Alfa Romeo has released the first official photos of its new flagship Mito and Giulietta Quadrifoglio Verde.

The Giulietta QV is powered by the same 240hp 1750 turbocharged petrol engine as the Alfa 4C, endowing it with a 0-60mph time of 6.6 seconds and a top speed of 149 mph.

It should prove quick through the gears, too, with peak torque of 340Nm available from 2,100rpm to 4,000rpm, although 80% of that is on offer from just 1,800rpm.

Power is sent to the front wheels through Alfa’s TCT dual-clutch transmission, which offers six speeds and a choice of automatic or manual modes, with shifting accomplished either via the gear lever or paddles mounted behind the steering wheel.

Alfa’s DNA driving mode selector allows the driver to choose different set-ups for throttle response, engine output, transmission shift speeds and steering assistance level.

The company says they’ve worked hard to make the most of the aural experience, most notably with the use of a new intake unit.

The Giulietta Quadrifoglio Verde is marked out externally by a new gloss anthracite finish on the door mirrors, grille, door handles, fog light surrounds, side skirts and rear spoiler.

Red Brembo four-piston callipers clamp down on 320mm front discs, and are wrapped in new anthracite alloy wheels.

The interior features new leather and Alcantara seats, sportier instruments bearing the QV logo, plus leather steering wheel, gear-lever gaitor and handbrake lever with white and green stitching.

Black roof lining, aluminium pedals and QV floor mats finish off the look.

To celebrate the launch of the Giulietta QV, a special Launch Edition model is being offered with carbon rear spoiler, front and rear air dams, side skirts, and 18-inch five-hole alloy wheels.  There’s a choice of Alfa Red, triple-coat Competizione Red or Magnesio Grey.  Only 500 are being produced globally, with 100 coming to the UK.

The new MiTo Quadrifoglio Verde meanwhile is powered by a 170hp 1.4-litre MultiAir turbo petrol engine mated to a six-speed dual-clutch TCT transmission.

62mph arrives in 7.3 seconds with a top speed of 136mph.  Economy is pegged at 52.3mpg with CO2 emissions of 124 g/km.

Externally, the MiTo QV features burnished detailing, twin tail-pipes, rear spoiler and revised rear bumper, plus 17-inch alloy wheels, red Brembo brake callipers and a smattering of QV logos.

Inside, there’s a pair of Sabelt seats with carbon-fibre backs, green and white stitching for the steering wheel, gear-lever and handbrake, plus standard equipment that includes air conditioning, cruise control, and Uconnect infotainment system.
