On the EPA test cycle the Regal Sportback gets better fuel mileage than the MKZ:

Regardless of its engine, the Regal Sportback’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) Lincoln only offers an automatic engine start/stop system on the MKZ Hybrid.

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 MKZ with the 3.0 turbo V6 engine requires premium, which can cost 20 to 55 cents more per gallon.

The Regal Sportback has 2.3 gallons more fuel capacity than the MKZ Hybrid’s standard fuel tank (16.3 vs. 14 gallons), for longer range between fill-ups.


A nine-speed automatic is standard on the Buick Regal Sportback, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the MKZ.

Brakes and Stopping

For better stopping power the Regal Sportback’s front brake rotors are larger than those on the MKZ:

Passenger Space

Because it has more passenger and cargo room, the EPA rates the Regal Sportback a Large car, while the MKZ is rated a Mid-size.

The Regal Sportback has .9 inches more front headroom, .1 inches more front hip room, .8 inches more rear headroom, .3 inches more rear hip room and .1 inches more rear shoulder room than the MKZ.


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

The Regal Sportback GS offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The MKZ doesn’t offer a heads-up display.

When the Regal Sportback with available tilt-down mirrors 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 MKZ’s mirrors don’t automatically adjust for backing.

Model Availability

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

Economic Advantages

Insurance will cost less for the Regal Sportback owner. The Complete Car Cost Guide estimates that insurance for the Regal Sportback will cost $150 to $6000 less than the MKZ over a five-year period.

The Regal Sportback will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Regal Sportback will retain 41.25% to 43.07% of its original price after five years, while the MKZ only retains 38.09% to 40.84%.

According to The Car Book by Jack Gillis, the Regal Sportback is less expensive to operate than the MKZ because typical repairs cost much less on the Regal Sportback than the MKZ, including $45 less for fuel injection, $72 less for a fuel pump, $21 less for front struts, $665 less for a timing belt/chain and $365 less for a power steering pump.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Buick Regal Sportback will be $5294 to $13524 less than for the Lincoln MKZ.
