Safety

Both the Terrain and the Blazer 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, daytime running lights, rearview cameras, available all wheel drive, blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Terrain the rating of “Top Pick” for 2017, a rating granted to only 157 vehicles tested by the IIHS. The Blazer has not been tested, yet.

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 Terrain’s reliability 11 points higher than the Blazer.

Suspension and Handling

For better maneuverability, the Terrain w/17” wheels’ turning circle is 1.3 feet tighter than the Blazer’s (37.4 feet vs. 38.7 feet).

Chassis

The GMC Terrain may be more efficient, handle and accelerate better because it weighs about 350 to 500 pounds less than the Chevrolet Blazer.

The Terrain is 9.1 inches shorter than the Blazer, making the Terrain easier to handle, maneuver and park in tight spaces.

Passenger Space

The Terrain has .2 inches more front headroom and .1 inches more rear legroom than the Blazer.

For enhanced passenger comfort on long trips the Terrain’s rear seats recline. The Blazer’s rear seats don’t recline.

Ergonomics

The Terrain’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 Blazer does not have an oil pressure gauge.

When the Terrain with available tilt-down mirrors 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 Blazer’s mirrors don’t automatically adjust for backing.

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