Alfa-Romeo-Giulia-46

Despite the recent announcement of further market launch delays for the new 2017 Alfa Romeo Giulia Quadrifoglio, the Italian car maker has just revealed full specifications for its range-topping variant ahead of its US debut at the LA Auto Show.

Expected to be launched in the States by the second quarter of 2016, Alfa has also set for its Giulia Quadrifoglio an MSRP price tag of USD$70,000 (RM306k). Comparatively, its BMW nemesis, the M3 sedan, is priced from USD$63,200 (RM277k) in the same region.

Based on Alfa’s new rear-wheel drive Giorgio architecture and designed to offer a near-perfect 50/50 weight distribution, the top-shelf Giulia Quadrifoglio is equipped with a Ferrari-derived 3.0 litre biturbo V6 engine. Alfa’s most powerful production car engine ever is capable of 505 hp, with 600 Nm of torque available between 2,500 and 5,000 rpm.

The Quadrifoglio also features cylinder deactivation technology that allows it to run on just three of its six cylinders when full power is not required, thus improving the car’s fuel consumption by up to 15%. The Alfa is also equipped with an engine start-stop (ESS) system that completely cuts off fuel flow and shuts the powertrain down when the car is at a full stop and the brake pedal is depressed.

Sending all power to the rear wheels via a sole six-speed manual transmission option and a carbon-fibre driveshaft, the Quadrifoglio performs a century sprint in 3.9 seconds, with its top speed limited to 307 km/h.

Where handling and performance is concerned, the Italian BMW M3-fighter gets an active damping suspension that can be adjusted by drivers via the Alfa DNA Pro drive mode selector, which also modifies throttle, steering and transmission behaviour to match. Four modes are available from the DNA Pro drive selector, being Dynamic, Natural, Advanced Efficiency and an all-out Race mode.

Just in case you missed it, Alfa has also claimed a Nurburgring lap time of seven minutes and 39 seconds. The four-door Italian sedan proved even quicker than the mighty F82 BMW M4, which managed a 7:52 lap.

Outside, the sculpted lines of the Giulia features the Italian car maker’s “shield” front grille design within the front fascia, forming an integral part of the brand’s signature “Trilobo” motif. Bi-xenon projector headlamps with adaptive front-lighting flank the front grille with integrated LED daytime running lights as standard.

It’s also a good time to bring up the Quadrifoglio’s extensive use of carbon-fibre materials, used to make the active aero front splitter, hood, roof, driveshaft and more.

At the rear, a carbon-fibre boot lid spoiler is included, with narrow LED rear light clusters setting off the aggressive look. Airflow around the rear of the vehicle is managed by an integrated diffuser, further stabilising the Quadrifoglio at high speeds. The quad exhaust tips are linked to a dual-mode exhaust system that can distinctively vary the V6’s exhaust notes.

For wheels, the Quadrifoglio gets a set of staggered-fitting 19-inch alloy wheels, wrapped in Pirelli P Zero Corsa rubbers in sizes of 245/35ZR19 up front and 285/30ZR19 at the rear. Two different wheels are available, being the lightweight forged aluminium “Technico” rollers or the brand’s signature five-hole designs. Both are available in either Bright Silver, or Dark Grey.

The Quadrifoglio comes standard-equipped with a Brembo brake system with vented iron discs and brake calipers. Optionally, more stopping power is available via carbon-ceramic brake rotors. Alfa has also developed an improved braking system for its top-spec Giulia which is said to provide more instantaneous braking response, while also offering variable brake feel that can be tuned by the DNA Pro drive modes.

Inside the Quadrifoglio, an abundant use of leather, Alcantara, carbon-fibre, aluminium and red accent stitching brings together the car’s sporty interior design. Further highlighting the raw dynamic athleticism of the car is a flat-bottomed, multi-function three-spoke steering wheel that is said to be inspired by Formula 1, to the extent of it even featuring a red engine start-stop button.

A full-colour seven-inch driver information display (DID) screen is positioned between two analogue dials, while a further 8.8 inch display screen is positioned centrally on the dashboard, but slightly angled towards the driver. The widescreen display offers real-time vehicle performance data and telemetry, as well as 3D navigation views.

The Alfa Rotary Pad positioned on the centre console offers gesture recognition, allowing drivers to interact with the system’s navigation, for example, with their finger tips. Leather-Alcantara sports seats (pictured here) are available in the Quadrifoglio as standard, but Sparco racing seats are optionally available.

Spicing up the interior, Alfa says that it’s top-spec Giulia will have up to five leather-Alcantara interior combinations to choose from. First, an all-black interior with a choice of black, white and green or red accent stitching. There’s also a two-tone black with red interior and matching red accent stitching.

US customers will also be able to specify their Quadrifoglio with a two-tone black with Ice interior combination and its signature green and white Quadrifoglio accent stitching — a nice throwback to Alfa’s historic four-leaf clover logo.

There are also seven exterior colours for customers to choose from, being Rosso Alfa (Red), Vulcano Black Metallic, Silverstone Grey Metallic, Montecarlo Blue Metallic, Vesuvio Grey Metallic, Trofeo White Tri-Coat, and Rosso Competizione Tri-Coat (Red).

Following the range-topping Giulia Quadrifoglio’s North American and European introductions, the Italian car maker has also confirmed that other Alfa Romeo Giulia variants will make their market debuts. A new 276 hp 2.0 litre turbocharged petrol engine with direct-injection has been poised to power lower-spec Giulia variants.

The new mills will also feature a MultiAir2 system that can simultaneously control both intake valve opening and closing to optimise combustion quality, plus an efficient internal exhaust-gas recirculation (EGR) system which is said to improve fuel economy.

Alfa has also said that the four-pot turbo variants coming in 2016 may be optionally specified with all-wheel drive systems, while a dual-clutch automatic transmission has been tipped to be available alongside the six-speed manual.
