The engine in the Stelvio has a single overhead cam for simplicity. The engines in the RX Series have dual overhead cams, which add to the number of moving parts and the complexity of the cylinder heads.

The battery on the Stelvio is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the Stelvio’s battery 20 to 30 degrees cooler, its life is increased by years. The RX Series’ battery is in the hot engine compartment.

For better traction, the Stelvio’s optional tires are larger than the largest tires available on the RX Series (255/45R20 vs. 235/65R18).

The Stelvio’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 RX Series’ standard 65 series tires. The Stelvio’s optional tires have a lower 45 series profile than the RX Series’ optional 55 series tires.

For a smoother ride and more stable handling, the Stelvio’s wheelbase is 1.1 inches longer than on the RX Series (110.9 inches vs. 109.8 inches).

The Stelvio’s front to rear weight distribution is more even (50% to 50%) than the RX Series’ (57% to 43%). This gives the Stelvio more stable handling and braking.

The Stelvio Ti AWD handles at .82 G’s, while the RX 450h pulls only .78 G’s of cornering force in a Motor Trend skidpad test.

The Stelvio Ti AWD executes Motor Trend’s “Figure Eight” maneuver quicker than the RX 450h (26.9 seconds @ .67 average G’s vs. 27.5 seconds @ .65 average G’s).

The Alfa Romeo Stelvio may be more efficient, handle and accelerate better because it weighs about 300 to 750 pounds less than the Lexus RX Series.

The Stelvio is 7.9 inches shorter than the RX Series, making the Stelvio easier to handle, maneuver and park in tight spaces.

The engine in the Stelvio is mounted longitudinally (North-South), instead of sideways, as in the RX Series. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

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

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Alfa Romeo Stelvio offers an optional wireless phone charging system (Qi) in the center console. The RX Series doesn’t offer wireless personal charging.
