Using vehicle speed sensors and seat sensors, smart airbags in the Accord deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The Accord’s side airbags will shut off if a child is leaning against the door. The Regal Sportback’s side airbags don’t have smart features and will always deploy full force.

The Accord’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Regal Sportback doesn’t offer a driver alert monitor.

Both the Accord and the Regal Sportback 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 blind spot warning systems, rear parking sensors and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, its standard front crash prevention system, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the Accord the rating of “Top Pick” for 2018, a rating granted to only 85 vehicles tested by the IIHS. The Regal Sportback has not been tested, yet.

To lower fuel costs and make buying fuel easier, the Honda Accord uses regular unleaded gasoline. The Regal Sportback with the 2.0 turbo 4 cyl. engine requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Honda Accord higher (6 to 7 out of 10) than the Buick Regal Sportback (5). This means the Accord produces up to 8 pounds less smog-producing pollutants than the Regal Sportback every 15,000 miles.


The Accord offers a manual transmission for better acceleration, control and fuel economy. The Regal Sportback doesn’t offer a manual transmission.

A 10-speed automatic is standard on the Honda Accord 2.0 turbo 4 cyl., for better acceleration and lower engine speed on the highway. Only a nine-speed automatic is available for the Regal Sportback.

The Accord has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The Regal Sportback doesn’t offer a CVT.

Tires and Wheels

The Accord’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Regal Sportback’s standard 55 series tires.

Suspension and Handling

The Accord’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Regal Sportback doesn’t offer drift compensation steering.

The Accord Sport handles at .90 G’s, while the Regal Sportback GS pulls only .87 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the Accord’s turning circle is .9 feet tighter than the Regal Sportback’s (38.1 feet vs. 39 feet). The Accord Sport Manual/2.0T’s turning circle is 1.6 feet tighter than the Regal Sportback’s (39.4 feet vs. 41 feet).


The Honda Accord may be more efficient, handle and accelerate better because it weighs about 600 to 850 pounds less than the Buick Regal Sportback.

The front grille of the Accord EX 1.5T/EX-L 1.5T uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Regal Sportback doesn’t offer active grille shutters.

As tested by Car and Driver while cruising at 70 MPH, the interior of the Accord Touring is quieter than the Regal Sportback Essence (69 vs. 70 dB).

Passenger Space

The Accord has 7.6 cubic feet more passenger volume than the Regal Sportback (105.6 vs. 98).

The Accord has .7 inches more front headroom, .2 inches more front legroom, .1 inches more front hip room, 1.4 inches more front shoulder room, 3.5 inches more rear legroom, .9 inches more rear hip room and 1.1 inches more rear shoulder room than the Regal Sportback.

Cargo Capacity

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the Accord offers cargo security. The Regal Sportback’s hatchback body style, non-lockable folding seat and non-lockable remote release defeat cargo security.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Accord. The Regal Sportback doesn’t offer locking storage for small valuables.


The Accord 2.0L Turbo offers up to a 1000 lbs. towing capacity. The Regal Sportback has no towing capacity.


If the windows are left open on the Accord the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. The driver of the Regal Sportback can only operate the windows from inside the vehicle, with the ignition on.

The Accord’s standard speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The Regal Sportback’s manually variable intermittent wipers have to be constantly adjusted. The Accord Touring’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield.

While driving with high beams on, sensitive light sensors standard on the Accord detect other vehicles which could be blinded and automatically switch to low beams. The Regal Sportback doesn’t offer automatic dimming high beams.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Accord has standard extendable sun visors. The Regal Sportback doesn’t offer extendable visors.

Both the Accord and the Regal Sportback offer available heated front seats. The Accord Touring also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Regal Sportback.

The Accord 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 costs extra on the Regal Sportback.

Economic Advantages

The Accord will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Accord will retain 43.72% to 52.72% of its original price after five years, while the Regal Sportback only retains 41.25% to 43.07%.

According to The Car Book by Jack Gillis, the Accord is less expensive to operate than the Regal Sportback because it costs $747 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the Accord than the Regal Sportback, including $466 less for a water pump, $655 less for a muffler, $147 less for front brake pads, $98 less for a starter, $16 less for front struts and $91 less for a timing belt/chain.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Honda Accord will be $3269 to $7335 less than for the Buick Regal Sportback.
