Consumer Reports

Tires and Wheels

For better traction, the Sportage SX Turbo’s tires are larger than the largest tires available on the Terrain (245/45R19 vs. 235/50R19).

The Sportage LX’s standard tires provide better handling because they have a lower 60 series profile (height to width ratio) that provides a stiffer sidewall than the Terrain’s standard 65 series tires. The Sportage SX Turbo’s tires have a lower 45 series profile than the Terrain’s optional 50 series tires.

Suspension and Handling

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

For better handling and stability, the average track (width between the wheels) on the Sportage is 1.1 inches wider in the front and 1.4 inches wider in the rear than the track on the Terrain.

The Sportage SX Turbo AWD handles at .83 G’s, while the Terrain Denali AWD pulls only .79 G’s of cornering force in a Motor Trend skidpad test.

The Sportage SX Turbo AWD 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 better maneuverability, the Sportage’s turning circle is 2.6 feet tighter than the Terrain w/17” wheels’ (34.8 feet vs. 37.4 feet). The Sportage’s turning circle is 6.8 feet tighter than the Terrain w/19” wheels’ (34.8 feet vs. 41.6 feet).
