Alfa Romeo 690T engine

The Alfa Romeo 690T is a twin-turbocharged, direct-injected 90 degree V6 petrol engine that Alfa Romeo has produced since 2015 for the Giulia Quadrifoglio and Stelvio Quadrifoglio. It displaces 2.9 litres (2,891 cc) and makes 375 kW (510 PS) at 6,500 rpm, built at the Termoli plant, which produced 39,833 units from 2015 to 2024. Engineer Gianluca Pivetti, who came from Ferrari, led its development as part of the Giorgio platform project, and although often described as a Ferrari F154 with two cylinders removed, it is a separate design. It has three crankpins at 120 degrees with two rods each, uneven firing, and independent banks, each with its own controller and turbocharger, so that one bank can be deactivated for efficiency.
