Value & Performance
The Giulia Quadrifoglio is priced nearly a thousand dollars less than the AMG C 63 S, while both vehicles are priced above BMW’s less costly M3. Although the BMW may hold an advantage in starting price, it also lags behind the Alfa Romeo and Mercedes-Benz in terms of performance. When looking at performance, Alfa Romeo’s Giulia Quadrifoglio takes a decisive lead in this comparison. Simply put, neither competitor can match the Giulia Quadrifoglio’s top speed or horsepower numbers.
Additionally, the Giulia Quadrifoglio has an advanced 8-speed transmission and superior stopping power from standard Brembo brakes — both of which are key advantages on the track. Whether on a street or a front straightaway at the track, those searching for the ultimate in performance thrills should look no further than Alfa Romeo.
Technology and Interior Features
Turning our attention towards standard equipment, the Alfa Romeo Giulia Quadrifoglio continues to excel. Perfect for those chilly mornings, Alfa Romeo drivers will enjoy a standard heated steering wheel — a feature that’s unavailable at Mercedes-Benz and a costly option at BMW. Only BMW can match the Giulia Quadrifoglio for the number of driver’s seat adjustments and voice-activated navigation system, while Mercedes-Benz trails behind in those categories.
Standard front-and-rear parking sensors take the guesswork out of maneuvering the Giulia Quadrifoglio into a tight space. Mercedes-Benz and BMW owners will have to pay extra for this convenience. Finally, all front-seat occupants will find themselves more comfortable in the Giulia Quadrifoglio which offers the greatest front legroom of this bunch.
Winner – Giulia Quadrifoglio
The clear winner in this face-off appears to be Alfa Romeo’s Giulia Quadrifoglio. The Mercedes-Benz AMG C 63 S and BMW M3 simply cannot measure up to the impressive performance and outstanding value offered by the Giulia Quadrifoglio.
