The X1’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 Terrain doesn’t offer a driver alert monitor.

Both the X1 and the Terrain have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and available all wheel drive.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the BMW X1 is safer than the GMC Terrain:

The X1’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 Terrain’s standard 65 series tires. The X1’s optional tires have a lower 45 series profile than the Terrain’s optional 50 series tires.

For better ride, handling and brake cooling the X1 has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Terrain.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the X1 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Terrain doesn’t offer run-flat tires.

The X1 has standard front and rear stabilizer bars, which help keep the X1 flat and controlled during cornering. The Terrain’s suspension doesn’t offer a rear stabilizer bar.

The X1 xDrive28i handles at .85 G’s, while the Terrain Denali AWD pulls only .79 G’s of cornering force in a Motor Trend skidpad test.

The X1 xDrive28i executes Motor Trend’s “Figure Eight” maneuver quicker than the Terrain Denali AWD (26.8 seconds @ .65 average G’s vs. 27.5 seconds @ .64 average G’s).

For greater off-road capability the X1 has a greater minimum ground clearance than the Terrain SLE (7.2 vs. 6.9 inches), allowing the X1 to travel over rougher terrain without being stopped or damaged.

The X1 uses gas struts to support the hood for easier service access. The Terrain uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

The X1 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 Terrain doesn’t offer a heads-up display.

The X1’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Terrain’s passenger windows don’t close automatically.

If the windows are left open on the X1 the driver can close them all at the outside door handle. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Terrain can only close the windows from inside the vehicle, with the ignition on.

The X1’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Terrain’s manually variable intermittent wipers have to be constantly adjusted.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The X1’s headlights were rated “Acceptable” by the IIHS, while the Terrain’s headlights are rated “Poor.”

To help drivers avoid possible obstacles, the X1 offers optional cornering lights to illuminate around corners when the turn signals are activated. The Terrain doesn’t offer cornering lights.

The X1 has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning costs extra on the Terrain and isn’t available on the Terrain SL.

The X1’s standard automatic temperature control maintains the temperature you set, automatically controlling fan speed, vents and temperature to maintain a consistent, comfortable environment. The Terrain SL doesn’t offer automatic air conditioning.

The X1’s standard GPS navigation system has a real-time traffic update feature that plots alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The Terrain’s available navigation system doesn’t offer real-time traffic updates.

Insurance will cost less for the X1 owner. The Car Book by Jack Gillis rates the X1 with a number “3” insurance rate while the Terrain is rated higher at a number “10” rate.

According to The Car Book by Jack Gillis, the X1 is less expensive to operate than the Terrain because it costs $500 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost less on the X1 than the Terrain, including $65 less for front brake pads and $112 less for a fuel pump.
