What Car? says...
Few car manufacturers possess a name and performance motif as evocative as Alfa’s four-leaf clover. It’s affixed to only the firm’s most potent models, and the Alfa Romeo Giulia Quadrifoglio (Quadrifoglio being the Italian for four-leaf clover, in case you were wondering) more than proves the value of its historic name.
It’s built on the same lightweight, rear-wheel-drive underpinnings as the regular Giulia executive saloon, but the Quadrifoglio version comes fitted with a staggeringly powerful 503bhp turbocharged 2.9-litre V6 petrol engine. That means it’s good for 0-62mph in just 3.9sec and a downright crazy top speed of 190mph. To put all that power to good use, it gets bespoke suspension and quicker steering, as well as larger brakes to make sure it stops as well as it goes.
