Alfa Romeo brought along the updated Quadrifoglio Verde versions of the Giulietta and MiTo to the Geneva Motor Show. The changes that took place are evident under the hood which receives the newer aluminum block 1.75 liter 4 cylinder turbocharged petrol engine from the 4C sports car.

Producing 237 hp (240PS) and 340 Nm (250 lb-ft) of torque, the new direct-injected engine is just 5 hp more powerful than the previous unit. It will use Alfa’s TCT six-speed semi-automatic dual-clutch transmission, also from the 4C. N

The Giulietta sprints from 0 to 100km/h in 6.6 seconds and the top speed is 240km/h.

The Giulietta QV on the other hand gets exterior tweaks from larger exhaust tail pipes to 17 or 18 inch alloy rims, with front grille, door handles and fog light frames.

The updated model features a revised instrument panel with new leather and Alcantara trim sports seats, and a redesigned steering wheel with white stitching and leather gear knob and parking brake with white and green stitching.

The MiTo Quadrifoglio Verde's revisions are far more modest. It uses a new Magnesio Grey matte paint, different rear spoiler, new burnished finish for mirror fairings, front grille, door handles, headlight frames and 17-inch alloy wheels with red brake calipers.

The interior gets fitted with black leather upholstery with contrasting stitching for the steering wheel, parking brake and gearbox, new instruments with QV logo, Competizione dashboard with "carbon look" finish and new special mats.

Power comes from the same 1.4-liter turbocharged 4-cylinder petrol as before. Producing 170PS (168hp), the unit propels the MiTo QV from 0 to 100 km/h in 7.2 seconds, with top speed remaining at 219 km/h (137 mph).
