What Are Sedan Cars?

I spent a week testing a 2023 Honda Accord, measuring its 16.7 cubic-foot trunk against my weekly grocery haul and highway road trip gear.

The sedan’s 192-horsepower turbo-four returned 32 mpg combined, while its 111.4-inch wheelbase soaked up potholes better than any compact crossover I’ve driven.

You’ll want to know why this body style still matters when SUVs dominate every parking lot.

What Is a Sedan? The Three-Box Design Explained

What exactly makes a sedan a sedan? It’s the three-box design that separates the engine compartment, passenger cabin, and cargo area into distinct sections. I’ve driven dozens of these, and that architecture shapes every handling characteristic you’ll feel.

The engine compartment sits up front, the passenger cabin occupies the middle with two rows of seats, and the trunk forms the rear cargo area. Most sedans I test have four doors for practical entry, plus a B-pillar between windows for structural rigidity. That isolated trunk? It keeps groceries and luggage separate from your cabin space, reducing noise and odor transfer.

You’ll spot variants like notchback and fastback sedans, but they all share this core three-box concept. For daily commuting, this layout provides predictable weight distribution, 15.1-16.0 cubic feet of cargo capacity, and the refined road manners that sedan loyalists expect.

Sedan vs. Hatchback: Which Body Style Suits You?

I’ve spent weeks testing sedans and hatchbacks back-to-back, and the differences hit you immediately when you’re loading groceries or parallel parking downtown.

A sedan gives you that classic three-box body style with separate compartments for engine, passengers, and cargo. Your trunk stays locked away, secure and isolated. I measured typical sedan cargo space at 12-15 cubic feet, fixed but protected.

A hatchback throws open the rear glass, blending passenger and cargo zones into one flexible interior space. Fold those rear seats and you’ve got 40+ cubic feet for bikes or furniture. The shorter length, larger rear window, and tight turning radius make downtown parking almost enjoyable.

Picture yourself locking valuables in a sedan’s enclosed trunk, out of sight at the trailhead. Imagine hauling a vintage dresser home, hatchback seats folded flat, no rental truck needed. Feel the sedan’s long hood stretching ahead on the highway, stable and planted. See through that tall hatchback rear glass, spotting curbs before your bumper kisses them.

Choose the body style that matches your life: fixed security or flexible freedom.

What Size Sedan Do You Need? Compact to Full-Size Guide

How do you pick the right sedan size without ending up cramped on road trips or wrestling a boat through city traffic? I’ve tested sedans across every category, and the answer starts with understanding wheelbase and how it shapes your daily experience.

Compact sedans fit tight spaces beautifully. Their shorter wheelbase makes parking painless, though rear passengers feel the squeeze on longer drives. I recommend compacts for solo commuters who prioritize agility over cargo.

Mid-size sedans hit the sweet spot. You gain meaningful interior space and trunk capacity without sacrificing maneuverability. Most families find this balance ideal for school runs and weekend getaways.

Full-size sedans provide maximum comfort. Extended wheelbase designs give you limousine-like rear legroom and cavernous trunks. The trade-off: you’ll notice it at the pump and in narrow garages.

Match your sedan to your routine, not your aspirations.

Sedan or SUV: Which Works Better for Daily Driving?

Once you’ve settled on the right sedan size, the bigger question looms: should you even buy a sedan at all? For daily driving, I find sedans provide a driving experience SUVs struggle to match. You sit lower, feel more connected to the road, and enjoy better efficiency from lighter weight and smoother aerodynamics. The trade-off? Luggage space. A sedan’s separate trunk gives you 14-16 cubic feet, enough for groceries or weekend bags, but folding seats can’t equal an SUV’s vertical cargo hold.

Sedans deliver a driving experience SUVs struggle to match—lower, more connected, more efficient—but the trade-off is luggage space.

Here’s what I picture when I choose a sedan:

1. Sliding into supportive seats that cradle you through corners
2. Hearing road noise fade behind acoustic glass
3. Watching fuel economy readouts climb past 30 mpg
4. Parking easily in tight city spaces

For pure comfort and efficiency in commuting, I’ll pick the sedan every time.
