Inside the 2026 Hyundai IONIQ 5: Space, Sustainable Design, and a Cabin That Earns the Commute

The 2026 Hyundai IONIQ 5 uses its dedicated E-GMP electric platform to eliminate the center floor tunnel entirely, opening up a flat-floor cabin that feels a full class larger than the exterior suggests. Built on a 118.1-inch wheelbase, it seats five with rear-row legroom that rivals many larger family SUVs. For St. Louis households covering daily South County commutes and weekend hauls alike, the IONIQ 5 interior answers practical space questions as convincingly as any electric SUV at its price point.

Seating and Passenger Space

Five passengers fit across two rows, with front occupants sitting in a wide, airy space with approximately 41.7 inches of legroom and generous headroom that accommodates taller drivers without compromise. The flat floor is the cabin’s defining feature: there is no center hump pushing the middle rear passenger awkwardly onto a tunnel, and rear legroom approaches 40 inches. Rear seats recline and slide forward and backward, letting passengers adjust between maximum legroom and extra cargo depth depending on what the trip demands. Dual-zone automatic climate control is standard across the lineup, as are rear AC vents and dual USB charging ports for back-seat passengers, keeping a full family comfortable on a longer run toward the Lake of the Ozarks or across Missouri.

Cargo Space and Versatility

Behind the rear seats, the IONIQ 5 delivers 26.3 cubic feet of cargo space — enough for a full grocery run or a weekend bag for each passenger. Fold the second row flat and the number expands to 58.5 cubic feet of usable, low-liftover load floor, wide enough to handle flat-pack furniture, bike frames, or gear for a camping trip down I-55. The sliding rear seat adds a layer of flexibility most rivals do not offer: trade a few inches of rear legroom for extra cargo depth when you need it, then slide it back for passengers when you do not. Out front, a 0.85-cubic-foot front trunk holds the charging cable and CCS adapter cleanly, freeing the main cargo area for everything else.

Interior Materials and Comfort

Hyundai built the IONIQ 5 cabin with a sustainability-forward material palette: eco-processed leather, bio-based paint finishes, and recycled fiber elements throughout. 

The base SE comes with cloth upholstery; higher trims introduce H-Tex vegan synthetic leather that reads and feels premium without conventional hides. Interior color schemes run toward sophisticated dark tones, with black and gray-on-gray combinations available across the lineup. Heated front seats are standard on every trim, a meaningful feature during Missouri winters. 

The Limited steps up with ventilated front seats, heated rear outboard seats added for 2026, and a power-extendable leg rest on the driver’s seat. That trim also unlocks the Universal Island center console, which slides forward or backward to suit driver reach or rear-seat access — a practical detail that makes more difference in daily use than it sounds on paper.

Cabin Technology

Two 12.3-inch displays share a single horizontal housing across the dashboard: a digital instrument cluster on the left and the ccNC touchscreen on the right. One of the IONIQ 5’s understated strengths is that Hyundai kept audio volume and tuning on physical knobs and gave climate control its own separate panel, rather than burying both inside the touchscreen. That keeps eyes on the road and hands on familiar controls during a St. Louis commute. Wireless Apple CarPlay and Android Auto are standard, with wireless phone charging and the Hyundai Digital Key added at the SEL trim. The XRT and Limited upgrade to an eight-speaker Bose audio system, and Limited buyers gain a head-up display that projects speed and navigation data directly onto the windshield.

Interior equipment varies meaningfully across the IONIQ 5 trim lineup, from the heated-seat SE to the ventilated-seat, sliding-console Limited. Our team at Suntrup Hyundai South can walk through which configuration matches your daily needs and budget.

A flat floor and a dual-screen dashboard describe what the 2026 IONIQ 5 cabin contains, but the feel of 40 inches of rear legroom, the texture of the eco-leather surfaces, and the quiet that fills the cabin at highway speed are things that come through in person. Suntrup Hyundai South carries the full 2026 IONIQ 5 lineup at our South Lindbergh Boulevard location, and every trim is available for a test drive.
