Alfa Romeo Giulia Quadrifoglio

A four-door that argues back, and wins the argument.

The Alfa Romeo Giulia Quadrifoglio is the performance flagship of Alfa Romeo's modern sedan lineup, pairing a twin-turbo V6 with a rear-wheel-drive layout and a body that screams Italian design heritage. In the Forza universe, it occupies a special niche: a sharp, communicative, almost argumentative sedan that rewards the driver who respects its temperament rather than one who simply floors it.

Lore & Background

Alfa Romeo has spent a century building cars that feel less like machines and more like moods. The Giulia Quadrifoglio continues that tradition in the Forza world, where it sits among the game's most characterful sedans. Its front end, with the iconic trilobe grille and sculpted fenders, reads as pure Italian aggression, while the cabin—though you rarely see it in gameplay—carries the same handcrafted intent. In the open-road chaos of Forza Horizon, it's the car you pick when you want to feel the tarmac through your fingertips rather than just watch a speedometer climb.

Reader's Guide

Alfa Romeo Giulia Quadrifoglio, 2017, Class S2 sedan.

Stock, the Giulia Quadrifoglio is a rear-wheel-drive sedan with a 2.9-litre twin-turbo V6 producing roughly 505 horsepower. It is light for a four-door, nimble, and its handling is rated high—sharp steering, quick rotation, and a rear end that is eager if you let it be. Top speed is competitive but not supercar territory; its real strength is mid-corner agility and throttle response.

Tuning levers in Forza Horizon are generous. You can swap the exhaust for a freer-flowing unit, add a more aggressive turbo or intercooler, and push the V6 well past its stock output. Suspension can be lowered and stiffened to reduce body roll, and you can widen the rear track and fit a stickier tyre compound for more grip. Brakes can be upgraded to handle the extra stopping force, and a rear wing plus front splitter add downforce for high-speed stability.

The trade-offs are real. A heavier engine swap or excessive aero drag will blunt the car's lightness and quickness. Over-stiffening the suspension makes it twitchy and unforgiving on rough surfaces. Widening the rear without matching the front can make the car snap rather than slide. The Giulia wants balance; push one axis too far and it stops feeling like an Alfa and starts feeling like a go-kart with a V6 bolted in.

Build philosophy: treat the Giulia Quadrifoglio like a dance partner, not a tractor—add just enough power and grip to make it sing, and let the steering do the talking.
