The 2026 Alfa Romeo Giulia Quadrifoglio has not been significantly changed from its predecessor in ways that the specification sheet reveals. The 2.9-liter twin-turbocharged V6, producing 505 horsepower, is carried forward. The carbon fiber driveshaft, the aluminum-intensive structure, and the rear-wheel-drive layout remain. The suspension — double wishbones at the front, multilink at the rear — is calibrated to deliver the steering feel and handling balance that made the previous generation the benchmark for driver engagement in the sports sedan segment.

Autodelta, Alfa Romeo’s racing arm, produced the Giulia Sprint GTA by taking the standard Sprint GT coupe and replacing most of its steel body panels with aluminum. The result — GTA stands for Gran Turismo Alleggerita, lightened — weighed approximately 745 kilograms, which is roughly half the weight of a modern compact car and 200 kilograms less than the standard Sprint GT it was derived from. Into this lightweight package went a 1,570cc twin-cam four-cylinder that produced 115 horsepower in road tune and upward of 170 in full race preparation, driving through a five-speed gearbox to a limited-slip differential.
