With a list price of $39,150, the Alfa Romeo Giulietta QV is the only variant in its range to feature the 173kW/340Nm turbocharged 1.75-litre four-cylinder engine.
Helping to relay its sporting heritage, the front-wheel-drive Giulietta QV is not only exclusively tied to a six-speed manual transmission, but has also had its powerplant pinched by Alfa’s new rear-wheel-drive 4C sports car – albeit with outputs upped 3kW and 10Nm.
A significant price increase over the $24,550 entry-level Giulietta with its 88kW/206Nm 1.4-litre turbo-four, the QV does come stacked with equipment.
Apart from the obvious QV sportiva badge and logo, the top-spec Giulietta can be spotted from a distance by its tinted windows, chrome-plated window frames, satin silver wing mirrors, tinted headlights, sports suspension, rear parking sensors, twin exhaust, red brake calipers and 18-inch alloy wheels.
The only mechanical changes are the introduction of a new 148bhp diesel engine, while the existing 1.6-litre diesel engine has been tweaked to improve its economy and efficiency.
All of the Giulietta's engines remain punchy and flexibie, and the new 2.0-litre diesel is no different. The power delivery is smooth, and while it's a little grumbly around town, it quietens down nicely on the motorway.
The refined improvements over the old engine are down to a new injection system and the addition of more sound-proofing material. However, once you are up to speed, there's still a notable amount of road noise, although there is minimal wind noise from the streamlined door mirrors.
The 1.6-litre diesel engine might be more economical than before, but it's still very noisy, and a lot of vibration still makes its way into the cabin, too. The reductions in CO2 emissions mean that it drops a company car tax band, though.
The Giulietta's standard six-speed manual gearbox also disappoints, because it has a notchy action – not what you'd expect in a car that has sporting pretensions. It's a shame, because the Giulietta is composed through bends, even if the steering doesn't offer much in the way of involvement.
The ride is also unsettled and unforgiving over most surfaces. Opting for the largest 18-inch alloys only makes matters worse.
The Alfa’s asking price includes the QV’s headlamp surrounds, unique front and rear bumpers, 18in alloys and a 10mm drop in ride height, as well as Bluetooth and sat-nav on a 6.5in touchscreen inside.
