The Quattroporte has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The AMG CLS doesn’t offer a cap-less fueling system.

For better ride, handling and brake cooling the Quattroporte offers optional 21-inch wheels. The AMG CLS’ largest wheels are only 20-inches in the front and 19-inches in the rear.

The Quattroporte has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the AMG CLS; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some tire options on the AMG CLS don’t have a run-flat feature, either.

The Quattroporte has standard front and rear gas-charged shocks for better control over choppy roads. The AMG CLS’ suspension doesn’t offer gas-charged shocks.

For a smoother ride and more stable handling, the Quattroporte’s wheelbase is 9.1 inches longer than on the AMG CLS (124.8 inches vs. 115.7 inches).

The Maserati Quattroporte may be more efficient, handle and accelerate better because it weighs about 200 to 350 pounds less than the Mercedes AMG CLS.

The front grille of the Quattroporte uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The AMG CLS doesn’t offer active grille shutters.

The Quattroporte’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 AMG CLS does not have an oil pressure gauge.

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 AMG CLS doesn’t offer headlight washers.

A power rear sunshade and rear side window sunshades are standard in the Quattroporte to help block heat and glare for the rear passengers. The AMG CLS doesn’t offer rear side window sunshades.

Optional air conditioned front and rear seats keep the Quattroporte’s passengers comfortable and take the sting out of hot leather in summer. The AMG CLS doesn’t offer air-conditioned seats in the rear.

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 costs extra on the AMG CLS.
