Safety Comparison

The X5 has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Tahoe doesn’t offer a whiplash protection system.

A passive infrared night vision system optional on the X5 helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The Tahoe doesn’t offer a night vision system.

The X5 offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The Tahoe only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

The X5’s optional driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Tahoe doesn’t offer a driver alert monitor.

For better protection of the passenger compartment, the X5 uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The Tahoe uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the X5 and the Tahoe have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rear parking sensors, available all wheel drive, crash mitigating brakes, lane departure warning systems and blind spot warning systems.

Warranty Comparison

The X5 comes with a full 4 year/50,000 mile basic warranty, which covers the entire truck and includes 24 hour roadside assistance. The Tahoe’s 3 year/36,000 mile basic warranty expires 1 year and 14,000 miles sooner.

The X5’s corrosion warranty is 6 years and unlimited miles longer than the Tahoe’s (12/unlimited vs. 6/100,000).

BMW pays for scheduled maintenance on the X5 for 1 year and 12000 miles longer than Chevrolet pays for maintenance for the Tahoe (3/36,000 vs. 2/24,000).

Reliability Comparison

For smoother operation, better efficiency and fewer moving parts, the engines in the X5 have an overhead cam design, rather than the old pushrod design of the engine in the Tahoe.

To reliably power the ignition and other systems and to recharge the battery, the X5 has a standard 210-amp alternator. The Tahoe’s 150-amp alternator isn’t as powerful.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without their vehicle while it’s being repaired. Consumer Reports predicts that the X5’s reliability will be 76% better than the Tahoe.

J.D. Power and Associates’ 2016 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Chevrolet vehicles. J.D. Power ranks BMW fifth in initial quality, above the industry average. With 1 more problems per 100 vehicles, Chevrolet is ranked 6th.

Engine Comparison

The X5 xDrive50i’s standard 4.4 turbo V8 produces 90 more horsepower (445 vs. 355) and 97 lbs.-ft. more torque (480 vs. 383) than the Tahoe’s 5.3 V8.

The X5’s 3.0 turbo diesel produces 30 lbs.-ft. more torque (413 vs. 383) than the Tahoe’s 5.3 V8.

Regenerative brakes improve the X5’s fuel efficiency by converting inertia back into energy instead of wasting it. The Tahoe doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the X5’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 Tahoe doesn’t offer an automatic engine start/stop system.

Brakes and Stopping Comparison

Tires and Wheels Comparison

The X5’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Tahoe LS/LT’s standard 65 series tires. The X5’s optional 275/40R20 front and 315/35R20 rear tires have a lower 40 series front and 35 series rear profile than the Tahoe’s optional 45 series tires.

For better ride, handling and brake cooling the X5 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Tahoe LS/LT.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the X5 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Tahoe doesn’t offer run-flat tires.

Suspension and Handling Comparison

For superior ride and handling, the BMW X5 has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Chevrolet Tahoe has a solid rear axle, with a non-independent rear suspension.

The X5 has standard front and rear stabilizer bars, which help keep the X5 flat and controlled during cornering. The Tahoe’s suspension doesn’t offer a rear stabilizer bar.

The X5 offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Chevrolet doesn’t offer an active suspension on the Tahoe.

The X5 xDrive35i xDrive handles at .79 G’s, while the Tahoe Premier 4x4 pulls only .76 G’s of cornering force in a Car and Driver skidpad test.

The X5 xDrive50i xDrive executes Motor Trend’s “Figure Eight” maneuver 2 seconds quicker than the Tahoe Premier 4x4 (26.3 seconds @ .72 average G’s vs. 28.3 seconds @ .62 average G’s).

For greater off-road capability the X5 has a greater minimum ground clearance than the Tahoe (8.2 vs. 7.9 inches), allowing the X5 to travel over rougher terrain without being stopped or damaged.

Chassis Comparison

The BMW X5 may be more efficient, handle and accelerate better because it weighs about 550 to 750 pounds less than the Chevrolet Tahoe.

The X5 is 10.8 inches shorter than the Tahoe, making the X5 easier to handle, maneuver and park in tight spaces.

Unibody construction makes the X5’s chassis much stiffer, which contributes to better handling, and enables softer springs to be used for a better ride. Unibody construction’s stiffness also contributes to better durability and less body squeaks and rattles. The Tahoe doesn’t use unibody construction, but a body-on-frame design.

As tested by Car and Driver while cruising at 70 MPH, the interior of the X5 xDrive35i xDrive is quieter than the Tahoe Premier 4x4 (64 vs. 66 dB).

Ergonomics Comparison

The X5’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Tahoe’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left down on the X5 the driver can raise them all using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the Tahoe can only operate the windows from inside the vehicle, with the ignition on.

The X5 has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The Tahoe doesn’t offer a locking fuel door.

Heated windshield washer nozzles are standard on the X5 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Tahoe doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The X5 offers available headlight washers to keep headlight output high. The Tahoe doesn’t offer headlight washers.

To help drivers see further while navigating curves, the X5 has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Tahoe doesn’t offer cornering lights.

The X5’s optional Parking Assistant can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Tahoe doesn’t offer an automated parking system.

Economic Advantages Comparison

Insurance will cost less for the X5 owner. The Car Book by Jack Gillis rates the X5 with a number “3” insurance rate while the Tahoe is rated higher at a number “10” rate.

According to The Car Book by Jack Gillis, the X5 is less expensive to operate than the Tahoe because it costs $225 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the X5 than the Tahoe, including $402 less for a fuel pump.
