AT A time when circumstances have required a break in the usual fast pace, the Alfa Romeo Giulia and Stelvio Quadrifoglio, with their 510hp 2.9-litre V6 Bi-turbo engine, are not slowing down, augmenting their supercar-level performance with a wide range of design, technology, and safety upgrades.

The new 2020 Giulia and Stelvio Quadrifoglio are a showcase for Alfa Romeo performance and unmistakably Italian style. The overhaul of the line-up is completed by this concentration of sophisticated technical and performance solutions, in vehicles that embody the most refined expression of functional Italian design, all in inimitable Alfa Romeo style.

Their class-leading performance is guaranteed by the powerful, aluminum, 2.9-litre V6 Bi-turbo engine capable of unleashing 510hp with delivery to the wheels the responsibility of the Alfa Active Torque Vectoring system, assisted in the Stelvio Quadrifoglio by the innovative Q4 all-wheel-drive system.

The eight-speed automatic transmission is calibrated to optimise fluidity and comfort so the vehicles can easily be driven on all terrains.

Only in RACE mode do the cars express their full potential with lightning-fast gear changes in only 150 milliseconds, but each Quadrifoglio is fitted with a range of systems designed to enhance the pleasure of driving, offering motorists the most authentic, engaging experience behind the wheel.

The soundtrack accompanying the Quadrifoglio driving experience is provided by a dual mode quad exhaust system. Customers can opt to fit the 2020 Giulia and Stelvio Quadrifoglio with a new Akrapovič exhaust, another dual mode system, in titanium with carbon fibre tailpipes, featuring an even more sophisticated sound.

On the outside, the new Giulia and Stelvio Quadrifoglio adds new LED rear light clusters with dark lenses and a new glossy black finish adorns the front trilobe and rear badges. The Stelvio also features new 21-inch alloys wheels, seen for the first time on a Quadrifoglio.

Inside, the centre console has been adapted to offer greater tactile and visual impact, while also providing more storage space, a new leather trimmed steering wheel and gear stick are standard and customers can now choose to option red or green seat belts over the classic black version. New perforated upholstery will also be available on the Quadrifoglio models, fitted with leather and Alcantara sports seats as standard and available with optional carbon shell Sparco seats.

The on-board technology has also been upgraded to include the all-new infotainment system with 8.8-inch central touchscreen display, featuring connected services and a new interface design.

The new 2020 Alfa Romeo Giulia Quadrifoglio and Stelvio Quadrifoglio will go on sale in the summer with prices and full UK specification to be confirmed at a later date.
