Powered by a new 510bhp, 600Nm bi-turbo V6 petrol engine, with an eight-speed paddle shift automatic transmission as standard, the Alfa Romeo Giulia Quadrifoglio is capable of sprinting to 100km/h in just four seconds and on to a top speed of more than 306km/h while still being capable of up to 21km/L on the official extra-urban fuel efficiency cycle, with low CO₂ emissions of 189g/km.

Built around Alfa Romeo's all new rear-wheel drive architecture, the Giulia sports short overhangs, a long bonnet, muscular haunches and the longest wheelbase in its segment. Careful management of weights and materials has resulted in perfect 50:50 weight distribution across its axles, while the sophisticated four-arm AlfaLink rear suspension (with an Alfa Romeo-patented solution for toe adjustment) and new double-wishbone front set up have been specifically tuned to maximise its dynamic abilities and enhance driving comfort.

Also debuting on the Giulia is a new semi-virtual steering axis, which optimises the filtering effect and guarantees rapid, accurate steering by keeping a constant caster trail in corners, while the advanced AlfaTorque Vectoring double-clutch rear differential system precisely controls the torque delivery to each rear wheel to improve traction in low grip conditions without having to run up against an invasive stability control system.

Interior highlights include special sports seats trimmed in leather and Alcantara with front seat heaters, steering-column mounted paddle shifters, a 7.0-inch TFT instrument cluster, Alfa Romeo's new Uconnect3D Nav 8.8-inch infotainment system, DAB radio, dual-zone climate control, automatic lights and wipers and cruise control with speed limiter.
