, and its standard adaptive cruise with lane-centering steering handles the long straight sections of Tennessee's I-65 corridor without constant driver correction. The gas Sonata SE is a legitimate runner-up with an EPA-estimated 38 mpg highway and the same full SmartSense driver-assist suite at a lower entry point.
2026 Sonata Configurations Ranked for I-65 Road Trips
The ranking criterion is real and specific: highway fuel efficiency, cabin comfort features by trim, and driver-assist capability for multi-hour interstate driving. Here is how the 2026 Sonata lineup stacks up on all three.
| Rank | Configuration | Best For | EPA Highway MPG | Road-Trip Standout |
|---|---|---|---|---|
| 1 | Sonata Hybrid SEL | Efficiency + comfort balance | 51 combined / 44 city | Dual-zone climate, heated seats, standard HDA cruise |
| 2 | Sonata Hybrid Blue | Pure fuel efficiency | 56 hwy / 47 city | Highest highway figure in the lineup |
| 3 | Sonata SE | Value-first long-haul | 38 hwy / 28 city | Standard adaptive cruise, wireless CarPlay, 12.3-inch screen |
| 4 | Sonata SEL Sport FWD | Polished gas option | 36 hwy / 25 city | Wireless charging, 18-inch wheels, heated seats |
| 5 | Sonata N Line | Short spirited runs | 32 hwy / 23 city | 290-hp turbo -- sport-tuned for feel, not marathon comfort |
The Sonata Hybrid SEL Makes the Most Sense for Nashville-Corridor Runs
For a Hendersonville-to-Birmingham drive -- roughly 240 miles south on I-65 -- the Sonata Hybrid SEL's EPA-estimated 47 mpg combined means most drivers complete the trip without a fuel stop. The hybrid system pairs a 2.0-liter four-cylinder with an electric motor for 192 combined horsepower, routed through a six-speed automatic transmission tuned for smooth, settled highway pulls rather than sporty downshifts. That matters after two hours of steady cruising.
The SEL trim delivers the comfort package that makes multi-hour driving manageable: dual-zone automatic climate control, heated front seats, and a power-adjustable driver's seat. In July on I-65 through Alabama, dual-zone climate control is not a luxury trim -- it is the feature that keeps the return argument about temperature from starting. The Sonata Hybrid carries 16 cubic feet of cargo capacity with 60/40 split-folding rear seats, which is enough for two carry-on-sized bags and a cooler without rearranging on the side of the road.
Every 2026 Sonata comes standard with Hyundai's full SmartSense suite: adaptive cruise control, lane-centering steering, blind-spot monitors, rear cross-traffic alert with automatic braking, and a driver attention warning. Per Hyundai, the lane-centering steering actively corrects toward the lane center on highway curves, reducing the micro-corrections that accumulate into driver fatigue on long straight interstate sections.
The Sonata SE Makes a Straightforward Case for Long-Haul Value
The gas Sonata SE deserves more credit than base-trim framing usually gives it. Hyundai's EPA rating for the 2026 Sonata SE is 28 city / 38 highway / 32 combined mpg -- solid highway numbers that keep a Hendersonville-to-Louisville run (about 175 miles) well within range on a single tank. The 2.5-liter four-cylinder makes 191 horsepower and 181 lb-ft of torque, paired with an eight-speed automatic that holds a relaxed cruising RPM at highway speeds.
The SE comes standard with a 12.3-inch touchscreen, wireless Apple CarPlay and Android Auto, and two rear USB ports -- the practical details that matter when four people share a car for three hours. Standard adaptive cruise control and lane-departure steering assist are included at this trim level, so the highway-assist features are not gated behind a trim upgrade. The tradeoff is cloth seating and manually adjustable front seats; a taller driver doing a four-hour I-65 run should spend five minutes finding their preferred seat position before leaving Hendersonville rather than at a rest stop near Spring Hill.
Pros and Cons of the 2026 Sonata Hybrid for I-65 Drives
| Pros | Cons |
|---|---|
| EPA-estimated 51 mpg combined (Blue) reduces fuel stops on long runs | Hybrid Blue has manually adjustable front seats; no power driver's seat |
| Standard adaptive cruise with lane-centering on every trim | No AWD option on any Sonata Hybrid configuration |
| Quiet, refined cabin noticeably reduces fatigue past hour two | Cargo space (16 cu ft) is less than some midsize sedan competitors |
| Dual-zone automatic climate standard on SEL and Limited | Six-speed automatic feels less crisp than the gas SE's eight-speed unit |
| 60/40 split-folding rear seats for flexible luggage loading | Power-gas handoff can feel slightly less seamless than Toyota's system |

The Sonata Hybrid Limited Adds the Features That Matter Most on a July Drive
The Sonata Hybrid Limited adds the features that make a July I-65 drive a different category of experience. Ventilated front seats join the heated ones -- meaning seat cooling joins seat heating in a configuration that actually covers both a November Nashville-to-Louisville run and an August Nashville-to-Gulf Shores one. The Limited also adds a 12-speaker Bose audio system, a head-up display, rain-sensing windshield wipers, and a 360-degree camera system useful when navigating rest-stop parking with a full car.
The Limited introduces Highway Driving Assist, which Hyundai describes as a navigation-linked adaptive cruise that reads map data to anticipate curves and grade changes and adjusts speed accordingly -- a meaningful step up from standard adaptive cruise on the rolling section of I-65 between Nashville and the Kentucky border. The EPA-estimated fuel economy on the Limited is 44 city / 51 highway / 47 mpg combined, a modest step down from the Blue's 47 city / 56 highway / 51 combined -- the tradeoff for the added equipment. Both remain strong highway figures for a midsize sedan. See available Sonata Hybrid inventory at Hallmark Hyundai Hendersonville.
