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. Infiniti doesn’t pay scheduled maintenance for the QX50.

There are almost 10 times as many Buick dealers as there are Infiniti dealers, which makes it much easier should you ever need service under the Regal Sportback’s warranty.

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 QX50 doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Buick Regal Sportback uses regular unleaded gasoline (premium recommended with the 2.0 turbo 4 cyl. engine for maximum performance). The QX50 requires premium, which can cost 20 to 55 cents more per gallon.

The Regal Sportback has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The QX50 doesn’t offer a cap-less fueling system.

The Regal Sportback Avenir/GS’ tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the QX50 Essential’s optional 45 series tires.

The Regal Sportback offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The QX50’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the Regal Sportback’s wheelbase is 1.2 inches longer than on the QX50 (111.4 inches vs. 110.2 inches).

Unlike the driver-only memory system optional in the QX50 Essential, 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 QX50 does not have an oil pressure gauge.

The power windows standard on both the Regal Sportback and the QX50 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 QX50 prevents the driver from operating the other windows just as it does the other passengers.

The Regal Sportback’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Infiniti only offers heated mirrors on the QX50 Essential.

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 QX50 offers an automatic rear view mirror, but its side mirrors don’t dim.

Insurance will cost less for the Regal Sportback owner. The Car Book by Jack Gillis rates the Regal Sportback with a number “8” insurance rate while the QX50 is rated higher at a number “10” rate.

According to The Car Book by Jack Gillis, the Regal Sportback is less expensive to operate than the QX50 because typical repairs cost much less on the Regal Sportback than the QX50, including $97 less for a fuel pump, $19 less for front struts, $285 less for a timing belt/chain and $444 less for a power steering pump.
