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 Suburban 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 Suburban 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 Suburban and the X7 have standard driver and passenger frontal airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems, front parking sensors and rear cross-path warning.
Chevrolet’s powertrain warranty covers the Suburban 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 almost 9 times as many Chevrolet dealers as there are BMW dealers, which makes it much easier should you ever need service under the Suburban’s warranty.
The Suburban has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The X7 doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the truck’s engine.

The Suburban’s standard 5.3 V8 produces 20 more horsepower (355 vs. 335) and 53 lbs.-ft. more torque (383 vs. 330) than the X7 xDrive40i’s standard 3.0 turbo 6 cyl.
An engine control system that can shut down half of the engine’s cylinders helps improve the Suburban’s fuel efficiency. The X7 doesn’t offer a system that can shut down part of the engine.
To lower fuel costs and make buying fuel easier, the Chevrolet Suburban uses regular unleaded gasoline (premium recommended with the 6.2 V8 engine for maximum performance). The X7 requires premium, which can cost 20 to 55 cents more per gallon.
The Suburban has 9.1 gallons more fuel capacity than the X7 (31 vs. 21.9 gallons), for longer range between fill-ups.
A 10-speed automatic is standard on the Chevrolet Suburban EcoTec3 6.2 V8, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the X7.
The Chevrolet Suburban’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 Suburban 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 Suburban 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.
For a smoother ride and more stable handling, the Suburban’s wheelbase is 7.8 inches longer than on the X7 (130 inches vs. 122.2 inches).

The Suburban’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.
To make loading groceries and cargo easier when your hands are full, the Suburban’s available liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The X7 doesn’t offer a hands-free gesture to open its tailgate, forcing you to put cargo down if your hands are full.
