Throttle House gives the 2020 Alfa Romeo Giulia Quadrifoglio a positive review with a score of 68/100, praising it as one of the best sports sedans ever that drives like a mini Ferrari. The car excels in performance with its Ferrari-derived 505-hp turbocharged V6 delivering "rampantly, violently fast" acceleration and precise steering, while its stunning design and exceptional value—priced at just $49,000 CAD with adaptive dampers and a captivating exhaust note—make it highly compelling. However, potential buyers should be aware of significant reliability quirks like battery voltage issues causing limp mode and wastegate codes, plus prohibitively expensive parts and maintenance, including $25,000 carbon ceramic brake replacements. The Quadrifoglio is ideal for enthusiasts who prioritize thrilling performance and striking design over long-term ownership costs and perfect reliability.
