The Regal Sportback offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Accord doesn’t offer all-wheel drive.

Both the Regal Sportback and the Accord have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems, front and rear parking sensors and rear cross-path warning.


The Regal Sportback comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Accord’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

Buick’s powertrain warranty covers the Regal Sportback 1 year and 10,000 miles longer than Honda covers the Accord. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Accord ends after only 5 years or 60,000 miles.

The Regal Sportback’s corrosion warranty is 1 year longer than the Accord’s (6 vs. 5 years).

Buick pays for the first scheduled maintenance on the Regal Sportback. Buick will pay for the first oil change, lubrication and any other required maintenance in the first year. Honda doesn’t pay scheduled maintenance for the Accord.

There are almost 2 times as many Buick dealers as there are Honda dealers, which makes it much easier should you ever need service under the Regal Sportback’s warranty.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Buick vehicles are more reliable than Honda vehicles. J.D. Power ranks Buick third in reliability, above the industry average. With 24 more problems per 100 vehicles, Honda is ranked 12th.

Fuel Economy and Range

In heavy traffic or at stoplights the Regal Sportback’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. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Accord doesn’t offer an automatic engine start/stop system.

The Regal Sportback has 1.5 gallons more fuel capacity than the Accord (16.3 vs. 14.8 gallons), for longer range between fill-ups.

Tires and Wheels

For better traction, the Regal Sportback’s optional tires are larger than the largest tires available on the Accord (245/45R18 vs. 235/40R19).

Suspension and Handling

The Regal Sportback GS handles at .83 G’s, while the Accord EX pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

The Regal Sportback GS executes Motor Trend’s “Figure Eight” maneuver 1.1 seconds quicker than the Accord EX (26.6 seconds @ .67 average G’s vs. 27.7 seconds @ .61 average G’s).

Cargo Capacity

To allow full utilization of available cargo room, the Regal Sportback’s hatch uses gas strut supported hinges that don’t intrude into the cargo area. The Accord’s useful trunk space is reduced by its intrusive beam hinge.

The Regal Sportback’s available folding rear seats are split to accommodate bulky cargo. The Accord LX’s standard single piece folding rear seat is not as flexible; long cargo and a passenger can’t share the rear seat.

Servicing Ease

The Regal Sportback uses gas struts to support the hood for easier service access. The Accord 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.

J.D. Power and Associates surveys of service recipients show that Buick service is better than Honda. J.D. Power ranks Buick 9th in service department satisfaction (above the industry average). With a 41% lower rating, Honda is ranked 25th.


Unlike the driver-only memory system in the Accord EX-L/Touring, the Regal Sportback offers an optional driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The Regal Sportback’s instruments include an oil pressure gauge and a temperature gauge – which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Accord does not have an oil pressure gauge.

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

The Regal Sportback’s front and rear power windows all lower with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Accord’s rear power window switches have to be held the entire time to open them fully.

To help drivers avoid possible obstacles, the Regal Sportback offers optional cornering lights to illuminate around corners when the turn signals are activated. The Accord doesn’t offer cornering lights.

The Regal Sportback’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Honda only offers heated mirrors on the Accord Sport 2.0T/EX/EX-L/Touring.

The Regal Sportback offers optional automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Accord offers an automatic rear view mirror, but its side mirrors don’t dim.

On extremely cold winter days, the Regal Sportback’s optional (except Base) heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Accord doesn’t offer a heated steering wheel.

Both the Regal Sportback and the Accord offer rear vents. For greater rear passenger comfort, the Regal Sportback has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Accord doesn’t offer rear air conditioning vents, only heat vents.

Model Availability

The Buick Regal comes in four door hatchback and station wagon bodystyles; the Honda Accord isn’t available as a station wagon.

Economic Advantages

According to The Car Book by Jack Gillis, the Regal Sportback is less expensive to operate than the Accord because typical repairs cost less on the Regal Sportback than the Accord, including $143 less for fuel injection, $168 less for a fuel pump and $30 less for a power steering pump.
