Suspension and Handling

The Giulia Quadrifoglio’s front to rear weight distribution is more even (52.6% to 47.4%) than the AMG E 63’s (55.3% to 44.7%). This gives the Giulia Quadrifoglio more stable handling and braking.

The Alfa Romeo Giulia Quadrifoglio may be more efficient, handle and accelerate better because it weighs about 750 to 1000 pounds less than the Mercedes AMG E 63.

The Giulia Quadrifoglio is 1 foot, 1.8 inches shorter than the AMG E 63 Sedan, making the Giulia Quadrifoglio easier to handle, maneuver and park in tight spaces.

As tested by Car and Driver while under full throttle, the interior of the Giulia Quadrifoglio is quieter than the AMG E 63 S Sedan (80 vs. 84 dB).

Passenger Space

The Giulia Quadrifoglio has 1.2 inches more front headroom and 1 inch more front legroom than the AMG E 63 Sedan.


Heated windshield washer nozzles are standard on the Giulia Quadrifoglio to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The AMG E 63 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 Giulia Quadrifoglio has standard headlight washers to keep headlight output high. The AMG E 63 doesn’t offer headlight washers.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Giulia Quadrifoglio has standard extendable sun visors. The AMG E 63 doesn’t offer extendable visors.
