                        For enhanced safety, the Buick Enclave’s middle seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Lincoln MKX doesn’t offer comfort guides on its middle seat belts.

                        In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Enclave are reminded to check the back seat if they opened the rear door before starting out. The Lincoln MKX doesn’t offer a back seat reminder.

                        The Enclave has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Lincoln MKX doesn’t offer front seat center airbags.

                        Both the Enclave and the Lincoln MKX have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.


                        The Enclave’s corrosion warranty is 1 year longer than the Lincoln MKX’s (6 vs. 5 years).

                        There are over 2 times as many Buick dealers as there are Lincoln dealers, which makes it much easier should you ever need service under the Enclave’s warranty.


                        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 Enclave’s reliability 11 points higher than the Lincoln MKX.

                        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 Lincoln vehicles. J.D. Power ranks Buick third in reliability, above the industry average. With 17 more problems per 100 vehicles, Lincoln is ranked 10th.

                        From surveys of all its subscribers, Consumer Reports’ April 2018 Auto Issue reports that Buick vehicles are more reliable than Lincoln vehicles. Consumer Reports ranks Buick 14 places higher in reliability than Lincoln.


                        The Enclave’s 3.6 DOHC V6 produces 7 more horsepower (310 vs. 303) than the Lincoln MKX’s standard 3.7 DOHC V6.

                        Fuel Economy and Range

                        On the EPA test cycle the Enclave gets better fuel mileage than the Lincoln MKX:




                        Lincoln MKX



                        3.6 V6/9-spd. Auto

                        18 city/26 hwy

                        17 city/25 hwy

                        3.7 V6/Auto


                        3.6 V6/9-spd. Auto

                        17 city/25 hwy

                        16 city/23 hwy

                        3.7 V6/Auto

                        In heavy traffic or at stoplights the Enclave’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 Lincoln MKX doesn’t offer an automatic engine start/stop system.

                        To lower fuel costs and make buying fuel easier, the Buick Enclave uses regular unleaded gasoline. The Lincoln MKX with the 2.7 turbo V6 engine requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

                        The Enclave FWD’s standard fuel tank has 1.4 gallons more fuel capacity than the Lincoln MKX (19.4 vs. 18 gallons), for longer range between fill-ups. The Enclave AWD’s standard fuel tank has 3.7 gallons more fuel capacity than the Lincoln MKX (21.7 vs. 18 gallons).

                        Environmental Friendliness

                        In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Buick Enclave higher (6 out of 10) than the Lincoln MKX (3 to 5). This means the Enclave produces up to 23.4 pounds less smog-producing pollutants than the Lincoln MKX every 15,000 miles.


                        A nine-speed automatic is standard on the Buick Enclave, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the Lincoln MKX.

                        Brakes and Stopping

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

                        Tires and Wheels

                        For better traction, the Enclave has larger tires than the Lincoln MKX (255/65R18 vs. 245/60R18).

                        The Buick Enclave’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Lincoln MKX only has 5 wheel lugs per wheel.

                        The Enclave has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Lincoln MKX doesn’t offer vehicle monitored tire inflation.

                        Suspension and Handling

                        For a smoother ride and more stable handling, the Enclave’s wheelbase is 8.7 inches longer than on the Lincoln MKX (120.9 inches vs. 112.2 inches).

                        For better handling and stability, the track (width between the wheels) on the Enclave is 2.5 inches wider in the front and 2.3 inches wider in the rear than on the Lincoln MKX.

                        Passenger Space

                        The Enclave has standard seating for 7 passengers; the Lincoln MKX can only carry 5.

                        The Enclave has 1.1 inches more front headroom, 2.7 inches more front hip room, 3.5 inches more front shoulder room, .7 inches more rear headroom, 2.1 inches more rear hip room and 2.7 inches more rear shoulder room than the Lincoln MKX.

                        Cargo Capacity

                        The Enclave’s cargo area provides more volume than the Lincoln MKX.

                        58 cubic feet

                        37.2 cubic feet

                        Second Seat Folded

                        97.6 cubic feet

                        68.8 cubic feet

                        The Enclave’s cargo area is larger than the Lincoln MKX’s in every dimension:




                        Length to seat (3rd/2nd/1st)



                        Max Width



                        Min Width







                        Maximum trailer towing in the Lincoln MKX is limited to 3500 pounds. The Enclave offers up to a 5000 lbs. towing capacity.


                        When the Enclave Premium/Avenir 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 Lincoln MKX’s mirrors don’t automatically adjust for backing.

                        Economic Advantages

                        According to The Car Book by Jack Gillis, the Enclave is less expensive to operate than the Lincoln MKX because typical repairs cost much less on the Enclave than the Lincoln MKX, including $65 less for a muffler, $94 less for front struts and $208 less for a timing belt/chain.


                        The Buick Enclave outsold the Lincoln MKX by 57% during 2017.
