The Alfa Romeo Giulia Quadrifoglio is new to the latest entry to the high performance sports sedan club, and so far it’s looking pretty good. The Italian hot rod rides on a new rear-wheel drive chassis and is loaded with exotic goodies such as a carbon fibre driveshaft, carbon fibre roof panel and hood, and a paddle-shift 8-speed automatic gearbox. The best bit, however, is undoubtedly the Ferrari-inspired 2.9L twin-turbo V6 engine that produces north of 500 horsepower. That’s more than you get from either the M3 or the C63, but given the reputation of that duo, the Quadrifoglio will certainly need it. Is it all enough to top the German adversaries?
