Warranty

The Sonata Hybrid comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Altima’s 3-year/36,000-mile basic warranty expires 2 years or 24,000 miles sooner.

Hyundai’s powertrain warranty covers the Sonata Hybrid 5 years and 40,000 miles longer than Nissan covers the Altima. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the Altima ends after only 5 years or 60,000 miles.

The Sonata Hybrid’s corrosion warranty is 2 years longer than the Altima’s (7 vs. 5 years).

Hyundai pays for scheduled maintenance on the Sonata Hybrid for 3 years and 36,000 miles. Hyundai will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Nissan doesn’t pay scheduled maintenance for the Altima.

Reliability

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Sonata Hybrid’s reliability 13 points higher than the Altima.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the statistics that show that Hyundai vehicles are more reliable than Nissan vehicles. J.D. Power ranks Hyundai third in reliability, above the industry average. With 57 more problems per 100 vehicles, Nissan is ranked 20th.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Hyundai vehicles are more reliable than Nissan vehicles. Consumer Reports ranks Hyundai 6 places higher in reliability than Nissan.

Engine

The Sonata Hybrid’s 2.0 DOHC 4-cylinder hybrid produces 10 more horsepower (192 vs. 182) and 93 lbs.-ft. more torque (271 vs. 178) than the Altima AWD’s optional 2.5 DOHC 4-cylinder. The Sonata Hybrid’s 2.0 DOHC 4-cylinder hybrid produces 4 more horsepower (192 vs. 188) and 91 lbs.-ft. more torque (271 vs. 180) than the Altima’s standard 2.5 DOHC 4-cylinder.

Fuel Economy and Range

On the EPA test cycle the Sonata Hybrid gets better mileage than the Altima:

			MPG
Sonata Hybrid
	FWD	2.0 4-cyl. Hybrid	44 city/51 hwy
Altima
	FWD	S/SV 2.5 DOHC 4-cyl.	27 city/39 hwy
		SL/SR 2.5 DOHC 4-cyl.	27 city/37 hwy
		2.0 turbo 4-cyl.	25 city/34 hwy
	AWD	2.5 DOHC 4-cyl.	26 city/36 hwy

Regenerative brakes improve the Sonata Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The Altima doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the Sonata Hybrid’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. The Altima doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Hyundai Sonata Hybrid uses regular unleaded gasoline. The Altima SR requires premium for maximum efficiency, which can cost on average about 82.8 cents more per gallon.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Hyundai Sonata Hybrid higher (7 out of 10) than the Nissan Altima (6 to 7). This means the Sonata Hybrid produces up to 1.1 pounds less smog-producing pollutants than the Altima every 15,000 miles.

Brakes and Stopping

For better stopping power the Sonata Hybrid’s brake rotors are larger than those on the Altima:

	Sonata Hybrid	Altima
Front Rotors	12 inches	11.65 inches
Rear Rotors	11.2 inches	11.02 inches

The Sonata Hybrid’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Altima are solid, not vented.

Tires and Wheels

The Sonata Hybrid’s tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Altima S’ standard 60 series tires.

For better ride, handling and brake cooling the Sonata Hybrid has standard 17-inch wheels. Smaller 16-inch wheels are standard on the Altima S.

Suspension and Handling

For better maneuverability, the Sonata Hybrid’s turning circle is .2 feet tighter than the Altima S’ (35.9 feet vs. 36.1 feet). The Sonata Hybrid’s turning circle is 1.5 feet tighter than the Altima SR/SV/SL/Platinum’s (35.9 feet vs. 37.4 feet).

Chassis

The design of the Hyundai Sonata Hybrid amounts to more than styling. The Sonata Hybrid has an aerodynamic coefficient of drag of .24 Cd. That is lower than the Altima (.26) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Sonata Hybrid get better fuel mileage.

Passenger Space

Because it has more passenger and cargo room, the EPA rates the Sonata Hybrid a Large car, while the Altima is rated a Mid-size.

The Sonata Hybrid has 3.8 cubic feet more passenger volume than the Altima (104.4 vs. 100.6).

The Sonata Hybrid has .9 inches more front headroom, 2.3 inches more front legroom and 1.5 inches more rear headroom than the Altima.

Cargo Capacity

To allow full utilization of available cargo room, the Sonata Hybrid’s trunk lid uses concealed beam hinges that don’t intrude into the trunk. Its intrusive beam hinge reduces the Altima’s useful trunk space.

To make loading and unloading groceries and cargo easier when your hands are full, the Sonata Hybrid’s trunk can be opened just by waiting momentarily behind the back bumper, leaving your hands completely free. The Sonata Hybrid Limited also has a standard power trunk, which opens and closes automatically by pressing a button. The Altima doesn’t offer a power or hands-free opening trunk.

Servicing Ease

The Sonata Hybrid uses gas struts to support the hood for easier service access. The Altima uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

Ergonomics

When two different drivers share the Sonata Hybrid Limited, the memory seats and mirrors make it convenient for both. Each setting activates different, customized memories for the driver’s seat position and outside mirror angle. The Altima doesn’t offer a memory system.

The Sonata Hybrid Limited’s standard easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Altima doesn’t offer an easy entry system.

The Sonata Hybrid Limited has a standard heads-up display that projects speed, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Altima doesn’t offer a heads-up display.

The Sonata Hybrid’s power parking brake sets with one touch and releases with one touch or automatically. The Altima’s parking brake has to be released manually.

The power windows standard on both the Sonata Hybrid and the Altima have locks to prevent small children from operating them. When the lock on the Sonata Hybrid is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Altima prevents the driver from operating the other windows just as it does the other passengers.

The Sonata Hybrid’s front power windows open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Altima’s passenger windows don’t open or close automatically.

On a hot day the Sonata Hybrid’s driver can lower all the windows from a distance using the keyless remote. The driver of the Altima can only operate the windows from inside the vehicle, with the ignition on.

The Sonata Hybrid has a standard Proximity Key that allows you to unlock the doors from either front door handle, open the trunk, and start the engine, all without removing the key from the pocket or purse. Only the Altima SR/SV/SL offers an Intelligent Key.

The Sonata Hybrid’s power window and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Altima’s power window (except driver window) switches are unlit, making them difficult to find at night and operate safely.

The Sonata Hybrid Limited’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The Altima’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The Sonata Hybrid’s headlights were rated “Good” by the IIHS, while the Altima’s headlights are rated “Acceptable.”

Manual rear side window sunshades are available in the Sonata Hybrid to help block heat and glare for the rear passengers. The Altima doesn’t offer rear side window sunshades.

The Sonata Hybrid’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Heated mirrors cost extra on the Altima and aren’t offered on the Altima S.

When the Sonata Hybrid Limited is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Altima’s mirrors don’t automatically adjust for backing.

Standard air-conditioned seats in the Sonata Hybrid Limited keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Altima doesn’t offer air-conditioned seats.

The Sonata Hybrid has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning is only available on the Altima SL/SR VC-Turbo.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Hyundai Sonata Hybrid has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the Altima and isn’t available on the Altima S.

The Sonata Hybrid Limited’s Remote Smart Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Smart Parking Assist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The Altima doesn’t offer an automated parking system.

Economic Advantages

Insurance will cost less for the Sonata Hybrid owner. The Complete Car Cost Guide estimates that insurance for the Sonata Hybrid will cost $325 less than the Altima over a five-year period.

The Sonata Hybrid will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Sonata Hybrid will retain 49.24% to 50.94% of its original price after five years, while the Altima only retains 41.69% to 47.34%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Hyundai Sonata Hybrid will be $3226 to $9437 less than for the Nissan Altima.
