Top 10 Mid-Size Sedans 2021 — Best Overall + Best Value

Direct Answer

For the 2021 model year, the Honda Accord is our Best Overall mid-size sedan, starting at $24,790. It pairs the roomiest trunk in the class, a genuinely engaging chassis, an available 48-mpg hybrid, and Honda's long-haul reliability into one package that does almost everything well.

Our Best Value pick is the brand-new Kia K5, starting at $23,490, which undercuts nearly every rival on price while delivering standard turbo power, available all-wheel drive, and an IIHS Top Safety Pick+ rating. If your priority is the lowest possible cost of ownership, the Toyota Camry (from $24,970) is the safest long-term bet in the group.

Below are all ten ranked, with real 2021 MSRPs, engine and EPA figures, and the trade-offs that matter.

How We Ranked the Top 10

We weighted six factors, drawing on published 2021 data from Car and Driver, MotorTrend, Edmunds, Kelley Blue Book, U.S. News, the IIHS, and the EPA:

• Reliability and ownership cost — 25%: resale, warranty coverage, and brand dependability records.
• Efficiency and powertrain — 20%: EPA combined MPG, hybrid availability, and how the engine actually drives.
• Safety — 20%: IIHS Top Safety Pick / Pick+ status, NHTSA scores, and standard driver-assist tech.
• Comfort and interior — 15%: seat support, ride quality, cabin materials, and trunk space.
• Tech and value — 10%: infotainment, smartphone integration, and standard feature content.
• Price-to-performance — 10%: what each dollar of MSRP returns in real-world capability.

No vehicle here was scored on a single number; the ranking reflects how the whole package holds up over years of ownership, not just one impressive spec.

1. Honda Accord 🏆 BEST OVERALL

Starting MSRP: $24,790 | Best for: Buyers who want one sedan that does everything well

The 2021 Accord LX runs a turbocharged 1.5-liter four-cylinder making 192 hp, with a stronger 252-hp turbo 2.0-liter and a 212-hp hybrid available higher up the range. EPA figures reach 30/38/33 mpg on the 1.5-liter and an excellent 48 mpg combined on most hybrid trims, all front-wheel drive.

The Accord carries the roomiest trunk in the class at 16.7 cubic feet, an IIHS Top Safety Pick+ rating, and Honda Sensing driver aids standard. Its 3-year/36,000-mile bumper-to-bumper and 5-year/60,000-mile powertrain warranty is average, but Honda's reliability reputation is anything but.

Pros:

• Largest trunk and a notably spacious back seat
• Sharpest handling of any non-sport mainstream sedan here
• Strong hybrid option at 48 mpg combined
• Top Safety Pick+ with standard active safety tech

Cons:

• No all-wheel-drive option, unlike several rivals

Verdict: The most complete mid-size sedan of 2021 — fun, frugal, roomy, and safe.

2. Toyota Camry

Starting MSRP: $24,970 | Best for: Buyers who want the lowest long-term ownership cost

The 2021 Camry LE uses a 203-hp 2.5-liter four-cylinder, with an available 301-hp V6 and a class-leading Camry Hybrid from $28,265. EPA ratings run 28/39/32 mpg on the base four and a remarkable 51/53/52 mpg on the Hybrid LE; uniquely in this class, the gas Camry offers available all-wheel drive.

The trunk holds 15.1 cubic feet, and the Camry earned an IIHS Top Safety Pick+ with Toyota Safety Sense standard. Toyota's resale value and dependability records are the strongest in the segment.

Pros:

• Best-in-class hybrid fuel economy at 52 mpg combined
• Available AWD plus an optional 301-hp V6
• Outstanding resale value and reliability
• Top Safety Pick+ with standard driver aids

Cons:

• Base infotainment feels plain next to Hyundai and Kia
• Firmer ride than the comfort-focused competition

Verdict: The smartest choice if you plan to keep the car a decade.

3. Kia K5 💎 BEST VALUE

Starting MSRP: $23,490 | Best for: Bargain hunters who still want style and safety

All-new for 2021 as the Optima's replacement, the K5 LX runs a 180-hp turbocharged 1.6-liter four, with a hot 290-hp 2.5-liter turbo GT on top. EPA ratings reach 29/38 on the LX, and all-wheel drive is available on every trim except the base LX — a rarity at this price.

The K5 earned an IIHS Top Safety Pick+ (units built after November 2020) and brings Kia's class-best 5-year/60,000-mile basic and 10-year/100,000-mile powertrain warranty. Bold styling and a low entry price make it the value leader.

Pros:

• Lowest starting MSRP of any sedan here
• Available AWD across most of the lineup
• 10-year/100,000-mile powertrain warranty
• Top Safety Pick+ and striking exterior design

Cons:

• No hybrid option for 2021
• GT's 290 hp can overwhelm the front tires

Verdict: The most car for the money in 2021, full stop.

4. Hyundai Sonata

Starting MSRP: $23,600 | Best for: Tech-focused buyers who want a long warranty

The redesigned 2021 Sonata offers a 191-hp 2.5-liter four, an available 180-hp turbo 1.6, a 290-hp turbo 2.5 in the N Line, and a hybrid. EPA figures hit 28/38/32 mpg on the base engine and a class-topping 50/54/52 mpg on the Sonata Hybrid Blue. The trunk is generous at 16 cubic feet, and Hyundai's 5-year/60,000-mile and 10-year/100,000-mile warranties match Kia's.

It earned an IIHS Top Safety Pick — one rung below Pick+ because the base headlights rated Marginal.

Pros:

• Class-leading 52-mpg hybrid efficiency
• Long 10-year powertrain warranty
• Genuinely upscale, tech-forward cabin
• Roomy 16-cubic-foot trunk

Cons:

• Base headlights kept it from Top Safety Pick+
• Polarizing exterior styling for some buyers

Verdict: A high-value, high-tech alternative with a standout hybrid.

5. Nissan Altima

Starting MSRP: $24,300 | Best for: Buyers who want available AWD on a budget

The 2021 Altima S starts with a 188-hp 2.5-liter four that offers available all-wheel drive — uncommon in this class — while the SR adds a 248-hp variable-compression VC-Turbo 2.0-liter (FWD only). EPA ratings reach 28/39 mpg on FWD models and 26/36 mpg with AWD.

The Altima earned an IIHS Top Safety Pick+ and comes with Nissan Safety Shield 360 on most trims. Comfortable Zero Gravity seats make it a relaxed highway companion.

Pros:

• Available all-wheel drive at a moderate price
• Comfortable, fatigue-reducing front seats
• Top Safety Pick+ rating
• Strong real-world highway efficiency

Cons:

• CVT can drone under hard acceleration
• VC-Turbo engine can't be paired with AWD

Verdict: The value play for shoppers who specifically need all-wheel grip.

6. Subaru Legacy

Starting MSRP: $22,995 | Best for: All-weather drivers who want standard AWD

The 2021 Legacy is the only sedan here with standard all-wheel drive on every trim. The base 182-hp 2.5-liter flat-four is joined by a 260-hp turbocharged 2.4-liter in the XT models. EPA ratings reach 27/35 mpg on the base engine and 24/32 mpg on the turbo, with 15.1 cubic feet of trunk space.

The Legacy earned an IIHS Top Safety Pick+ and bundles Subaru's EyeSight driver-assist suite as standard. A large 11.6-inch portrait touchscreen anchors the cabin.

Pros:

• Standard all-wheel drive on every model
• Top Safety Pick+ with standard EyeSight
• Available 260-hp turbo for confident passing
• Lowest base price in the group

Cons:

• Base 182-hp engine feels merely adequate
• CVT-only; no traditional automatic

Verdict: The default pick if all-weather traction is non-negotiable.

7. Toyota Camry Hybrid

Starting MSRP: $28,265 | Best for: Commuters chasing maximum MPG without a plug

The Camry Hybrid pairs a 2.5-liter four with electric assist for 208 total system horsepower and delivers a segment-best 51/53/52 mpg in LE trim — figures that rival some compact hybrids. It keeps the standard Camry's 15.1-cubic-foot trunk, front-wheel drive, and IIHS Top Safety Pick+ rating, with Toyota Safety Sense standard.

Beyond the fuel savings, you inherit Toyota's bulletproof hybrid reliability, proven over more than two decades of Prius engineering.

Pros:

• 52 mpg combined — best in the class
• Proven, durable Toyota hybrid system
• Top Safety Pick+ and strong resale
• No range anxiety and no plug required

Cons:

• Higher entry price than the gas Camry
• Less rear cargo flexibility than the Accord

Verdict: The efficiency champion for high-mileage drivers.

8. Honda Accord Hybrid

Starting MSRP: $26,570 | Best for: Buyers who want the Accord's polish plus 48 mpg

The Accord Hybrid blends a 2.0-liter four with two electric motors for 212 total system horsepower, returning 48/48/48 mpg on most trims (44/41/43 on the Touring). It keeps the standard Accord's 16.7-cubic-foot trunk, sharp handling, and IIHS Top Safety Pick+ rating, plus Honda Sensing standard.

You get nearly all of the gas Accord's driving appeal with a roughly 45% bump in efficiency — and a quieter, smoother low-speed demeanor.

Pros:

• 48 mpg combined with full-size practicality
• Retains the class-leading 16.7-cubic-foot trunk
• Engaging to drive for a hybrid
• Top Safety Pick+ rating

Cons:

• Slightly higher price than the gas Accord
• Trails the Camry Hybrid on outright MPG

Verdict: The driver's hybrid — efficiency without sacrificing fun.

9. Mazda6

Starting MSRP: $24,475 | Best for: Drivers who prize premium feel and handling

The 2021 Mazda6 leans on driving feel: a 187-hp 2.5-liter four in lower trims and a 227-hp turbocharged 2.5-liter (310 lb-ft) up top, both front-wheel drive. EPA ratings run 26/35 mpg on the base engine and 23/31 mpg on the turbo. The trunk is the smallest here at 14.7 cubic feet, but the cabin punches above its price in materials, and the Mazda6 earned an IIHS Top Safety Pick+.

It was in its final years on the U.S. Market, lending the design a mature, settled character.

Pros:

• Upscale interior that feels a class above
• Composed, athletic handling
• Top Safety Pick+ rating
• Available 227-hp turbo with strong torque

Cons:

• Smallest trunk and tightest rear seat in the group
• Dated infotainment and no hybrid option

Verdict: The enthusiast's and aesthete's choice, with practicality trade-offs.

10. Volkswagen Passat

Starting MSRP: $23,995 | Best for: Buyers who want a roomy cabin and a big trunk on a budget

The 2021 Passat is the simplest entry here: every trim uses a 174-hp turbocharged 2.0-liter four with a six-speed automatic, front-wheel drive only. EPA ratings land at 24/36 mpg, the lowest combined figures in this group, but the Passat counters with a spacious 15.9-cubic-foot trunk and one of the largest back seats in the class.

It's a comfortable, quiet highway cruiser, though it lacks the safety hardware and efficiency of newer rivals and was in its final stretch before discontinuation.

Pros:

• Generous rear-seat and trunk space
• Quiet, settled highway ride
• Low entry price for the room offered
• Simple, durable single-engine lineup

Cons:

• Lowest horsepower and MPG in the group
• No hybrid, no AWD, and aging tech

Verdict: A roomy budget cruiser, but outclassed by fresher competition.

Buyer Decision Tree — Which One's Right for You?

What to Look For When Buying a Mid-Size Sedan

• Total cost of ownership, not sticker price: factor resale value, warranty length, and expected repair costs. A Camry that holds value can be cheaper over five years than a rival with a lower MSRP.
• Real EPA combined MPG: the combined figure predicts your fuel bill better than the headline highway number.
• Drivetrain match to your climate: standard or available AWD (Legacy, Camry, Altima) earns its keep in snow; in mild regions it mostly adds cost and slightly reduces MPG.
• Trunk and rear-seat room: the Accord's 16.7 and Sonata's 16.0 cubic feet beat the Mazda6's 14.7 — a real difference for families.
• Safety hardware: prioritize an IIHS Top Safety Pick+ with good-rated headlights; the Sonata's Marginal base headlights are a concrete example of why this matters.
• Warranty coverage: Hyundai and Kia's 10-year/100,000-mile powertrain coverage is a tangible long-term hedge.

One thing that matters less than marketing implies: peak horsepower. A 250-plus-hp turbo trim looks exciting on paper, but for the daily commuting that defines most sedan ownership, the base engines here are entirely adequate, and the higher-output versions usually cost more to buy, insure, and fuel without changing how good the car is to live with.
