For better traction and acceleration, the Quattroporte has larger standard rear tires than the CT6 (275/40R19 vs. 245/45R19). The Quattroporte’s optional rear tires are larger than the largest rear tires available on the CT6 (285/35R20 vs. 245/45R19).

The Quattroporte’s standard 275/40R19 rear tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the CT6’s standard 45 series tires. The Quattroporte’s optional 245/35R21 front and 285/30R21 rear tires have a lower 35 series front and 30 series rear profile than the CT6 Premium Luxury/Platinum’s 40 series tires.

For better ride, handling and brake cooling the Quattroporte offers optional 21-inch wheels. The CT6’s largest wheels are only 20-inches.

Heated windshield washer nozzles are standard on the Quattroporte to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The CT6 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 Quattroporte has standard headlight washers to keep headlight output high. The CT6 doesn’t offer headlight washers.

The CT6 Premium Luxury/Platinum’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The Quattroporte’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

The Quattroporte has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel is only available on the CT6 Premium Luxury/Platinum.

The Quattroporte offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The CT6 doesn’t offer a house-current electrical outlet.
