For enhanced safety, the front seat shoulder belts of the Chevrolet Tahoe are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW X7 doesn’t offer height-adjustable front 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 Tahoe are reminded to check the back seat if they opened the rear door before starting out. The X7 doesn’t offer a back seat reminder.

The Tahoe 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 X7 doesn’t offer front seat center airbags.

Both the Tahoe and the X7 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available all-wheel drive, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Chevrolet’s powertrain warranty covers the Tahoe 1 year and 10,000 miles longer than BMW covers the X7. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the X7 ends after only 4 years or 50,000 miles.

There are over 8 times as many Chevrolet dealers as there are BMW dealers, which makes it much easier should you ever need service under the Tahoe’s warranty.

The Chevrolet Tahoe’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The BMW X7 only has 5 wheel lugs per wheel.

The Tahoe 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 X7 doesn’t offer vehicle monitored tire inflation.

The Tahoe has a standard full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the X7; it requires you to depend on a temporary spare or run-flat tires, either of which has mileage and speed limitations.

The Tahoe’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The X7’s tailgate’s top part raises up, but the bottom part lowers, getting in the way of loading and making an uneven surface for sliding cargo.

The Tahoe’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 X7 does not have a temperature gauge.

To improve rear visibility by keeping the rear window clear, the Tahoe has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the X7 only has an intermittent setting, so in a hard rain visibility isn’t as good.

The Tahoe has a 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The X7 doesn’t offer a house-current electrical outlet.
