What is it?
This is the stylish Alfa Romeo Giulietta hatchback, equipped with the firm’s dual-clutch transmission. The TCT, as Alfa calls it, was first seen in the Mito last autumn but has already been revised for slicker shifts and an improved stop-start function ahead of this application to the Giulietta.
The six-speed ‘box gets a pair of dry clutches, and works alongside the stop-start system to boast some impressive economy and CO2 figures, which are also helped by its reduced weight.
At 81kg, the gearbox weighs 10kg less than a conventional auto’, and, in this 168bhp 2.0-litre diesel model, offers economy of 62.8mpg and CO2 emissions of 119g/km. Small, but notable improvements over the 60.1mpg and 124g/km offered by six-speed manual-equipped versions of the same engine, then.
What’s it like?
Not bad at all. We only had the chance to assess the gearbox around Alfa’s Balocco test track in Italy, and when resisting the urge to attack the corners, the gearchanges were slick, smooth and fade into the background. Just as a good auto’ should.
Like all Giuliettas, the TCT-equipped diesel has the selectable DNA driving mode system. When travelling at 70mph in N (Normal mode), 2000rpm was indicated, which should make the twin-clutch Giulietta well suited to long motorway cruises.
